HVAC Service Testimonials

Really fair. Really personable. Really reliable and prompt.

Most importantly, they are outstanding HVAC service technicians who diagnose and service problems first time, every time. They also did an outstanding job of installing two new heat pump units at my house. Backed up the installation with outstanding response to a part failure that was under warranty. You won’t lose if you chose these folks for your AC&R needs.

– R. Hooper


Freon Doctor is without a doubt, the best HVAC Service company in Virginia.

I’ve lived in my house for 14 years and have never come close to keeping the upstairs cooled during the Summer. I tried replacing my entire air conditioning unit, put in more insulation in the attic, and finally, had an attic fan installed. Results? Still way too hot. I finally called Doctor Freon. Soto (Owner) came out and assessed my current A/C capability and my needs and provided me with a comprehensive solution to fix my problem. I agreed with his solution and it’s one of the best decisions I have ever made. Now, my entire home (all three floors) stay at the coolness I want and I’m able to enjoy my home again. I highly recommend Doctor Freon and wouldn’t trust my A/C and Heating needs to anyone else. Do your self a favor, next time you need A/C or Heating service, don’t waste time, call Freon Doctor right away.

I must commend Migel and Hugo on their professionalism

in cleaning our ductwork last Thursday, January 9th. They were also very polite and explained what they were doing. I plan on referring your company to my family and friends.

Yesterday, your two men completed the installation of my new furnace.

They worked hard for 8 hours to complete the job and it seems to be working fine. I want to thank you for replacing my 20 year old equipment with a new system….  I’m glad I found a man with character and integrate to deal with.
