One HVAC Team for Four Local Service Areas

We organize our service area around four hubs so you get a technician who knows your part of Virginia. Each hub has its own page with local details, and every town under it has pages for furnace repair, furnace maintenance and more.

In every hub, you get the same approach: a licensed and insured technician, a clear explanation of the problem, and upfront, transparent pricing before work starts. See everything we do on our HVAC services page.

Fully Insured

Your safety and comfort come first. Our team is fully insured and trained to handle all AC services with precision.

Quality Materials

We use only trusted brands like Rheem to ensure long-lasting performance and energy efficiency.

Reasonable Price

From 10% discounts for veterans and seniors to flexible financing plans, we make cool comfort affordable.

Quality Maintenance

Seasonal tune-ups and regular maintenance keep your system efficient, reliable, and ready for summer.

The Towns and Communities We Serve

Here is how our service area breaks down by hub:

Warrenton area: our home base in Fauquier County, along with New Baltimore, Calverton, Midland, Bealeton, Catlett, Marshall and Remington.
Gainesville area: western Prince William County, including Haymarket, Bristow and Nokesville.
Partlow area: the rural communities of southern Spotsylvania County and nearby Caroline County, including Lake Land’Or.
Fredericksburg area: the city of Fredericksburg and Spotsylvania Courthouse.

Don’t see your town? Call us anyway.

How Homes Differ from One Hub to the Next

The homes we work on change as you move across the region. Old Town Warrenton has many older homes, while farms around Fauquier County often rely on oil, propane or heat pumps. Around Gainesville, newer subdivisions and townhomes are common, and larger houses often have multi-zone systems.

In the Partlow area, wooded rural homes lean on heat pumps and propane furnaces, and Lake Land’Or adds vacation homes that may sit empty part of the year. Fredericksburg’s historic downtown has older homes with older ductwork, while Spotsylvania Courthouse blends rural homes with newer subdivisions. Across all of it, humid summers and freezing winter nights test every system.

How Service Works in Every Area

Reach out: tell us your town, your system type and what you are noticing.
Get scheduled: we set a time that works for you, and same-day visits are often possible.
Diagnosis: your technician inspects the system and finds the cause, not just the symptom.
Clear options: you get upfront pricing before any work begins.
The fix: we complete the repair or service and test the system before we leave.

Seasonal HVAC Care Across the Region

A little routine care helps your system in any part of our service area:

Book a furnace or heat pump tune-up in early fall, before the first freezing night.
Have your air conditioner checked in spring, before humid weather sets in.
Change your air filter regularly, and more often if you have pets or live near farmland.
Have a seasonal home’s system checked before you start using it again.

A preventative maintenance plan makes it easy to stay on schedule.

 Trustindex verifies that the original source of the review is Google. 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!!

 Trustindex verifies that the original source of the review is 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.

Service Area FAQs

Which areas does Service First Heating & Air serve?

We serve four hub areas: Warrenton and nearby Fauquier County towns, Gainesville and western Prince William County, Partlow and the surrounding parts of southern Spotsylvania and Caroline counties, and the Fredericksburg area, including Spotsylvania Courthouse. Each hub page lists the towns we cover.

Where is Service First based?

Our company is based in Warrenton, in Fauquier County. From there, our technicians travel to homes and light commercial buildings across all four of our service areas. If you are not sure whether your address falls inside our area, give us a call and we will let you know right away.

Do you work on rural homes with propane or oil heat?

Yes. Many homes in rural Fauquier, Prince William and Spotsylvania counties heat with propane, oil or heat pumps, and our technicians work on these systems every heating season. We also service gas furnaces, air conditioners and the ductwork that connects everything. Let us know your fuel type when you call so we can prepare for your visit.

Is same-day service available in every area?

Same-day service is often available across all four hubs, though it depends on the day’s schedule and when you call. During the first cold snap of winter or a summer heat wave, calls pick up quickly, so it helps to reach out as soon as you notice a problem. We will always give you a straight answer on timing.

Do you offer discounts or financing?

Yes. We offer a 10 percent discount for veterans and seniors in every town we serve. If you need a new furnace, heat pump or air conditioner, flexible financing is available to help spread out the cost. Our pricing is always upfront, so you will know what the work costs before we start.
