Notes & Disclaimers

This tool provides planning-stage estimates to help scope a multi-zone configuration. Final system design and selection must be confirmed by a licensed HVAC professional before purchase or installation.

  • BTU sizing is an estimate. Calculations use a 25 BTU/sq ft baseline adjusted for room type. Actual heating & cooling loads vary with insulation, glazing, sun exposure, ceiling height, occupancy, and air infiltration.
  • Manual J recommended. Final sizing should be verified through a Manual J load calculation performed by a qualified HVAC contractor per ACCA standards.
  • Specifications may change. Performance ratings, certifications, model availability, and lead-times are subject to change without notice. Confirm current details with Ascend Group prior to ordering.
  • Installation considerations. Refrigerant line lengths, electrical service, condensate handling, mounting clearances, and outdoor unit placement must comply with the manufacturer’s installation manual and applicable provincial codes.
  • Not a quotation. This output is a reference document only. It does not constitute a quote, contract, warranty, or commitment of pricing, availability, or lead-time.
