Furnace vs Boiler in Maui County, Hawaii
When a furnace makes sense
A furnace makes sense if your house already has ductwork, since that same ductwork can double up for air conditioning, and Maui nights rarely need more than a bit of takeoff on the chill. With winter lows only dropping to around 59°F, you are not asking much of it, so the simpler, more common setup is the easier one to live with.
When a boiler makes sense
A boiler suits a house built around radiators or in-floor pipes rather than ducts, since running that heat is about 5% cheaper here than a furnace. It makes the most sense if your home has no ductwork to begin with and never will need it for cooling either.

Furnace wins in Maui County.
In the Pacific states, 56.9% of homes heat with a furnace, so just over half already have the ductwork it needs.
If your home already has radiators or in-floor pipes instead of ductwork, a boiler still makes more sense than adding ducts for a furnace.
