Fairfax air conditioning: added later in the City, original out in Fair Lakes.
Inside the City of Fairfax the typical owner’s house went up in 1966, and about 7 in 10 were built before 1980. Plenty of those got central air years after they were built, pushed through ductwork laid out for a furnace, with a return that’s often smaller than the air conditioner wants. So a Fairfax tune-up starts inside, at the filter and the airflow, before anybody looks at the outdoor unit. A starved coil runs too cold, frosts over and quits on the hottest afternoon of the year.
Past the city line the houses get younger. Fair Lakes and Navy went up mostly in the late 1990s and 2000s, and in Fair Lakes about a third of the homes are townhouses, so the condensers stand in a row out back a few feet apart, collecting the same leaves and grass clippings every season. Some are still the units the builder set, past twenty-five summers now, and the coil cleaning is the part of the visit that earns its keep there.
Kings Park West is the heat pump corner of the Fairfax address. Close to half its homeowners heat with electricity, and in a 1970s house there that usually means one outdoor unit doing the cooling all summer and the heating all winter. The spring visit is the cooling side; the heating side gets its own visit in the fall.
Fair Oaks and Merrifield are mostly condo and apartment buildings. There the air handler or fan coil sits in a hall closet, the outdoor unit is on a roof or a shared pad, and the drain line from the coil runs over somebody else’s ceiling. Of everything on the list, that drain line is the one condo owners in Fairfax should never let go a year.

- Central air in houses this old was usually added later, and a small return is the first thing to check.

What an AC tune-up costs in Fairfax.
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 Fairfax.
Ice on the copper line in July
If the larger copper pipe at the outdoor unit is frosted on a hot day, the coil inside is running too cold. In an older Fairfax house with a small return, a clogged filter is the first suspect. Switch the cooling off, let it thaw, change the filter, and book the tune-up before running it hard again.
The house is older than its AC
Central air in an older house was usually added later, often with a return too small for it. Checking the filter and the airflow in spring is how you keep the coil from icing up in July.
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 Fairfax.
Questions to ask anybody who books you, us included.
Will they check the return, not just the outdoor unit?
In a house that got central air after it was built, the return air path decides how well the whole system cools. Ask whether the tech looks at the filter size and the airflow inside before calling the job done outside.
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.
I would gladly recommend them to anyone in the greater Fairfax/Alexandria area without reservation.
Swiftpro came out the same day I called when my AC was out and had it fixed in less than an hour after arriving.
Mr. Moises Rojas was great! A very experienced HVAC technician who carefully examined our very old AC system, and helped guide us through options for our original AC system. Highly recommended!

AC tune-up questions from Fairfax.
My Fairfax condo’s AC drips into the unit below. Is that a tune-up problem?
Usually it’s the condensate drain: the line or the pan under the coil is clogged, and the water finds another way out. Clearing the drain line is part of every tune-up, and a clogged one found in April costs a lot less than a neighbor’s ceiling in August.
How do I tell if my Fairfax house has two systems?
Count the outdoor units and the thermostats. Two of each usually means two systems, often one for the main floors and one for the bedrooms, and each gets its own tune-up at $69. Bigger single-family houses, like many in Braddock and Fairfax Station, are the likeliest to have two.
How much is an AC tune-up in Fairfax?
$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.
