FAQs
Furnace Installation questions
Answers to questions that come up often with this service.
Furnace sizing is based on a heating load calculation that accounts for square footage, insulation, windows, and climate. Oversizing leads to short cycling and uneven heat.
Most residential furnace replacements are completed in a day, though additional venting or ductwork changes can extend the timeline.
