Frequently asked
Is $1,400 a fair price for evaporator coil replacement in Idaho?
Yes. $1,400 is right around what most homeowners in Idaho pay. Anything from $228 to $2,805 is inside the normal range for an HVAC company; above $2,805 it is worth getting a second quote.
Why do quotes for the same job vary so much?
System size and refrigerant type; matching a coil to an older R-22 system may not be possible. Parts warranty coverage that leaves only labor and refrigerant to pay. 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 $2,805, 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.
