Spotlight: MrCool DIY Ductless Mini-Split Heat Pump

Our latest MRCOOL DIY Ductless Mini-Split sales campaign started a few weeks ago, which means you probably saw our ads on Facebook or YouTube! Which means you might have found your way to our website, Ingram's Water & Air Equipment, with questions. What is a MRCOOL DIY Ductless Mini-Split? What is a heat pump? Are these units really DIY? Can I install it myself? Will the warranty allow for that?

Don't worry, we can answer all your questions.

What Is A MrCool DIY Ductless Mini-Split?

A MRCOOL DIY Ductless Mini-Split Heat Pump is an energy efficient, easy-to-install HVAC system. It consists of an interior air handler and an outside condenser. The air handler hangs easily on virtually any wall. The condenser is relatively lightweight with a compact footprint. Together they can deliver the air comfort you want to virtually any room in your home.

Will The MrCool DIY Mini-Split Heat & Cool?

Yes, every MRCOOL DIY Ductless Mini-Split is a heat pump. That means it can function like an air conditioner to provide cooling, then reverse cycle when needed to generate heat.

How Do I Hookup The Electrical?

The interior air handler portion of the MRCOOL DIY Ductless Mini-Split will be wired to the outside condenser. The outside condenser must in turn be wired to a disconnect box positioned somewhere on the exterior of your home. This kind of service will be simple for any electrician to perform.

Do I Have To Worry About Refrigerant?

Not at all! The MRCOOL DIY Ductless Mini-Split uses eco-safe R410A refrigerant. MRCOOL charges each system with this refrigerant at the factory. You won't have to add anything during installation. Best of all, the refrigerant lines use special "No-Vac" connectors that plug in easily. This prevents contamination from outside air and seals in the refrigerant.

What Do I Do With Excess Refrigerant Line?

Depending on your installation of the MRCOOL DIY Ductless Mini-Split, you may have excess refrigerant line left over between the condenser and the air handler. You can coil this neatly and store it behind and/or near the condenser.

    This system is great and is fairly easy to install. I recommend getting the line set cover for the outside wall.

    Does the power line for the head unit get wrapped up in the Same bundle as the copper and condensation drain hose?

    What is the coldest outside temperature that a Mr Cool split system can still generate heat in the Winter? We're up in Michigan!

    The DIY is AHRI rated down to 17 degrees. However, for a very cold climate, you might be better served by a MRCOOL Hyper Heat.

    Can these be recharged after a few years.

    Yes, any qualified technician should be able to properly charge a mini-split.
