in the supply duct. This can reduce the cooling capacity of an air
conditioning system by as much as 30%.This means a loss of almost one ton of cooling capacity from a
three ton system.
The air distribution system has the greatest effect. On the quality of the installation and the owner satisfaction,
The correct air quantity is critical for correct air conditioning system. Proper operation, efficiency, compressor life
performance and customer's satisfaction and can cause premature component failure.
Duct design and construction should be done with care. System performance can be lowered
dramatically through bad planning or workmanship. In cooling, a hot attic can cause a temperature gain

indoor air flow reduces system dehumidification capacity, and can leave the space humid and uncomfoltable.
