# HVAC Installation Closeout Record Checklist A heating and cooling replacement should end with more than a working thermostat. Homeowners need a compact closeout record that explains what was installed, what was changed, and what still requires attention. Keeping these details together makes future service calls faster and gives you a clear reference if a warranty question appears. Start with the final scope and price. Compare the signed proposal with the installed model numbers, efficiency ratings, accessories, electrical work, duct changes, permits, and disposal charges. If the final invoice differs from the proposal, ask for each change in writing. A practical [HVAC quote comparison tool](https://www.clearhvaccosts.com/hvac-quote-checker) can help organize line items before you accept a bid or approve a change order. Photograph the indoor unit, outdoor unit, data plates, disconnect, drain routing, filter location, thermostat wiring, and any repaired duct sections. Save commissioning results such as temperature split, static pressure, refrigerant charge method, airflow settings, and combustion readings when applicable. Record the permit number and inspection result as well. Collect the warranty certificate, equipment registration confirmation, labor warranty, maintenance requirements, manuals, and the installer's contact details. Ask whether filters, surge protection, condensate pumps, line-set covers, or code upgrades were included. The [HVAC hidden-cost checklist](https://www.clearhvaccosts.com/hvac-hidden-costs) is useful for spotting items that are easy to miss during closeout. Finally, note the date for the first maintenance visit and keep all documents in one folder.
