Book your maintenance visit. [Call Now (240) 338-0049](tel:+12403380049)[Schedule Service](/contact) Fully Insured Prompt Response Free Estimates Upfront Pricing Your furnace burns fuel to heat your home, which means skipping maintenance isn’t just bad for efficiency. it’s a safety issue. We’ve found cracked heat exchangers in Bowie homes where the homeowner had no idea carbon monoxide was leaking into their living space. Pentagon Air provides complete furnace maintenance for Prince George’s County homes that keeps your system running safely, efficiently, and reliably through every Maryland winter. ## When You Need Furnace Maintenance Annual maintenance is recommended for every furnace, ideally before heating season starts in October. If your furnace makes unusual sounds, produces a burning or musty smell, or heats unevenly across your home, maintenance is overdue. A yellow pilot flame instead of blue is a safety concern that needs same-day attention. And here's something a lot of homeowners don't know. skipping annual maintenance can void some manufacturer warranties. ## Our Furnace Maintenance Process We inspect the heat exchanger for cracks, clean the burner assembly, test the ignitor, check gas pressure, measure carbon monoxide levels at the furnace and register vents, test safety switches, inspect the flue and venting, clean or replace the air filter, and calibrate the thermostat. We run the system through a full heating cycle to make sure everything works right. You get a clear summary of what we found. no technical jargon. ## Furnace Maintenance Cost in Bowie Pricing varies by furnace type and whether additional work is needed beyond the standard maintenance. We give you the price before we start. No hidden fees. Regular maintenance costs a fraction of what an emergency repair or carbon monoxide incident would cost your family. ## Why Choose Us Pentagon Air technicians are factory-trained on gas, electric, and propane furnaces. We carry the tools and test equipment to handle anything we find during the visit. We've maintained furnaces in every type of Bowie home. from the older gas units in Old Bowie to the newer high-efficiency models in Woodmore. Appointments available, free estimates.
