Top 6 Frequently Asked Questions

What is a Heat Pump?

A heat pump is a device that uses electricity to transfer heat from one area to another. It works by using a compressor to circulate refrigerant between an indoor evaporator coil and an outdoor condenser coil. The refrigerant absorbs heat from the outside air and transfers it to the indoor air, thus providing heating and cooling. Heat pumps are more efficient than traditional heating and cooling systems, as they consume less energy to do the same job.

What Causes a Heat Pump to Freeze Up in Winter?

A heat pump may freeze up in winter due to a variety of reasons. This includes a low refrigerant level, insufficient airflow, a dirty filter, or a faulty defrost cycle. A low refrigerant level means that the heat pump is not able to absorb enough heat from the air, resulting in frozen coils. Insufficient airflow means that the air is not able to circulate properly, resulting in ice buildup. A dirty filter can cause the air to be unable to pass through the filter, leading to an accumulation of moisture and ice. And a faulty defrost cycle can cause the heat pump to not shut off during the defrost cycle, resulting in an accumulation of ice on the coils.

How Can I Fix a Heat Pump Freezing Up in Winter?

The best way to fix a heat pump freezing up in winter is to take preventive measures to ensure that the heat pump does not freeze up in the first place.
