Jermaine Allen was courteous, efficient and knowledgeable.

John – Herndon, VA

A call was placed to the HVAC answering service the previous night. We were asked if we required a call back that evening but declined as felt we could manage till morning. At 7:30 am the following day (Wednesday, 27 December) We got a call from Cindy who said our tech would be on site between 1000 and noon. We received a call around 930 from Jermaine who said he would be on site at 1000 am. He arrived at 1000am on the dot and immediately started diagnosing the issue. He quickly found the problem and got the Heat pump blower motor running again very quickly. He provided some valuable insights on our TRANE unit and the repair that was being done. He documented his work and answered all the questions that we had about our system. Both my wife and I found Jermaine friendly, knowledgeable, and courteous. We both commented that from a service call perspective (any type of service) this is one of the best ones we’ve ever experienced. In the future, for any additional service work we plan on asking for Jermaine personally and would recommend HVAC and Jermaine to anyone in the neighborhood that requires Heating and A/C service. He did a fantastic job and my made a great impression on both my wife and I. Thanks again for the great work Jermaine!

I switched to HVAC Unlimited after an unfortunate experience with another HVAC company. I am now receiving professional and courteous service from an honest company that does not try to “up sell” with every visit. Jeremy is the best technician ever. Thank you!

I was told by a different HVAC Co, that my HVAC unit “would not last the summer”. Recommended replacing entire unit & furnace. A friend recommended HVAC Unlimited. They came, did a thorough review of my HVAC units and solved the problem for less than $300. Integrity & professionalism – what more can I say!

Dennis – Herndon, VA

Their tech ned was in, analyzed situation, repaired the bad part, and was off. No issues.

Donato M – Herndon, VA

First of all, I called and got an appointment for the same day, later in the afternoon. Ned came out to assess both of our units. He spent a lot of time with me explaining the issues, and he really knows what he’s talking about. Ned didn’t pressure me into anything, and explained all the options with respect to pricing. He is a consummate professional and I’m happy to have found HVAC Unlimited.

Oress – Herndon, VA

Nancy – Herndon, VA

We were introduced to HVAC Unlimited 8 years ago and remain very pleased with their served. After installing a heat pump 8 years ago, our all electric home and our all electric rental home have been maintained by this company. The change in our electric bills was immediately reduced out heating and AC bills. We are now pleased that they recently they can provide plumbing service, even the small things like toilets and faucets. You can be sure we will call them first of this.

Mike – Herndon, VA
