Repair or ReplaceOpen worksheet

Homeowner decision guide

AC repair or replace: compare the repair with the installed system

A central-air quote can describe a component repair, a condenser swap, or an entire matched system. Those are different jobs. Record the repair total first; then enter each installed replacement proposal separately so rebates, warranties, and omitted work do not get mixed together.

What changes the answer?

  • Ask the contractor to identify the failed component and the measurements behind the diagnosis. A warm room may also reflect airflow or duct problems, not necessarily a failed outdoor unit.
  • For replacement, record the indoor and outdoor models and the sizing method. A lower equipment price cannot settle whether the system is properly matched and installed.
  • If a proposal states annual kWh savings, enter that figure as its own scenario. Without a documented figure, the worksheet does not invent one from an efficiency label.

Check the written proposal

Look for these items in each quote. If one is missing, ask whether it is excluded or will be priced later.

  • Indoor and outdoor equipment model numbers and capacity
  • Duct and electrical work, permit, removal, and disposal
  • Airflow, refrigerant charge, startup measurements, and labor warranty

Questions to take back to the contractor

  1. What test confirms this repair will restore cooling?
  2. Did the replacement estimate include the indoor coil and any required duct changes?
  3. What measurements will be documented at startup?

Compare your real numbers

Enter the repair quote now, even if you do not yet have a replacement price. Add up to three complete proposals later and keep their rebates and scope separate.

What this cannot determine

A repair may be sensible even for an older unit, and replacement may be necessary for reasons not captured by price alone. Have safety, technical feasibility, and local code requirements assessed by a qualified professional.
