You might be astonished to learn that a heat pump can freeze up even in the summer in Frederick, MD. Understanding the causes of freeze-ups and how to prevent them is essential to ensuring the optimal performance of your heating and cooling system. Below are some causes and how to solve them.

1. Dirty Coils and Filter

Dirt and debris on the coils and air filter have a tendency to inhibit airflow and cause the coils to freeze. Regular heat pump maintenance is essential to ensure your system functions efficiently and avoids freeze-ups. Most, if not all, maintenance visits include inspecting the coils and the air filters.

2. Does Your Heat Pump Have Low Refrigerant Levels?

Your heat pump’s refrigerant levels may get too low due to refrigerant leaks, which could lead to the evaporator coil freezing. To prevent low refrigerant levels, have a qualified expert service your heat pump at least twice a year.

3. Issues with the Thermostat

If the thermostat level isn’t set correctly, your heat pump may work too hard and eventually freeze. Consider adding a smart thermostat to notify you when your system needs maintenance or filter changes. From Maryland to Malaysia, you can use your smartphone to access the controls and thermostats in your house.

4. Malfunctioning Defrost Controls

Malfunctioning defrost controls can cause ice to build up on the outdoor unit, leading to freezing. Is your system suffering from this problem? If so, contact an experienced Comfort Specialist to examine and fix the defrost control issues.
