Heating & cooling
Maintain a heat pump
Because a heat pump may run for both heating and cooling, it benefits from two seasonal checkups and clear airflow year-round.
Recommended timingFilter monthly; professional service spring and fall
What to do
- Check the filter monthly and clean or replace it when dirty.
- Keep leaves, snow, lint and vegetation clear of the outdoor unit without bending fins or opening service panels.
- Keep supply and return registers open and unobstructed.
- Schedule heat-pump-qualified professional maintenance in spring and fall, including coils, drainage, electrical components, refrigerant performance and defrost operation.
