Year-Round HVAC Maintenance Calendar
A season-by-season schedule keeps your heating, cooling and hot water running reliably and efficiently.
Spreading HVAC maintenance across the year keeps every system reliable and efficient. Here's a simple seasonal calendar.
Fall and winter
Fall: service the furnace/boiler/heat pump, change filters, test CO alarms, insulate condensate pipes, and check the water heater. Winter: monitor performance, keep outdoor heat pumps clear, and watch for issues.
Spring and summer
Spring: service cooling/heat pump for summer, clean coils, check the AC condensate drain. Summer: change filters, flush the water heater, and address any noises before fall.
Key takeaways
- Service heating in fall, cooling in spring
- Change filters every 1–3 months
- Flush the water heater yearly
- Test CO and smoke alarms regularly
