Key Specifications
Product Overview
The 4th Generation MRCOOL® DIY® 36K BTU 4-Zone Ductless Heat Pump offers the latest in heat pump innovations.This condenser has the ability to support up to 4 zones and when paired with select MRCOOL® air handlers, can provide a SEER efficiency rating of up to 21.5. It even has the ability to provide heat when temperatures drop down to -13°F. It features a Gold Fin® condenser coating that allows it to withstand the elements and resist corrosion. However, the most innovative feature is that it can be installed by the homeowner without the use of a certified technician. This is possible because the condenser is intended to be used with the MRCOOL® Pre-Charged Quick Connect® Line Sets. These line sets are pre-charged with R-410A refrigerant and feature quick connect connectors, which allow it to be connected using only wrenches. Because it is pre-charged, the system will not require refrigerant handling or brazing once installation is complete. Warranty coverage includes 7 years on the compressor and 5 years on parts, along with eligibility for the MRCOOL® Care. The 4th Generation MRCOOL® DIY® 36K BTU 4-Zone Ductless Heat Pump is one of the best options on the market when it comes to multi-zone comfort.

Manufacturer Warranty
Covered by MRCOOL's limited warranty. Warranty terms are set by MRCOOL and differ by product line — whether registration is required, and whether the installation has to be performed by a state-licensed HVAC contractor, is not the same across the range. In every case coverage depends on the unit being installed according to MRCOOL's instructions and all applicable codes and permits. MRCOOL's warranty document for this model is the controlling source; ask us and we'll send you the one that applies.
Professional Installation Recommended
Most HVAC equipment must be installed and connected by a licensed professional to remain safe, code-compliant, and eligible for manufacturer warranty coverage. If you're unsure about installation requirements, contact us before you order.
Make sure it is the right size, and that you have the rest of it
Most outdoor units ship alone. If you are not certain of the capacity, or of what has to go with this unit, these two will work it out with you.
