Overview
Take full control of your home comfort with the 3rd Generation MrCool DIY 12k BTU 22 SEER Ductless Heat Pump Mini Split System. Homeowners can easily install this outdoor heat pump condenser and indoor air handler since installation requires no special tools, equipment, or training. This full heating and cooling system can be installed in just a few hours. It has a heating capacity up to 12k BTU, so it is ideal for spaces up to 500 square feet depending on your climate zone.
The key to the 3rd Generation MrCool DIY 12k BTU 22 SEER Ductless Heat Pump Mini Split System's easy installation capability is the pre-charged Quick Connect line set — MrCool's cutting-edge technology that makes setup safe, simple, and cost effective. The line set uses the environmentally friendly, and chlorine-free refrigerant R-410A, which is an alternative to old refrigerant that won't damage the ozone layer.
But what if your new MrCool ductless mini split runs low on that same R-410A refrigerant? Not to worry, since an alert will appear on your indoor unit. It lets you know so you can address issues before they cause costly damage. Should a power outage occur, the 3rd Generation MrCool DIY 12k BTU 22 SEER Ductless Heat Pump Mini Split System will auto start once power returns, making your home comfortable as soon as possible.
That's not all. The MrCool indoor wall unit also displays alerts when the air handler filter needs cleaning or replacement. With this feature, you can trust the air you breathe is always fresh! The cleaning alert displays after 240 hours of operation and filter replacement is suggested after nearly 3,000 hours of run time.
The outdoor MrCool mini split condenser can be anchored to the ground or attached to a wall with a bracket. The outdoor unit is 31.5 inches wide, 21.8 inches tall, and 13.1 inches deep, while the mounting dimensions are 20.24 inches wide by 13.39 inches deep.
The 3rd Generation MrCool DIY 12k BTU 22 SEER Ductless Heat Pump Mini Split System can handle a wide range of outdoor temperatures, as low as 5°F and as high as 122°F. Plus, with the auto, sleep, and timer modes you can customize your system to run to your preferences and keep your HVAC running efficiently; saving money.
When the 3rd Generation MrCool DIY mini split is in COOL, DRY, or AUTO mode, an anti-mildew function activates and keeps a low fan running for about 10 minutes with low airflow to dry up condensation that can cause mildew growth. The unit also runs quietly and smoothly so you can trust it will work without any noisy interruptions while it keeps your air clean and at just the right temperature.
Want exacting control? You can control the 3rd Generation MrCool DIY 12k BTU 22 SEER Ductless Heat Pump Mini Split System wirelessly with the included remote, Google Assistant, Amazon Alexa, or an app from your Apple or Android device. Get custom performance from your ductless MrCool mini split system with the FOLLOW ME feature, an option for your maximum comfort that will track the air temperature around you as long as you keep the remote nearby.

Q & A
I have an older house that has 60amp fuses in the breaker box. It is 120 V. I was wondering how much amperage these units would require?
Is it just wires that you need to connect to an electrical whip and then to a standard 120v 3-prong outlet, but on it's own breaker? Or is it like a 30A RV type plug? Or is it not even a plug in thing and it has to be wired directly to an electrical box on the side of the house? I'm wanting to wire it to my enclosed trailer, so I can connect it easily to either my house, or to my generator, but not understanding what the plug requirements are? (I would have an electrician install, but don't understand what to tell them on what I need). Thank you.
Can a hvac man do it if I can't?
Thanks!

I do not want the WiFi feature, keeping it simple and I really do not think I will want it. Can I purchase the unit without?
Mr. Cool really does need to offer units with shorter line-sets for installations directly outside of the air handler. Coiling the extra line-set up behind the outside unit is unsightly & minimizes airflow. My only complaints.
Thanks again!
Please advise. Thanks!
Any ideas? Thanks. Also, what is the cost of a pump incase the water needs to be pumped out of the drain line?
Thank you.
Thanks
I have a gas hydronic boiler, 78% efficient. Electric rates here are $.23/kWh. Would using the heat pump save any money?
Thank you!
I was sent a proposal, but Jacob the sales rep, put on two products I don't need. When click through to my dashboard to edit proposal, it says the edit option is not available.
Any sugestions?
Thanks!!
Thanks.
