Before you sign

Six things to check before you sign

  • Ask for the diagnosis in writing

    Which part failed and why. A written diagnosis stops a small repair from growing on the day.

  • Repair or replace

    On systems over 12–15 years old, compare the repair against a replacement before you pay for a major part.

  • Permit

    A permit is required here. Make sure it is on the quote.

  • Check the license

    Look the contractor up in the state registry before you sign. Our quote check does it for supported states.

  • Rebates

    The federal 25C tax credit ended for systems installed after 2025. Utility and state programs may still apply.

  • Timing

    Replacements are cheapest to book in spring and fall, before the first heat wave or cold snap.
