I will be living part time in my MH during the winter. I was wondering if I should cover my AC units or do they need to be left open while using the heat pumps?

Thanks,

I'm not sure what heat pumps are, but I've seen a few others who live year round in their RV's with covers on them in the cooler months.

We thought about it, but I havent found any that can be left on while traveling and we tend to move so much, I thought it would be a hassle to continually be climbing up and down to put the cover on.

The heat pump is the heating part of the AC unit. I will not be moving my MH, so leaving covers on is not a problem there. I am trying to find out if the unit uses outside air or just recirculates the interior air to heat.

Thanks, Chris

If your roof AC actually has a air heat pump, then you do not want to cover it. Air heat pumps draw heat out of the outside air and usually do not work well below 32 degrees.

Thanks for the info. I do have a furnace that kicks on around 40 deg. I will leave the ac units uncovered.

Thanks

A heat pump is also called reverse cycle A.C.It cools the interior and blows hot outside when you want AC and cools the outdoors and blows the hot air inside when you want heat.It can't be used if covered.

i would like to add if you have a electric heating element on your a/c unit as i do, you can cover the unit because the compressor section is not working only the inside circulator fan

Do you gain anything by covering it? Seems if there is a heat source you probably want the ventilation that is provided by the cover that is currently on it. Just a safety thought.

I would suggest that maybe a cover on the inside, remember you must take the cover off before you move. I have seen some where a simple white trash bag around the frame looked good. I don't like walking or going on my roof. So its something to keep in mind.

A heat pump needs air to work. The electric heat strips don't usually start till it is in the low 30s.I would not cover the unit.

The heat pump is just a reverse cycle A/C. The cold evaporator is out side and the warm condenser is inside. This accomplished with a reversing valve to switch the lines to the coils.

So when the out side air is to cold, the heat can not be used to warm the coil and evaporate the refrigerant. The coil will ice over and have to defrost or shut down.

So you do have to have the coil uncovered to operate the heat pump.
