Every climate is different, and HVAC systems must be sized correctly to handle the local weather conditions.
Homes in California experience unique heating and cooling demands due to factors such as:
Outdoor design temperatures
Solar heat gain
Insulation levels
Window performance
Air infiltration
Humidity loads
A proper Manual J load calculation analyzes all of these factors to determine the exact heating and cooling capacity your home requires.
Oversized systems can lead to:
Poor humidity control
Short cycling
Higher energy bills
