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 Bristow
Gas heats 9,625 of the 11,087 owner homes the Census counts in Linton Hall. In a Bristow house with a basement, the builder usually set the furnace in the unfinished part, beside the gas water heater. Twenty years on, plenty of those basements are family rooms and guest suites, and the furnace sits in whatever utility room got framed in around it.
That matters most to an original furnace. The 80 percent models of the build-out years burn air from the room around them and send their exhaust up a metal flue, often shared with the water heater. Close one into a small room behind a solid door and it can run short of air. The tune-up runs the furnace through its whole sequence, and a starved burner tends to show itself there: a flame that lifts or wanders, or a safety that trips.
Plenty of 2000s furnaces here have already been replaced, and so have most of those in the 1990s houses, about one Linton Hall home in five. The newer ones are usually high-efficiency models with two white plastic pipes through a side wall. They make water as they burn, so the safeties a tune-up checks include the pressure switch that stops the burners when that water can’t drain or the exhaust can’t leave.
The Census puts 149 Linton Hall owner homes on propane, and toward Brentsville and along Bristow Road, outside the Census place, nobody counts at all. A propane furnace costs the same $99 to tune up, its gas pressure read against propane’s settings. About 1,280 owner homes heat with electricity, which in houses this young usually means a heat pump, and a Linton Hall heat pump’s autumn visit runs that same $99.
By the numbers

When it’s worth doing
Holiday bins and paint cans: a finished basement’s spare corner fills fast. The county’s fire and rescue department wants a three-foot ring around the furnace kept clear of anything that can burn. Clear it before the tech comes.
A furnace that went in with the house is close to 20 years old on a lot of these streets. That’s the age when inducer motors and control boards start to go, and a yearly look finds the tired ones before a cold night does.
Up there it’s the one nobody looks at until the bedrooms go cold. A tune-up gets somebody up the ladder before that.
Safety and paperwork

Choosing who tunes it up
Questions to ask anybody who quotes you, us included.
On a furnace from the build-out years, age changes what a finding means. A weak part on a ten-year-old furnace is a repair; on one past twenty, it’s the moment to price the repair and a replacement side by side. Ask for the year off the rating plate beside the findings.
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
After the air conditioning goes quiet and before the heat comes on for good, usually late September into October. A repair the tune-up finds then can be fixed on a mild afternoon, with nobody waiting on the heat.
Prince William’s fire and rescue department asks households to clear furnace vents of snow during and after a storm. A buried pipe makes the pressure switch stop the burners, and the house cools until it’s clear. Brush the snow off by hand, and call us if the heat doesn’t come back.
$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.
