Mr. Germaine Allen was exceptional at explaining everything and showing me what was wrong with our HVAC. He was patient and speedy and very clean. He told me about renewing our service plan, which I did because of his recommendation. He explained what filters I should use and when I should call back for service.

I had the original contractor out to repair our brand new system 3 times in the 7 years since they installed our system. They never found or fixed the problem. This morning Jeremy identified the problem immediately and fixed and cleaned our system. All is working well now. Highly recommended.

We have been HVAC Unlimited customers for three years. The service is always top notch. The providers are professional, polite, and listen to any concerns we have regarding our HVAC unit. Jeremy, who completed our cooling inspection today was no exception. Keep up the great work!

Great job!
Jermaine was very professional and easy to work with. He completed the servicing on my HVAC unit in a timely and efficient manner and answered all of my questions. The only complaint I have about HVAC Unlimited are the four hour service windows. That's too long to be stuck waiting at home for a technician to come.

I have been a client for 9 years. HVAC is responsive and charges very reasonable rates. They recently replaced my water heater. Randy was efficient, good humored, honest and kept my apartment spotless.

Install new Carrier Infinity system to replace the 18 year old York system completed and is running great. Nice installs resolved a lot of issue besides replacing the old system, including separated flue, poorly installed water heater drain, poorly setup return system and leaking duck work in attic.
James Dillon - Reston, VA
Jeremy was the first to call me back after making multiple inquiries to different business. He was able to arrive and diagnose the issue with our AC unit in under an hour. He was very knowledgeable and was able to give multiple options for a solution. Would absolutely recommend to anyone who needs HVAC work!

Derik - Reston, VA
My wife and I have been HVAC Unlimited customers for over a year and are very pleased with the quality of service they provide. We first called them based on a family recommendation. Another local company made a service call and claimed a major component of our HVAC unit needed to be replaced, at a cost of $2500. Ned came out from HVAC Unlimited, diagnosed the appropriate problem - that the unit needed to be cleaned. He cleaned it on site and our unit has worked better than ever, for less than 10% of the original quote from the other company. Great company with excellent service. Highly recommend them.

Rony was great. I became a fan of your technicians when you replaced our furnace in January. And today's was no surprise to me. Showed up when you said you were, and gave me piece of mind on the quality of AC for this hot summer. Thanks!
