WRITTEN SCOPE

A useful HVAC quote defines the installed project—not only the equipment.

The total is not comparable until the proposal identifies exactly what will be installed, what supporting work is included, what is excluded and how completion will be verified.

Decision checkpoints

Make every important field explicit.

These checks measure written proposal completeness. They do not rate contractor honesty, workmanship, licensing or project suitability.

Exact system identity

Require outdoor and indoor model numbers, capacity, efficiency evidence and the proposed matched-system reference where applicable.

Installation scope

Identify removal, line set, electrical, ducts, drain/condensate, controls, permits and access work as included, excluded or not applicable.

Startup and closeout

State commissioning measurements, owner documents, registrations, warranties, final invoice and change-order approval process.

Payment basis

Separate cash price, financed price, APR, term, payment, total paid and any prepayment terms.

Side-by-side basis

Replace vague wording with comparable evidence.

Field	Unclear proposal	Comparable basis
Equipment	Brand or series only	Exact indoor/outdoor models and matching evidence
Supporting work	Included as needed	Electrical, ducts, line set, drainage and controls itemized
Completion	System installed	Permit closeout, commissioning and owner documents stated
Price	Monthly payment	Cash and financed totals with exclusions

Before signing

Questions that protect the decision.

What can create an extra charge?+

Require written exclusions and the process for pricing and approving a change order before work proceeds.

Who is responsible for the permit?+

The proposal should identify responsibility, inspection and closeout rather than assume permits are unnecessary.

What proves the installed result?+

Ask for relevant startup and commissioning records, exact model/serial documentation and final warranty terms.

Official references

Verify efficiency, installation and financing claims.
