A clearer replacement estimate

Equipment, labor, electrical work and warranty as separate lines in the scope.

A proposal from Comfort is written to be compared: scope, allowances and schedule, each on its own line.

How a proposal is built.

We separate the scope from the allowances and the schedule, so you can see what a figure buys and what would move it. Permits, engineering and inspections are listed where they apply, never folded into a number you cannot check.

A HVAC REPLACEMENT PLANNING CHECKLIST
  1. Which items are allowances, and what happens when a selection exceeds one?
  2. How are permits, engineering and inspections shown in the proposal?
  3. What would change the price after the contract is signed?

Put this perspective into practice.
