Our Atwood Air Command Heat Pumps are still blowing some juicy heat and it's 20°F outside and snowing and very windy. I can't complain. There are zero electric heat strips in these so this is all refrigerant action. I'm impressed. I can't say enough good about these. And frankly I'm thankful for them because they are putting out more BTU's than my space heaters would so we are staying toasty in Michigan for the holidays.

I have one too and love the fact that they come with a remote control so you can turn the temp up or down whilst driving down the road instead of putting your bus on cruise control and running back to adjust the temperature like some of the other units. :D
The only complaint I have is they are a bit noisier then some of the other heating units out there.
Wow must be nice to have cruise control. I have to either wait for a down hill or wedge a stick on the throttle. Lol

Replaced our two carrier's with a pair two years ago.. work great and lowest current draw of any unit's we have ever used .rdw
My plan was to install two more, but after I bought the first one to test it out, I heard they only work between 40 - 100 degrees. I frequently go into places i.e. thru Barstow where it can be 110+ degrees, so I need to find out more before buying another unit. I called the factory and they couldn't tell me the exact specs, so I plan on calling again before it gets too hot out and try to get someone else on the phone because someone must know. I was not very impressed with their customer service. I may end up getting a couple of Coleman units for the other units as I know they will keep me cool.
Their customer service is definitely spotty, but they did take care of me when I had an issue with one of the touch pads.

I wish I had such luck with the heat pump portion of my Atwood. At about 32F all it did was make all kinds of noise and barely produced any heat at all. I finally turned it off and turned on an electric heater instead.
Over 90% of the time I am using air conditioning so I rarely use the heat mode.
S&H, are you sure your bus isn't on fire? I've never had that kind of luck with a heat pump. Once the temp got below freezing, the pump couldn't find any heat to pump!
There have been advances in heat pump technology.
Yesterday's heat pump and today's are different animals.
The new refrigerant is a big part of it.
Where's the resident HVAC guy, to give us a detailed explanation?
happy coaching!

Some of the newer heat pumps are available with heat strips to supplement the heat pump at lower outside temps.

Really wondering where a true heat pump can find heat to remove from the atmosphere @ 20 degrees to put into heated living space...

They use the mixing of gas and pressure now they have heat pumps that will work below 0 I have a friend in Alaska they use heat pumps in their apartment buildings now,gone are the days of the old R22 heat pumps but the newer units don't blow the cold air like the old R22 units IMO

The same place your deep freezer does?
The coils on the outside of the freezer are warm, removing heat from inside the freezer box, and it is way down at -18C/ 0F.
Heat pump does the same thing.
There is "heat" out there to be transferred inside, advancing technology will set us free?
happy coaching!

My Amish friends and neighbors don't agree with this!
They say technology is the reason the world is such a violent mess!
;D BK ;D

The ones sold in Norway are labeled "polar" or "arctic" under the manufacturers brand name on the outside. Nobody complains about them.
I agree with the Amish, i have visited them in Penn. But they don't go to AZ where it gets over 100 degrees on a regular basis. :-)
Guys, I'm telling you, I have seen the new Fujitsu and Mitsubishi mini split heat pumps and they blow serious heat at temps down to single digits now. Trust me on this. My rooftops are doing it too. I showed you the temp gun showing almost 100°F air coming out at a screen shot of my cell phone showing that the temp was down to 19°F at that very moment. No electric strips. No juju. Just amazing tech and refrigerant.
