    LONG DESCRIPTION
    Our new 5th Generation MRCOOL® DIY® 55k BTU Multi-Zone Ductless Mini-Split Condenser is one of the most efficient and innovative units in the industry, and we’re excited to finally share it with you! On top of saving time and money because you won’t need an HVAC professional, this system will give you a good sense of accomplishment because you’ll have installed it yourself! The whole family will be able to enjoy the comfort of this condenser, because it can heat and cool up to 6 different spaces that equal up to 2290 sq. ft., giving you the ability to heat and cool an entire home to your exact specifications using a single MRCOOL® system. The system’s patented pre-charged Quick-Connect® line sets essentially fast-forward the installation of this system, enabling you to skip the evacuation and charging steps and simplifying the entire process. We utilize new R-454B refrigerant in these line sets, which is a much more environmentally friendly and efficient choice. Features like these assist this unit in achieving its impressive SEER2 of 22, and its HSPF2-4 of 10.6, both of which signify that this system will help you save money throughout the entire time you use it. These line sets are sold separately. Once you install this condenser, you’ll be met with a variety of features to help you control your comfort. One of these features is the Smart HVAC app, available on Apple and Android, that allows you to operate your system from the convenience of your phone. Set schedules, manage different modes, monitor energy consumption, and more all without having to leave the couch! You can also set up voice control through Amazon Alexa or Google Home, meaning you can control your comfort without moving a finger. This system ensures you’ll be enjoying ultimate convenience and superior comfort. The warranty for this unit is one of the best in the industry, and we’re proud to have your back. You can enjoy the peace of mind of a 5 year parts warranty, a 7 year compressor warranty, and, once you enroll in the MRCOOL® Care Program, a Limited Lifetime Replacement warranty. If you need perfect comfort but don’t want to break the bank, this MRCOOL® DIY® condenser is your answer!
