Oh wow I was overwhelmed at how good the service was and the price was better that I expected and also the service was quick I well definitely refer to my friends and if I need service again I will call these guys.

Great Guy’s great work all around the bored

Guaranteed Air is reputable, reliable, and trustworthy business for any AC repair, which is difficult to find in this industry. I highly recommend Guaranteed AC as your first call for any AC issues.

Guaranteed AC installed a system in my home. They are always polite, punctual, and professional. Everytime i call, the same technician shows up. He knows the system and the house and that is why i like Guaranteed AC.-Keith

We have a small business in Houston. Our heating stopped working on Monday. We contacted Guaranteed Air Systems after being recommended by a friend. They picked up the phone right away and scheduled an appointment. They were flexible with our availability and came on time. The price was competitive. The technician was punctual and professional.

Have been waiting for a return call for days now and all I want is to get the new ac unit that was put in by you guys 3 months ago fix and working right and not to be put off till whenever you can get to galveston this is far worse company I have ever dealt with

My family and I were experiencing issues with the upstairs AC unit not cooling properly in the middle of summer . If any one has experience the Houston summer heat it’s almost unbearable to with stand not only outside but inside as well. Corey was extremely responsive and efficient with resolving this issue making sure that t our ac was cooling properly the same day!! Thank you guaranteed air for your professionalism and timely response to what may have seemed like a minor issue but you handled with urgency and priority!!

I would highly recommend Guaranteed AC for all your HVAC needs. Great value and impeccable service. We fully trust them for any HVAC needs. Thanks Cory!

I was dispatched to this a/c provider over two weeks ago by my home warranty. Guaranteed A/C never got in touch with me within two business days as promised by the warranty company, even after I left multiple messages with a generic email that did not reference the company. After getting in contact with my warranty and begging for a change in provider after two weeks of this, they assured me that this company would get in contact with me within the next couple of hours or first thing the following morning and more importantly I would receive service as well. No surprises, they did not got in contact with me. I called again and left more messages. Finally by some miracle after over two weeks of trying to get in touch with this company, I called and someone answered. By this point I will admit I was extremely upset and made it known. They were almost non responsive, unapologetic and told me to get in contact with the warranty company if I was upset. They offered to come out the next day which had it not been so long I would have possibly appreciated. But at this point, I had water leaking through my house, through carpet, drywall and even through light fixtures and I made it clear to the guy I was speaking with, again no response other than to call the warranty company. While I understand this is also a huge warranty company issue, I am extremely bothered that whoever answered takes no pride or care in returning phone calls or trying to correct a situation. Please keep in mind, I had a small leak that turned into a much larger situation over those two weeks thanks to the inadequacy and a gross lack of customer service of this company and our warranty company. I now will have to replace drywall, lighting, and flooring. I have never received such incompetent rude service to feel compelled to leave a review, but the negligence in this situation is going to cost us so much money and headaches when it could have been a simple fix two weeks ago.Thanks to another fantastic a/c company, my a/c is fixed, and now the repairs that never should have to have happened will begin.

Very prompt and professional services!

Corey came out and not only quickly diagnosed my A/C needs, but thoroughly explained everything to me. He was happy to spend the time being sure that I understood everything that was happening with my system. I highly recommend Guaranteed AC to anyone who not only wants informed professionals, but also a company willing to take the time to explain the details of the scope of work.

Had a very good and professional experience with Guaranteed changing out my evaporators. Showed up on time and were very thorough. Also helped that the price they quoted was the most competitive I received. They followed up to make sure everything was running smoothly and I’ll be using them going forward.

Great overall customer service. The technicians were very knowledgeable and professional. They explained things in a way that was easy to understand. They answered every question I asked, and even the questions I didnt ask. I highly recommend GUARANTEED AC for all of your ac needs..

This company is so cool! Corey treated us like family.. The quote was reasonable & we got it installed at the house in no time when the unit went out this summer. Fast, affordable & cold air!

Honesty is the best policy and you get honesty with this company. We have made service calls for our primary residence and rental property and recieved excellent service. I appreciate not being up-sold throughout service which is hard to find these days.

Very professional, knowledgeable, and doesnt try to sell you things you dont need. Recommends things that may help with some concerns or issues you may have or experiencing.

Guaranteed Air is customer friendly and ensure they fully take care of the issue. From setting the appointment, pre-appointment confirmations, and follow up, they are very good communicators. My air conditioner was fixed correctly the first time and I have 100% confidence in Coreys diagnosis of my ac.

Awesome Install. Great Unit, Fantastic Price. Was treated like Family. Quick, Clean, Complete. What else could you want. Thanks Again!

Corey is amazing! He was prompt and fixed my ac without a hitch. I would recommend Guaranteed AC to anyone who needs a reliable and honest Ac company in Houston!!

They provide excellent customer service and do an amazing job in a timely manner. I highly recommend this company.

My a/c broke down a few weeks ago and to say the least they saved me a few off my original estimates and did the job properly and efficiently. Corey was very professional, and I have already reffered you guys to a few clients and family members !!

Great service. Very knowledgeable.

Great guy great service very efficient

Had an AWESOME experience with this company!!
