This 36,000 BTU ductless heat pump split system by MRCOOL provides you with 3 wall mounted air handlers that can be used in 3 different size rooms. Each wall mounted unit is equipped with a removable air filter that can be easily cleaned by the average homeowner. Keeping a routine maintenance schedule will keep your system healthy and efficient.
