Replacing current steam heating system with a mini split system in 3 family building
I recently purchased a condo in a 3-family building and along with the other homeowners, have been trying to figure out what the best heating option would be to replace our current (~15 year old) steam heating system. We have talked to several HVAC professionals who for the most part have suggested we remove the current system and install about 5 mini split units per condo. The suggested condensing unit would be a 42,000 BTU one. We live in Massachusetts so we do experience some very cold winters. Has anyone gone through a similar situation? What do you recommend?
Also, what are the findings in regards to cost efficiency after installation?
Thanks in advance for any advice!
