Made in China Gree could be considered a "major brand", but not necessarily a first tier vendor with local technical support in every US region. Gree is the largest manufacturer of this type of equipment in China, with many other HVAC equipment companies getting components or complete systems manufactured by Gree.

I can't recall ever seeing a Midea in my neighborhood, but plenty of Mitsubishi, Fujitsu, LG, the occasional Daikin or Samsung. The rest are pretty rare (even Gree) in my area. I've noted several 1-off installations of a number of lesser known Chinese vendors, just not Midea.

Anon3 appears to know more about them than most, probably because Anon3 probably works for Midea America in one of their sales offices (I'm guessing the NJ sales office). On the Midea (China) home website there are no authorized dealers listed in either north or south America, but they have a dealer in Warsaw Poland, and another in Phnom Penh, Cambodia, none in the middle east or Africa.

They may have a market presence somewhere in the world outside of China, but "major brand" would be a "major stretch", at least as far as the US market goes. ( At least so far... ) It's not clear what market share they have for their HVAC equipment or appliances in China, but they do manufacture a wide range of home-appliance type products, not just mini-splits.

In the US there is far more support for the Japanese & Korean mini-split vendors (even if some of their components may be sourced from Chinese or southeast Asian subcontractors. Of the Japanese vendors Daikin is the world's largest manufacturer of variable refrigerant HVAC equipment, but Mitsubishi & Fujitsu seem to have larger market share and more local support in the US. LG & Samsung are very competitive within Korea, but LG has a much bigger presence in the US.

A little late to this party but I know my Blue Ridge mini split was made by Media. The manual I have for it is a PDF that actually shows a Midea outdoor unit in the file. It is identical to the unit I purchased except for the label that says Blue Ridge. Here's what I can tell you about it.

We bought a multi head system that will handle up to 4 head units. We have 2 head units connected to it. It was installed in November of 2018 and it's now March of 2019. We kept getting P6 error codes showing up on the indoor units. They would last for about 10 seconds and then go away. Ultimately this past weekend the system quit working. I had a good technician come check it out. The problem was a bad pressure switch. Alpine will give me a new switch. I looked it up in the parts manual and its $3 and change for the part

The down side is the switch is brazed in. So, to replace it requires the entire system to be drained down, old switch removed, new switch brazed in, system leak and pressure checked and lastly the correct, weighed amount of R410 added. THIS IS NOT GOING TO BE CHEAP TO DO AND BLUE RIDGE WILL NOT COVER ANY OF THE LABOR OR r410.

Before you buy a mini split from the Internet you may want to price a unit through a company that sells, installs and services them. You may pay a little more up front but you would also likely be covered via warranty for the labor, parts & material should something like this happen to you

Sorry to hear that BlueRidge isn't providing better relief & warranty support after selling you a defective unit. It's almost the opposite of how Mitsubishi treated one of my relatives in WA after her 6-7 year old FE18 got fried by a major powerline fault that was in no way Mitsubishi's responsibility.

I do have some updated and interesting information though. Today I called Midea support and explained the situation. The guy was very nice and sympathetic that I spoke to. He opened a case for me and our tech is to call him directly and run a few tests while they are on the phone. Midea may do something to compensate us financially. I will post back the results.

I should also note the performance during severe cold. We had temps down to minus 9 degrees F. and the unit produced plenty of heat. People had told us that it would not provide heat at those low temps but they were wrong.

For the DIY guys. On all the mini splits I've seen the terminal blocks are horrible and if you rely on the factory flares for good connections you are pushing your luck. I see some of the units now, Mr. Cool to be specific, has the better type of fittings for the line set connections.

ALSO VERY IMPORTANT.... DO NOT USE NYLOG on the fittings. You will see all sorts of videos where people use it. That stuff can get in the lines and cause problems such as making valves stick open or closed. Our tech informed us about that. He's installed approximately 400 Mitsubishi split systems. The guy was excellent. Only oil should be used on the threads of the line set fittings.

One last comment regarding Personal Safety. Blue Ridge support will tell you to go ahead and remove covers on the unit to get access to the LED to get the trouble code for them. What they DO NOT tell you is that there may be 500 volts DC in the system even after you turn the breaker off!!! It takes a little time for the system to discharge after you turn off the main power source. If you ask me, Alpine is playing a dangerous game with the way they provide support. WHEN IN DOUBT........call a PRO to diagnose problems.

When buying a mini split system, my advice is to skip the discounted Chinese systems and get a Mitsubishi or equivalent system from Japan through a dealer / installer that will provide at least one year of labor under warranty. It's like anything you by from China.....it's cheap for a reason.

You can not reclaim and reuse R410A refrigerant do to fractionation. It is a blended refrigerant and will not be able recovered then use over. R22 the old refrigerant was made of one part and could do that . plus anytime you reclaim refrigerant at all you will never get all of the refrigerant out of the recovery bottle. When doing leak repairs or just a simple components replacement always make sure your tech is using NEW R410A refrigerant or you could lose performance in your machine.

Also, we don't need to reclaim to begin with. We put systems in heat mode and shift the refrigerant to the air handler. Most mini splits still have an access port after the compressor. If not, then you'd have to fully recover.

Frankly, no one in my area wants to put one in, probably because they know no one wants to spend $5k for an install. I could spend more $ for a contractor Mitsu install, but it would cost 3x more than doing it myself. So even if I have no warranty, so what? I'm already way ahead.

The notion that United Technologies may eventually put Carrier completely into the hands of Midea at some point on some future giga-deal isn't out of the question. Midea is one of those multi-national corporations that makes all sorts of aquisitions and joint ventures with other established companies young & old.

I was curious about larrycav's post above that mentioned that there may be DC power still in a mini split after the circuit breaker is thrown. I spent last weekend replacing the main circuit board on my LG LMU 369HV outdoor unit, after throwing the breaker (I also pulled the outdoor breaker near the unit). I am happily alive, but I would like to know how this is possible-I presume that there is no battery in the unit???.

The DC voltage that may be present is due to the presence of large capacitors. These discharge gradually through the circuit after a/c power is removed. Exactly how long it takes is hard to estimate. When I used to work on equipment with components like this I would manually discharge the caps with a resistor, but that shouldn't be undertaken by a DIYer.

Installed 2 systems 2 years ago. Each was a 2.5 ton with 4 indoor units. Both were a DIY install and my HVAC guy comissioned (about $100 each). Both are in rental housing and both have operated flawlessly since installed....no problems. My HVAC guy said I saved about $15,000. If you have basic ability and a HVAC guy who will pressure test and balance the refridgerant to the line set lenghts.. then this is the way to go...
