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 Centreville
In a Centreville house that heats with gas, the furnace and the air conditioner almost always share one blower. By the first cold night that blower has spent the summer pushing cooled air up through the house, while the burners haven’t lit since spring. The sequence check watches the inducer start, the igniter glow, the burners light and the blower follow, and a part that got lazy over the summer shows up as a step that comes late or not at all.
With the median house built in 1990, Centreville furnaces come in two kinds. Some still vent up a metal flue, often one they share with the gas water heater, and there the safeties a tune-up tests include the one that cuts the burners when exhaust rolls back out of the draft hood instead of rising. The rest have gone high-efficiency: two white plastic pipes to the outside and a trap that drains the water the furnace makes. On those, a sluggish trap trips the pressure switch, and the furnace locks itself out on a cold night.
A gas pressure check has two numbers in it: what reaches the furnace from the meter, and what the gas valve passes on to the burners. Fairfax County’s utility list puts most of the county on Washington Gas, so here the first number is nearly always Washington Gas’s supply arriving at the furnace. About one Centreville home in a hundred burns propane from a tank instead; that furnace gets the same tune-up, read against propane’s numbers.
The other quarter of Centreville owners heat with electricity, mostly a heat pump backed by strips in the air handler, with no burner anywhere in the house. That heat pump gets its fall tune-up at the same price, $99 a system.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
When it’s worth doing
On a townhouse with a high-efficiency furnace, the two plastic pipes often leave low through the back or side wall, where leaves, mulch and drifting snow pile up. A blocked pipe shuts the furnace down. Find yours before the leaves drop and keep both ends clear all winter.
Up there it’s the one nobody looks at until the bedrooms go cold. A tune-up gets somebody up the ladder before that.
That’s the night every furnace in town gets asked to work at once. A tune-up in the fall finds a weak part while you still get to choose when it’s fixed.
Safety and paperwork
Fairfax County Fire and Rescue says to have the heating system cleaned and checked by a professional every year, and to keep anything that burns at least three feet from the furnace and the water heater. Source.

Choosing who tunes it up
Questions to ask anybody who quotes you, us included.
A gas furnace has two: what arrives from the meter and what the valve feeds the burners. Ask for both, plus the temperature rise, and where each should sit for your furnace. Numbers on paper are something you can compare next fall.
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 did an excellent job cleaning our condo’s HVAC system. He was very knowledgeable about maintaining the unit and the price was very reasonable.
Questions
One brings outside air in for burning and the other carries the exhaust out, which tells you it’s a high-efficiency furnace. Keep firewood, mulch and snow away from both. If either one gets blocked, the furnace shuts itself off rather than run without it.
No, but it’s the last easy month. Once the nights stay cold, every furnace on the street is running, and a repair the tune-up turns up is one you’d rather schedule on a mild afternoon. Aim for late September or early October.
$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.
