What you're paying for
What is usually included: Diagnosis, a new contactor ($15–$60 in parts), installation and a system check, usually within an hour.
What moves the price:
- Diagnostic fee and whether it is credited toward the repair
- Replacing the capacitor at the same time, which is common and reasonable
- Two-pole versus single-pole contactors and brand-specific parts
- Emergency service rates
Part is cheap (under $100); price is mostly the service call plus a short labor block, so emergency timing and flat-rate markup move it most.

Frequently asked
Is $250 a fair price for AC contactor replacement in Montana?
Yes. $250 is right around what most homeowners in Montana pay. Anything from $60 to $484 is inside the normal range for an HVAC company; above $484 it is worth getting a second quote.
Why do quotes for the same job vary so much?
Diagnostic fee and whether it is credited toward the repair. Replacing the capacitor at the same time, which is common and reasonable. Company overhead matters too: a large company with trucks, dispatchers and a warranty department charges more than a one-person shop, and both can be honest prices.
When should I get a second quote?
Any time a quote lands above $484, or when the contractor cannot break it into parts, labor and fees. Ask for the itemized version, ask what would change the price, and confirm licensing and insurance. You can also paste the quote into the free QuoteJury checker for an instant second opinion.
