Glenbrook Heating and AC has been keeping us cool in the summer and warm in the winter for 31 years. The maintenance plan has enabled us to keep our system longer and our utility bills are lower. They are always responsive to my calls and always show up precisely at the designated time. I highly recommend them for your HVAC system.

Had Glenbrook out to provide a quote for a garage heater. Brad was very helpful, knowledgeable, and professional. Were evaluating the quotes right now and will absolutely consider Glenbrook for our future needs as well.

I can always count on the team at Glenbrook Heating & Air Conditioning to service my units with care. They’re reliable, courteous, and very professional in every aspect. I have found their pricing to be competitive and written estimates complete. Supporting a local business is a bonus when you have a maintenance contract or install new equipment with Glenbrook H & AC.

Glenbrook Heating and Air is the best!! Quick, reliable, and quality service every time I have a problem. Contact them if you need service, you’ll be happy that you did!

Fantastic service. I use their annual service plan and its very convenient. Brad and Jill are great to do business with, and the technician Dominick is knowledgable and friendly.

My furnace stopped igniting and after I, myself did initial inspection, cleaned the igniter and the flame sensor and still didnt help I called for a service.The receptionist was polite, fast and accurate to put down all the details I provided.Dominique, the technician came in 2 hours. Knowledgeable, professional, accurate. He was explaining to me what he was doing. He fixed the problem, inspected the unit and made some recommendations.The price for the visit was $98 visit + $60 work = $158, which meet my expectations for a normal pricing.Thank you, I was very satisfied with the visit!

Super glad I called after another company came and gave me an outrageous estimate. Brad and his crew gave me a much more reasonable estimate right after I called, and checked on the availability of the evaporator coil for my unit. Professional and friendly service from beginning to end. I was impressed with the prompt installation. Excellent local family business. I truly highly recommended Glenbrook Heating & Air Conditioning.

Very responsive and communicative! Always kept me informed and always remained calm, which in turn kept me calm in what could be a crazy situation with a problem AC!

Great technician, they keep us on schedule, reasonably priced and honest. Love that I can always count on them, maintenance or crisis.

Glenbrook Heating & Air Conditioning is the very best. When I inquired about getting a quote for an entire new AC System (i.e., new AC Condenser, Evaporator Coil, and Lineset) - as, I had been told by another local HVAC company that my existing system had a bad refrigerant leak and needed to be replaced - Glenbrook Heating & Air Conditioning came out the very next day to take a look at my specific setup in an effort to provide me an accurate estimate.While Brad (Owner) and Brian (Highly Skilled Technician) where at my house to put together a new system quote, they were actually able to find the refrigerant leak in my existing AC System - simply by looking at the surface of the system - when, one of their competitors had been unable to find the leak even after performing a leak search.After finding the leak, Brad told me that I actually did not need to replace anything. The two gentlemen then left for a few minutes to get the required parts to fix my leak (basically, on the spot), were able to quickly and skillfully fix the leak, and had my AC System back up and running in no time.I truly feel blessed to have found a company with such honesty and integrity. Moving forward, I will be using Glenbrook Heating & Air Conditioning for all of my bi-annual system checkups/cleanings - in an effort to ensure my HVAC system is kept in tip-top condition - and will be using Glenbrook Heating & Air Conditioning for all of my future HVAC needs (i.e., I am now a customer for life).If you want the best service around (i.e., great communication, prompt service, skilled technicians, honesty/integrity, and competitive pricing, etc.), Glenbrook Heating & Air Conditioning is your best choice. Glenbrook Heating & Air Conditioning is a step above their competition and are simply the best around. They are truly in a league of their own.Thank you, Glenbrook Heating & Air Conditioning!

Very prompt and provided good service 👍

Efficient and answered any questions I had!

The worker was polite and efficient in resolving our heating issue. We have used Glenbrook Heating since 1998 for a new 2005 replacement boiler with older radiators and a new AC unit with our ductwork. The owners are great to work with. Highly recommend!!

I have relied on Glenbrook Heating & A/C for all of my HVAC needs at two homes for more than a decade. They are reliable, honest and know how to deal with the quirks of older homes with older set-ups. I love how responsive they are. This local business has values their well-earned reputation. I enthusiastically recommend them to all my friends.

We’ve used Glenbrook Heating & Air Conditioning for 15+ years to provide routine maintenance for our two furnaces & two AC units. They also provided repair services on a couple of occasions. 18 months ago we had them replace the downstairs furnace and AC; last week we had them replace the upstairs furnace and AC. Glenbrook is price competitive, professional, personable, on-time and considerate of the home owner. What more can you ask for?

