How often should a furnace or boiler be serviced?

Once a year, before the heating season, is what most equipment makers recommend. A tune-up is also when a technician checks for carbon monoxide leaks and worn parts.

Do heat pumps work in a North Country winter?

Cold-climate heat pumps are built to keep heating in sub-zero weather, though output drops as it gets colder. Many homes here pair one with a gas or oil furnace that takes over on the coldest days (a 'dual-fuel' system).

Are there rebates for heat pumps in New York?

Yes. NYS Clean Heat pays heat pump incentives through your electric utility, usually applied for by a participating contractor. Ask the contractor whether they participate, and check current amounts on the program's site.
