AC needed evaluation after slowly losing its steam over the course of a week. Technician (Tyler) did a thorough job listening to what was going on and evaluating everything both inside and outside. He thoroughly inspected parts of our very old (21 yrs) AC unit before declaring it brain dead. We expected this news, but we’re happy to get someone out the same day at a convenient time. We will use them to quote a new one, someone is scheduled to come next day!

My AC stopped cooling my unit and I was able to get a technician to come out the next day. Tyler was on time and very professional. He explained everything that was wrong with my unit as well as showed photos and videos. He cleaned up after his evaluation and helped me schedule someone to come out and give me a quote. Definitely recommend Guardian

Our technician, Tyler, was super professional and detailed. We wanted to get our furnaces and ac inspected and serviced as it had been a few years. Very happy with the service and honest assessment. Thanks!

We had our A/C, Furnace & hot water heater replaced by Guardian. From Nelson who was the service tech who showed each and every issue with the various components. To Rory and his team of installers. This was an amazing experience. They were professional in each step of the process. THANK YOU! For making something so stressful absolutely STRESS FREE! Amazing Company & people.

My wife and I recently had our AC and Furnace units replaced. Jasper helped us understand our options and was patient and informative with our many questions. Josh, Enrique, and Jose performed the installation and did a wonderful job. They were careful with their tools and equipment and took the time to lay down floor covering and cleanup once they finished. I appreciate that they explained what they did and showed us how to operate the new units. Overall great experience.

Guardian was very responsive to our needs during this busy time. We requested AC services on Thursday afternoon and they were able to come the following afternoon. Nelson communicated his arrival time and was very punctual. He was able to diagnose and fix the issue with our AC and had it working within an hour. We decided to join their loyalty program to save a little on the ac service. We will for sure use Guardian again, especially for our annual hvac checkups. I also love supporting local businesses!

Tyler was very helpful and professional while repairing our air conditioner. I know it was the first hot week of the year, and we were able to be seen relatively quickly. He arrived at the beginning of the repair window and was straightforward when explaining what was wrong with the unit. His professionalism was valued and we hope if there are any future issues with our system that he works on them. We also appreciate that he was friendly and kind to our dog. Thank you so much for the good work!

We have been using Guarding for many years for all our HVAC needs. In a very competitive market, they always deliver top quality service. Sergio Morales was out technician today. He had our issue diagnosed and resolved in less than 30 minutes. Outstanding service.

We love having Guardian as our preferred HVAC and water heater service! They are super professional, courteous, and know what they are doing. I recommend them to anyone and everyone in the Chicago area.

Guardian is the best. The technicians (Tyler and Larry) are fantastic, they educate, do a thorough job and are so helpful! I feel at ease knowing I have them for my HVAC maintenance.

Shout out to the Jasper, Enrique and the guys at Guardian for doing an awesome job replacing my furnace this week. They always take care of any issues in a timely manner and bend over backwards to be accommodating.They designed, installed and have maintained the HVAC system in my home for the past 14 years. I highly recommend them to anyone considering repairs, replacement or just annual maintenance.Thanks again guys for doing a great job and being more than accommodating with all my questions and concerns!

This is our second time (in a few years) using Guardian Heating & Cooling and we could not be more pleased! Tyler, our expert technician, was able to diagnose the problem with our unit in a short time AND present us with multiple options to fit our needs/budget. The communication is excellent, they are fair priced and they are seriously impressive their customer service. From booking to billing, it was seamless! Tyler also gave us the great advice to take advantage of their membership program and I could not believe the savings!!!! Happy to say we are members of the Guardian Heating & Cooling program. This is the level of service you need!

Tyler came out to our place and was awesome. He was very professional and knowledgeable and resolved our issue quickly. We will continue to use Guardian for heating/cooling.

Of all the contractors, repair people, and home improvement companies we’ve ever worked with, Guardian has been the very best. Their response and follow up communication is top-notch, and they are absolute professionals in installing and assessing HVAC issues. We’ve had their seasonal maintenance contract for many years and 3 different residences, and it has paid off at each. We also contracted them for a very complex job, and they worked through difficult electrical issues to make sure everything worked, coming back to our house -- with no additional fees -- numerous times to find a solution for us. They are honest and upfront, and it’s the best experience we’ve had with any service company. I’d recommend Guardian to anyone.

