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 Gainesville
Before anyone opens a panel, the tech needs to know what your heat runs on. Of the 4,951 owner homes in the Census place called Gainesville, 4,035 heat with utility gas, 856 with electricity and only 18 with propane. A gas furnace gets its pressure read against utility gas settings, a propane one against propane’s. Electric heat in houses this young nearly always means a heat pump; if that’s yours, tell us on the phone.
The visit runs the furnace through its sequence of operation, the steps it takes on every call for heat: the inducer fan clears the flue, a pressure switch proves the draft, the igniter glows, the gas valve opens, a sensor proves the flame, and only then does the main blower start. An original furnace in one of the 2,087 owner homes built in the 2000s has done that several times an hour on cold nights for close to twenty winters, and every step is a part that wears. Watching each happen in order is how a tune-up spots the one that hesitates.
The younger furnaces need the visit for another reason. About 1,900 owner homes went up from 2010 on, 428 since 2020, and there the parts are rarely the story. The first tune-ups write down the gas pressure and the temperature rise, the warm-up between the air going in and the air coming out, against the range on the rating plate. Next fall’s numbers get held up against this year’s, and a reading that drifts is a young furnace’s early warning.
Virginia Oaks, from 1994, watches its rooflines: the guidelines want chimneys masonry or enclosed, and any vent through the roof painted to match. A furnace there that still vents up a metal flue often shares it with the water heater; a newer high-efficiency one may run plastic pipe out a wall. Either way, the tune-up tests the switches that stop the burners when exhaust can’t get out. In Heritage Hunt’s four condominiums, the condo documents say who looks after each unit’s heat.
By the numbers

When it’s worth doing
In plenty of 2000s and 2010s houses it’s the bedroom over the garage. Prince William County Fire and Rescue says space heaters account for a third of home heating fires, so find out why before January. The temperature rise reading shows whether the furnace puts out what it should; if it does, the trouble is more likely the duct run to that room, and we’ll say so.
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.
A glance with the door off isn’t the same as letting the furnace go from the inducer’s first spin to the blower shutting off after the burners go out. Ask whether the tech watches one full cycle, start to finish.
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.

Questions
Yes, the same visit at $99. Propane runs at a higher pressure than utility gas, so the tech reads yours against propane’s settings. Mention it when you book.
$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.
