This MRCOOL DIY bundle that can heat or cool 4 spaces in your home includes a 36，000 BTU condenser， two 9，000 BTU cassettes， two 12，000 BTU cassettes， 4 remotes， and 4 Wi-Fi-enabled app kits. Each of the 9，000 BTU cassettes is capable of heating or cooling a space of up to 375 sq. ft. while the 12，000 BTU cassettes can cover a space up to 500 sq. ft. Installation of this bundle is easy and requires no special tools or training， nor the assistance of an HVAC professional. The new DIYPRO cable gives your unit exceptional mechanical protection without the use of an electrical conduit. Backed by the industry's first limited lifetime warranty， this mini-split unit also totes a 7-year compressor warranty， and 5-year parts warranty. This unit has a SEER of 21.5 thanks to the variable speed DC inverter that controls the compressor from running excessively when unnecessary. You'll be able to control the many operational modes with the included remotes， the SmartHVAC app on your Apple or Android device， or use your Alexa or Google Assistant to go completely hands-free. The clear LED display keep you informed about your system from information about the set temperature to reminders to clean or replace the air filters. This is a compact， space saving option that can be a convenient replacement for older， bulkier， less efficient units.
