Schedule Professional Inspection
Book a comprehensive furnace tune-up between September and October. A professional service includes heat exchanger inspection, burner cleaning, gas pressure adjustment, safety control testing, blower motor lubrication, and filter replacement.
Replace Air Filters
Dirty air filters are the leading cause of furnace problems during winter. Replace or clean your filter every month during the heating season for optimal performance and efficiency.
Test Carbon Monoxide Detectors
Winter is the highest risk season for CO incidents. Ensure detectors are working with fresh batteries on every level of your home and outside sleeping areas. Test them monthly.
Clear Vents and Registers
Keep all supply and return vents clear of furniture and debris. Check that outdoor intake and exhaust vents are free of snow, ice, and bird nests.
Critical Winter Maintenance Tasks
Heat Exchanger Inspection
A cracked heat exchanger can leak carbon monoxide into your home. Annual professional inspection is essential for safety.
Blower Motor Service
The blower motor moves warm air through your ducts. Lubrication and belt adjustment ensure efficient operation.
Gas Pressure Check
Proper gas pressure ensures complete combustion and maximum efficiency. Both high and low pressure cause problems.
Safety Control Testing
Limit switches, flame sensors, and rollout switches must be tested annually to ensure safe furnace operation.
Emergency Winter Preparation
Despite the best preparation, furnace emergencies can still happen during winter. Keep our phone number saved and accessible. Know the location of your circuit breaker panel and gas shut-off valve. Have space heaters available as a temporary backup heat source. If your furnace stops working, check the thermostat, circuit breaker, and gas valve before calling for emergency service.
If you smell gas or suspect a carbon monoxide leak, evacuate immediately and call 911 from outside. Do not operate any electrical switches, as sparks could ignite accumulated gas.
