Frequently asked

Is $7,200 a fair price for full central AC system replacement (~3 tons) in Massachusetts?

Yes. $7,200 is right around what most homeowners in Massachusetts pay. Anything from $2,550 to $14,190 is inside the normal range for an HVAC company; above $14,190 it is worth getting a second quote.

Why do quotes for the same job vary so much?

Tonnage and SEER2 rating; a 16+ SEER2 system costs thousands more than a minimum-efficiency one. Ductwork repairs or modifications found during the job. 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 $14,190, 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.
