As the weather cools off, it’s time to start up your heating system for the season. If you rely on a heat pump, it will need slightly different care than a furnace would to keep it running smoothly. Beyond switching your thermostat to heat, here’s what you need to know.

How to Prepare Your Heat Pump for Cold Weather

1. Clean Off the Outdoor Unit

Your outdoor unit needs to absorb heat from the air to warm your home. To do that, it needs to be exposed and clean so there’s no insulating layer of dirt preventing a heat transfer. 

Remove the cover if there is one, then use a hose to spray down the unit, removing any leaves or other debris as you wash off the dirt. If plants are crowding the unit, trim them back to give it at least a foot of space to allow airflow.

2. Check the Filter

Your air filter keeps dust out of the inside of the heat pump and improves air quality throughout the home. When the filter is clogged, it can’t do these jobs, and it also constricts airflow and makes your unit’s fan work harder. 

To check the filter, hold it up toward a bright light source like the sun. If you can’t see light through it, it’s clogged. If it’s a reusable one, it needs to be washed; otherwise, replace it.

3. Uncover the Vents

The air intake and heating vents for your heat pump need to be clear. This prevents the fan from straining, and also allows the unit to deliver warm air to the room where it’s needed. Move any furniture or other belongings that might be sitting on or in front of heating system vents.
