I purchased a small vacation home and there is one of these (or something like it) in two rooms for air conditioning only.

How loud are the inside and outside units?

How loud is this unit? Do you have the db reading or a video of it running? It will be placed outside of a window and I'm concerned about the amount of noise it will make.
What is this unit's COP at 32, 17 and 5 degrees? Where can I find detailed heating performance in cold climate applications?
Hi, how many watts does it actually use? How much does it pull if measured while running? You can get this info using a Kill-A-Watt meter which costs about $20. People who are off-grid will want to know this information. The numbers listed on the motor or compressor are not real numbers. They are maximum numbers which aren't good for calculating. If you tell me the DIY 12k is 20 amps 110v I will look elsewhere.
Thank you
Can I buy a 2 zone diy mrcool?
Can the Mr. Cool DIY 12K, 115 V be shipped with a 16 feet line set instead of 25'?

I want to use this in a wine room. Can I set the themerature to 55 degrees?
I have an enclosed patio that is 330 square feet in Southern California. Non-insulated roof, 9 large windows on 3 walls, 2 skylights, and non insulated walls. On different charts, it is recommended that I use a 12,000 BTU unit. Those charts obviously do not take into consideration the windows, etc I just mentioned. Would you recommend your 12k BTU 17.5 SEER MrCool DIY Ductless Heat Pump Split System - Wall Mount, or a higher BTU unit?
When could I expect to get this if I order today? I'm in Zip 01330. Your website doesn't mention where you are.
I am building a tiny house and it is 204 ft². Do you have a smaller unit like maybe 9000 BTU's with the 25' pre charged Hose line Set?
Can the 12,000 btu unit be bought in 240V?
I am installing on a wall that has wallpaper on it should I expect issues?
If I only need approx. 15 feet of DYI charged line for my installation - how do you suggest I deal with the extra 10 feet of line? Can it be hidden behind outside unit?
Do you have mutliple air handler on a single compressor system...
What unit powers the system, the condenser or the air handler? This makes a difference when determining whether major electrical wiring is necessary?
Is this unit first or second generation?
I like the product, but dont see how many watts it takes or amp draw, just curious.
How do I store the extra length of the 25 feet of plumbing? I only have 10 ft distance between units. I do not want to shorten the lines.
Does the fan always run when unit is on?
Is this refurbished unit still considered DIY? The original unit ships with vacuum in the hoses that breaks when screws on. Or does this unit require pulling a vaccuum and charging on installation.
One more question, thank you! What would recommend as the best location for one of these units for what will become a four-season room, which is currently a screened in porch with a roof, and two and a half walls. I realize it works best up high, with the proper clearance, but which wall would be the best, and I can design it to be any one of them, with the framing, etc. as needed. Would it work best on the wall furthest from the house, or can it be used on one of the side walls and still be efficient? Thank you!
Once connected, can it be disconnect and moved in the future?
Do you have any scratch or dent units?
Will the 12k BTU 17.5 SEER MrCool DIY Ductless Heat Pump Split System work at below 0 degree weather? I understand that the lower the outside temperature, the less efficient it is. But at below 0 degree outside temperature, will it just quit working? Thanks.
