WHAT OUR CUSTOMERS ARE SAYING ABOUT US

“Shout out to David who came to my house and installed a humidifier. Very knowledgeable man and educated me on things I didn't know. He honored the price that was given to me over the phone for a much more complicated job due to the location of my furnace. Easy to talk to and would highly recommend Comfort Defenders to anybody.”
- David W.

“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.
