How to Prepare Your HVAC System for Winter

Prep your heating system in September or October, before you depend on it. A fall checkup catches worn parts, carbon monoxide leaks, and efficiency problems early.

• Inspection: Includes filter service, thermostat calibration, electrical checks, CO leak testing, and burner cleaning.
• Filters: Replace or clean every one to three months; a dirty filter forces the furnace to work harder, wasting energy and risking damage.
• Thermostat: Switch to heat, confirm it fires the furnace, and update winter schedules.
• Seal & clear: Weatherstrip gaps around windows and doors, and keep at least 12 inches of clearance around vents.
