Catlett heat is sized for a 17 degree night, and some winters go lower.
Fauquier County’s building criteria list 17 degrees as the winter design temperature, so heating systems here are sized to keep a house warm when it’s 17 outside. Plenty of Catlett winters go colder. NOAA’s Warrenton 3 SE co-op, about seven miles west-northwest, averages a January low just under 25 and five or so nights a winter at 10 degrees or colder, and it dropped to 3 degrees on January 7, 2014. Late January 2026 brought wind chills between zero and 10 below over the Piedmont.
Electric heat covers half of 20119’s owner homes, mostly as heat pumps with strips behind them. On a night near the design point, a heat pump running without a break and leaning on its strips is doing its job. Close to 100 nights a year here fall to freezing or below, from a median first frost around November 1 to a last around April 9.
About 29 percent run on propane, delivered to a tank on the lot. A propane furnace fails at the same few parts a gas one does: a dirty flame sensor, cleaned for $95 to $180, or a cracked igniter, $240 to $410. The difference is the tank. A long cold spell drains it faster than you’d guess, and a furnace that clicks and won’t light may just be out of fuel. Smell propane indoors? Get out, then call your propane supplier from outside.
Snow and ice bring their own calls. The Warrenton station measured 20.5 inches of new snow on January 23, 2016. A drift like that buries a heat pump on a low pad, or covers the plastic vent pipes a high-efficiency propane furnace breathes through, and either one shuts the heat off. The December 16, 2020 ice storm left up to half an inch at Opal, in southern Fauquier, and a heat pump cased in ice that thick needs a tech, not another defrost.
Catlett houses, by the numbers

Catlett
ZIP 20119 as a whole: every Catlett address, the village included. The Census place for the village alone has too few homes for steady figures.

- Electric heat here usually means a heat pump with electric strips as backup, and a heat pump stuck on those strips shows up on the electric bill.
- A few houses still burn heating oil. We don’t work on oil burners, but a switch to a heat pump or a gas or propane furnace is ours to price.

What a failing furnace in Catlett usually does.
The house stalls a few degrees short on the coldest night
In the teens, a house that holds 65 with the thermostat at 68 may just be at the edge of what the system was sized for. On a 35 degree afternoon it means something’s wrong: low refrigerant, a stuck defrost, or backup strips that never come on.
The heat pump blows cool air
A few minutes of cool air in winter is a defrost cycle, and that’s normal. Cool air all the time, or emergency heat running all day, is a call.
It smells the first time it runs
Dust burning off the heat exchanger smells for the first few minutes of the season, then stops. A gas smell is different: leave the house and call your gas company from outside.

How to pick the best furnace repair company in Catlett.
Questions worth asking anybody who comes out, us included.
Do they set a propane furnace up for propane?
Propane runs at a much higher gas pressure at the burners than natural gas, and a propane furnace has its own orifices and its own figure on the rating plate. Have the tech read the manifold pressure against that figure. Set wrong, the burners run lazy or too hot.
Will they price the part before they fix it?
Flame sensors, igniters and control boards all have a going rate. A tech who can’t tell you the number before starting is asking you to find out afterwards.
Do they look at the venting, not just the flame?
Getting the burners lit is half a heating call. Ask whether they check the flue and test for carbon monoxide while the panel’s open.
Do they know when a repair isn’t worth it?
A big repair on a furnace past 15 or 20 years deserves a replacement price next to it. A good tech puts both numbers in front of you and lets you choose.

Heating repair questions from Catlett.
The power’s back after a storm, but the heat won’t start. What do I check?
A heat pump usually has two breakers, one outside and one for the air handler, and a propane furnace has a service switch like a light switch near the unit. Make sure each is on, then give the thermostat a few minutes. If nothing happens, a surge may have fried the control board, $550 to $1,180; we’d confirm it on a $99 diagnostic visit.
How much does furnace repair cost in Catlett?
The diagnostic visit is $99. A flame sensor cleaned is $95 to $180; an igniter or flame sensor replaced, $240 to $410; a control board, $550 to $1,180; a blower motor, $670 to $2,400.
Should I repair it or replace it?
Fix the small parts on almost anything. Before a big repair on an old furnace, look at the replacement number: a furnace alone, keeping the air conditioner you have, runs $4,285 to $14,040 installed, and the HVAC estimator gives your number in about a minute.
