It’s common practice for condensing units for air conditioning and refrigeration systems to be located outside the building or home for two reasons. First, the cooler outdoor ambient temperatures help reduce the amount of heat absorbed in the evaporator section, making the unit run more efficiently. Keeping the condensing unit outside the structure also reduces noise while it’s running. When the unit isn’t in operation, however, there is a risk of refrigerant migration and the potential for it to mix with the oil, which can lead to loss of efficiency and equipment damage. A crankcase heater for your HVAC/R compressor can eliminate these issues.
