wow, we paid $16k for 4 indoor units/1 outdoor unit (we can add 1 more indoor unit in case we re-do the basement). $2k for the heat pump hot water heater. $1k to have the oil tank removed. $19k total. for the mini split/water heater we got a 1% loan from the state.

we're in new england and got the mitsubishi hyper heats. this was all pre-covid but wow that is an expensive quote.
