Ductless Mini-splits for 5 Unit Multifamily Cost

[Camden Brown]

Hi,

I recently purchased a 5 unit multi-family home in Massachusetts that is heated by one, very outdated, boiler. To separate utilities, I had the option to go electric (costly for tenants), put in 5 furnaces, use a RUBS system, or try mini-splits. I have heard a lot of great things about mini-splits and there efficiency. However, I have heard they are costly to install and can be troublesome in a New England climate. Has anyone separated units with mini-splits? Has anyone had them in NE or a similar climate? Does anyone know what a rough estimate of this project would be? Any helps is appreciated. Scope of project is listed below:

Project:

I would need one multi zone (3-4 zones) mini split in each unit in a multi family home. The home is 5,300 sq ft with each unit being approximately 1,000 sq ft. The property has 5 units (2 first, 2 second, 1 third). Each unit would need its own outdoor condenser. I would like to go with the LG units because they seem to be the best rated for multi zones.

Thanks in advance!