Tyler came to my house within a few hours of calling. He was able to diagnose the issue with my air conditioning, check the age of my entire hvac system and talk me through the best path forward. As I agreed putting a bandaid on a 23 year old unit is not worth the cost, he helped guide me to programs that will save me money on the replacement.Would highly recommend

They were able to repair our AC in about 2 1/2 hours but the price was shockingly high. Not only was it way more than I expected, but the $89 service fee was still charged. In my past experiences with other companies, a service fee is absorbed into the labor cost if you proceed with repairs after diagnosis. I would not use this company again, there are others that charge less for repairs.

Very poor customer service. Our unit was 90 degrees with a 18 month old at home and they wanted to charge $500 for a Sunday “emergency” visit. We opted to spend $150 for a hotel room and a different company to service our unit later that evening.

Sergio was great! Fixed our issue extremely fast and provided a lot of very good advice!

Sergio is WONDERFUL!! Very professional and determined to help a customer in anyway he can. He was able and WILLING to think outside the box to get my system running. He was willing to take the extra time to get the job done.I will be recommending Sergio and Guardian Heating & Cooling Service from now on!!

They came very fast, and checked the entire AC system, fixed an issue and provide some good practices of using AC. Good service.

Tyler was incredibly prompt and helpful. He was informative about what was wrong with our AC and offered the most cost-efficient ways to repair the unit. Will definitely be using Guardian again.

Guardian was referred to us by another contractor and I couldnt be more appreciative of the referral. Jasper was wonderful and patient from our initial tech visit to helping us select new equipment for our home. The crew that installed our equipment was impressive, cleaned up after themselves (the lead tech said treat this like your grandmas floor). Theyve been impressive in their follow through to ensure were a 100% satisfied. From start to finished, I felt our best interest were taken into consideration.Guardian, youve set the bar for customer service and satisfaction.

Service HVAC Tech Sergio was hands down awesome. Professional and On Time. Called 30 Minutes in advance of arrival. Upon arriving he was ready to go. Mask and gloves on!! Diagnosed the would be problems and narrowed it down within 5 minutes. Explained in Detail the problem and how to fix it. I highly recommend Guardian Heating & Cooling Service for all your HVAC needs and want to send a big shoutout to Sergio !!!

Guardian Heating & Cooling is the most professional, courteous and biggest value for the money. Jasper Pitrello, co-owner, is hands on and if there is an opportunity to save the customer money he will step in. They have replaced our furnace, heater and assisted with our air conditioning. There is value in their monthly subscription as you save money on services and they come within 24 hours or less, in most circumstances. I cant recommend this company enough and have told all my neighbors about how great this company is. Easily a five star company.

Tasso has now helped me at 2 different properties with fixing/maintaining my ductless AC systems. He is crystal clear with all of the terminology and meanings that you know exactly what he is doing and how long he expects it to take.This company is top notch overall and the only place I go now!

Service provided by Nelson Roman was excellent. He was very thorough and patiently explained everything, providing photos and purpose of all parts of the equipment. He also took the time to explain all my options.I would highly recommend.

Tyler did an amazing job sizing up the AC issue and fixing the problem. He was able to come out to the house in less than 24 hours after I called for an appointment. I will be using Guardian exclusively from now on!

I highly recommend Guardian Heating and Cooling. They supplied us with great options for a new ac unit and were able to fit us in the next day for installation! Jasper was great to work with and the installation was very well done.

I was able to get a same-day appointment. My technician, Nelson was thorough and communicated along the way. I would highly recommend Guardian Heating & Cooling Service.

Tyler was very professional and knowledgeable. He walked me through everything he was doing and gave great recommendations moving forward.

We had an issue with a leak with our HVAC system, and we are so thankful for Guardian. They were able to come out within a few hours while all other companies we contacted couldn’t come to fix the issue until the following week. Our tech, Tyler, did such a great job fixing our HVAC system quickly and ensuring our A/C was back up and running in the summer heat. We will definitely be reaching out to Guardian in the future for assistance.

