Questions

About this calculator

Why do HVAC quotes vary so much?

Equipment tier, installation quality and whether ductwork is addressed. The cheapest quote frequently excludes duct modifications the new system actually needs.

Should I replace the furnace and AC together?

Usually yes if both are near end of life. Matched systems perform to their rated efficiency, and a single installation costs less than two separate visits.
