Proper Design and Installation

Why is proper design and installation so important?

Here are some FACTS about the importance of proper design installation of heating and air conditioning systems*:

Proper Equipment Sizing

• Oversized equipment increases energy use by 9%
• Oversized cooling equipment makes us feel cold and clammy
• Oversized equipment has more frequent maintenance problems and shorter equipment life

Proper Airflow

• Poor airflow produces a 10% increase in operating costs
• Poor airflow results in shorter equipment life
• Inadequate airflow results in poor comfort control
• Inadequate airflow results in lower indoor air quality

Air Conditioner Refrigerant Charge

• About 40% of all systems have an improper refrigerant charge, which can cause breakdowns and decrease the life of cooling equipment.

Tight Ductwork

• Leaks in the return ducts often bring in unfiltered and unconditioned air from attics, basements and crawl spaces
• Studies show that existing homes typically lose 35% of the system’s cooling capacity from duct leakage and thermal losses due to poorly insulated ducts
• Proper sealing and insulation will cut those losses in half

The combination of all of these facts would result in a system efficiency loss of approximately 40%
