What it costs
$99 for one furnace, anywhere we work. The tech checks the gas pressure, the temperature rise, the safeties and the sequence of operation, which is the order the furnace lights, heats and shuts down in. A repair it turns up gets a written price first, and you decide.
Furnace tune-up, one system
$99
Heat pump, boiler or ductless mini split tune-up, one system
$99
Comfort+ membership, a heating maintenance visit every fall included
$199 a year
It’s priced per system, so a house with a second furnace for the upstairs is two tune-ups. A heat pump, a boiler or a ductless mini split is the same $99 a system.
With Comfort+ membership, $199 a year or $20 a month covers four visits every year: a heating maintenance visit in the fall, a cooling maintenance visit in the spring, a dryer vent cleaning, and a water heater flush with a sewer camera inspection. We book each one when it’s due.
What’s different in Aldie
Natural gas heats about 86 percent of Stone Ridge’s owner homes, and the association lists Washington Gas as the supplier. Across all of 20105 it’s about 78 percent, because the houses outside Stone Ridge lean more on propane and electric heat. The checks are the same on either fuel, but the numbers they’re held to aren’t, so say which yours burns when you book.
About one Aldie owner home in twenty burns propane, most of them outside Stone Ridge. A propane furnace is a gas furnace set up for a different fuel, with narrower orifices at the burners and a different spring in the gas valve, running at a manifold pressure well above natural gas. The tech reads it against the propane figure on the furnace’s label, and a missing conversion label goes in the write-up. The tank and its regulator are often the propane company’s; our part starts at the furnace.
In houses this young the furnace is often the high-efficiency kind, with two plastic pipes leaving through a wall or the roof and a small drain line beside it. Outside, leaves, a bird’s nest or a mulch pile can end up against those pipes. Inside, one of the safeties on the list is a pressure switch that has to prove the vent is drawing before the burners are allowed to fire, so a half-blocked pipe or a sluggish condensate trap shows up in the readings first.
Stone Ridge’s houses skew older, from a 2009 median against 2013 for the whole ZIP. On a furnace past fifteen, the parts that light the burners, the igniter, the flame sensor and the inducer motor, tend to tire first, and watching it light, run and shut down through full cycles is where that shows. Book in September or early October, while a part the visit turns up can be swapped on a mild day.

When it’s worth doing
On a high-efficiency furnace that usually means a safety switch saw something it didn’t like: a slow condensate drain, a dirty flame sensor, or an intake pipe blocked outside. It may try again on its own, which is easy to miss until the house is cold. The tune-up finds which one while the weather is still mild.
Propane runs at a different gas pressure than natural gas, so the tune-up checks yours against propane’s numbers.
At least half the houses here went up since 2010, so the furnace is often the one the builder put in. A yearly tune-up finds the small things while it’s young: a filter nobody changed or a weak igniter is a small fix in October and a cold house in January.

Choosing who tunes it up
Questions to ask anybody who quotes you, us included.
Ask before anyone comes out. Gas pressure and temperature rise are readings on a meter, so a real tune-up has numbers in it, not just a look at the filter.
Some tune-ups end in a list. Ask which items are failing now, which can wait a season, and what each one costs, before you agree to any of it.

Elvis Diaz from SwiftPro did a fantastic job of inspecting my HVAC system, he explained everything in a very professional way, for example, he recommended the right filter type to use. It is a job well done.

Questions
Yes, $99 for the furnace, whichever gas it burns. Before the visit, look at the tank gauge: a furnace that runs short of propane shuts down like a broken one, and the refill comes from your supplier, not from us.
Book it before deciding anything. A 2009 furnace is nearing the age most gas furnaces are retired, but its numbers settle the question, not its birthday. Readings in range mean it heads into winter with them written down; readings out of range come with a repair price on paper, so a fix and a new furnace can be compared side by side.
$99 for one furnace, and the same for a heat pump, a boiler or a ductless mini split. If it turns up a repair, you get the price in writing before any work, and you decide.
No. The furnace tune-up is its own visit at $99. The Heating Check and the Clean Heat deep clean, the one that takes the blower wheel out and cleans it, are separate offers with their own terms on our Clean Heat page.
