Key Specifications
Product Overview
The MRCOOL® 4th Generation DIY® 18K BTU Ductless Wall Mounted Air Handler is one of the most capable on the market. When part of a MRCOOL® DIY® system, it can reach an effective 22 SEER efficiency rating and deliver that performance to an area up to 750 sq. ft. This air handler is also very versatile because of its many different operating modes, these include, COOL, HEAT, AUTO, DRY (dehumidify), and SLEEP. It also has the ability to be controlled from anywhere using an Apple or Android smartphone with our convenient Smart HVAC app. This air handler is very compact and relatively light, so it can easily be mounted to most interior walls using the included mounting plate. The ease of installation does not stop there, as it is designed to be used along with the MRCOOL® Pre-Charged Quick Connect® Line Set. This allows the installer to easily connect the refrigerant piping, which is precharged with the correct amount of R-410A refrigerant, with the use of simple hand tools. This also means the system will not require any vacuuming once the line set is connected. The MRCOOL® DIY® 18K BTU Ductless Wall Mounted Air Handler has the performance to handle your home comfort needs.

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.
