MRCOOL DIY 5th Generation Multi-Zone Mini Split Condenser, 230V

MRCOOL DIY 5th Generation Mini-Split Condenser 230v Take control of your entire home's climate with the 5th Generation MRCOOL DIY Multi-Zone Condenser, now enhanced with R454B refrigerant. This eco-friendly innovation boosts energy efficiency, reduces greenhouse gas emissions, and offers a lower Global Warming Potential (GWP), making it a smart choice for homeowners seeking an environmentally conscious climate solution. Available in 5 flexible sizing options from 18,000 BTU to 55,000 BTU, this innovative system supports 3 to 6 air handler zones, delivering powerful, reliable cooling and heating without requiring professional installation or special tools. The DIY Series Multi-Zone Condenser is engineered to pair seamlessly with compatible MRCOOL DIY air handlers, designed with true DIY installation in mind to eliminate expensive service calls while maintaining premium multi-zone performance. The brand new 5th Generation MRCOOL DIY Multi-Zone Ductless Mini-Split Condenser is the right choice if you need immediate, effective comfort that won’t break the bank! This system, which can be installed without the assistance of an HVAC professional, is one of the most efficient and innovative HVAC options on the market. Our DIY Mini-Splits are able to forgo the evacuation and charging process because our patented Quick Connect line sets are pre-charged with R-454B refrigerant, a more efficient and eco-friendly refrigerant than R-410A, which we have previously used. These line sets are sold separately. This unit achieves a SEER2 of 23 and an HSPF2-4 of 9.9. These fittings make installation an incredibly safe and simple process, allowing you to save a lot of time and money. There are a variety of features to explore once the system is up and running. One of them is the ability to integrate your system with the SmartHVAC app, allowing you to control your comfort with the touch of a button. You can even go a step further and link your Amazon Alexa or Google home for touchless operation. With the app, you can set each zone’s temperature, set schedules for each unit, monitor your system’s energy usage, and more. There are even more features to explore that will help you customize your comfort to be exactly what you want. We’ve got your back in the unlikely event that your system malfunctions. Your system will come with a 5 year parts warranty and a 7 year compressor warranty, and if you enroll in the MRCOOL Care Program, you’ll be able to enjoy the Limited Lifetime Replacement warranty!
