High Efficiency Do-It-Yourself

A MRCOOL DIY Series heat pump is the only ductless mini-split system on the market explicitly designed for amateur installation. You don’t need special tools or training to install this high efficiency heat pump. The line-sets are precharged with R410A refrigerant, the quick hook-up electrical connections, and the quality engineering mean just about anyone can install a MRCOOL DIY in their home with no problem at all in only a few short hours. If you want great air comfort without paying an arm and a leg for installation, you want an easy-to-use MRCOOL DIY Series ductless heat pump.

MRCOOL DIY 2nd Generation Features:

  • Two way draining connections further simplify installation and add flexibility.
  • MRCOOL DIY temperature compensation technology help keeps you comfortable in any weather conditions
  • Unlike any other ductless heat pump on the market, the MRCOOL DIY Series is specifically designed for easy, simple installation
  • Refrigerant leakage detection ensures your system remains operating efficiently without degradation due to undetected corrosion
  • Most people can’t do their own electrical work, and that’s why the quick electrical connections on the MRCOOL DIY are a feature many will appreciate
  • One of the most difficult aspects of typical heat pump installation is dealing with the refrigerant inside the coils. The MRCOOL DIY Series comes with precharged linesets alleviating one major obstacle to amateur installation in a single stroke.
  • Wireless remote included for convenient control
  • WifFi functionality enables you to control the unit with a smartphone or other device 
  • You can install this innovative ductless system without special tools, equipment, or training.
  • The system constantly monitors interior air temperature in order to deliver the maximum possible comfort.
  • Precharged 25' Quick Connect Line sets. These unique line sets are a cinch to get working. You’ll probably do it in less than 15 minutes.
  • We made Sleep Mode easy to program to save money, and let you sleep a little easier.
  • Power outage? Don’t worry, the MRCOOL DIY auto restart will have the unit running again in no time at all.
  • Live on the coast? Don’t worry, the condenser is built to resist long term corrosion.
  • When the MRCOOL DIY detects low coolant an alarm will sound to alert you to the problem. This will prevent damage to the compressor while you maintain high air comfort.
  • Horizontal louver will automatically move to the same position as you set last time the unit was turned on.

I am very pleased so far with this product and the support I have received from the manufacturer.

George Bradford
It works

I had ordered the 12000 btu. system. So far it has been working just fine. Due to the size of my shop I wish I had ordered the 18000 btu.
As far as a diy goes it was not that hard at all.
Of course if they had provided a little more detailed info about electrical hookup would have been nice.
For money involved and DIY hookup you just can't beat this system.
