HVAC reviews in Tucson, Arizona

Air Quest has serviced my equipment for about 12 years. They are the only company that I trust for service and repairs. Very courteous and professional receptionists- -always friendly! My technician Louis did a great job diagnosing concern, performing spring service and repairs. Also, discussed concern with owners and I trust their recommendations. Air Quest is the best!!

Air Quest Heating and Cooling is always a pleasure to work with. They installed my Air Conditioning unit 13 years ago and are the only company I would trust to maintain it. They always arrive promptly when I need service, are friendly, professional and always do a magnificent job at a very reasonable price. I highly recommend them for all your AC/HVAC needs.

Aaron is perhaps the most intelligent and engaging HVAC owner in Southeast Arizona. He truly understands the finite details of his trade and designs systems perfectly suited to residential, commercial, and in my case, research settings. His field install teams are skilled and flexible, willing to work in unusual settings with patience and humor in what can be a challenging work environment with temperature extremes and tight spaces.

I have hired AirQuest for three projects over the past five years, and will again and again.

Quest Heating & Cooling. Aaron Romero, the owner, was professional, honest, and extremely knowledgeable from start to finish. He took the time to explain everything clearly and made sure the work was done right. The service was prompt, reliable, and fairly priced, which is hard to find these days.

You can tell Aaron truly cares about his customers and the quality of his work. The whole process was smooth and stress-free, and my system is running better than ever. I highly recommend Air Quest Heating & Cooling to anyone looking for dependable HVAC service. Thanks again for the excellent support!

Thank you so much for coming out and saving us on Mother's Day! We appreciate your speedy service!!!

Mark's work is always reliable, fast and professional .Would highly recommended.

Mark was very knowledgeable, responsive, and professional, which altogether made for an extremely positive experience - highly recommend!

Extremely professional, punctual, honest, and personable! I would recommend Mark & his company to anyone needing heating & cooling services!

Absolutely the most trustable, reliable, skilled, and diligent tradesman that I have ever known. The epitome of an honest business.

Mark Sunderman, the owner of Summit Cooling & Heating is professional and first class. He engineered and installed a new American Standard HVAC system for our mid-town 2200 sq. ft. home. This new system replaced a 15 yo Carrier unit which was over-sized and getting a bit cranky. Mark took the time to ask questions and find out what type of system we wanted. He educated us when we were unsure of available technology options. Mark thought outside the box and installed a system which is correctly sized for our house (a very important point). The entire system was installed with no 'rough edges'. It has performed flawlessly since May of this year (2014). When a small sensor adjustment was required, Mark responded within a few hours. If you are looking for a properly sized, well engineered and professionally installed HVAC system, speak to Mark Sunderman at Summit Cooling & Heating. He is committed to building a lasting relationship with his customers... Paul E. Floro

The Summit team just finished a complete replacement (and re-engineering) of my system (dual compressors, evap, cond, etc.). High quality workmanship, on schedule, on budget, results far better than when the system was originally installed. Team was polite, clean, organized. Highly recommend Summit.

Mark and his crew are excellent! A metal duct repair that looked to me like it was going to be a real pain ended up easier than expected. They found a creative way to access the trouble area without having to gut the ceiling. He doesn't try to upsell you for work you don't need. Will use again when needed for HVAC work!

Excellent service! I couldn't be more happy with Summit Cooling and Heating. I called right before closing and they were able to send someone out the next morning. Mark, the technician, was patient and thorough. He explained the issues of the AC and ensured all parts were working once again. Summit is my go to for all my cooling and heating services.

Mark and his team are so knowledgeable, responsive, and respectful. We have worked with them to service our equipment, soundproof a noisy HVAC closet, and deal with a condensation issue. Hard to find this kind of quality service these days! 100% recommend.

Got recommended to Summit from a friend and after reading the reviews decided to call them for an intermittent A/C problem.
They showed up but could not find anything wrong and recommended we call them again when there was a problem. Called them twice after that but they said could not come because they were busy. Ended up calling a different company and they found out what the problem was very quickly. Ended up replacing the unit.
Would not recommend Summit to anyone. Would give them 0 stars but minimum is 1.

I had an 18-year-old unit, decided to replace it before it was an emergency. I had three companies out, I was shopping for expertise first Price second . Summit cooling was recommended by a friend after I expressed my dissatisfaction with Costco and the other proposals which I had received. Mark came out and his proposal was comprehensive. He spoke to me in layman‘s terms to help me understand options and make an educated decision. The paperwork he left me to go over was very informative. So I hired summit to do the job. These guys are practicing their craft at a high-level. His son Tyler was the lead man on the installation professional and attention to detail. Mark said he would come and service the mini split in my Arizona room when the job was complete no charge . He came to service the mini and pick up his check I had left for him .When I returned home there was a note on the counter with the check . I was being credited with $489 for cash discount. I thought it was already reflected in the balance. I surely would have never known the difference. Definitely five stars .

Best AC company in Tucson. My house has never been so comfortable and our electric bill is way down too (we bought a new unit). Great people and great work! Thank you!

Summit Cooling and Heating recently replaced a 17 year old heat pump system at my home. They did an excellent job and I'm very happy with all aspects of their work. I would certainly use Summit again.

Before selecting Summit to perform the work, I received quotes from other service providers. Summit's owner visited my home and thoroughly analyzed my Tucson specific cooling and heating requirements. He provided a very detailed explanation of the recommended work and answered all my questions. He offered numerous options to replace the system; however, I wasn't pushed towards a particular solution.

Summit's written quote proved to be both the least expensive and best value solution. No attempt was made to add services or additional costs after we accepted the quote.

Summit's two-man installation crew was very skilled. All work was professionally performed and they showed me how to operate the new system. They kindly answered questions about a second HVAC system at my house that had nothing to do with the install work under contract.

Summit provided me with the promised 10 year warranty in a timely manner and remains responsive to my calls. I'm confident they will standby their work as time passes.

I am very pleased Summit Cooling and Heating.

We decided it was time to replace our 23 year old system with something more efficient. Mark did an extensive evaluation of our house to determine what system would be best for our needs. He explained why he picked the system he did and what to expect during installation so there was no surprise's. When it was time for the installation, Marks crew was polite, professional and did an amazing job. We could not be happier with our investment.

We highly recommend working with Summit. Mark came out early in 2025 to help us understand our options (size, placement, gas/electric, etc.) for replacing an old system. It took over 6 months for us to resolve other house changes to make room for the new HVAC. Mark never pressured or pushed us and quickly updated our options when we were finally ready. We have been using the new system for a couple months and it is great. The cost was similar to other quotes we received in town, but the work was done well, on time, and with very competent and friendly technicians.

Roy was fantastic always professional and found the source and fixed it in less than 10 minutes Thank you also your receptionist was professional and was very caring and very helpful
