Is the model rated for cold climates?

Ask for a cold-climate heat pump that keeps its capacity at low temperatures, and whether a backup heat source is recommended.

Do they test for carbon monoxide?

Any furnace repair should include a carbon monoxide and heat exchanger check, especially on units more than 15 years old.

Will they do a load calculation?

Replacement systems should be sized with a Manual J load calculation, not by matching the old unit. Oversized equipment short-cycles and wastes energy.
