Holding a furnace replacement quote and wondering if it's fair? You can't tell from the number. You can tell from what's around it. New on the blog: the eight things a real estimate includes (a visit to the house, a load calculation instead of "same size as the old one," exact model numbers, a venting plan, an item-by-item list of what's included, the two warranties named separately, rebates that actually apply to your city, and one written total that doesn't expire when the salesperson leaves) plus the seven red flags. Number seven: a "cracked heat exchanger" diagnosis with no photo. Ask to see the crack. If any of the flags sound familiar, send us the quote. The second opinion is free and in writing. Link in bio.
