The MRCOOL DIY Mini-Split 4th Gen - Multi Zone Air Conditioner and Heat Pump w/ Ceiling Cassette - Complete System is a versatile and efficient solution for multi-zone heating and cooling in your home providing greater control over your home's heating and cooling and allow you to create a more comfortable living environment.   

This complete system includes a heat pump condenser that is capable of providing both heating and cooling, as well as an air conditioner with a ceiling cassette that distributes cooled air throughout multiple zones in your home.

Some of the key features and benefits of this product include:

Easy DIY installation: The MRCOOL DIY Mini-Split 4th Gen - Multi Zone Air Conditioner and Heat Pump w/ Ceiling Cassette - Complete System is designed for easy installation, with a simple and straightforward process that can be completed by most DIYers.

The ability to install the unit between standard ceiling joists or I-joists, and the use of screws for securing it in place, makes the process even easier and more convenient to be easily installed by homeowners with its simple do-it-yourself installation process.

You no longer need to pay for an expensive professional installation service as it comes with everything you need to get started, including a quick-connect line set and an easy-to-follow instruction manual.

Low Profile Installation: The MRCOOL DIY Mini-Split 4th Gen - Multi Zone Air Conditioner and Heat Pump w/ Ceiling Cassette - Complete System  can be installed in a variety of locations without it being too prominent or taking up too much space. 

This can allow you to place the unit in a location that is most convenient or effective for heating and cooling your space. 

Versatile Fit: The versatile fit of the MRCOOL DIY Multi Zone Ceiling Cassettes means that it can be installed in a variety of different scenarios, including in new construction or as a retrofit in an existing space.

Designed to work with current and future joist standards, it can be recessed between all types of joists on a 16 inch center - including pre-manufactured I-joists.

Easy Air Filter Access: Easy air filter access means that you won't have to spend as much time and effort trying to access the air filter for cleaning or replacement.

This can be especially beneficial if you have a hard-to-reach or high-up installation location, as you won't have to use a ladder or other equipment to access the filter.

By activating the Elevation function on the remote controller (or smart controller), the filter panel will lower for easy air filter maintenance.

Multi-Zone configuration: With a multi-zone configuration, you can have separate temperature controls for each zone, allowing you to customize the temperature in different areas of your home. 

A multi-zone configuration can be more energy-efficient than a single-zone system, as it allows you to only heat or cool the areas of your home that are currently being used. 

This can help to reduce energy consumption and lower your energy bills and also works with the MRCOOL® DIY Mini Split 4th generation series of units.

Best Warranty in the Business: Lastly, MRCOOL DIY Mini-Split 4th Gen Multi-Zone  Heat Pump Condenser and Air Conditioner w/ Ceiling Cassette - Complete System offers a limited lifetime compressor warranty giving you peace of mind that your investment is protected. 

Standard 7-year compressor/5-year parts warranty, register for limited lifetime compressor warranty.
