Compare the job.
Then the price.

Make each quote cover the same job.

Ask each service to describe the diagnosed fault, proposed repair, equipment or model, included parts and labor, and exclusions. Compare a repair with a repair; keep a replacement offer separate unless every provider is quoting that same replacement.

Separate a visit charge from a repair price.

A free estimate can differ from paid diagnosis. Check whether the visit fee is included, added on top or credited only after approved work. This worksheet adds a fee only when you mark it as extra and enter its amount. If the fee or credit is unclear, it leaves that subtotal unconfirmed.

Ask what could change the invoice.

Confirm tax, parts availability, disposal, access work, permits where needed, and the conditions for approving additional work. Record the warranty for parts and labor separately from any manufacturer coverage. A missing term is a question to ask, not proof that a service does not offer it.

Use price as one part of the decision.

For home projects, the FTC recommends multiple written estimates and cautions against automatically choosing the lowest bidder. Ask the service to explain significant differences and confirm credentials, job scope and written terms.

Only details you enter are compared here. The worksheet does not verify an offer, diagnose a fault or predict a fair local price.
