Air Duct System Replacement
Your unit is attached to a delivery system called a duct system or duct work. It is designed to deliver the air to every room in your home. All of the air is moved through your duct work 3-5 times per hour.
If the duct work is too little it adds resistance to the blower motor which makes it difficult to deliver air.
This creates an increase of energy usage, cold and hot spots, and frequent system failure. If the duct work is too large it takes longer to deliver the air. This creates weak air flow and an increased utility bill.
