    Excellent service all around! My AC unexpectedly quit working late in the evening. Arizona heat is…read morebrutal! So I quickly searched Yelp and found Chill Doctor. The tech was able to get out that night, awesome! He was very knowledgeable and he was honest with my situation, letting me know that full replacement was not necessary and explained the repairs and options in detail. I will be recommending to friends and family but I hope they're never in my situation! Stay cool my friends!

    If you need HVAC work done and want a local independant business owner, operator who is extremely…read moreknowledgeable, competent, on time and works into the evening to finish a job call Chill Dr. When our old air conditioner/heater quit we looked on the internet for some one with a good rating. We were looking for a repair and Chris was willing and able to do it. That evening we discussed it. Because the age of the unit the next day we asked about replacing it. Chris seemed surprised that we were considering that. His estmate was lower than prices we had been told by others who had similar units replaced. Then after the rapid install of a name brand unit with a 10 year warranty the final bill was significantly less than his original estimate. He left everything neat and cleaned up. He is fair and honest in addition to the other things noted!!! We could not be happier or more pleased with the quality, price and timeliness of the work done by Chris of Chill Doctor HVAC.

    It is with great pleasure that I write this review. CJ from…read moreIDEAL AIR CONDITIONING & INSULATION was at my home in Mesa, AZ on May 6,2026 to solve our cooling problem downstairs. He was very punctual, patient, professional, very honest and extremely knowledgeable. He completed the entire trouble shooting, diagnosis & repair, (Furnace Blower wheel and Blower motor) replacement expeditiously and at a fraction of the cost from other companies- a huge savings for us and most importantly, our unit is working perfectly!!. He also offered us a very affordable ongoing maintenance package. We have lived at our home for 12 yrs as first owner, several companies have done AC maintenance and repair jobs at our home with disappointing results. IDEAL AIR-CONDITIONING is truly "ideal" from the front desk dispatch staff to the very competent technician on the job site, it was a seamless and flawless experience!. I wholeheartedly recommend IDEAL AIR CONDITIONING & INSULATION for anyone in the valley with HVAC issues who needs a highly reputable company. Thank you "IDEAL AIR"

    Our A/C units are 29 years old and are starting to go out. As a result I inquired with a few HVAC…read morecompanies to get quotes on a replacement of two units. Alex (owner) was incredible to work with. He came out to our property and did a full evaluation. He caught things that no one else did. One thing that stood out to me was his transparency and honesty around the setup of our systems. We have old suction lines and liquid lines that are not compatible with the new Trane units. He has a solution for that but he was the only one that mentioned this. Some of the other installers that I inquired from also quoted us on the exact same Trane unit and failed to bring this up. In fact, the other companies were going to install a Trane unit on old lines, which would cause early compressor failure and voided the warranty through Trane due to the units being installed on the wrong sized lines in the first place (verified this with Trane). Alex was patient with me through all of my questions, provided examples of what it would look like to replace the lines, and was amazing to work with. Even though we ended up going with a company that made units compatible with our old lines, I am forever grateful to Alex and Ideal Air Conditioning for saving us from dumping a bunch of money to potentially have a premature failure down the road. If replacing the lines was not mandatory, we would have chosen Ideal Air Conditioning in a heartbeat. We plan to use them in the future for all of our HVAC maintenance!
