high efficiency claims are simply unfullfilled promises without effective
air delivery
Heating and cooling equipment has made great strides in terms of energy efficiency
and reliability in recent years. Unfortunately most homes still suffer from poor air
distribution and maximum efficiency gains are not realized because of faulty air duct
systems. The ductwork is probably the most overlooked component of
the overall air
conditioning system. Displayed is an example of the air conditioning duct system.
Properly sized, designed,installed duct systems are the key to system performance,
efficiency, and comfort. Effective air delivery throughout your home or building will
give you even temperatures in every room and increase overall system performance.
The true efficiency of a new heating and cooling system can only be attained when the
system is matched with a properly designed duct system. Installing a 18 SEER air conditioning
system connected to a leaking, deteriorated, or inadequate duct system will result in a
system that performs only as well a properly installed 13 SEER system. If you are replacing
or upgrading your system modifications can be done to solve problems such as room temperature
imbalance, air noise, and air leakage. These areas are critical in attaining the performance
from new air conditioning equipment.
-
Duct Size - Duct should be sized to deliver right quantity or air to each room and
provide even air temperatures throughout the home.
-
Undersized Return Air Ducts and Filter Grilles - Should be sized to allow
maximum air volume and provide adequate filtering.
-
Deteriorated Insulation - Duct insulation provides for minimizing the heat
gain as the air passes thorough hot attic areas. It also prevents moisture or
sweating of ductwork that can cause growth of mold and bacteria.
-
Collapsed Duct - An adequate free flowing area is necessary for air distribution and
reliable system operation.
-
Duct Leakage - The duct system should be sealed with no air leakage as to minimize
power consumption and not allow unfiltered attic air to be drawn into the home.
