During cold periods with those having heavy snowfall or prolonged sub-zero temperatures, heat pumps can have operational challenges due to snow and ice build up around the fan or heat exchanger.
High upfront costs
Challenges in sustainability of heat transfer fluids
Challenges with heat pump valve failures
Cooling problems with heat pumps
Leakage of heat pump refrigerants
Noise challenge with heat pump operations
Design challenges for heat pumps
Poor heat pump installation
Challenges in cold temperature operations
Challenges with heat pump operations and performance in cold regions