I called to have my heating and cooling checked in a new condo I just moved into. Tyler came out and did a great job. He really went above and beyond. The AC units I thought were mine were not. After a long search, we finally found mine on the roof. But if it wasn’t for Tyler’s persistence and willingness to try, I would not have been able to get it evaluated and would have needed to schedule another appointment. He looked at both my heating and AC. I would definitely use this company again.

Guardian was top notch from appointments, sales, to installation. Everyone was friendly, on time and extremely professional. Ive used MANY other companies through the years and am so grateful to have found Guardian.

Our furnace stopped working during extremely cold weather, of course. Guardian tech was here the same day. He showed us the issue, explained the problem and answered all our questions. The salesperson was not high pressure; was one of the co-owners. He showed us what was recommended based on square footage of our home, gave us his thoughts on what was a good value and investment and what was extras/nice to haves. They helped with the paperwork for the energy efficiency rebates. The installation team was friendly and efficient. They walked us through everything, including programming the thermostat with our phones. They also provided us with space heaters to use to get us to the next day when they installed our new system. We are happy to support our neighborhood businesses.

When our AC gave out in the middle of a 90 degree week, we were pretty worried it would be a costly repair. Guardian was able to send out a technician quickly, and Peter got right to work investigating the problem. Getting the AC back on ended up being a quick fix, but while he was here, he also made some repairs to the furnance and gave me information about replacing it in 1-3 years. We joined Gaurdians membership program and were able to save $700. Excellent value and service, love that they stand behind their work. We will be using Guardian for future HVAC repairs and replacements. Highly recommend.

Today, Guardian Heating & Cooling serviced our AC. It was a pleasure to work with a professional technician that diagnosed the problems and clearly explained what was wrong and what was needed to fix it. I was given options. The work was completed quickly. The technician was Tyler Futch. I highly recommend this company.

I had a great experience with Sergio from Guardian Heating and Cooking. I had an HVAV issue that they were able to respond to the same day I needed service. Sergio was polite, patient, and very informative. He explained to me what he was doing in order to diagnose the issue I had with the heat not working. There were no surprises at all with the closet as Sergio made me aware of what he thought it would be prior to getting the parts required. I am a very satisfied customer. I would strongly recommend Guardian. If all of their technicians operate with the level of professionalism that Sergio does you will have a positive experience.

Tyler was very responsive, quick, and helped me understand the issue. Great service!

We had an amazing experience with Tyler ! He fixed the heat in ten minutes and then did a thorough check and explained so many things about the system that I did not know. We so appreciate the quick reply’s and thorough response. Tyler deserves all the praise for his service and expertise! So grateful for Tyler and the overall experience !

My longtime HVAC people stopped doing tall ladders to get up to my roof, and I found Guardian is one of the only firms to still offer this service. They were on-time, explained things clearly, and identified a component that was ready to fail and needed to be replaced. They installed it immediately so no additional appt required. I’ve signed up for their regular maintenance service. Very professional.

Tyler was very helpful in explaining my HVAC options, as I am a first time homeowner! He took the time to walk me through each piece of equipment and helped me schedule an appointment with a consultant for my next steps.

Nelson and Phil repaired our furnace today and we couldn’t be more pleased. They arrived on time, were courteous and efficient and I would not hesitate to recommend Guardian to anyone needing heating or air conditioning service. An excellent company with outstanding technicians.

Nelson was professional and efficient. Great service and knowledgeable. Will use again and recommend to others.

My first time using this company. My furnace has been acting up so I googled HVAC + my zip code. Guardian came up as a top 10 in my area on Yelp. After reading the reviews, I decided to go with them. I was able to get same day service. Awesome on a 10-degree day. The technician, Nelson, was very nice, professional and informative. You couldnt ask for anyone better. Im hoping the next time I need help with my furnace I can request Nelson specifically.

I had a competitor out to look at my furnace. The competitor quoted me $2000 for the fix and recommended a brand new unit be installed. I called Guardian for a second opinion. Jasper was at my place the next day and probed about what was happening. He proactively suggested he have a look before just providing a quote for a new furnace. Upon review, Jasper said I absolutely didn’t need a new furnace - and that the repairs would be a couple hundred dollars. Jasper was thorough and professional. He also explained what he looked at to demonstrate that the prior assessment of the issue was incorrect. Thanks to Jasper, I saved a lot of money and hassle. I’d highly recommend.

