Key takeaways
- Change the filter and clear space around outdoor units each season.
- Spring is for the air conditioner. Fall is for the furnace or heat pump.
- Book professional tune-ups early, before heat waves and cold snaps.
- Test thermostats and carbon monoxide detectors twice a year.
Spring: cooling
Replace the filter, clear leaves and debris from around the outdoor unit and trim plants back at least two feet. Check that the condensate drain is flowing and test the thermostat with a cooling call. Book a professional tune-up before summer.
Look for ice, odd noises and water around the indoor unit during the first run of the season.
Fall: heating
Replace the filter again, make sure vents are open and clear and test the thermostat with a heating call. Check carbon monoxide and smoke detectors and replace batteries. Book a furnace or heat pump tune-up before the first freeze.
If you smell burning dust on the first run, it is usually harmless and short-lived, but smells that persist or smell like gas need immediate attention.
What to leave to a pro
Cleaning coils, measuring refrigerant, checking electrical parts, testing combustion and inspecting heat exchangers need training and tools. A seasonal tune-up covers all of that and provides a record for warranties.
A maintenance plan bundles both visits with priority scheduling.

Quick answers
When should I schedule HVAC maintenance?
Early spring for cooling and early fall for heating, before demand peaks.
Can I clean my outdoor unit myself?
You can clear debris and gently rinse the fins with a garden hose with the power off. Leave deeper cleaning to a technician.
