Is Mr cool considered low end (split sys) by pros?

[machsnell]

I am needing to replace my heat pump amd I noticed that Mr cool has a "hyperheat" type split system unit.

Pros seem to go with Goodman or carrier etc. I am just wondering what the pros say about Mr cool?

80 percent efficient to -4 degrees on a split system seems too good to be true but Mitsubishi and others do it on mini splits so why is it so impossible to imagine on a split system?


Would love advice from the pros.

Many will probably say they are low quality stuff because they dont work with them.

The truth is they are made by Midea which is a large, reputable company and I would definitely trust a *properly installed* system from them, which in many case could outperform more expensive systems from “big names”.

I don't see how they could be considered low end. They are made of quality materials. One user on this forum ripped one apart with pictures of the components. I have 2 and soon to be 3 in AZ.
The 2 in production now cool awesome in the hot AZ sun

I am glad to hear that.

Maybe its the gimmicky name or that they aren't one of the mainstream names.

I am unsure how I feel about the claims of heating at 80 percent down to -4 degrees.

Aren't most standard heat pumps only good to mid 30s and they drop off?

IMO -- the Mitsubishi mini-split units are nicer with better controls. It's a question of what fits the need. The best hyper heats have full output at very low temps .. have to look at the specification for each model

Goodman for years sold only very basic stuff and they would sell it to anybody ... so every hack used Goodman. The stuff was bare bones -- nothing really wrong with it. It's a Chevy Buick ,,, I spent a bit more and went with the Carrier utility line when I did my rentals (they are quieter)

Today Goodman is part of Daikin -- they had bought Amana prior to being bought ... so the better Goodman is Amana. It's middle of the road stuff ... the top Amana actually looks like a decent unit.

Carrier sells a more advanced product in the upper end of the line.

"Old School !" This is common for "central" heat pumps and some low end mini-split heat pumps.

The better quality mini-split heat pumps will "make heat" below zero F.

Check the Mr. Cool website. They sell several different "levels" of mini-splits. High end are for "commercial" installation.

I understand on mini splits but they have a split system that claims heating efficiently below zero.

I dont see anyone else with a split system advertising they can do that.

The Mr. Cool split system -- is the air handler model. They make a DIY version of it ....it's new. (for them)

Mitsubishi has made a conventional looking air handler for years .... it uses a conventional type asian designed outdoor compressor with the heat exchanger mounted in a conventional case to be fitted to a USA type ducted system. It allows for one compressor to do various configurations ... two ducted system in one house .... or a combination of the ducted and wall. The typical ducted mini-split was a low static design .... although they now make models that can have more extensive ductwork. This split looking model has a conventional case with blower capable of being used in a fully ducted house. It's still a mini and the system is using a mini heat exchanger ... vs an evaporator w/ metering device

Also -- There are many USA split systems that have low temp heat pumps. My carrier units can operate at 0 with full output.

410a mini-splits were introduced to the states in '06. The old R22 units didn't heat worth a damn, like the split HP's. Suddenly mini-splits made sense for heating in the northern markets. Around '10 the Hyper-heating models were introduced by Mitsu and other manuf followed. The American equipment manuf who knew this technology was out there did what they frequently do and ignored it and have gotten theirs asses kicked for it
Whichever brand you go for, make sure you completely understand the specs on the sizes, you are looking at. I have Fujitsu's. I just downloaded their current catalog, and I would suggest you look at it for comparison sake. It is like reading War and Peace, but there are multiple models with different feature sets in the smaller sizes. Some heat to 5* and others -20-30f. Know what you are buying. In our area of the foothills it very rarely gets into the teens so I use the 5* spec units.
Justin, I thought Mr Cool was made by Mitsu. Did not know Medea was involved. Yeltdog, I think the Carrier units are Toshiba's.

I love my Mr. Cool DIY 24k, it's amazing. I installed it myself last October. The thermostat was bad from the factory, so it froze up the condenser (wasn't tripping the unit to go into defrost mode). A very quick call to Mr. Cool and I had a new thermostat shipped out that same day. A quick 5-min diagnostic and 5-min install got it back up and running a few days later. I couldn't be happier with it, considering I paid $1,500 all-in. It's quiet, powerful, and hasn't skipped a beat.

My heat pump will "make heat" too, but when those strips come on, the electric meter's disk is spinning like a Dremel too. It spins so fast I can hear the quarters exiting from my wallet.

Fortunately in Eastern NC, I've never seen a zero temp. A few RARE single digits, but that's it.

mini splits don't have back up resistance heat

I don't know who makes the Carrier branded mini-split. Carrier does use a Toshiba rotary compressor in one of the regular lines .... I just installed a 3T 5 speed in my new house. Great heat pump. Toshiba -- has a long track record making mini compressors -- they at one time made all the Mitsubishi compressors. For me there was no reason to not use the Mitsubishi mini-splits -- the major us brands are all around the same cost. Trane has some agreement as well ... All the US majors are going to have to move into this ...either a partner or rebrand a quality unit.

The split systems -- that use a mini type heat exchanger are interesting especially on a house with an up and down where you can run both with one compressor ... even add an odd head someplace. There is no benefit with a typical where a conventional will work. Except the new Mr. Cool DIY -- they make a conventional air handler -- so if you want to do a conventional duct system in a garage ... this is now possible

I've been told the carrier/Bryant branded units are made by medea, our Bryant wholesaler was selling Daikin but now has an agreement to only sell the Bryant branded equipment.

As far as mr cool being cheap or not I don't know, it's not available at any of our wholesalers so it's not something we would use or install ( and we won't use customer supplied equipment as that never ends well).

Years ago I was told that all the oil dealers got Bryant and non-oil dealers Carrier. I don't know if that was true .. but, both of my oil dealers years ago sold Bryant. I used them when I switched to gas and for years after .. the one had a metal shop and did incredible work. Both bought out by a big player in the oil business.

I used to get a kick out of the box having both the Bryant and Carrier badge inside.

Both the local Carrier dealers sold Amana as a value line. Mitsubishi as the top mini and Daikin as the more value Mini (although not a huge savings). I wonder if Carrier is putting the squeeze on ?

I have been happy with Carrier products for a long time. I don't love the new case design or construction ... I hear soem rust ..my oldest is past 5 now and fine. But I wax it
