Scope to include in your bid request

  • Identify the current system type, approximate age, service issues and rooms with comfort problems.
  • Ask for an appropriately justified heating/cooling load calculation, not simply a same-size replacement.
  • Define equipment efficiency, model numbers, thermostat, filtration, condensate disposal and ductwork inclusions.
  • Clarify permits, startup testing, balancing, line-set reuse and disposal of old equipment.

Photos, documents & drawings

Provide basic floor area, home layout, photos of existing equipment and access paths; installers should verify suitability during a site visit.
