Crankcase Heaters: What HVAC Owners Need to Know

Understanding Crankcase Heaters

Crankcase heaters are essential components in HVAC systems, designed to prevent refrigerant migration and condensation within the compressor during off cycles. This function is crucial in maintaining the efficiency and longevity of your HVAC unit, especially in cooler climates where refrigerant migration can cause significant damage.

Function and Role in HVAC Systems

The primary role of a crankcase heater is to keep the compressor’s oil warm, preventing refrigerant from mixing with the oil. When the compressor is off, refrigerant can migrate and condense in the crankcase, leading to a mixture that can cause severe damage upon startup. By maintaining a consistent temperature, crankcase heaters ensure that the refrigerant remains in the system’s evaporator and condenser, ready for efficient operation when the compressor restarts.

Types of Crankcase Heaters

There are several types of crankcase heaters, including:

• Strip Heaters: Attached directly to the compressor’s body.
• Belly Band Heaters: Wrapped around the compressor.
• Insertion Heaters: Inserted into the compressor’s oil sump.

Each type is designed to suit different system requirements and installation preferences.
