Frequently Asked Questions About Furnace Repair in Largo, MD
Yes. The flame sensor sits directly in the burner flame and generates a micro-amp electrical current when heated to prove to the control board that fire is present. Over time, silica and carbon coat the metal rod, preventing flame detection and causing the furnace to shut off its gas valve after 3 to 5 seconds. Cleaning or replacing this sensor is a routine, fast repair for our Largo, Maryland specialists.
Yes. Modern thermostats communicate low-voltage signals (24VAC) to the furnace control board. Dead internal batteries, damaged wiring, loose C-wire connections, or faulty internal relays will prevent your furnace from receiving the heating call. Our technicians in Largo, Maryland test control circuit voltages and can re-wire or recalibrate your thermostat during the service call.
During warm summer months, ambient dust settles onto the furnace burners and heat exchanger surfaces. During the first cold snap, this thin layer of dust burns off, producing a mild, transient burning odor that typically disappears within 30 to 45 minutes. If the smell persists, smells of burning plastic/wiring, or produces visible smoke, shut down the system and call (877) 719-1221 immediately.
First, verify that your thermostat is set to "Heat" mode with the setpoint at least 5 degrees above current room temperature. Check that the emergency power switch mounted on or near your furnace is in the "On" position, and inspect your home electrical panel for a tripped heating breaker. If the blower runs but only delivers chilly air, or if you hear repetitive clicking without ignition, call (877) 719-1221 immediately for fast heating assistance in Largo, Maryland.
High-pitched screeching or metallic grinding usually signals failing sleeve or ball bearings inside the blower motor, or a misaligned blower wheel scraping against the housing. Operating a furnace with damaged bearings can overheat the motor and burn out internal electrical windings. Our Largo, Maryland technicians can lubricate, re-align, or replace the blower motor assembly promptly.
Electric furnaces do not use combustible fuel or heat exchangers; instead, they pass high-voltage electric current through heavy-duty nichrome heating elements. Common electric furnace repairs involve replacing broken heating coils, stuck electric sequencers, faulty contactors, or blown thermal fuses. Our technicians in Largo, Maryland service both electric and gas heating configurations.
