WHAT OUR CUSTOMERS ARE SAYING ABOUT US

“Quick and Effective Service:
On one of the hottest days of the year, my AC unit started blowing hot air. David from Comfort Defender came out the same day I called and was quick to assess the problem and repaired it that day. He answered all of my questions and fixed the issue for a fair price. I will use Comfort Defender for future HVAC needs.”
- Robert O.

“Was very satisfied with their service, David arrived thirty minutes earlier than scheduled and diagnosed the issue made the repair and had our A/C back up and running in very short time, also I believe he knew as much about our fruit trees and herbs as we do, that being said what an amazing company and an amazing technician, highly recommend them to anyone who is looking for a reputable and professional company 🙏”

- Jonathan N.

“After return from a lengthy trip, we found our AC unit was not keeping up and the house was getting hotter. As it was one of the hottest days of the year, we didn't have much hope of resolution on a Friday night. We called Comfort Defender in the evening and they arrived in less than an hour to troubleshoot. Found several maintenance items that needed addressing and within an hour had it running efficiently and cooling the house once again. Highly recommend Comfort Defender, their excellent service and knowledge saved us an uncomfortable night or two during a very hot stretch of temperatures.”

- Todd A.
