Similar to all other types heating systems, heat pumps can have issues and malfunction—they just have different types of problems than gas or electric furnaces. The main problems commonly associated with heat pumps are refrigerant leaks and ice buildup.
Refrigerant is evaporated in the unit outside in homes and businesses relying on heat pumps for their heating needs. This process absorbs the thermal energy from the outside air, and the resultant gas is then condensed in the inside unit, which releases the heated air into your home. With a refrigerant leak, your system eventually won’t have sufficient fluid to function. Once the refrigerant levels are low enough, the heat pump will break down. If you think that your system’s refrigerant levels are low, it’s important that you call in the professionals for repairs as soon as possible.
Ice buildup on the outside unit is also common in the winter, but less common here in south Florida. But, it can happen. During the winter, ice can build up on the outside unit. The pump pulling the thermal energy from the air causes the temperature to drop and condensation can form on the coil. Consequently, ice can form as the condensation freezes. To help prevent this from occurring, heat pump systems have a defrost cycle—if this is malfunctioning and your system is covered in ice, it’s time to call a trusted HVAC service company.