Working with Jasper (company owner) was great. He came over to my house twice - the first time to diligently review the issues I was having and the second time (which he volunteered to do) he came by with a Carrier technician to ensure all questions I had were answered to my satisfaction (which they were). Jasper went the extra mile and earned my business. The only complaint I had with the experience was with the day of install. The crew, while nice and professional, didnt listen to our repeated requests to keep our front door closed, which got pretty annoying. They finally got it but it was after we reached the point of exasperation with them.

Ive used this company for 2 years and have had a positive experience every time. I appreciate the break down of information in terms I can better understand how my HVAC system works.Their tech Nelson was very helpful as so were Josh and Akeem who installed the new furnace, air purifier and humidifier in my condo unit. David was great in explaining what my options were for my needs in the living space I currently own.I am completely satisfied with the work they did and excited about being able to control the humidity levels and limit allergy provoking particles in my home.

Highly recommend. Professional, quick, and very informative. Most people would just come into your home, complete the work, and leave. Not Tyler. He took the time to walk us through what he was doing, the value add of his business, and some best practices as new home owners.

Tyler was great, he explained the whole process and was extremely polite, he used a mask and shoe covers to come inside the house.Recommended repairs, will use this company for the repairs.

Nelson was great. He did a thorough check of our boiler, explaining every step and educating me about the system. He also adjusted our radiators and I noticed an immediate difference. Id recommend Nelson and Guardian to anyone. Super professional, skilled, and helpful.

We recently bought a new home and our furnace almost immediately broke. Sadly the manufacturer and the installer would not stand by the warranty. Guardian came out promptly and identified the issue and gave us several options on how to handle the problem. They never tried to upsell us! They gave sound advice and helped us through a tough process. Once we decided to move forward with a replacement unit, Guardian prioritized our issue since we were experiencing extreme weather and began the process. Every technician, especially Jasper have been extremely communicative, patient and accommodating. The day we called to schedule an installation, Guardian came out the same day to removed the old unit and the very next day installed the new one! I cannot recommend Guardian enough. They are trustworthy, thorough and truly the experts in HVAC systems. Thank you, team for getting us through extremely cold weather!!

Tyler was amazing to deal with! He did all of the little things that make a big difference - polite, punctual, explained the problem really clearly and was just all round a great representative for the company. On top of that he fixed the issue in a very short amount of time and seems very knowledgeable. The previous day I had a different company out that completely misdiagnosed the issue and tried to sell me lots of new parts that I clearly didn’t need. So glad I called Guardian for a second opinion and will be using them exclusively going forward.

The people weve dealt with at Guardian have always been personable, explained things to us, and provided prompt, efficient service. Living in an old house with funky things we dont fully understand, like radiators and boilers, its been a learning curve, but we feel comfortable with Guardian guiding us along.

Called to set up a commercial visit. Spoke to a woman on the phone and asked her about service for a commercial building. She sounded like she had an attitude and then she told me that the company does not do commercial work, when there is an entire section on the website dedicated to commercial services...

Very professional & he explained everything step by step.

Tyler was here to clean and check of HVAC systems. Very thorough and professional. I would recommend.

The service I received from Guardian Heating & Cooling was exceptional, greatly due to Tyler’s professionalism. You can tell he takes great pride in his job. He took all the necessary precautions for safety with covid, was pleasant, and very transparent as to what were urgent repairs and why we needed the repair. These guys will be my go-to for my furnace and, in the spring, for AC work!

