Price in writing firstYou see every option priced before anything is ordered
What it costs
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 Waterford
About a quarter of owner homes in ZIP 20197 were built before 1960, while the median owner home dates to 1996. This mix means some air conditioners have decades of wear, while others are still in their prime. Since 98 percent of housing is detached, your AC is likely a standard split system with an outdoor condenser and an indoor air handler. On an older unit, the visit focuses on the parts that wear: the fan motor, the capacitor, and the contactor. On a newer unit, it is mostly about cleaning the coil and clearing the drain line.
Waterford homes rely on private wells for drinking water. The county’s water feasibility study notes that treating the groundwater for iron and manganese is likely needed. These minerals can affect your AC system, especially if your home uses a heat pump or has a dehumidifier. Iron and manganese can clog filters or coat coils over time. A tune-up includes checking the air filter and the coil for any buildup. If you see rust-colored water or scale, that is a sign your well water is affecting your system, and a flush or filter change may help.
The village sits in the Catoctin Valley, and some parcels lie within the 100-year floodplain. If your AC condenser or air handler is in a basement or low area near the creek, check its elevation relative to past flood levels. In 2020, South Fork Catoctin Creek rose to 11.11 feet, and water came up to a building on Main Street. An AC unit that sat in floodwater needs a thorough check before it runs again. Moisture can corrode electrical components or clog the drain line, so a tune-up after a flood is a good idea.
Loudoun County’s Waterford Historic District covers the central village. Most exterior changes there need the County Historic District Review Committee’s approval before work starts. If your AC condenser is on a visible wall or in a prominent spot in the district, and you need to move or replace it, that is an exterior change. Cleaning the coil or clearing the drain line does not require that review, but swapping the condenser unit might. Check with the committee before any major changes to avoid delays.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
ZIP 20197 as a whole: every Waterford address, the village included. The Census place for the village alone has too few homes for steady figures.
When to book it
If you see water pooling under your air handler or around the drain line, the primary drain is likely clogged. In Waterford, where some homes are near the creek, moisture can also seep into the system. A clogged drain line can lead to water damage or a tripped float switch that shuts off your cooling. A tune-up clears the line and checks for any leaks.
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.
Or the sticker on the unit is from the last owners. That’s most houses, and it’s reason enough.
Choosing who tunes it up
Questions to ask anybody who books you, us included.
Yes. High iron and manganese levels can affect filters and coils. A good technician will ask about your well water quality and check for any buildup. This ensures your system runs efficiently and lasts longer, especially in a town like Waterford where private wells are common.
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.
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.
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.

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!

Questions
Cleaning the coil or clearing the drain line does not require historic district review. But if you need to move or replace the outdoor condenser, and it is in a visible spot in the Waterford Historic District, the County Historic District Review Committee may need to approve that change first. The tune-up itself is straightforward.
Once a year, ideally in the spring before the hot months. In Waterford, where some homes are near the creek and others have older systems, a yearly check helps catch wear early. If you had a flood or notice rust-colored water, book one sooner to check for any moisture or mineral buildup.
$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.
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.
