One home brief
Give every bidder the same home facts, comfort problems, existing equipment and requested decision questions.
Two contractors can quote different equipment, duct work, electrical responsibility, commissioning and payment structures. A lower total is not automatically a better value when the scope is incomplete.
These checks measure written proposal completeness. They do not rate contractor honesty, workmanship, licensing or project suitability.
Give every bidder the same home facts, comfort problems, existing equipment and requested decision questions.
Normalize exact models, scope, permits, warranties, timing, exclusions and payment basis line by line.
Do not treat an omitted field as included. Mark it unclear until the contractor answers in writing.
Scope completeness is not a workmanship, honesty, licensing or suitability score; verify credentials and references independently.
| Field | Unclear proposal | Comparable basis |
|---|---|---|
| System | Different capacity or tier | Same load assumptions and published performance basis |
| Scope | Bundled description | Included/excluded/not applicable by field |
| Warranty | Parts warranty only | Parts, labor, registration and exclusions separated |
| Payment | Lowest monthly payment | Cash total, financed total and timing compared |
Compare capacity assumptions, comfort goals, efficiency evidence and supporting work—not brand names alone.
Exact models, permits, electrical, ducts, drainage, commissioning, labor warranty, exclusions and finance total should not stay unclear.
Two or three documented proposals normally reveal scope differences better than collecting many incomparable totals.
