How HVAC Sizing Works
Proper HVAC sizing is crucial for comfort and efficiency. An undersized system won't cool or heat adequately, while an oversized one cycles on and off too frequently, wasting energy and wearing out faster.
Factors That Affect HVAC Size
- Square footage: The primary factor in sizing
- Climate zone: Hotter/colder areas need more capacity
- Insulation quality: Poor insulation requires larger units
- Windows and sun exposure: Large windows add heat load
- Ceiling height: Higher ceilings mean more air to condition