The technician was awesome, professional and knowledgeable.

Glenbrook Heating & Air Conditioning is like a well-oiled machine. They use an automated system to send a reminder on an upcoming appointment. On the day of the appointment, the system will notify the customer that a technician is on his way. The invoice is sent via email which helps the customer keep a record of the transaction.The quality of the service is excellent. The technicians are very experienced, courteous and professional. Equally noteworthy is that they wear booties inside the house. They’ve been doing this even before the pandemic.The bottom line is my family feels safe with our HVAC system I highly recommend this company.

Glenbrook Heating & Air is very professional! Everything is seamless and organized! Dominic is great in the front lines and Jill is equally as good behind the scenes!

Fantastic company and amazing service! Brad and Jill run a first class company and I would highly recommend. Ive had installs, service, and emergency service all done with GH&AC for the last 5 years.

We began using Glenbrook Heating when we bought our first home in Northbrook in 1979! We have always appreciated the good and honest service we received. We have confidence in the work they do. We wouldn’t call anyone else.

I’ve worked w Glenbrook Heating for years and they are the BEST! From making appointments to the actual service, it’s a pleasure. Always courteous, ALWAYS prompt, honest and helpful. I can’t recommend them highly enough!

Once again Glenbrook came through despite COVID. They were able to schedule an appointment that complimented my work schedule to check my furnace & sump pump in anticipation of winter. As always they were on time, polite, informative, & took COVID precautions. Their staff is top-notch providing quality service and products at a reasonable price. I highly recommend!

Even though I wasn’t with Dominic while he checked everything he also does a very thorough job. That’s the main reason I don’t follow him around. He’s one of the best guys you have although they all do a nice jobGood company to be with. Not always the cheapest but you get your money’s worth

The best. Committed capable 2nd generation family business used 35 years by our family at 3 addresses, 2 currently, one prior.

We have been using Glenbrook heating & Air for almost 30 years. They are a Family owned business. I would definitely recommend.

Glenbrook Heating & Air Conditioning is always courteous, professional, knowledgeable and efficient! We have been using them to service our air and heat for years and they never disappoint! Truly a customer focused company!

My AC went out on a Sunday, they called me first thing Monday and said they’d be out in the afternoon but came early. They diagnosed and replaced a part quick. Very professional and seemed like a very good price.

Always a great experience. Knowledgeable, dependable & timely. Appreciate how easy you make it for us to feel confident that our home is in good hands.

Ive used them for years with their annual service contract and they have done excellent professional work. They have always been there when I need them. Outstanding family owned business!!

Glenbrook heating and air conditioning is the best, no matter what season we are in. They have replaced both my units in the past and continue to service them yearly. They are always timely, both in arriving and servicing. After Dom left today I mistakenly thought there was a problem with my outside hose. He came back after hours to check it out. Turned out to be my issue, not the hose! Couldn’t ask for better service.

Great consistent service

I’ve been using Glenbrook since I became a homeowner 19 years ago. They’re a small, family-owned business and I trust them enough to leave a key for my house. They’re professional, clean, reliable, and keep me cool in the summer and warm in the winter.

On time and professional- great pre visit and after visit follow up

The team was on time and very professional. Wore masks and booties.Keep me updated on what they were doing.Highly recommended.

5 stars across the board. Had A/C unit go down in 90 weather, Jill called back within 30 minutes, and had tech out within the hour. Professional, courteous, and competent. Fixed everything quickly and cost-effectively, and it was clear this organization works with immense sense of pride and duty. Randomly found them online doing local search for Air Conditioning Service Near Me, and it was the best and luckiest Google search Ive ever done for a service organization. Give em a shot.

Top notch professionalism, timely, dependable, fair pricing, straight-forward...and kind.

I trust this company to provide the best product and service for both our heating and cooling systems. Today they installed an air scrubber and I can already tell the difference in the quality of air in our house. Remarkable!!

We have been customers of this fine family business for over forty years. We get great service. That is why we stayed!

Nick was very professional. He checked out the AC and told me everything is fine. I realize that the unit is old and swill need to be replaced soon, but for now he said everything is okay.

Weve used Genbrook Heating and Air for over 20 years. Theyre the best. Always there for you in an emergency and throughout the year with basic maintenance.

We returned to this company after living out of state for a number of years. The service is friendly and efficient. Nick kept in touch because he was running late--much appreciated! He also explained things and, in general, was very professional. We look forward to your service for many more years!

Have been using Glenbrook for at least some 20 or more years. There is no reason to change when work is done perfect. Response on questions or needed service is quick and complete.

