In Calverton, many homes are out past the reach of natural gas lines, so propane is a common way to heat. Propane furnaces work much like gas furnaces, but they have their own quirks: tank pressure, regulators, and older units that still use a standing pilot light. When something goes wrong, a technician who understands those details can fix it faster.
Our licensed and insured team makes the trip from Warrenton, about nine miles away, to repair furnaces at farmhouses, rural homes and larger properties. See the full range of our heating services.

Seasonal tune-ups and regular maintenance keep your system efficient, reliable, and ready for summer.
These are the issues we run into most on Calverton service calls:
Calverton is a small rural community in eastern Fauquier County, southeast of Warrenton. Homes, farms and larger properties are spread out, and propane and heat pump systems are common in rural Fauquier homes like these. In many houses, a heat pump handles most of the year while a propane furnace takes over on the coldest nights.
Rural settings bring their own challenges. Dust from fields and gravel drives gets pulled into return vents. Outdoor vent pipes can collect leaves or nesting material. Older farmhouses may have furnaces that have been in place for a long time. And when a Virginia cold snap drops temperatures below freezing for days, a propane system is running hard while your tank level drops. We check the whole picture, not just the furnace cabinet.


Many propane furnace problems come down to a single part, such as a thermocouple, flame sensor or gas valve, and a repair makes good sense. If your furnace is still in solid shape, we will tell you so.
If the furnace is older, uses a standing pilot and needs a costly part, replacement may be the smarter move. A newer furnace with electronic ignition wastes less fuel, which matters when you are paying for propane deliveries. Some Calverton homeowners also pair a heat pump with propane backup to cut fuel use. We install trusted brands such as Rheem, and flexible financing is available.

Calverton homeowners often tell us the hardest part of a breakdown is waiting and wondering. We keep you informed from the first call until your heat is back on.

I met Seth a few years ago when I had another company install a new AC unit improperly. He fixed it and ended up installing a new secondary unit for me a short time later. Ever since then I’ve been a faithful customer and go to Seth for all of our HVAC needs and concerns. I am so thankful to have found a solid company after having countless companies take my money and give me the run around. I cannot recommend Seth or this company enough!! They will take the absolute BEST care of you!!Posted on Google![]()

My heat pump broke in the middle of winter. I called several companies before this one and they all couldn't get to me for a whole month! I called this company and they were able to send someone to take a look at the heat pump the same day. This offered me a lot of relief as I wanted to resolve the broken heat pump as soon as possible so that I didn't have to wear a coat inside my own house or worry about frozen pipes. The technicians were all very respectful of my property and cordial. I ended up getting a new heat pump because we would have had to replace most of the parts of the old one. The price for the new heat pump was fair. Would definitely recommend giving these guys a shot.Posted on Google![]()

On older furnaces with a standing pilot, the most common cause is a worn thermocouple, which senses the flame and keeps the gas valve open. A dirty pilot tube, drafts or low propane pressure can also be to blame. If the pilot will not stay lit after one careful relight, call a technician instead of trying again.
Leave the house right away, do not flip switches or use anything that could spark, and call your propane supplier or 911 from a safe place. Propane has an odor added so leaks can be noticed. Once the leak is handled and it is safe, we can inspect and repair your furnace.
Yes. Propane and heat pump systems are both common in rural Fauquier homes, and many Calverton houses combine them. We repair both sides of these systems and make sure the controls switch to propane heat when the heat pump can no longer keep up on very cold nights.
Calverton is roughly nine miles from our Warrenton base, well within our service area. We regularly work at farms and larger rural properties in eastern Fauquier County. Tell us about gates, long driveways or where the furnace is located, and we will plan the visit so our technician arrives prepared.
A healthy propane flame is mostly blue. Yellow or lazy flames can point to low gas pressure, dirty burners or a problem with combustion air. That can waste fuel and produce more carbon monoxide. Make sure your CO detectors work, and have a technician check the furnace soon.
