How can youtell if you have a heat pump?

I have a 07 Fleetwood Southwind 32V, has two roof mounted AC units, anyway to tell if one or both are heat pumps? Thanks

By the Model number of the AC unit, or you remove the top shrouds and IF you have a Heat Pump, you will see a solenoid/valve assbly mounted in the copper lines. It will have 4 copper lines going to it. Model number is the easiest way. Doug

If the compressor runs in your A/C unit and heat comes out your vents, you have a heat pump.

If just the fan in your A/C unit runs, you have an electric heat strip.

I presume you have Coleman AC's? Any indication on your thermostat? On the Dometic thermostat, there is a setting for "heat pump"
