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
Rules vary by city. Ask the contractor whether a permit applies.
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.
