The Complete HVAC Maintenance Schedule for Homeowners

Regular maintenance prevents breakdowns, extends equipment life, and keeps your energy bills low. Here's your complete maintenance schedule.

Monthly Tasks

Check and Replace Air Filters The most important DIY maintenance task. In peak season, check weekly and replace monthly.

Inspect Visible Ductwork Look for obvious gaps, damage, or disconnections in accessible ducts.

Clear Vents Ensure furniture, drapes, and objects don't block supply or return vents.

Quarterly Tasks (Every 3 Months)

Clean Supply Vents Remove vent covers and wash or vacuum dust accumulation.

Check Thermostat Batteries If your thermostat uses batteries, replace them at least annually.

Inspect Outdoor Unit Remove debris from around the condenser and ensure adequate clearance.
