Furnace and heating repair in Lovettsville.

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.
