This heat pump version of this unit does have limits on heating, but works fine for most, as long as not too cold outside.

HOWEVER - it has a known flaw. When it gets cold outside, like 40 degrees or cooler, the heat will not turn on. The fix is you have to relocate the intake temp sensor,to inside your house - then it'll work fine. This is detailed on a few Reddit posts, and is an easy modification to make.

Overall, love these untis, but they will go on sale for $300 for the heat-pump ones if patient - have a few Toshiba ones (rebranded Midea's) myself and they are great!
The Danby version of this dual hose is on sale today. Item 1691101 Model DPA100B9IWDB-6. It's $299.99 now, sale ends today. Danby warranty 2 yrs vs Midea 1 yr.
I posted this deal last time and got it. I haven't used it so can't tell you how it is compared to the midea. I have the midea with heat and it's great so far.

Shows to be list price at Costco, but this is the lowest price I could find for this unit amongst other retailers.
The model with heat as well has been posted twice before: https://slickdeals.net/f/16729484 and https://slickdeals.net/f/16776611 , but I believe it should be the same otherwise?

I heard that the heating on portable air conditioners is not very good. Do you know if that's true with this one?

It is, just a different style. There's ones with 2 separate hoses and some that are a hose in a hose like this one.

Is this the only dual hose air conditioner costco has? The size is overkill for my use.

Sooooo many deals all winter. If you're buying this, this early in the season for basically full price you must not surf SDs enough. I see no deal here.

It's not a "flaw"...it is how heat pumps work. They pump heat (in your example) from outside to inside. Very cold means = no mucho heat to pump.

Some modern inverter compressors WITH inverter fans do a much better job verses your normal 100% on or completely off compressor or budget inverter unit with just an inverter compressor but they still hit a wall where they cannot 'recover' enough heat. Darn flawed physics Wink

You are also risking damaging the unit doing that or at least turning it into a block of ice. There is a reason the unit was set to lock out at a certain temp (also controls defrost as well). But that limit might be too conservative for certain applications. If your climate is on the borderline it might be fine. Just don't pitch a fit when the unit dies after 1-2 winters.

that's the definition of Not a Slick Deal. Not being able to find a lower price doesn't mean the price you found is good...

How did it make front page?

Bought something similar. Doesn't work that well. Still sucks in hot. Air from the cracks of the window or outside of the room

At least you cannot sleep while it is running.

Not nearly as loud as a traditional window unit when going full tilt. What's nice with the inverters is they can run less loud/powerful when the demand is less great. We had two of these that helped get us through 2022 when our up to 19 year old AC (compressor was only 13, coils were 19) was on its last legs in the Texas summer. Got a killer deal on here and resold for what we paid for last May. Kept a third we had picked up, and now we are the 'friends with the portable AC.' Two different folks borrowed it last summer when theirs went down, just to keep at least a living/bedroom tolerable.
