“Last December the boiler in my rental went bad Idid not know that Dave worked on boilers and I asked him if he knew anybody that did and he said that he did, I had Dave help me with my ductless system a couple years ago and he did a great job. So I had Dave look at the boiler that was broken in my rental property, Dave looked at it and gave me an estimate for the new boiler and I agreed to it, Dave and his team replaced it all in ONE DAY. I left work early and was able to see him finish up the install and it looked great, nice and clean, He did an outstanding job and it was so fast it just blew me away. I can’t express how impressive and professional he and his team are, I was so impressed and thankful to him for his outstanding and quality work I couldn’t say thank you enough. Thanks Dave.”

“Highly Recommend!!!! We had the best experience with Comfort Defender installing our Trane HVAC system. Our daughter has severe allergies to dust mites and pet dander, David also installed an air purifier and humidifier and this helped eliminate the allergens in our home by 90%. We have also used them for whole house water filtration and water softening system to our home. David is a top notch professional, courteous and extremely knowledgeable in his field. I highly recommend them as they are experts in all aspects of HVAC.

We have also used him for installation of Trane unit with air purification system to our Business in Fairfax, the company is well versed in both residential hvac and commercial hvac. Top notch professionals!”

Comfort Defender was great! My AC stopped and they were able to get to my house quickly to check it out. The tech did a good job explaining the issue and got everything tuned-up.
