HVAC Maintenance Checklist (Homeowner)

Professional maintenance is vital, but homeowners can significantly extend system life with three simple habits. First, change your filters every 30-90 days; a dirty filter is the #1 cause of blower motor failure. Second, keep your outdoor AC unit clear of weeds, mulch, and debris to ensure proper heat transfer. Third, keep your indoor vents open and unblocked by furniture—closing vents actually increases pressure and strain on the system. These basic steps, combined with a biannual Hoosier Daddy tune-up, can keep your system running for 15-20 years.
