What Makes Your Heat Pump Freeze Up in Midland, NC?

Heat pumps are one of the most common heating and cooling methods today. An experienced, professional HVAC technician is very familiar with heat pump problems and how to fix them. The following is a list of some of the most common causes for a heat pump to freeze up and what to do about it.

Insufficient Airflow

The outside unit needs to be kept clear of obstructions, including leaves, twigs, snow, and general refuse. If there’s no air flowing through the system, moisture may freeze on the components. Pay close attention to your unit when the temperature falls.

Freezing Temperatures and Precipitation

Rain or snow can fall on top of the heat pump’s cover. If temperatures are cold enough, that may turn into a sheet of ice. If this happens, it could eventually cause the coil to freeze.

Settling

Concrete slabs can settle over time as the ground underneath heaves, which is a process caused by repetitive freezing and thawing cycles. This uneven leveling will block the drainage path for ice melt and impede airflow, causing ice buildup. If you suspect this is your problem, contact an HVAC technician about leveling the unit.

Clogged Air Filter

A clogged air filter impedes airflow and allows condensation to form on the coil. HVAC technicians check air filters regularly to keep them clean. If you live in a particularly dusty environment, be sure to check the filter often and change it as needed.

Making sure that your heating and cooling system is in excellent condition is critical to ensuring it provides you with several years of efficient, trouble-free service. Contact Dulin Mechanical Services, Inc. in Midland, NC for all your heating and air conditioning maintenance needs.
