This MRCOOL DIY 5th Gen 4-Zone ductless mini-split system pairs a 55,000 BTU outdoor condenser with 18K+9K+9K+9K BTU ceiling cassette indoor air handlers, and is designed for do-it-yourself installation without hiring an HVAC professional.
Highlights
-
Tool-free refrigerant connections — each air handler connects to the condenser with a pre-charged MRCOOL DIY Quick Connect line set filled with R-454B refrigerant, so there's no vacuuming, evacuation, or refrigerant charging required during installation.
-
Rated efficiency — this system is rated 22 SEER2 and 10.6 HSPF2-4.
-
Smart controls — each zone can be managed with the included wireless remote, the MRCOOL SmartHVAC app (iOS and Android), or hands-free through Amazon Alexa and Google Assistant.
-
Low-profile ceiling cassette design — each indoor unit fits flush between 16" ceiling joists (including pre-manufactured I-joists) instead of taking up wall space.
-
Easy filter access — the Elevation function lowers the filter panel for convenient cleaning and maintenance, and advanced filtration helps improve indoor air quality.
-
Quiet, two-stage operation — a two-stage DC motor with swing technology delivers quiet, even airflow across each room.

Details
Avermont Direct is an authorized MRCOOL dealer. This 4-zone ceiling cassette system is backed by a 5-year parts warranty and a 7-year compressor warranty from MRCOOL, with a Limited Lifetime Replacement warranty available to customers who enroll in the MRCOOL Care Program. It's a fit for homeowners who want to condition multiple rooms from a single outdoor condenser without opening walls for ductwork. Note: this condenser is rated for up to 6 zones and approximately 2,290 sq. ft. of total capacity per MRCOOL; this listing is configured as a 4-zone system with the 18K+9K+9K+9K BTU indoor units above, and it is normal for a multi-zone MRCOOL condenser's rated capacity not to exactly equal the sum of the individual indoor unit ratings.
