This bundle is so easy to install, anyone can do it without any special training or tools. The included DIYPRO cable provides excellent mechanical protection without the need for an electrical conduit. You can feel confident in your purchase with the industry's only lifetime warranty, as well as a 7-year compressor warranty and 5-year parts warranty. This unit boasts a 20.5 SEER, thanks in part to the variable speed DC inverter which keeps the compressor working most efficiently. With many different modes to choose from to customize your heating and cooling experience, you have different options to control the unit as well. Use the remote, your SmartHVAC app or your Alexa or Google Assistant. The LED display located on the front panel of each cassette keeps you up to date on the status of your unit. This is a great option for replacing older, bulkier, less efficient heating and cooling systems. Color: White.
