FURNACE WON'T TURN ON
No heat at all. Thermostat shows correct setting but furnace doesn’t respond. Likely causes: dead pilot light, tripped breaker, failed ignition, control board issue.
WEAK HEAT OUTPUT (NOT HEATING ENOUGH)
Furnace runs but doesn’t warm your home adequately. Temperature slowly creeps up or never reaches thermostat setting. Likely causes: dirty filter, pilot light weakness, heat exchanger crack, or system age. We test efficiency and identify the problem.
STRANGE NOISES OR VIBRATIONS
Banging, rattling, squealing, or grinding during operation. Loose components, worn bearings, or heat exchanger damage.
FREQUENT CYCLING ON/OFF
Furnace turns on and off rapidly instead of running for sustained periods. Wasted energy and poor comfort.
THERMOSTAT NOT RESPONDING
You adjust the thermostat but furnace doesn’t respond. Battery-powered thermostats: try replacing batteries first.
PILOT LIGHT ISSUES (OLDER SYSTEMS)
Pilot light won’t stay lit or keeps going out. Likely causes: thermocouple failure, gas valve issue, or airflow problem.
HIGH ENERGY BILLS
Unexpected spike in winter heating costs. Inefficient furnace operation, poor insulation, or system age.
SAFETY ISSUES (CARBON MONOXIDE CONCERNS)
Unusual smells, visible cracks in heat exchanger, or discolored flame. These signal potential carbon monoxide hazards. Turn off the system immediately and call for emergency service.
