Mr. Slim Split-zoning Systems: M-Series Heat Pump

Mr. Slim Split-zoning Systems

Small Size, Big Performance
While all of our Mr. Slim units are compact and lightweight, M-Series heat pumps were designed specifically to provide high performance heating and cooling for tight spaces. But don’t be fooled. The powerful M-Series delivers plenty of year-round comfort. And unlike window units, Mr. Slim’s small size, color, and mounting position make it blend in well.

No Ductwork Needed
Mr. Slim systems require no ductwork. There’s only a small, three-inch opening connecting the indoor and outdoor units. These features result in easy installation, less mess, and a better looking home.

Standard pricing for an installed MS-A09WA, cooling-only, model should start around $2,390. A number of factors contribute to the actual installed cost, such as line length and exterior wall material.

Please ask a Diamond Dealer to survey your home for an accurate job cost.

Don't forget to ask about a Buy-Now Pay-Later plan.
