Lovettsville heats from late October to mid April, on propane and heat pumps.
Heat is the bigger job in Lovettsville. The NOAA co-op station in Purcellville, the closest one with long-term normals, averages a January low of 24.5 degrees and about 115 nights a year at or below freezing. Its median first freeze falls on October 25 and its last on April 16, so the heat carries the house for half the year, and a Lovettsville weather station read five below zero on January 23, 2025.
The Census counts about 44 percent of owner homes in town on propane and about 42 percent on electricity, and about 46 and 41 across 20180. Propane furnaces fail in the same places natural gas ones do, the igniter and the flame sensor first. A heat pump pulls its heat out of the outdoor air, and on a morning near zero there’s less to pull, so the electric backup takes on more of the work.
Snow is the other Lovettsville problem. Western Loudoun took 30 to 36 inches in the January 2016 blizzard, a spotter just east-northeast of town measured 30 inches in February 2010, and 6 inches had fallen just east of town by the morning of January 25, 2026. A high-efficiency furnace breathes through plastic pipes out a side wall, often low on the wall. Once a drift covers them, it shuts itself down on purpose, and brushing them clear usually brings it back.
Wind finishes the list. A Lovettsville station caught a 63 mph gust on February 16, 2025, and the February 2010 snow cut power across the county. A propane furnace needs electricity for its igniter, inducer and blower, so it goes cold in an outage too. If the heat doesn’t return with the lights, check the furnace switch and the breaker, then call us after the storm and we’ll go over the whole system.
Lovettsville houses, by the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.

What a failing furnace in Lovettsville usually does.
The heat pump is a block of ice
A light frost that melts off every hour or so is the defrost cycle doing its job. A solid shell, often from a gutter dripping onto the unit, won’t clear. Switch to emergency heat, keep the drip off it and call.
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 Lovettsville.
Questions worth asking anybody who comes out, us included.
Will they check outside the house, not just the furnace?
In winter a Lovettsville no-heat call can start outdoors: a buried vent pipe, a frozen condensate line, an iced heat pump. Ask whether the tech walks the outside of the system before pricing a part inside.
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 Lovettsville.
How cold does it get in Lovettsville?
The normals put the January low at 24.5 degrees, but on the night of December 23, 2022, after more than two inches of rain that morning, the wind chill in Lovettsville fell to nine below. On January 27, 2026, it hit five below, the lowest in Loudoun on that morning’s Weather Service list.
Can a heat pump heat a Lovettsville house at five below?
It keeps running, but its output drops as the outside air gets colder, so on the coldest mornings the backup heat carries most of the load. That’s normal. Backup heat running all day when it’s 40 degrees out isn’t, and the $99 diagnostic visit finds out why.
How much does furnace repair cost in Lovettsville?
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.
