About this product
Introducing the 4th Generation MRCOOL® DIY® 27K BTU 3-Zone Ductless Heat Pump Condenser which is one of the most capable heat pumps on the market. When this 3-zone condenser is matched with select MRCOOL® air handlers, it can produce a highly effective 22 SEER efficiency rating. It can also provide heating performance all the way down to -13°F. With its Gold Fin® condenser coating, it is sure to withstand the seasons, enduring especially well in coastal or humid climates. The cornerstone of this heat pump is its ability to be a Do-It-Yourself project. When used with MRCOOL’s® patented Pre-Charged Quick Connect® Line Set, the refrigerant piping can be connected with simple hand tools and does not require the services of a certified technician. It comes pre-charged with the correct amount of R-410A refrigerant so, once installed, it does not require vacuuming. Built for reliability, the MRCOOL® DIY® 27K system is protected by a 7-year compressor warranty and 5-year parts coverage, with MRCOOL® Care Program eligibility.
