Protecting Your Compressor During Cold Snaps

A crankcase heater is a resistance heating element, either wrapped around the outside of the compressor shell as a belly band, or inserted directly into the compressor's oil sump, that stays energized during the system's off cycle in cold weather. Its purpose is to keep the compressor's crankcase oil slightly warmer than the surrounding refrigerant vapor, which prevents refrigerant from migrating into and diluting the oil during long periods when the compressor isn't running.

Without a functioning crankcase heater, refrigerant vapor naturally migrates toward the coolest point in the system during the off cycle, and in cold ambient conditions that's often the compressor's oil sump. When the compressor then starts up, that dissolved refrigerant flashes to vapor rapidly, creating foaming that carries oil out of the crankcase and away from the bearings and moving parts that depend on it for lubrication, a phenomenon called oil dilution or refrigerant migration. Repeated cold starts without adequate lubrication protection accelerate bearing wear and can lead to premature compressor failure.

This is a bigger concern on heat pumps than straight air conditioning systems, since heat pumps operate and cycle their compressors through cold weather rather than sitting completely idle all winter the way an AC-only system does. Georgetown doesn't see extended winters, but our occasional hard freezes and multi-day cold snaps are exactly the conditions where an unprotected compressor sees the most start-up stress, a compressor that's fine during a typical mild Central Texas winter can still take damage during a sharp cold event if oil dilution isn't managed.

Installation involves selecting a heater sized correctly for your compressor's crankcase volume and horsepower, mounting it securely against or inside the compressor housing per manufacturer specification, and wiring it into a control circuit, often through the defrost control board on a heat pump, so it energizes appropriately during the off cycle rather than running constantly and wasting energy. We test that the heater is drawing correct current and actually warming the compressor shell measurably above ambient before considering the installation complete.

If your system has experienced repeated cold-weather compressor issues, or if you're adding a heat pump in a home that previously ran cooling-only equipment, a properly installed crankcase heater is a relatively inexpensive way to add meaningful protection against a much more expensive compressor failure down the road.

Frequently Asked Questions, Compressor Crankcase Heater Installation

Do straight air conditioning systems need a crankcase heater? +
Less often than heat pumps, since AC-only compressors sit fully idle through winter rather than cycling in cold weather. Heat pumps benefit more because they continue running and cycling the compressor through cold snaps, which is when oil dilution risk is highest.
How does a technician know if my compressor already has oil dilution damage? +
Signs include unusually loud or rough compressor startup, especially after cold weather, along with abnormal oil appearance if the system is opened for other service. We evaluate compressor sound and performance history before recommending heater installation as a protective measure.
Does the crankcase heater run all the time? +
No, a properly wired heater is controlled to energize during the off cycle in cold conditions, often tied into the defrost control circuit on a heat pump, rather than running continuously, which would waste energy without added benefit.
Is a belly band heater different from an insertion heater? +
Yes. A belly band wraps around the outside of the compressor shell, while an insertion heater is installed directly into the oil sump. We select the type appropriate to your specific compressor model and how it was designed to accept a heater.
Will adding a crankcase heater void my compressor warranty? +
No, when installed to manufacturer specification a crankcase heater is a supported accessory, not a modification. We verify compatibility with your specific compressor model before installation.
