In between maintenance calls, you need to do the following to protect your heat pump and save energy:
Clean or change the air filter as recommended or, if you use the system more, at least once a month.
Remove foliage and debris from around the outdoor unit. Shrubs should be trimmed back at least 18 inches on all sides.
In winter, check for snow or ice buildup, as heat pumps need airflow to function properly.
Inspect the outdoor coils occasionally; if they are dirty, follow the manufacturer’s suggestions for cleaning them.
Clean the supply and return registers if they are dusty.
Keep all vents open so air can flow unimpeded, increasing system efficiency.