Our furnace stopped working. It was on a Sunday evening and temps were dropping! I called the company and received a call back from a technician almost immediately. Nelson showed up earlier than expected and began to analyze our problem. Within a few hours he had our heat back on, working better than ever! He replaced two parts and offered us a maintenance plan. I am so glad I called Guardian. Nelson was super professional and very skillful in diagnosing our problem, which we thought had to do with our thermostat!This company delivers great service and I will definitely use them again!MichelleOld Irving Park

This company came highly recommended so I had them come to do a furnace clean and check. They came and did not properly clean or check the furnace. The tech said there was an oil leak and gave me a quote of 2K to replace the motor. He said he would email pictures of the oil leak..., those pictures never came .He also encouraged me to pay another 100.00 to become a member. I called the company and they said I was doubtful the service was performed properly, they said they would send someone else, I waited all day on the day of the appointment. Nobody came.They sent a salesman to talk to me about my options and he saw the furnace had not been cleaned. I called another company, the furnace was fine, no leak and they properly cleaned it with a vacuum and checked using meters which was not done by Guardian. I am glad I got a second opinion, turns out I do not need a new motor or furnace. I am pretty horrified that the Guardian tech would lie to me.

I called Guardian around 10:00am because my AC wasn’t blowing cold air. They told me that they would be out by the afternoon, less than an hour later Tyler called and said he was on his way. He was able to get the air working within an hour. Very professional and very pleasant to deal with. I highly recommend this company and especially Tyler who is very knowledgeable and explained everything to me that he was going to do and what he did. Thank you!!!!

My experience with Guardian was first class. We needed to replace an aging HVAC system and Jasper helped us with the solution and at a fair price. I would certainly use them again!

Tyler did a great job both in explaining my options and doing the repair. He doesn’t try to up sell services that you don’t want or need. He’s also very good with dogs.

A great experience from start to finish. Easy to schedule, arrived when they said they would, reasonably priced, and Tyler, my technician, took the time to explain everything to me and answer all my questions. Appropriate COVID precautions were in place throughout. Wouldnt hesitate to use Guardian in the future.

My air conditioner decided to stop blowing cool air. I called Guardian on.a Sunday night and was able to get someone out the next day!! I lucked out big time as the gentleman who came out, Nelson, was FANTASTIC! He was determined to get to the bottom of it. After toiling on the hot rooftop, he diagnosed the problem and replaced the necessary parts. He concluded no freon was necessary. So conscientious and diligent in his approach!! I am so happy and grateful for the great service. I will definitely call Guardian when its time for the furnace check. Thank you!!!

Promptly repaired my a/c

Tyler F. fixed the issue with my Rheem furnace. He was incredibly knowledgeable and efficient! Will definitely recommend Guardian, specifically Tyler, to all my friends and family for HVAC needs.

I called Guardian based in a recommendation from a long time customer. Im very impressed and pleased with their service. Jasper looked over my existing HVAC and water heater, asked what I wanted and explained everything in great detail. I was confident that I would receive an efficient and reliable replacement. On installation day, Dan, Enrique and Andy were true professionals. It was a difficult and small area, but their workmanship is top notch and they spent extra time to get the job done right, no compromises. Im very pleased.

Tyler did an excellent job in providing maintenance for two furnaces in my home. He was very professional, knowledgeable and took time to explain details to me in a respectful, cordial, and informative manner.While there was snow on the ground outside he was conscientious about removing his shoes on entering my house and I’m leaving the area in perfect, clean order.On top of all the above, he was super nice! Kudos Tyler, and Guardian Heating.A well earned five star recommendation!

Tyler was an awesome technician. Kept us informed along the way and educated us on HVAC items. Guardian was easy to schedule with and the membership is well with the monthly payments and paid itself off on the 30% discount received on our replacement parts. Highly recommend!

Pat was the technician they sent me. He was able to get the job done without delays. He even labeled things so if any technician came back they can find things more easily. I picked the company because my neighbors used them and Im happy with that decision.

Nelson was great. Very informative and thorough. I informed him that I am a first time homeowner and he took the time to explain how to maintain HVAC and what each part does! After the visit, a report is emailed to you about your system! Highly recommend!

They replaced my undersized furnace with a new appropriate sized unit. Gave me different priced options to choose from. Showed up soon thereafter to do the work and finished the job on time. Work was professionally done and all questions were answered on how to use the new system. Thanks to Donny Akeem and Jasper for all the help!

Guardian is a fantastic company top to bottom. They exemplify great customer service and professionalism. David, Jasper, Sergio, Rory, Michael, Larry and Enrique were attentive, honest, clean and thorough. I highly recommend employing them for any HVAC system needs. You definitely get what you pay for!

Always pleasant dealing with this company. Extremely responsive, quality work and always thorough.

