Cost to Install Multisplit for HVAC
Just started getting back some bids for a new home we’re building in MA (Boston suburb). I’m worried because although we are shooting for “pretty good house” insulation levels, some of the builders expressed skepticism of using a mini/multi-split for HVAC. On our first bid, they indicated that a mitsubishi system would cost $88k to install, and it just sounds outlandish given my early research into the systems! Is this one of the “non-bids” that I hear about – where an HVAC contractor puts in a high price to sway you away from these systems and back towards traditional gas furnaces?
It’s a 3000 sf two story home. BeOPT and CoolCalc #s come back as likely in the 35,000 BTU heat load range (still in the process of getting an official engineering load calculation). Should I be hunting for my own HVAC installer, or have I seriously underestimated things on my end?
