Put the proposals on the same scope.

Check the assessment and equipment details

Ask each business to identify the exact proposed equipment and explain the selection basis. Record whether the proposal includes only a replacement component or a coordinated heating and cooling system. Compare how each proposal addresses your stated comfort goals.

Ask for compatibility and distribution assumptions to be explained. A brochure rating does not establish the installed result or predict your utility bill.

Use a complete project checklist

• Assessment and design responsibilities.
• Equipment models and retained components.
• Distribution and control changes.
• Electrical, gas, drainage and other trade work.
• Permits and inspection coordination where applicable.
• Removal, disposal and protection of the property.
• Installation checks, documentation and user handover.
• Taxes, payment stages and change authorization.
• Written warranty terms and follow-up contact.

Ask who is responsible for each item and identify exclusions explicitly. Verify the actual business identity, relevant qualifications and insurance before agreeing to work.

Keep forecasts and incentives conditional

If a proposal includes estimated savings, request the assumptions and calculation basis. If it mentions an incentive, verify the current program rules, equipment and application timing with the program itself before relying on the amount.
