Heat Pump
How do you know if one of the AC units is also a heat pump?
We were told our 2018 3731 FL was equipped with a a heat pump.

If you have a heat pump for 1 of your units, you should have a heat pump setting for 1 of your units on your thermostat.

Nothing but furnace and cool on both so apparently salesman didn’t know what he was talking about.
Thanks for your help.

2018 units are supposed to have a heat pump. On ours (3810MS), it is the rear AC unit and when you scroll through the heat/cooling/fan settings, the last two are furnace and heat pump. In yours since it is a FL, I would suspect that it would be in the front one. Our front one does not have this feature.

Our 2017 has heat pump feature on the rear unit so I would think yours should be the same.

Our 1 heat pump is on the rear unit. It shows up on the thermostat after furnace.
One member yesterday said his High Country has 2 heat pumps. Ours is also wired for a 3rd AC but has no thermostat for it.

Neither rear or front thermostats have anything on them that says heat pump.

The heat pump will be in the main A\C unit only the front unit is A\C only if you scroll through the t\stat after furnace should be heat pump.

Our High Country 381TH came with heat pump feature on BOTH A/C units. Not sure if that was a special order or not. That's a great thing for us as I don't like to run the gas furnace and we don't camp in the extreme cold anyway. Besides the wife cuddles tighter when it is a bit cold in the bedroom........

On our 3791RD I've noticed that both thermostats have a heat pump setting. Where we are currently and in our driveway at home, the outside temps are too cold and the humidity is too high to get much from a heat pump. For the best from a heat pump, the air should be dry and not colder than ~45F.

Not sure if the RV heat pump is different than a home version, but I have one at my house in North Idaho and it works great at temperatures above 32 degrees.

It may depend on size or brand of heat pump or size or brand of air conditioner. Our SOB MH has 3 ceiling airs with heat pumps. This morning in N. Ft. Myers it was around 37 degrees and they worked great! Brought the inside of the coach up to 70 degrees in about 5 minutes. On our thermostat we can only select "air" or "HP".
So like others have indicated, if you scroll through the "mode" options on your thermostat and it doesn't say "HP" or "Heat-P" or something similar then your airs probably don't have it.

When you run your heatpump do you run it in auto mode, high fan or low fan?

We just bought and are camping in our new 321MK High Country and our front AC unit has a heat pump. It got down to about 39 degrees last night and between the heat pump and the electric fireplace, we were toasty all night.

We have never used the heat pump. Does it run off electric or gas?
