The high-wall mount models do not have an option to pull in outdoor air directly so it is circulating the air inside the room however it’s also filtering and cleaning it while at it
The best Mitsubishi mini-split feature I have seen. Thx so much!😎. Can you mount a wall unit lower on the wall, say about 3-4 feet? We have very limited wall space and the floor units are much more expensive than the basic wall mount. Our foundation is raised about 12 feet above flood stage because we are on an estuary and the floor is very chilly in the winter. I am aware there are intelligent features which might not function correctly but I was wondering if this lower configuration would have any negative effects on the building envelope…?
Sorry for such a late reply here. We have installed them lower on a wall like you mentioned and it can work but you do lose some performance. I’d suggest it being up about 6-8’ high
@@chrisparker1849 Thanks for your reply. We did install our Daikin wall unit about 4’ above the floor and found that it made our sub floor soggy. Now we have to remove the finished floor and replace a portion of the subfloor. We decided to put in a Mitsubishi floor standing unit (mounted several feet above the floor on the wall). The floor unit can be programmed to blow up or down, I believe. All these ‘issues’ with the Daikin unit happened on a raised wooden foundation, on the water, in a stick built condo, in the SC low country. The building is 1980’s so the floor might have needed attention anyway…. Falling through the subfloor is not an uncommon occurrence in local condo units of this age. Our low wall unit placement may have just hastened the inevitable. It took 5+ years of 24/7 use for the Daikin wall mounted heat hump to compromise the floor.
The thermostat is built into the unit to get the most accurate overall temperature in the room as the return air is pulled in. The remote acts just as a remote, not a temperature sensor. However they do have a brand new model of their wireless wall mount thermostat if you'd prefer the traditional thermostat on the wall and/or the ability to have the system sense the temperature from a different location than at the unit.
Good question. There are really only a few companies with a reputable mini split product. Most are junk. Mitsubishi Electric has a long standing reputation of quality products, particularly in their HVAC division. They are built to last and that's clear to anyone who's installed one and another brand. And they offer an incredible 12 year warranty on parts if purchased and installed by a trusted dealer like Command Comfort. Hope this helps
Yes they should. From the factory they should come pressure tested with nitrogen. It should be released and once system is installed and pressure tested. A vacuum should be pulled to 500 microns or below.
Are you familiar with the Mitsubishi cooling only units? I was wondering why the units have max cooling rating higher than the rated capacity, Like the 18k has a minimum of 5,800 and a max of 22,000
Yes we are familiar with those. Good question about that capacity as it can be a bit confusing. Ultimately, as I know it. The 18k rating is the nominal rating. Actual capacity always varies slightly although I'm not sure what the range can be technically. So when sizing an A/C unit, it's very important that the people doing so understand this well and don't just pick based on the nominal size rating. Now to speak to the low range on your example of down to 5,800 btu's. This is due to the variable speed compressor that allows it to operate at a very low speed setting in order to maintain room temperatures and not have to turn off and on like a standard air conditioner would. Hope this helps
Very good video..I install these but we only do wall units. At the end of my installs, I always end up explaining these units to customers
Glad it helped
Does the fan mode take air from outside or just recirculate the air in the room?

So do these units have a thermostat or does the remote work as the thermostat? Or do they just run at 70* the entire time they’re on?
The thermostat is built into the unit to get the most accurate overall temperature in the room as the return air is pulled in. The remote acts just as a remote, not a temperature sensor. However they do have a brand new model of their wireless wall mount thermostat if you'd prefer the traditional thermostat on the wall and/or the ability to have the system sense the temperature from a different location than at the unit.
Why Mitsubishi instead of other brands?

Should Mitsubishi indoor cool only wall units have a release of nitrogen when taking off caps?
Yes they should. From the factory they should come pressure tested with nitrogen. It should be released and once system is installed and pressure tested. A vacuum should be pulled to 500 microns or below.
