Get a written scope you can compare
Review system inventory, then connect the observation to its source, system location, and a written scope.
DIRECT ANSWER
Start with the condition, not the sales package
A useful estimate names the system, evidence, components, access method, cleaning method, protection, exclusions, products, price, and result check. A price without scope cannot be compared. EPA recommends talking with multiple providers and getting written estimates before deciding.
Do not use an advertised coupon as the working total. Count systems, returns, supplies, and unusual access only to understand the proposal, not to invent your own price. Require written approval before add-ons.

What deserves a closer look
Included components
The estimate should say whether registers, plenums, blower, coils, drain pan, air handler, and ducts are included, excluded, or referred to another trade.
Change control
Add-ons should include evidence, price, and your approval before work. A provider should not hold the system open while pressuring a decision.
