When it comes to HVAC most home owners think of “that noisy thing outside”, the thermostat on the wall or the filter they have to change “every so often”. The truth of the matter is that the air distribution system can make or break expensive HVAC equipment.
Independent third party research has proven the air flow energy efficiency of steel duct is far superior to polyester flex products. Pressure losses up to 10 times or greater then steel duct are common occurrences when flex is used. That simply translates to higher energy bills, shorter equipment life and can easily contribute to poorer indoor air quality.
Installing an efficient heating and air conditioning system with steel ductwork will maximize the efficiency of the system and help reduce costly equipment failure.
Steel Air Distribution Systems have been the preferred product for air distribution systems for decades. Steel duct is the standard by which all other duct products are measured.
Products used today in place of steel duct afford home builders a cheaper initial installed cost. Unfortunately home owners suffer from a less efficient air distribution system for life of ownership. For better IAQ and lower energy bills, insist on Steel Air Distribution Systems.
Polyester flex interior has higher resistance to air flow than steel duct.
The use of polyester flex, while easy to install, permits poor installation practices.
If improperly supported, polyester flex will sag, further reducing air flow and increasing pressure loss.
Polyester flex bent too severely, crushed or compressed also reduces air flow.
Fiberglass duct board has higher resistance to air flow than steel duct.
When installing duct board, fiberglass particles can be dislodged into the air stream.
Cleaning duct board can cause damage to the fiberglass interior surface.
The porous surface of duct board can trap dust and dirt which help spawn mold growth.
