HVAC Unlimited in Lorton gas furnaces, electric furnaces, and oil furnaces from the trusted brand Carrier:

  • Gas furnace: Gas furnaces are more efficient than oil furnaces, but are usually slightly more of an upfront investment. The fuel typically costs less, but you need to be in an area that has fuel readily available. While gas furnaces are quieter and cleaner, they provide less heat per BTU.
  • Oil furnace: Oil furnaces typically cost less that gas furnaces, but their fuel is usually a little pricier. You get higher BTUs—which means more heat—than gas, but maintenance is more extensive. More residents in the Virginia areas use gas furnaces, but if you have an older house you might have inherited an oil unit.
  • Electric furnace: Electric furnaces use electricity to heat your home, which means no fuel costs and open flames in your home. They are typically more expensive that fueled furnaces, but are more durable, last longer, and don’t emit carbon dioxide. They are also quicker to be installed.

HVAC Service Call

I highly recommend this company for your HVAC needs! What a tremendous effort by the HVAC Unlimited Team supporting our requirements. I called several other companies who either did not return my call or had excessive emergency rates. The HVAC Unlimited Team was timely, professional, and provided exceptional customer service. The HVAC representative (Jeremy G.) was a total pro -- he kept me informed on his arrival time, provided detailed analysis of the diagnosis, and walked me through the process of bringing my HVAC back to a fully mission capable state. Further, Jeremy was very patient and answered the plethora of questions I had regarding my system and provided information on routine service opportunities that the company can provide. If you are in need of HVAC support, don't hesitate any further, call this team and you will be in good hands.

Great Customer Service

I chose HVAC Unlimited due to the numerous good reviews, and I was very pleased with Jermaine, the technician, who came out to look at my systems. He thoroughly answered all my questions, was patient, as he looked at my second system, which wasn’t on the original request, and gave me confidence that the minor repairs suggested were warranted. Having had a previous unsatisfactory experience with another company, I was much happier with this one.

Job Complete!

I have used HVAC unlimited for approximately 3 years. Mostly routine service but sometimes for a repair. I have been satisfied with their work each and every time. The parts came in over the weekend and were installed earlier today. Thanks Jermaine!
