Transitioning a Heat Pump From Cool to Heat

As cooler Washington temperatures approach, you will need to transition your heat pump from being a cooling source to supplying heat. It is time to schedule maintenance before temperatures drop and you need the heating system to function properly.

Tasks for the homeowner:

• Replace the air filter.
• Remove any growth from a two to three foot area around the outdoor section of your heat pump.
• Clean out the coils before cold weather makes this difficult.
• Check your thermostat settings and adjust for cold weather.
• Flush and clean the drain line. Remember to prime the trap, if necessary.
• If your unit uses electric heat, check all of the wiring for discoloration and heat damage.

Tasks for professionals:

• Have the refrigerant checked to ensure there is a safe level. Refrigerant levels need to remain consistent, even in the cold weather.
• Electrical connections will be inspected to check for exposed wiring or loose connections.
• The blower motor should be oiled and wheels should be inspected for balance.
• Check the energy efficiency of your unit. If any problems are present, they should be repaired before operating the heating system.
• Check and clean the evaporator coils.

Transitioning your heat pump to heat for fall and winter by performing the necessary maintenance tasks will minimize the risk of a breakdown, improve indoor air quality, and extend the life of your system components.
