Before you sign
Six things to check before you sign
Ask for model numbers
The outdoor and indoor model numbers let you check efficiency, warranty and compare quotes line for line.
Repair or replace
On systems over 12–15 years old, compare the repair against a replacement before you pay for a major part.
Permit
Most places require a mechanical permit for a replacement. Ask whether 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.
