Additional Factors That Affect Sizing

Location & Climate:

  • Cold climates: 40–60 BTUs per sq ft.
  • Mild climates: 20–30 BTUs per sq ft.

Insulation & Windows:

  • Well-insulated homes can reduce BTU needs by 10–15%.
  • Poor insulation may require up to 20% more BTUs.

Ceiling Height:

  • Table assumes 8-foot ceilings.
  • Add 10–12% BTUs per additional foot of ceiling height.

Room Type Adjustments:

  • Kitchens: Add 4,000–5,000 BTUs for appliance-generated heat.
  • High-occupancy rooms: Add 400–600 BTUs per extra person beyond two.
  • Sunrooms: Add 10–20% depending on glass exposure.

Usage:

  • In cold climates, size primarily for heating.
  • In warm climates, size primarily for cooling.

System Choice:

  • Under 1,200 sq ft: Single-zone unit may be enough.
  • Over 1,200 sq ft: Consider multi-zone or multiple systems.

Professional Sizing:

  • For best results, request a Manual J Load Calculation from a licensed HVAC contractor.
