How HVAC System Sizing Works
An HVAC system that is the wrong size causes comfort and efficiency problems. Proper sizing is one of the most important parts of a replacement.
Why Size Matters
- An oversized system short cycles and does not dehumidify.
- An undersized system runs constantly and never cools enough.
- A properly sized system runs in steady cycles and controls humidity.
How It Is Determined
Sizing is based on a load calculation that considers the home's square footage, insulation, windows, climate, and layout. A service estimate can determine the right size. See AC replacement and HVAC installation.
