Atwood Heat Pump

Boy did I make a mistake buying this piece of ****.....first off the fan runs all the time when in A/C mode.....this weekend it got into the high 40's so I turned it to heat and it cycled on and off all night....the air coming out of the roof ducts was only 70 degrees when it was running.... inside never got above 67 degrees......could not get gas furnace to come on....when I called Atwood the bimbo I spoke to told me that was the way it was suppose to work because it was too warm inside the camper for the heat pump to work......duh.....If I was her supervisor and listened in on this call I would have fired her because she did not have a clue what she was talking about.......when I told her I had certificate in A/C and knew what I was talking about she brushed me off......so be careful if you are considering a Atwood air command A/C...

  • If it's new take it back and ask for replacement or refund - your credentials are enough to convince me. Any chance it's just a problem with the thermostat?

    I’d be surprised that a company the size of Atwood produces a product that doesn’t work.

    First off though, as Blofgren mentioned, a heat pump doesn’t really work with air temperatures below about 42 deg. F.

    While I do not have that brand, mine are Coleman, the thermostats have settings for gas heat, A/C, heat pump, and fan continuous or automatic.

    What does the operation manual for yours say about this? Is there a trouble-shooting section?

    It sounds like the installer messed up some wiring or something. I would suggest you get someone to look at your setup.

    The pump never satisfies the thermostat setting.....out put temp only reaches 70 degrees....it only runs a couple of minutes then shuts off....the control panel will not let me turn on the gas heater.....Dometic bought out Atwood so there is confusion as to who does what there. The instruction manual needs to be re written because it clearly states that the gas heat will not come on until it gets down to 45 degrees ......
  • I had my Coleman 15K heat pump running this morning. Fan never shuts off on it, but I have the temp knob turned up part way and have a comfortable 77º inside with compressor turning on/off. I didn't check output temps from it.

    It will put out heat down into the outside temps of high 30's. That only happens maybe a couple times in Jan. here. This morning low was 55º

    In regards to heat, a heat pump loses efficiency as the outside temperature drops. In the low to mid 40's my experience is that it is more efficient to run the furnace or other alternate heat. I have a heat pump both in my fiver and in my sticks and bricks home.

    The girl I was talking to said outside temp had nothing to do with the heat pump working it was the inside temperature that the heat pump got its heat from. She was clue less as to how the heat pump worked.......