Tyler was a delight! He was efficient and communicative while working, maintained (Covid) safety protocols, and became best friends with our very attentive dogs. He went above and beyond to help us search the air ducts for a lost item. We’re very appreciative!

We were careful looking at options for a new A/C unit in our first home. It’s a big purchase, right? We appreciated the patience and respect from Jasper & David when they visited us to talk about the estimate. They took time to look at our unit thoroughly rather than focusing on the numbers.On the day of service, we had Don and the crew install the unit and they were beyond amazing! Polite, friendly, knowledgeable, and even sensitive around our 1yo —warning about the noises and safety hazard particles. I mean those details to share while flying up and down the stairs all day long with the heavy equipment? That’s the winner service. Most importantly our baby loved Don for singing with her while working. Absolutely recommend Guardian. Thanks again!

I dont do reviews unless service is worthy of 5+ stars or 1 star.- This is the only company in the area that charges 1.5x their normal rate on the weekends.- This company repeatedly told me that the part needed to repair my furnace was $650+. After searching online for parts and speaking with other companies, I found that the part was $300 with labor and trip fee included. So when you add in the $150 for the trip fee, Guardian charges 2.67x more than other reputable companies. That is not fair pricing by any means. No one in their right (business) mind would pay almost 3x more for a simple parts & install job.- I asked for warranty on parts and labor and was told they do not provide a warranty. (1.5x trip fee on weekends + 3x job fee vs other service companies + no warranty for the work)- I was told that the part may or may fix the issues, which already plants the seed for more cost at a 3x rate- the rep also discussed my decision with my tenant. I believe that a business should deal with the property owner / individual who requested the service. It is not that companies place to discuss financials or decisions with a tenant or resident. The rep did not mention that I declined the job because of inflated price, lack of warranty on parts, lack of guarantee for labor. Therefore my tenant became angry assuming that I merely declined the service due to price alone.I would recommend Lakeview instead. The rep at Lakeview laughed at the quote that I received from this Guardian Heating & Cooling. They came out promptly with the part needed to fix the issue at a fraction of the price. Very very pleased with their service. Unfortunately, I still had to pay Guardian an inflated price for the diagnostic. Lakeview diagnostic price is half of Guardians.

Nelson came out to assess our HVAC system on a house we recently bought and are about to move into. He was awesome! He called me about 30-40 minutes before he arrived and was on time. He was very professional and dealt with my dog barking and being annoying at times, which was much appreciated. He was helpful in explaining all the repairs before he did anything, which I appreciated, and even helped us fix a few minor issues while he was there (such as the weird settings on our thermostat). Overall, very satisfied with the service!

Tyler was so professional and incredibly knowledgeable in terms of the type and condition of my furnace, future maintenance, and Guardian’s commitment to their customers. I have always had a great experience with Guardian and will continue to use them and recommend them to others.

Peter was tremendous. Our plumber had declared our water heater dead. Peter came out with his friendly assistant Matt to haul it away and hook up a new system and he fixed the unit instead, in much less time and at much less cost! This is the kind of trusted service you look for in the skilled trades: attending to and solving the problem, not looking for sales. We were *very* pleased with his work.

I am not really a review person but when it comes to the Guardian team I felt like I needed to spread the word. The Guardian team installed my new water heater and starting with initial professional and thorough estimate and finished with the installation process I must say that the guys did an amazing job. The whole crew was professional, knowledgeable and on time. The contact people Jasper and David were always very responsive and answered my countless questions about the project. I truly recommend Guardian to everyone because they are truly reliable professionals .

I want to write a great review of Guardian Heating and especially of Liz R. Although I have not used their services, I hope to in the future. Why I can still recommend them is because I am certain they are an honest business. I lost my wallet on the street and Liz picked it up, tracked me down via Facebook, and returned it to me. Nothing was missing and she refused to take any money. Isn’t this the kind of business you would want? I recommend Liz for Employee of the Month!!!

Technician was very knowledgeable and courteous. Completed the maintenance and supplied a quote for additional work that can be done at a later date. Very satisfied and would recommend them to my friends and neighbors.

