Short answer
Before switching to a heat pump, get a proper heat-load calculation, decide whether to keep the furnace as backup, check that your ductwork suits the new system, and look up current Mass Save incentives, which have changed often. Many Central Massachusetts homes use a heat pump with a furnace backup for the coldest nights.

Sizing matters
A heat-load calculation, not the old furnace size, should set capacity.
Backup heat
Dual-fuel setups keep the furnace for very cold days; all-electric setups rely on cold-climate heat pumps.
