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.
14.3 SEER2 is the floor here
New systems must meet the regional minimum. Higher ratings cost more up front and save on power every summer.
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.
