Why Centreville Homeowners Choose Fireside Heating & Air Co.
Centreville’s housing story is unusual, and that matters when you’re choosing an HVAC company. The bulk of this community was built between 1985 and 1998, driven by the Route 28 and Dulles tech-corridor expansion. That means thousands of homes, especially in Sully Station and the South Centreville townhome clusters off Centreville Road, are running original or second-generation heat pumps that are now 25 to 40 years old. We’ve replaced systems in the same Bull Run area cul-de-sac three times in one season because the neighbors talked.
Our technicians are trained as journeymen, background-checked, and uniformed. They put on shoe covers without being asked. They carry parts for Carrier, Trane, Bryant, and American Standard on the truck, which is why most jobs finish in one visit. Our home office is staffed by live people, never a voicemail tree, 24 hours a day, every day of the year. The price we quote is the price you pay. And everything we do is backed by our 90-Day Done Right Promise, in writing, with no paperwork to file and no argument if something needs adjustment.
We are not the cheapest bid in Fairfax County. We are the bid you make once.
HVAC Services We Offer in Centreville
AC Repair & Installation in Centreville
Summer humidity in Centreville pushes heat index readings above 100°F for weeks at a stretch. When your system cannot keep up, we diagnose whether it is a refrigerant issue, a failed compressor, or the legacy undersizing problem common to 1989-1995 townhome construction off Route 28. If replacement makes more sense, we size it properly and install it right. Learn more about our AC Repair & Installation in Centreville.
Heating & Furnace in Centreville
Gas furnaces in the colonial-style single-family homes near the 20122 zip code see hard winters. Heat strips in aging townhome heat pumps fail when auxiliary heat is called. We repair both, and we will tell you straight when a furnace replacement is the smarter spend. Learn more about our Heating & Furnace in Centreville.
Heat Pump & Mini Split in Centreville
This is our most called-for service in Centreville, and for good reason. The original heat pumps in this market are dropping in waves. Many still run on R-22 refrigerant, which is no longer manufactured. We replace with properly sized modern systems and install ductless mini-splits where the original flex ductwork has collapsed in tight utility closets. Learn more about our Heat Pump & Mini Split in Centreville.
Air Quality & Ventilation in Centreville
Aged flex ductwork in Centreville’s stacked townhomes leaks conditioned air into wall cavities and pulls attic dust into supply lines. We inspect, seal, and recommend Air Quality & Ventilation - Centreville upgrades based on what we find in your specific mechanical closet configuration.

Why Centreville’s Climate & Housing Affect HVAC
Centreville sits in the Virginia Piedmont, far enough inland that winter cold snaps regularly plunge below 25°F. That threshold matters because it is exactly where air-source heat pump efficiency falls off a cliff. The aging systems installed during the 1985-1998 build-out were never designed for that load. Their auxiliary heat strips, now corroded after decades of intermittent use, fail precisely when they are needed most. We see this pattern every January in the Sully Station and South Centreville townhome communities.
Summer is the mirror problem. Sustained high-humidity heat, with heat index readings parked above 100°F for weeks, punishes systems that were manually sized on the light side during the permit boom. Technicians working the Centreville Road and Route 28 corridors routinely discover original builder-grade heat pumps spec’d one tonnage size too small for actual square footage. The homeowner thinks the system needs refrigerant. It does not. It needs proper sizing, which means straight talk about repair versus replace. We give that talk. Then we do the job right, or we make it right.

FAQs About HVAC in Centreville
In Centreville, replacing an aging heat pump typically runs $4,800 to $8,500, depending on tonnage, access constraints in your mechanical closet, and whether the original flex ductwork needs replacement. Townhomes in Sully Station and South Centreville often run toward the higher end because of tight access and collapsed duct sections. Call (866) 561-3358 for a free, exact quote on your specific system.
Your heat pump was likely installed during the 1985-1998 build boom and was sized for moderate Northern Virginia winters, not the Piedmont cold snaps that regularly drop below 25°F. At that temperature, the system calls for auxiliary heat strips that may have failed from decades of disuse. We test the strips, inspect the refrigerant charge, and tell you whether repair or replacement is the better spend.
For most Centreville homeowners with original 1990s systems, replacement is the smarter money. R-22 refrigerant is no longer manufactured, parts are scarce, and the original units were often undersized by one ton. We will give you straight talk on repair versus replace, with written pricing for both. If replacement is right, we size it properly and back it with our 90-Day Done Right Promise.

What Centreville Customers Say
"System is running well again and the price was in line with the other quote I got. The arrival window was four hours wide and he came at the very end of it, so plan your day around that."
- Simone Dawson"The drain line was clogged and the safety switch had shut the whole system down. He cleared it, flushed it, and fitted a proper cleanout so I can pour vinegar through it myself once a season."
- Terrence Coleman"The work was done properly. I did have to follow up twice to get the invoice and the warranty details emailed over. The repair itself has been trouble free."
