The MRCOOL DIY 5th Gen Hyper Heat condenser is a single-zone outdoor heat pump built for cold climates, rated to operate at outdoor temperatures from -22°F to 122°F. It comes in 12,000 and 18,000 BTU sizes at up to 23.5 SEER2, and ships with a 25' Quick Connect line set pre-charged with R-454B and the DIYPro cable for homeowner installation.
Pair it with a 208/230V DIY 5th Gen wall air handler or OuttaSight ceiling cassette of the same capacity to heat and cool rooms of up to 550ft² or up to 800ft². That is the MRCOOL DIY 5th Gen Hyper Heat condenser.

What's Included
- MRCOOL DIY 5th Gen Hyper Heat condenser
- 25' Quick Connect pre-charged line set
- DIYPro cable
Installation
Designed for homeowner installation. The Quick Connect line set arrives pre-charged with refrigerant, so no vacuum pump, gauges or refrigerant handling is needed. Each fitting is tightened with two wrenches to the torque in MRCOOL's manual and then leak-checked. Electrical work still has to meet local code: the 230V models need a dedicated 230V circuit, and some areas require a permit or a licensed electrician for that part of the job. Check your local rules before you start.
Line sizes are 1/4" x 3/8" for the 12,000 BTU model and 1/4" x 1/2" for the 18,000 BTU model. The indoor unit (wall air handler or ceiling cassette of the same capacity) is purchased separately.

About MRCOOL
MRCOOL designs heating, cooling and water-heating equipment from its home base in Hickory, Kentucky. The range runs from DIY ductless mini-splits, built around MRCOOL's patented pre-charged Quick Connect line sets, through contractor-installed mini-splits, central split systems, packaged units and gas furnaces, to HeatWise water heaters and CoolBlade HVLS fans for warehouses and shops.
The DIY 5th Gen Hyper Heat condenser is the cold-climate member of MRCOOL's DIY 5th Gen line. It uses the same pre-charged Quick Connect installation as the standard single-zone systems, pairs with a 12,000 or 18,000 BTU DIY 5th Gen 208/230V wall air handler or OuttaSight ceiling cassette (sold separately), and is rated to run from -22°F to 122°F outdoors. For milder climates, the standard DIY 5th Gen single-zone systems cover 9,000 to 36,000 BTU.
