DIY 4th Generation E Star 12K to 36K BTU Heat Pump Condenser 115/230 volt 18-22 SEER with 25 foot line set – 230v / 36K BTU

MrCool DIY 4th Gen Condenser for Year-Round Climate A grow room that needs cooling in summer and heat in winter usually means two machines and two power draws. This outdoor heat pump condenser does both from one unit, in sizes from 12,000 to 36,000 BTU. A variable-speed DC inverter ramps output to match the load, so it holds a set temperature efficiently instead of cycling on and off. The 12K, 18K, and 24K models are Energy Star certified at up to 22 SEER, with the 36K rated 18 SEER2. Low-ambient cooling works down to 5 degrees, which suits a server room, greenhouse, or grow space that needs cooling all year. Gold Fin Outdoor Unit with a 25 ft Line Set A Gold Fin coating protects the coil against long-term corrosion, so the unit holds up even in coastal or humid air. Built-in leak detection sounds an alarm if refrigerant runs low, which guards the compressor before damage sets in. Each condenser ships with a pre-charged 25-foot line set, so the install stays a few hours with basic hand tools and no vacuum pump. That steady output keeps a grow room or greenhouse on target through heat waves and cold snaps, so the canopy never stalls. It reads as an outdoor unit only, so it pairs with a matching DIY 4th Gen air handler for a complete single-zone system. MrCool backs it with a limited-lifetime compressor warranty on registration, plus a 7-year replacement and 5-year parts.
