We’ve kept furnaces running through Bowie’s worst winters in homes across Belair, Chapel Forge, and Pointer Ridge. all because the homeowner spent an hour with us before the cold hit. ## When You Need Preventative Heating Maintenance The best time is October or November, before you start relying on your furnace every day. But if you've skipped a year or two, schedule it now. Warning signs include slow heating, a burning smell when the furnace first kicks on in fall, or rooms that won't warm up. Furnaces that haven't been maintained are more likely to fail during the worst cold snaps. exactly when you need them most and when techs are hardest to get. ## Our Preventative Heating Maintenance Process We inspect the heat exchanger for cracks, test gas connections and pressure, clean the burner assembly, check the ignitor, test safety controls, and measure airflow. We also check the blower motor, lubricate bearings, and calibrate the thermostat to make sure it's reading correctly. If we find anything that needs attention, we explain it clearly and give you options. not a scare pitch. The visit takes about an hour. ## Preventative Heating Maintenance Cost in Bowie Maintenance pricing depends on your furnace type and condition. We quote upfront before any work begins.
