A summer in The Plains: 90 degree afternoons, then the storms that take trees down.
NOAA’s 1991 to 2020 normals for the Warrenton 3 SE station, the nearest long temperature record, about 12 miles south, put the average July high near 85 and count about 21 days a year at 90 or hotter. In July 2019 the heat index across Northern Fauquier passed 110. Those are the afternoons a weak capacitor or a dusty coil finally quits; a spring tune-up finds either one in April.
Across 20198 about six owner homes in ten heat with electricity, usually a heat pump, so the unit facing July already got the house through roughly 98 freezing nights. About one in five heat with propane, and there the cooling is its own outdoor unit sharing the furnace’s blower. Same $69 a system either way.
Then come the storms. NOAA’s storm records list numerous trees down in The Plains on July 12, 2022, Bunker Hill Road among them; dozens of trees and wires down along Halfway Road and The Plains Road in 65 knot gusts on August 7, 2023; more on that road on August 3, 2024; and trees down south of town by Old Tavern Road on July 16, 2025. Four summers running. A big tree near the house puts the outdoor unit within reach of a limb.
After a storm, walk out before you count on it. Look for limbs on the cabinet, flattened fins, the unit shoved off level on its pad, and the disconnect box beside it. If the power went out, give the system a few minutes once it’s back; if it won’t start, reset its breaker once and leave it. FEMA maps a flood zone a few hundred yards from the center of town, and a 2017 flash flood closed Old Tavern Road half a mile out: if water reached the unit, keep it off. Then call us after a storm and we’ll check it all.
The Plains houses, by the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
The Fauquier County side
ZIP 20198 as a whole, the Town included: its own homes are too few for steady Census figures.
- Median home built1983 Census
- Built before 1980about 5 in 10 Census
- Built since 2000about 3 in 10 Census
- Most homes aresingle-family houses, about 9 in 10 Census
- Heated withelectricity, about 6 in 10 Census
- Rentedabout 3 in 10 Census
- Electric heat here usually means a heat pump, so the outdoor unit runs in both seasons and its spring visit counts for the winter too.
What an AC tune-up costs in The Plains.
One price per system, $69, regularly $99. We go through it before a Northern Virginia July finds the weak part for you. Anything it turns up is priced in writing before any work, and if it can wait, we say so.
- AC tune-up, one system$69, regularly $99
- Furnace tune-up, one system$69, regularly $99
- Heat pump, boiler or ductless mini split tune-up, one system$69, regularly $99
- Comfort+ membership, a cooling maintenance visit every spring included$199 a year
A house with two systems books two tune-ups, one for each, and a heat pump or a ductless mini split is the same $69 a system. The heating side, a furnace or a boiler, gets its own tune-up in the fall at the same price.
With Comfort+ membership at $199 a year, the cooling maintenance visit comes every spring, along with a heating maintenance visit, a water heater flush with a sewer camera inspection and a dryer vent cleaning.
When an AC tune-up is worth booking in The Plains.
It hums but won’t start after the power comes back
Storm power that flickers on and off is hard on an outdoor unit’s capacitor and contactor. If the fan won’t spin or the unit hums without starting, switch the cooling off at the thermostat and call. Left trying, it can take the compressor with it.
A heat pump works both seasons
It cools all summer and heats all winter, so it piles up more hours in a year than an air conditioner that sits idle from October to May.
Before the first hot week
A weak capacitor is a small fix on a mild day in April. Found by a July heat wave, it’s a house with no cooling.
How to pick the best AC tune-up company in The Plains.
Questions to ask anybody who books you, us included.
Will they test the electrical parts, not just rinse the coil?
Where storms have put trees and wires down four summers running, the capacitor and contactor take the beating. Ask whether the tech tests them and writes down the readings.
What does the price cover, and is it per system?
Ask what gets cleaned and what gets checked, and whether a second system costs extra. A number with no list behind it is hard to hold anybody to.
Do they write down what they found?
Ask for the findings in writing, with a price on anything that needs fixing and an honest word on what can wait. A tune-up you never see written down is one you take on faith.
Do they find the leak before they sell refrigerant?
An air conditioner doesn’t use up refrigerant. Low means it’s leaking somewhere, and a company that tops it up every spring is selling you the same refrigerant twice.
What our customers say.
Quick response, Elvis was knocking my door in a couple of hours after my call to the office. He did full inspection for both HVAC units, and answered all my questions. Both systems are working well. I always have very pleasant experience with SwiftPro

AC tune-up questions from The Plains.
A branch hit my outdoor unit. Is that a tune-up?
If it still runs, yes: the tune-up looks over the whole system, cabinet and coil included, and anything bent gets a written price first. If it won’t run at all, say so when you call; that’s a repair visit.
Is April too early for an AC tune-up out here?
No. The Warrenton station’s normals put the last spring freeze around April 9, so by late April a heat pump is mostly done heating and the cooling side can run for real, with May and June left to fix what turns up.
How much is an AC tune-up in The Plains?
$69 per system, regularly $99, the same for a central air conditioner, a heat pump or a ductless mini split. A house with two systems books two. If the tune-up turns up a repair, you get its price in writing before any work, and you decide.
How often should an AC get a tune-up?
Once a year, in the spring, before the first heat wave. The heating side gets its own visit in the fall. The filter needs attention more often, every one to three months, and it’s the cheapest thing on the list.
