Having different contractors come in each has a different idea on heating and cooling a 1000 sq ft home just north of Boston MA. I've had suggestions from gas to hyper heat mini splits and the latest being a Bosch inverter heat pump using the existing duct work. Its all becoming very confusing with each claiming their system will be the most cost effective to run
I know that to install gas or inverter is a few thousand cheaper but I'm trying to get the picture of overall yearly cost to run which no one wants to reveal.
Any help would be appreciated.
