For an Ontario business replacing a rooftop HVAC unit, the equipment price is the starting point, not the complete project budget. Ask Infinite Home Services to define the work for your building before you compare financing payments.

Start with a site-specific scope

Identify the unit being replaced, the areas it serves and the issues you want addressed. Ask the contractor to explain the proposed equipment selection and any changes to controls, ventilation or existing connections. Do not choose capacity from a generic online example.

Ask which installation costs apply

  • Equipment supply and delivery.
  • Roof access, lifting arrangements and placement.
  • Connections, controls and any identified alterations.
  • Removal and disposal of the old equipment.
  • Commissioning, documentation and staff handover.

These are questions for the contractor, not a list of work every building needs. Mark exclusions clearly and ask who is responsible for coordinating each part.

Plan for business disruption

Confirm when heating or cooling will be unavailable. Discuss the installation window with tenants or staff and include any agreed temporary measures in the budget. Record who approves additional work if conditions differ from the initial site assessment.

Check incentives separately

Ontario's Save on Energy Retrofit Program covers qualifying efficiency projects. Check current measures, eligibility and application timing directly with the program before placing an order. Do not deduct an assumed incentive from your cash requirement before it is confirmed.

Review payment options using the complete quote

Send the itemized project quote to Mehmi Financial Group and identify the costs you want considered. Ask which costs are eligible and which remain payable separately. Compare any offered payment schedule with your business budget.
