Think of spring and fall maintenance as your system’s biannual health check. A little effort now can go a long way in preventing mid-season breakdowns.
✅ Spring HVAC Maintenance Checklist
-
Change air filters – Replacing filters improves airflow and air quality while reducing strain on your blower motor.
-
Clean coils and condensate drain – Dirty evaporator or condenser coils can lead to poor efficiency and compressor failure. Clogged drains can cause water backups and mold growth.
-
Test the thermostat – Make sure it communicates properly with your system and maintains set temperatures.
-
Inspect ductwork for leaks – Even small leaks can lead to a big loss in efficiency and comfort. Sealing ducts can improve performance by up to 20%.
-
Check refrigerant levels – Low refrigerant levels indicate a leak and reduce cooling efficiency.
-
Clear debris around the outdoor unit – Remove leaves, grass, or debris that may have collected over winter to ensure airflow.
-
Lubricate moving parts – Fan motors and belts work best when they’re not battling friction.
❄️ Fall HVAC Maintenance Checklist
-
Replace air filters (again!) – Dirty filters are a leading cause of HVAC problems.
-
Inspect the heat exchanger – Cracks in this component can cause dangerous carbon monoxide leaks.
-
Clean burners and flame sensor – Built-up dirt can prevent proper ignition, reduce heating power, or create safety issues.
-
Test ignition system – Make sure your system starts reliably as colder weather hits.
-
Check carbon monoxide detector – Change batteries and test it regularly—especially with gas heating systems.
-
Calibrate the thermostat – Ensure it reads accurately and maintains desired temperatures.
-
Ensure vents and flues are unobstructed – Make sure nothing is blocking airflow or preventing proper ventilation.
By scheduling professional inspections in spring and fall, you’ll stay ahead of problems, improve energy efficiency, and make sure your system is ready for whatever the season brings. Don’t wait until something breaks—make preventative care part of your routine.
