Great Falls homeowner guide · Updated October 16, 2026
What affects the price?
Two estimates can cover different materials, preparation and repair allowances. Ask each business to describe the scope in writing.
- Equipment capacity, fuel type and efficiency rating
- Whether ducts, venting or controls also need updating
- Accessibility, old-unit removal and installation scope
Planning for your Great Falls home
Montana winters make sizing, safe venting and reliable installation especially important. The cheapest equipment quote is not always the best fit.
Questions to ask before hiring
- How did you size the furnace for this home?
- Are venting, thermostat, duct modifications and removal included?
- What are the labor and manufacturer warranty terms?
- Can you provide a written scope, applicable insurance information and an expected schedule?
Compare the same work
Include equipment or material specifications, labor, removal, site protection, cleanup and any permit responsibilities in each estimate. Ask how changes and unexpected repairs are handled. Confirm payment and warranty terms before accepting a bid.
