Regular HVAC maintenance is the single most cost-effective thing you can do to extend your system’s life and prevent expensive breakdowns.

Why Maintenance Matters

A neglected HVAC system runs harder, consumes more energy, and fails sooner. A well-maintained system can last 15–20 years. Skipping maintenance means 10–12 years, plus higher energy bills every month in between.

Spring Checklist (Before AC Season)

DIY tasks:

  • Replace air filter (if not done in the last 1–3 months)
  • Clear debris from around the outdoor condenser unit (leaves, cottonwood, mulch)
  • Straighten any bent condenser fins with a fin comb
  • Test the AC by running it for 10–15 minutes; verify cool air is coming from vents
  • Check condensate drain line — pour a cup of diluted bleach down the drain pan

Professional tune-up includes:

  • Refrigerant level check and leak test
  • Electrical connection tightening
  • Capacitor and contactor testing
  • Coil cleaning (indoor and outdoor)
  • Blower motor inspection
  • Safety control testing

Fall Checklist (Before Heating Season)

DIY tasks:

  • Replace air filter
  • Test the heat — turn to heat mode 10°F above current temp, verify warm air
  • Check vents — ensure all supply and return vents are open and unobstructed
  • Test carbon monoxide detectors (gas systems)
  • Inspect the area around the furnace for stored flammables

Professional tune-up includes:

  • Heat exchanger inspection (critical for gas systems — cracks can cause CO leaks)
  • Burner cleaning and combustion analysis
  • Ignitor and flame sensor testing
  • Flue inspection
  • Gas pressure testing

Year-Round Tasks

  • Filters: Replace every 1–3 months. More frequently with pets or allergies.
  • Thermostat: Test that it responds correctly. Consider upgrading to a smart thermostat.
  • Vents: Keep furniture and rugs away from supply and return vents.
  • Outdoor unit: Keep a 2-foot clearance around the condenser.

Signs Your System Needs Attention Now

  • Unusual noises (banging, squealing, clicking)
  • Higher energy bills without a weather explanation
  • Uneven heating/cooling between rooms
  • System cycling on and off frequently
  • Visible ice on the indoor unit

Don’t wait until your system fails in the middle of summer or winter. Schedule your tune-up in the shoulder season when technician availability is best and response times are fastest.
