WHAT OUR CUSTOMERS ARE SAYING ABOUT US

Air Handlers Installation in Fairfax, VA 22032

March 19, 2025

“Comfort Defender LLC save the day and my pocketbook. Bought an older home with underwhelming HVAC and high utility bills. I went through several HVAC service providers for quotes to remedy my home's HVAC issues. Comfort Defenders LLC is by far above the rest. Sadaf is very pleasant, informative, knowledgeable, accommodating, and proactive with her customer service. Sadaf was very proactive following up on the service and flexible on payment terms. Their head consultant and foreman, David was timely, thorough, very informative, knowledgeable, and refreshingly direct and very honest. He did not try to upsell us on anything beyond what we needed. Infact, David seemed to take as much interest in being cost effective, and yet fully functional with our HVAC and water heater upgrades as if it was his own home which we really respect and appreciated. David and his crew work super-efficiently, neatly, tidy and thorough. Pleasantly surprised with both the experience, cost, and outcome. Our home is much more efficient now thanks to Comfort defenders LLC!”

“Year 2025 January
David and Sadaf at my rescue again. Water heater was leaking. It was chilly Sunday morning. I called them in emergency panicking how to stop the water flow. As expected this beautiful couple came to my rescue. They did face time. Guided me on how to stop the flow. Assured me. Next day the crew was home and installed water heater. I can only say God Bless you for your hard work, honesty, professionalism, guidance, and above all the knowledge and assurance you give.
I m lucky to have found this company and they will be my lifetime company to go to for all my HVAc to water heater needs.

Year 2025 February
David figured that my plumbing issues were due to very high water pressure. His crew installed water pressure regulating valve to main pipeline and I couldn’t be more impressed with his work! From start to finish, the crew was professional, efficient, and extremely knowledgeable. They took the time to explain the process and made sure everything was done to the highest standard. They secured the pipes as well with wall which was not done by original builder. The installation was seamless, and my water pressure has been perfect ever since. I highly recommend.

Year 2023: It was very reassuring to have a skilled, pleasant technician like David to come within minutes after my condensation pan got filled with water. Right from customer service and her pleasant reassuring way to giving an immediate appointment on Saturday ( hottest day with 95 degree f temp, David arrived at 8:15pm few minutes after placing a call.
He diagnosed the issue in minutes. Honest to the core! Super skilled, knowledgeable, technical and great demeanor. Helped me uncover a mystery surrounding a pipe leak near AC and guided next steps to resolve the pipe issue. They are my go to company now. I recommended them to all my friends.”

“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.”
