Overview
The MRCOOL O-HH-18-HP-230B is a ductless mini-split system from the MRCOOL Olympus Hyper Heat line. It delivers 18,000 BTU/h of cooling and heating capacity. MRCOOL rates its efficiency at 21.5 SEER2, 12.5 EER2 and 11.3 HSPF2. It uses R-410A refrigerant and runs on 208-230V single-phase power.
A ductless mini-split heats and cools a room or zone without ductwork: an outdoor condenser connects to an indoor air handler through a small wall penetration, and the inverter compressor adjusts its speed to hold temperature.
