New Baltimore is an unincorporated community in northern Fauquier County, along the US-29 corridor between Warrenton and Gainesville. It is only about five miles from our Warrenton base, which makes it one of the closest places we serve.
Homeowners here call us for everything from a furnace that will not light to an AC that cannot keep up in August. We handle the full list of heating and cooling services, and we explain your options in plain language before any work begins.
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.
Our technicians cover the heating and cooling needs of a typical New Baltimore home:
New Baltimore is mostly single-family homes, and many sit on larger lots. Larger houses often mean longer duct runs and more rooms for one system to reach, so airflow and blower performance matter a lot here. A system that is a little undersized or has leaky ducts can leave far bedrooms uncomfortable.
Being close to Vint Hill and the open land of northern Fauquier, many homes are exposed to wind and full sun. Humid summers keep AC systems running long hours, and cold winter nights push furnaces and heat pumps hard.


In larger homes, filters load up faster because more air moves through them. Check yours monthly during peak seasons. Before heating season, book a furnace or heat pump tune-up. Before summer, have your AC coil and refrigerant checked.
Walk around your outdoor unit a few times a year and clear away grass clippings, leaves and branches. If some rooms always feel off, mention it at your next visit so we can check the ductwork.

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![]()

Uneven rooms are common in larger single-family homes like many in New Baltimore. Long duct runs, leaky joints, closed vents and a dirty filter can all cut airflow to far rooms. Sometimes the system is simply undersized for the house. We can check airflow and ducts to find the cause.
Size depends on more than square footage. Insulation, windows, sun exposure, ceiling height and ductwork all play a part. A system that is too big short cycles and struggles with humidity, while one that is too small runs nonstop. We measure your home before recommending any new equipment.
With regular maintenance, most furnaces and air conditioners last many years, but lifespan varies with usage, installation quality and care. Heavy summer use and skipped tune-ups shorten it. If your system needs frequent repairs or your energy bills keep rising, it may be time to compare repair and replacement costs.
They can. Better filtration, air purifiers and humidity control can cut dust, pollen and stuffiness, which helps if anyone in your home has allergies. With open land around New Baltimore, seasonal pollen can be heavy. We can look at your home and suggest options that fit your system.
