ISSUES: An oversized air conditioning unit can have many negative effects:
- Increased initial cost for installed heating and cooling equipment
- Improperly sized duct system, ducting accessories and over-sized indoor blower fan
- Noise issues from a larger than needed indoor blower fan
Detrimental to:
- Energy consumption
- Comfort (air-conditioning is less effective in the summertime, combined with relative humidity issues)
- Indoor air quality (poor room-to-room air mixing & nuisance drafts from high blower speeds)
- Varying air temperatures from room-to-room
- System durability and lifetime expectancy
BENEFITS: When your house has accurate Heating & Cooling Load Calculations, it has a direct impact on many things:
- Initial Capital Costs (Lower Installation Dollars- Saving you money)
- Energy efficiency for the life of the units (lower monthly utilities for correctly sized units- Saving you money)
- Occupant comfort: improved airflow throughout the house and minimizes relative humidity concerns
- Minimizes nuisance drafts and reduces system noise from the blower fan & air moving through supply ducts
- Indoor air quality (less mildew build up within walls during the summer season)
- Minimized temperature variations between rooms
- Longevity of equipment (prevents short-cycling of units, units will typically last longer- Saving you money)