We have used Glenbrook Heating and Cooling for almost 30 years. We have always found them to be friendly and efficient.

I was referred to Glenbrook Heating and Air Conditioning by my Mother in law and Brother in law who have each been long time clients. Brian and Nick did a great job on the install of the AC unit. They came on time and were courteous. On top of that I good a good price on the unit

Timely, friendly and great customer service. Big thumbs up!

Everything about this company is top notch! Great service, very honest, efficient, organized. Love doing service with them.

Ive been dealing with Glenbrook Heating since 2014. All team members Ive encountered were professional, courteous, and respectful of their clients time. Ive dealt with Nick this last time. He was extremely courteous, knowledgeable and professional. He provided me with important information about my furnace that I wasnt aware of. He was also punctual and arrived at the exact time of the appointment. He was very clean and left the area spotless. Thank you so much Nick!!!

Recently had both furnace and A/C replaced, all the service technicians did a great job.Today Dominick finished installation of A/C.He did a great job, was very informative as to what he was doing. Everything done well and very neat. Would recommend without question.

We have used Glenbrook heating since 1980. Wonderful family business. Honest, reliable very thorough. I purchase the service contract and have my fall furnace tune up and summer AC tune up. All the service men are friendly, efficient and neat. I wouldnt use anyone else!

Glenbrook consistently provides top service in the annual spring and fall checkups. The main office is also responsive and helpful. The technician who came out today was thorough and professional. We’re glad we decided to purchase our furnace and air conditioner from them six years ago.

Brad came out to see why our furnace was not working and noticed right away that there was a leaf blockage in the intake. Once that was cleared the furnace worked. Very courteous and knowledgeable. Well set up a routine maintenance program.

Glenbrook Heating was there for me. Even through complications, Brad made sure that the job was completed not only to my satisfaction, but to his. That speaks volumes to the commitment and professionalism of the team at Glenbrook Heating. I will use no one else.

Dominick did a great job, again. He called early in the day to tell me hed had a cancellation and could arrive earlier to service my furnace, which worked out great for me. He was quick and efficient, completing the furnace cleaning and check, and replacing the humidifier pad. A very good experience that freed me up for the rest of my day. Well done.

Dominic is always on time and friendly. I feel he is honest and trustworthy.

Just super nice people and they get the job done.

Fast, efficient, personable service. Will use again.

Glenbrook Heating & AC is great. I really enjoy working with Jill, and the technicians - Dominick and Nick are the two I have worked with -- are always prompt, thorough, and answer my many questions. Keep up the great work.

It is so wonderful to deal with a company that is so professionaland responsive to clients needs.

Always professional, responsive, and on time if not early!

The technician could not have known that the circuit board had a crack in it... we called him because the furnace was not operating properly. We had to call in another technician who was more expert who caught the problem and got the furnace working properly

Just had a small maintenance job done by Brian. Prompt and courteous. I highly recommended them before. I have no reason to change.

Ive been a customer of Glenview Heating and Air Conditioning for 20yrs. They have always have been prompt, professional, and affordable. Good people top to bottom.

Ive purchased both HVAC & AC units and now a sump pump from Glenbrook Heating & Air Conditioning. They have been incredibly fair, honest, personable, & professional both installing my new equipment and servicing my past equipment. I would recommend them to anyone that asks. Its hard to find good quality customer service for anything anymore and I thank Brad & team for a refreshing experience time & time again!

Weve been using Glenbrook Heating for at least 25 years. They are always on time, thorough and focused on saving us money where possible. Their prices are very reasonable.

Outstanding professional service! On time, polite, answered all our questions and cleaned up perfectly. Glenbrook installed and maintains our heating and cooling systems and we could not be happier with the price and the professional service. We highly recommend.

This company is the best. They take really good care of me - even in emergencies.

I have used Glenbrook Heating for over30 years and they are terrific.

Had a great experience. Brad is fast yet though. Very helpful in educating us as this is our 1st home. Him and Jill will be our go to HVAC team.

The office response was quick. Nick T, the service tech could not have been better. On time, diagnosed the problem, explained everything. Excellent

Great guys. Their estimate was not quite the cheapest we got, but their product is top of the line and their work was excellent. They replaced our furnace and AC unit in one day and even helped us replace a broken piece of our other AC unit no charge! Would absolutely use again!

They’ve been great, stand by their work, responsive, on time. Thanks!

Great people, great service. Dominick is a pleasant, straight-forward guy. Their office can get a little busy sometimes (which is a testament to their business), but they get back to you and the service and quality of it is excellent. Highly recommend them for HVAC needs.
