Midea Duo review


Power consumption reports: 280-330 watts at a steady state when keeping a room cool. One reviewer said his watt meter registered 200 watts but that sounds low. Smaller room maybe. 2 others state 280-320 watts and 280-330 watts.
Not really sure that’s an accurate number - mine runs the full 1500+ watts into my ductwork, but I’m sure it assumes it needs cooling 100% of the time.

The portable is NOT a U in different form factor. Doesn’t have an Eco model and uses considerably more power. It’s a good unit, just not AS good as a U. I now have 2 U’s and the ‘portable’, but rarely use the portable and target run the U’s.

As a matter of fact, it feels a bit stuffy in the dining room… (beep! Bzzzzz ahhhhh)

Here’s a power snapshot of it running - baseline is a 150w server. The power up/down happens - not sure why it cycles like that.

Is that the portable (duo)? My was runing at about 600 watts from memory. After the room had cooled.

Hopefully those numbers aren't too far off. 2 different reports and 2 different watt meters. One said 280-320 watts. Another said 280-330 watts. That is on low settings after getting temperatures down, at a steady state and in a bedroom.

I will be buying this air conditioner and will add my findings.

We have 3 of these Duos we got at a retail return auction. I had no idea that these would end up being my primary cooling system for the first floor of our home, instead of our 3.5 ton AC unit. I connected these to a 6500EX, my batteries, and some panels I set out in the yard. They work well, and we enjoy the control the app gives us.

I'd rate them a 7.5/10, with the biggest issue being the hoses. I'm not sure what they can do to improve the design, but it limits placement of the unit. For example, I have this unit connected to a slider window, and can turn it about 45 degrees. Doing this puts a little twisting strain on the hose so I didn't want to force it too much, but there's just not enough flexibility in the hose for my taste. That's really my only complaint.

Whats the savings been on your power bill?

Significant, though I can't easily quantify it.

Last year during this time we had a single speed pool pump, and kept our entire house at ~77 degrees the entire month using 2 3.5 ton AC units for a 3300 sq ft house. Our power bill was about $542 in the hottest month of LV summer heat last year.

This year, we rarely run either 3.5 ton unit. We've allowed our upstairs to warm up to over 95 degrees during the day, and we spend our days downstairs where it's cooler due to our little off grid setup with the Mideas. Our bedroom is upstairs, and when we go to bed, we fire up 2 Midea u shaped inverter window ACs, one 10k and one 8k (it's a large area) that runs on energy from the utility. We also have a variable speed pool pump now.

So, overall, we've been more disciplined about not wasting energy cooling the entire home, and upgraded to a more efficient pool pump We've easily cut usage from the utility by 60-70%. Our daily usage was around $17.45 a day, and this year it's right around $6-$7 a day.

We run 4 window units in 3 buildings.
We started out with conventional window units and ended up switching those out one at a time to the inverter type window units.
In our main building where we use for a den , kitchen and sleeping quarters we keep 2, 8k units on 68 during summer months.
The other building is 14x30 and we use a 10k btu unit in there on 70.
the third building is a 12x16 and is basically a kennel for our rescue dogs and it has a 6k btu in it set on 70.
We are averaging $9.50 a day. When we had conventional window units it was around $12 a day. On days we do laundry add another $3.
We cut a few $ a month off power bill by going to a Rheem heat pump water heater. Plus got a $650 local rebate and the fed tax credits up to $2000.

We are sorta in limbo as we are planning to build on some property I have about a hour away. I already have 2 EG4 hybrid solar mini splits ready for that build. I would put them in here at her place but it just doesnt get enough sunlight since its heavily wooded.
if it wasnt for that id already have them in.

Hello LVQuack, I want to install one of these in my van build. Is there a way to permanently install new ducting to replace the supplied flexible one? This would eliminate most of the issues I read about these units.

Thanks

Steve
