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 Catharpin
The Census counts 334 owner homes in ZIP 20143. About one in three heats with propane, and nearly half use electricity, usually a heat pump. Only about one in fourteen burns natural gas. That mix means the tech needs to know your fuel before the visit. A propane furnace has a tank and regulators; a heat pump has coils and a refrigerant circuit. The tune-up covers the specific parts for your system, not a generic checklist.
The median home was built in 1986. Many of those systems are original. Propane furnaces from that era often vent through a masonry chimney or a shared flue. The tune-up checks the draft and the safeties that stop the burners if exhaust lingers. If your home has a heat pump, the tech checks the refrigerant pressure and the electrical connections. Both types get the same $99 price, because the labor and diagnostic time are comparable.
Catharpin sits in a low basin near Little Bull Run. The gauge at Artemus Road recorded its highest crest in July 2025. If your furnace is in a basement or crawlspace, water intrusion is a real risk. The tech checks the area around the unit for signs of past flooding. Water damage can corrode electrical components or warp heat exchangers. Catching that early prevents a failure during a cold snap when you need the heat most.
Prince William County Fire and Rescue advises an annual inspection of heating systems to ensure fumes vent properly. They also recommend CO alarms on every level. The tune-up includes checking the combustion air and the exhaust path. If you have a propane tank, the tech verifies the pressure at the furnace valve. This ensures the flame is stable and the heat exchanger runs at the correct temperature, protecting the unit and your family.
When it’s worth doing
Catharpin’s heavy propane use means many homes have tank-based systems. Pressure can fluctuate with weather and tank levels. A tune-up reads the pressure at the valve and adjusts it to the manufacturer’s spec. For electric heat, the tech checks the capacitors and contacts, which often fail silently until the system shuts down.
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.
The home inspector ran the heat for a minute. A tune-up runs it through a full cycle with the panel off, and tells you what the last owners left you.

Choosing who tunes it up
Questions to ask anybody who quotes you, us included.
Yes. Whether you heat with propane or a heat pump, the visit is $99. The tech adjusts their checks to your fuel type, reading gas pressure for propane or checking refrigerant and electrical components for electric. You get the same thoroughness regardless of the system.
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
The area is rural, with many homes built before natural gas lines reached the neighborhood. Propane tanks offer a reliable heat source in those locations. The Census shows about one in three owner homes uses propane, making it a major fuel source here. The tune-up accounts for this by checking tank connections and regulator performance.
Tell the tech when you book. Little Bull Run has flooded nearby roads in recent years. If water reached your basement, the tech will inspect the furnace for corrosion and electrical damage. They will clean or replace affected parts before testing the system. This prevents a breakdown during winter and ensures the unit vents safely.
$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.
