The MRCOOL DIY series heat pump is the only ductless mini-split system on the market explicitly designed for amateur installation. You do not need any special tools or training to install this high efficiency heat pump. The line sets are precharged with R410A refrigerant with quick hook-up electrical connections and allows just about anyone to install a MRCOOL DIY mini-split system in their home 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 system.

  • 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.

  • 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.
  • Two way draining connections further simplify installation and add flexibility.
  • Unlike any other ductless heat pump on the market, the MRCOOL DIY series mini-split system is specifically designed for easy, simple installation.
  • Most people can’t do their own electrical work, and that’s why the quick electrical connections on the MRCOOL DIY is a feature many will appreciate.
  • MRCOOL DIY temperature compensation technology helps keep you comfortable in any weather conditions.
  • Refrigerant leakage detection ensures your system remains operating efficiently without degradation due to undetected corrosion.

Excellent unit.
I bought this unit to install in my island home. The cost to bring a tech over is expensive to charge the a/c unit.
This unit is great and no tech is needed. I installed in a weekend and it works amazing! Heat and A/C work great!