What a great experience. Tyler was incredibly informative in a way that didn’t feel condescending and he walked me through every Step of the process. Definitely will be a long time customer

Tyler from Guardian Heating and Cooling came to perform the seasonal maintenance on our heating system. He was very friendly, knowledgeable, professional, and covid-courteous. He answered all my questions and performed his services in a very timely fashion. I definitely recommend working with Tyler at Guardian Heating and Cooling.

Tyler came out to service the furnace and check on some AC issues we were having. He was friendly and knowledgeable and took care of our issues in short order. Id gladly use Guardian again!

Tyler came over to perform the yearly maintenance inspection of my furnace and was super thorough and informative! Tyler took the time to ask me questions about how my furnace was performing so that he could pay special attention to certain details. After the inspection and cleaning was complete Tyler showed me what he found, and even documented some things by taking pictures of the furnace interior. I love that Tyler took the time to educate me about some key aspects of my furnace, such as how its use affects air quality and ways to mitigate its effect on my utility bill. I’m happy to have the maintenance plan with Guardian.

Tyler was very knowledgeable, friendly and went out of his way. He definitely knows his job! Highly recommend Guardian!

Peter provides thorough and timely service. This was the second time he has performed service for us. He does a fine job and we appreciate his work.

Tyler was professional, informative and efficient. He clearly explained costs and the work completed. He informed me of the membership program as well. I will continue to use and recommend Guardian!

Tyler was great. On time, professional, explained everything and was good humored as well!

Super great service! Tyler was super helpful and informative.

Outstanding service oriented company with highly professional and friendly staff. Ive used them several times for annual checkups and/or maintenance work. This year a young Guardian serviceman named Tyler checked out my boiler over the course of about an hour, pronounced it in good shape and then convinced me to sign up for a reasonably priced maintenance package that covers the boiler and water tank, as well as offering substantial discounts on any needed repair issues. In the coming cold weather, its good to know that I have Guardian at my side if needed.

My AC had a blown fuse and I replaced a new fuse. I was looking for a replacement because the technician from a different company said that the compressor is done. I called Guardian Heating & Cooling Service and requested for a quote for a new AC. The technician came to my house and fixed the problem. I would not hesitate to recommend and refer my friends to this place!

Dudes that come are always friendly, on time, and always willing to educate and keep me informed on what’s going on. Good people. Ladies in the office are funny too. Happy with the service.

Tyler the technician was very professional, has a personality that makes you feel confident that the right things were going to be done. He was knowledgeable and appeared to be working in a systematic manner to find the cause of the ac problem. He had no problem working on a slanted roof where the unit was located. He exhibited a hard work ethic. Being a first time customer with Guardian, Tyler left me with a very positive view of this company. I will be calling them for future heating and cooling needs.

Sergio was here first thing in the morning and repaired our air conditioner right away! He was also very respectful of our space, and did everything to maintain distancing and keep the service as contact free as possible. Very happy with his work! Thank you

Tyler was incredibly professional and courteous. He was consultative throughout the inspection and walked us through the current issues with our furnace + A/C and advised on how best to handle future maintenance as well. Highly recommended!

UPDATE: Ive been a Guardian member for a year, and couldnt be happier. The service has been fine (nicest techs!) but, last week, I found out that Id have to replace my A/C. Jasper came out to go over what Id need and, with no sales push at all, I realized Id be wise to go ahead and replace the entire HVAC.This morning, Rory (lead) and Akim arrived to install my new system. Theyre a real dream team. Though I was working from home, they did not disturb me. Hard as they worked, they never seemed to break a sweat, and always had a ready smile. The cherry on top? They left my home at least as clean - probably cleaner! - than they found it.If youre looking for a quality, fairly-priced HVAC contractor - call Guardian!____________________________________Out of the blue, my A/C stopped cooling. Time to call Guardian! Sergio, my service tech, was A+. He arrived right on time (masked), worked efficiently and professionally, clearly explaining the issue (coolant leak), and was considerate (even asking if he could write on my wooden table). I happily signed up for the membership plan, and only hope Sergio is back in the Fall to check out my heating unit. Hes the best!

They did a fantastic job repairing our 20 yo furnace that went down on Christmas Day. They were quick efficient and friendly. I’ll be using them for regular maintenance from now on.
