Description
This MRCOOL DIY 5th Gen wall mount air handler is the 24,000 BTU indoor unit for one zone of a multi-zone system.
Highlights
- Sized for a large open area where one zone has to carry most of the load
- Mounts high on an interior wall, keeping floor space clear
- Connects to a MRCOOL DIY multi-zone condenser with a pre-charged quick-connect line set
- Takes a 3/8" x 5/8" line set, shared with the 36,000 BTU handler
- Heat pump operation, providing both cooling and heating in the zone
Details
Avermont Direct is an authorized MRCOOL dealer. Buying the air handler on its own means a multi-zone system can be sized room by room rather than taken as a fixed factory combination. It is backed by the manufacturer's warranty, and full terms are set out in the product documentation.
