Maintenance Tips
-
Replace air filters every 1–3 months to maintain airflow and furnace efficiency.
-
Keep supply and return vents clear of furniture, dust, and debris.
-
Maintain 2–3 feet of clearance around the furnace for safe operation and proper airflow.
-
Inspect the condensate drain line regularly to prevent clogs and water buildup.
-
Check thermostat settings and operation to ensure proper modulating heating cycles.
-
Examine vent pipes and connections for leaks or blockages.
-
Listen for unusual noises such as rattling, humming, or uneven airflow indicating potential issues.
-
Clean blower compartment and internal surfaces to prevent dust buildup.
-
Test carbon monoxide detectors to ensure safe operation.
-
Schedule annual professional maintenance to inspect burners, heat exchanger, gas connections, blower motor, and safety controls.
