Angi reports a national average of $318 for furnace repair, and HomeAdvisor reports $417 for AC repair in their 2026 guides. These national figures are general budgeting references, not a quote, advertised rate, or price cap from Great Falls Heating and Air. Your repair may cost less or substantially more depending on the fault, parts, equipment access, labor, warranty coverage, and any emergency or after-hours charges. Call to confirm the diagnostic fee and what it includes, then review the price for the proposed work before approving the repair.

Start with the diagnosis. A repair may make sense if it can restore safe operation and the rest of the furnace is in reasonable condition. Repeated failures, unavailable parts, or a costly major repair can make replacement worth comparing. Age is part of the decision, along with repair history, comfort problems, warranty coverage, and the full replacement cost.
A properly selected cold-climate heat pump can provide winter heating, but the model and your home matter. Compare how much heat it delivers in cold weather with how much your house needs. Plan any backup heat around that difference. If you’re keeping a gas or propane furnace, check that the equipment and controls can work together. A low advertised operating temperature alone doesn’t tell you whether it can heat the whole house.

Possibly. It depends on your utility account, the exact equipment, and the current program rules. Our Montana HVAC rebate guide links to the official programs. Keep the full installation price in view until the incentive is confirmed.

Published offers do not guarantee availability, eligibility, approval, or payment. Before buying equipment or authorizing work, confirm current terms, funding, and any required advance approval directly with the program administrator.
