Baraboo – October 01, 2026 -- Homeowners in southern Wisconsin should schedule HVAC maintenance in early fall, before freezing temperatures arrive, according to HVAC expert Gary Kowalke of Terrytown Plumbing, Heating & Cooling in Baraboo.

Waiting until winter risks rushed repairs and system failure

Kowalke warns that delaying maintenance until cold weather sets in often leads to reduced furnace performance and emergency breakdowns during freezing conditions. Scheduling service early allows technicians to catch issues before the heating system is needed for daily use.

Furnace checks cover heat exchangers, burners, and ductwork

Standard fall maintenance includes inspecting heat exchangers, checking burners and pilot lights, and cleaning or replacing filters. Technicians also calibrate thermostats and examine ductwork for leaks or blockages that can restrict airflow and raise energy use.
