Fins pressed flat after a hailstorm
Shine a flashlight across the outdoor coil. Fins bent flat by hail or matted with grass block the air it needs. The tune-up cleans the coil and tells you straight whether the damage is past what a cleaning fixes.

What it costs
What an AC tune-up costs in Round Hill.
One price per system, $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
$99
Furnace tune-up, one system
$99
Heat pump, boiler or ductless mini split tune-up, one system
$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 $99 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.
What’s different in Round Hill
Round Hill’s outdoor units cool through 30 days of 90 degrees, then heat all winter.
Round Hill got its start as a way out of the heat: the Virginia Department of Historic Resources calls it a vacation spot for people escaping Washington’s sweltering summers. It still gets hot here. At the Purcellville weather station, about three miles east-northeast, July afternoons average 86.4 degrees and about 30 days a year reach 90 or more. On July 28, 2023, mesonet stations across western Loudoun read heat indices over 110.
What cools a Round Hill house usually heats it too: 1,257 of the 2,362 owner homes in 20141 heat with electricity, which out here usually means a heat pump. The station counts close to five times as much heating weather as cooling, 4,942 heating degree days to 1,050, so the spring visit is the first close look at a machine coming off its harder season. The coil that frosted and thawed all winter gets cleaned, and the drain line gets cleared before summer fills it.
Storms find the outdoor unit first. Quarter-size hail fell in Round Hill on July 25, 2023, and on June 16, 2016 winds estimated at 61 knots uprooted large trees along New Cut Road, Bell Road and Main Street. After a storm like that, walk out and look: limbs or leaves against the coil, a dented cabinet, a pad knocked off level, wiring pulled loose. If you see any of it, leave the cooling off and call us to check it all before it runs.
Flash floods are the other Round Hill storm. Torrential rain closed Main Street at Greenwood Drive in July 2017, and on May 5, 2025 the Blue Ridge Volunteer Fire Department reported water over several roads north of town and several flooded basements. If water reached the air handler or the outdoor unit, keep the system off and call us. We check the motor, the controls and the wiring before it runs again.

- 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.

When to book it
When an AC tune-up is worth booking in Round Hill.
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.
It’s still the original system
A house from the 2000s often runs its first air conditioner, now 15 to 25 years old. A yearly look tells you how much life it has left before a hot week does.

Questions to ask anybody who books you, us included.
Will they note storm damage apart from wear?
If hail or a falling limb hit the unit, ask for that damage written up on its own, separate from normal age. It keeps the record clear for an insurance claim later.
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.

Questions
AC tune-up questions from Round Hill.
When should a Round Hill AC tune-up be booked?
Late April or May. In half of all years the last spring freeze at the Purcellville station has come by April 16, and a visit soon after catches what the winter did to a heat pump before the first 90 degree week.
Our early 2000s Round Hill house still has its first outdoor unit. Worth a tune-up?
Yes. The median owner home in 20141 dates from 2004, so plenty of units here have 20 summers on them. At that age the write-up is the point: what’s wearing, what can wait, and whether to start planning a replacement.
How much is an AC tune-up in Round Hill?
$99 per system, 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.
