Coleman RV Air Conditioner Heat Strips

What does a Coleman heat strip do in an RV air conditioner?

A heat strip is an electric resistance heating element that mounts inside the ceiling assembly of a Coleman RV air conditioner, letting the unit blow warm air on cool mornings without firing up the furnace. It runs on 120V AC shore power or generator, so it is best suited for campground use rather than dry camping. Pair it with the matching Coleman Power Saver HP ceiling assembly for ducted installations when replacing a complete system.

How do I know which Coleman heat strip fits my AC unit?

Match the heat strip to your specific Coleman-Mach model number and ceiling assembly type (ducted vs non-ducted). Check the model label on the rooftop unit or the inside ceiling assembly before ordering, and verify whether your thermostat supports heat strip operation. If the original unit shipped without a heat strip, confirm your ceiling assembly has the wiring harness and breaker capacity to accept one.

Can I run a heat strip and the Coleman Soft Start at the same time?

Yes. The heat strip and compressor circuits are independent, and adding a soft start kit reduces inrush current when the compressor cycles, leaving more headroom for the heat strip load on a 30 amp service. See our Coleman RV air conditioner soft start collection for compatible kits.

Is the heat strip a replacement for an RV furnace?

No. A heat strip typically produces around 5,600 BTU of supplemental heat and requires 120V AC power, so it will take the chill off in mild weather but will not replace a propane furnace in freezing conditions.
