What People Are Saying About Us

Kelsey Smith
★★★★★
Derek was outstanding to work with. He not only answered on a Saturday night, he was out to my house on Sunday morning when he said he’d be there. Professional, reliable, hardworking, and honest, what more can you ask for? We really appreciate his work and will recommend him and use his services again in the future.
Matthew Richards
★★★★★
We had a complete HVAC failure on a Monday Morning, and Derek was able to come out within a couple of hours to troubleshoot and help us. Ultimately, we needed a new unit, which Derek was able to source, deliver and install within 48 hours. The communication, workmanship and response were all beyond A+! I strongly recommend using Derek and Qualified Comfort whenever possible!

Mr. Derek was very nice and friendly; very accurate, when he said that he would be here within an hour. He did arrived on time and really knew what the problem was. We will definitely recommend him to family and friends. We will be expecting his future services, again. Thank you very much for a JOB WELL DONE!

Qualified is the best!! Only local HVAC company we'll use. Came out the next day when our home warranty company couldn't find anyone to fix our thermostat and even called to let us know he was running late. Diagnosed and fixed the problem quickly and then worked patiently with my warranty company to try to get me paid (they wasted 45 minutes of his time). Again, we won't use anyone else.

★★★★★
I highly recommend this company. To anyone in the Sierra Vista, Huachuca City, and Hereford areas. Derek is highly knowledgeable and fast and efficient for diagnostics of repairs needed for your HVAC systems, we had a previous company do work on our property that didn't do a good job. Derek and his team figured out exactly what the issues were with our system and got us a replacement Condenser unit for our home as our old one was well over due for replacement. They did a fantastic job with professional installation of the unit and replacement of our thermal expansion valve as well. They were tidy and efficient. Highly recommend them to service any job you happen to have gone wrong and reasonably priced services.

★★★★★
After 28 years we needed our first furnace repair. Saw Qualitys 5 stars and made the call. We are so happy we did. They were at our house within hours even though it was not an emergency. Derek and Shaun spent 5 hours over two days to try to avoid us having to get a new furnace or motherboard. Both very expensive. They found it was a loose wire on motherboard and sottered it. Works great at very minimal cost. We would highly recommend

★★★★★
Awesome! My AC failed in the summer heat but Derek helped trouble shoot over the phone and offered quotes for possible repairs. He came the same day, as requested, and had the necessary part in his truck so the service took less than an hour. I highly recommend them.

★★★★★
Temperatures were rising and one of our A/C units stopped working. Called Quality Comfort and chatted with Derek Coleman who promised to come out the next day at 7:30AM. Derek was punctual, professional, and provided expert service at a great value. He needed to leave to get the part needed but was back shortly and got the job done just like that! Advice was provided as to how to keep the units in good order. Derek certainly knows his stuff and I highly recommend his services as you won't find anyone better out there.
