How often should a heat pump be serviced?

Twice per year — once in spring before the cooling season and once in fall before the heating season. Heat pumps run year-round and need more frequent maintenance than furnaces or ACs alone.

Why is my heat pump icing up in winter?

Some ice on the outdoor coil is normal — heat pumps defrost automatically. If the unit is completely encased in ice and not defrosting, call for service. Check that the defrost cycle is working properly.

Should I cover my heat pump outdoor unit in winter?

No. Heat pumps run in winter and need airflow. Covering the unit prevents operation and can cause damage. Keep the area around the unit clear of snow and ice.

Why does my heat pump blow cool air in heating mode?

Heat pumps deliver lower-temperature air than gas furnaces (90–110°F vs. 120–140°F). This is normal. If the air feels cold (below 90°F), the system may have a refrigerant issue or be in defrost mode.

How do I know if my heat pump needs refrigerant?

Signs include: reduced heating or cooling capacity, ice on the refrigerant lines, and higher electricity bills. Have a technician check the refrigerant charge — low refrigerant means a leak.

Can I clean my heat pump coils myself?

You can rinse the outdoor coil with a garden hose to remove surface dirt. For a thorough cleaning with coil cleaner, use a professional.

What is the defrost cycle on a heat pump?

In heating mode, the outdoor coil can frost over. The defrost cycle temporarily reverses the refrigerant flow to melt the frost. You may see steam and the system may briefly blow cool air during defrost — this is normal.

How long does a heat pump last with proper maintenance?

Heat pumps typically last 12–17 years with proper maintenance. Because they run year-round, they may have slightly shorter lifespans than separate furnace and AC systems.
