Calverton is a small rural community in eastern Fauquier County, southeast of Warrenton. It is roughly nine miles from our shop, and we make the drive often. Homes here range from farmhouses to newer houses on larger properties, and each one depends on a system that can handle cold nights and sticky summers.
Our licensed and insured technicians handle complete HVAC service, with a focus on the equipment rural homes use most.
Your safety and comfort come first. Our team is fully insured and trained to handle all AC services with precision.
We use only trusted brands like Rheem to ensure long-lasting performance and energy efficiency.
From 10% discounts for veterans and seniors to flexible financing plans, we make cool comfort affordable.
Seasonal tune-ups and regular maintenance keep your system efficient, reliable, and ready for summer.
We also offer system replacement, indoor air quality options and maintenance plans.
Calverton is made up of rural homes, farms and larger properties. Without natural gas lines in many rural areas, propane and heat pump systems are common in Fauquier homes like these. Some homes use both, with a heat pump for mild weather and a propane furnace for the coldest nights.
Open fields bring dust and pollen that load up filters and outdoor coils. Wind across open land can make cold nights feel even colder inside a drafty older farmhouse. We keep these conditions in mind on every visit.


If you heat with propane, check your tank level before cold weather and keep an eye on it during long freezes. Running out can put out a pilot and may require a system check before the furnace restarts.
Keep grass, weeds and brush trimmed back from your heat pump or AC unit. After harvest or mowing season, check your filter, since field dust can clog it fast. Book heating maintenance in early fall and cooling maintenance in spring.

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![]()

Yes. Calverton is about nine miles southeast of our Warrenton shop, and we serve homes and farm properties throughout the area. Same-day service is often available. When you call, let us know about any gates, long driveways or directions we will need so our technician can find you easily.
It depends on your home. Heat pumps are efficient in mild weather and also provide cooling, which is why they are common in rural Fauquier homes. Some homeowners keep propane as backup heat for the coldest nights. We can walk you through the pros and cons of each setup for your house.
When the tank runs out, the furnace shuts down, and on some systems the pilot goes out. After a refill, the lines and appliances may need to be checked for leaks and relit safely. Your propane supplier or a licensed technician should handle the restart. Keeping an eye on your tank helps avoid this.
Signs of a poorly sized system include short run times, rooms that never get comfortable, high humidity in summer and a system that runs nonstop. Farmhouses that have been added onto over the years are especially prone to this. We can check your home and equipment and tell you what we find.
It can. Dust and pollen from open fields clog filters and coat outdoor coils, which cuts airflow and efficiency. In Calverton and other rural areas, checking the filter more often and keeping the outdoor unit clean helps a lot. An indoor air quality upgrade can also help if dust inside the home is a concern.
Calverton is part of our Warrenton service area. We also serve nearby Catlett, Midland, Bealeton. See every community on our service areas page.
