How Often Should You Service Your HVAC System?
Many homeowners wait until their heating or cooling system shows signs of trouble before calling in a technician, but by then, it’s often too late. If you’re unsure how often to service HVAC systems, this guide breaks it down by season and explains what regular maintenance really means for your comfort, energy bills, and equipment lifespan.
The Ideal HVAC Maintenance Schedule
Regular servicing includes cleaning, checking refrigerant levels, testing electrical connections, and calibrating thermostats, tasks that can prevent surprise failures when you need your system most. To keep your system running efficiently and avoid costly breakdowns, most professionals recommend the following HVAC maintenance schedule:
- Twice a year: Once in spring for your AC, once in fall for your furnace
- Annually: At minimum, a full system checkup if you use a combined HVAC unit
- Seasonally: Filter changes every 1–3 months and visual inspections
Yearly HVAC Checkup: What’s Included?
This yearly checkup proactive approach helps extend the life of your system and keeps your manufacturer warranty valid. A typical yearly HVAC checkup involves:
- Cleaning coils and condensers
- Lubricating moving parts
- Checking thermostat calibration
- Inspecting ductwork for blockages or leaks
- Verifying airflow and system pressure
- Testing ignition, burners, and electrical connections
Seasonal HVAC Care by System Type
Different HVAC systems require care at different times of year. Here’s a quick guide:
- Spring: Tune-up your air conditioner before the first heatwave
- Fall: Service your furnace before overnight temperatures drop
- Winter & Summer: Change filters and monitor system performance monthly
- Heat Pumps: These systems may require inspection twice a year due to year-round use
