Your HVAC system works hard all year long to keep your home comfortable—whether it’s battling a summer heatwave or keeping you cozy during freezing winters. But like any major appliance, your system needs regular maintenance to keep running efficiently and avoid costly breakdowns.
Here’s everything homeowners need to know about maintaining their HVAC system—and how it can save you money, improve indoor air quality, and extend the life of your equipment.
Why HVAC Maintenance Matters
Routine HVAC maintenance is more than just a checklist—it’s an investment in your home. Here’s why it’s important:
- Improves Energy Efficiency: A well-maintained system runs more efficiently, which lowers your monthly utility bills.
- Extends Equipment Life: Preventative care helps your system last years longer.
- Prevents Unexpected Breakdowns: Routine checks catch small issues before they become expensive emergencies.
- Improves Indoor Air Quality: Clean filters and coils mean cleaner air for your family.
- Keeps Your Warranty Valid: Many manufacturers require annual maintenance to honor warranties.
Seasonal HVAC Maintenance Checklist
Spring & Summer (Cooling Season)
- Change or clean air filters monthly.
- Clear debris from around your outdoor condenser unit.
- Check for refrigerant leaks or low levels.
- Clean condenser coils.
- Test your thermostat for accuracy.
- Inspect the condensate drain for clogs.
- Schedule a professional A/C tune-up.
Fall & Winter (Heating Season)
- Replace or clean furnace filters monthly.
- Inspect the heat exchanger for cracks or rust.
- Test carbon monoxide detectors.
- Check blower motor and belts.
- Inspect and clean ductwork (especially if you have pets or allergies).
- Schedule a furnace inspection and tune-up.
DIY vs. Professional Maintenance
There are several things you can (and should) do yourself—like changing filters and keeping outdoor units clean. But it’s also essential to have a certified technician perform a full inspection and tune-up at least once a year.
A professional HVAC technician will:
- Test electrical connections and controls
- Calibrate the thermostat
- Lubricate moving parts
- Measure airflow and refrigerant levels
- Identify and fix potential problems before they cause damage
How Often Should You Schedule Maintenance?
We recommend twice a year:
- Spring: To prepare your air conditioning for summer.
- Fall: To make sure your heating system is safe and ready for winter.
