Book your furnace tune-up
Leesburg heat after a summer off: mostly gas, some propane, old chimneys and closet furnaces.
Natural gas heats about two thirds of the owner homes inside the town limits and about four in five out in Lansdowne. Propane is the small share, roughly one owner home in forty in town by the Census count, usually where no gas main runs. Either fuel gets the same visit, but not the same numbers: propane runs at a higher pressure than natural gas, and the tech holds yours to the figure for your fuel on the furnace’s rating plate.
Houses from the 1980s and 90s are the biggest slice of town, about 7,000 of them, and where one has moved to a high-efficiency furnace, that furnace makes water as it burns. Over a summer off, its drain trap can dry out or gum up, and a trap that can’t drain backs water up until the pressure switch stops the burners. The tune-up runs the furnace long enough to make water and watches it leave.
Downtown is the exception. The Census puts around 380 of the town’s homes before 1940, many in the Old and Historic District, where the Town’s design guidelines ask owners to keep their chimneys. Where a gas furnace still vents up an old masonry flue, the fall visit carries more weight: a chimney cold since spring can be slow to start drawing, and one safety a tune-up tests is the switch that stops the burners when exhaust spills back instead of rising. It’s why the county’s yearly advice, below, names chimneys too.
Close to four in ten Lansdowne homes are in condo and apartment buildings, where the furnace is often a compact unit in a hall closet. If that closet door has slats or a grille, it may be how the burners get their air, so keep coats off it and never swap in a solid door.

- Most homes here heat with gas, so gas pressure is the first reading a tune-up takes.
The Loudoun County side
Lansdowne only. It’s the one Census place outside the town limits, so the farms and lots beyond it aren’t in these figures.

What a furnace tune-up costs in Leesburg.
$69 for one furnace, regularly $99, 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$69
- Furnace tune-up, regularly$99
- Heat pump, boiler or ductless mini split tune-up, one system$69
- 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 $69 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.
When a furnace tune-up earns its keep in Leesburg.
A hot dust smell the first cold morning
Usually it’s summer dust on the burners cooking off, gone by evening. If it lingers, or smells like hot wiring, turn the heat off and book a visit. If it smells like rotten eggs, that’s gas: get everyone out and call from outside.
It’s still the builder’s furnace
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.
Before the first cold night
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.
What the county says about furnace care in Leesburg.
Town of Leesburg
Inside the town limits, fire and rescue is Loudoun County’s system, answered from the Leesburg Volunteer Fire Company’s Station 1 on West Loudoun Street and Station 20 on Plaza Street, so the county’s heating and carbon monoxide advice applies in town just as it does in Lansdowne. Source.
Loudoun County
In its fall clock-change reminder, Loudoun County’s fire and rescue system tells residents to check their carbon monoxide alarms, and recommends one outside each sleeping area and on each level of the home, tested monthly. Source.
How to pick who tunes up your furnace in Leesburg.
Questions to ask anybody who quotes you, us included.
Do they say what the tune-up checks?
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.
Will they tell you what can wait?
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.
What our customers say.
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.

Furnace tune-up questions from Leesburg.
Does a heat pump get a fall tune-up too?
Yes, at the same $69 a system, regularly $99. Close to three in ten owner homes in town heat with electricity, mostly by heat pump, and a boiler or a ductless mini split is the same price as well. Anything the visit turns up gets a written price before any work.
When should a Leesburg furnace get its tune-up?
After the air conditioning goes quiet for the year and before the first frost, usually September into October. The furnace has sat since spring, a part it needs can be ordered on a mild afternoon, and you meet the first cold night knowing what it read.
How much is a furnace tune-up in Leesburg?
$69 for one furnace, regularly $99, 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.
Is this the Heating Check or the Clean Heat?
No. The furnace tune-up is its own visit at $69. 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.
