We removed our old furnace and AC system, all ductwork in the space above the ceilings, checked and leveled all of our existing blow-in insulation above all rooms (now that we could check it with ductwork gone), diligently sealed all old HVAC vents, installed 4 Mitsubishi mini-splits (one for each bedroom, one larger one for living areas). Upshot: minis heated rooms well in late winter; have easily kept rooms cool (low 70s to mid 70s) thus far this summer. 1600 sq ft living area; we have all the regular necessary appliances and a large freezer; last SECO bill was $135. We like the convenience of individual control of minis (e.g. closing off a spare bedroom), efficiency of minis, extra closet/storage space from absent furnace), unencumbered storage space in attic areas (no ductwork), $2K federal energy credit for minis. Not sure of the age of your HVAC system but when due for replacement consider mini-splits. We also are well familiar with heating, HVAC, oil, electricity costs from the NE and we’re glad we took my brother-in-law’s suggestions to go all in with minis. He’s a retired electrician and has six running in a large NH house. Even up in the cold NE people have done the numbers and minis can be an effective heating/cooling system (particularly down here in FL). And economical regarding use of electricity. Good luck with your research.
