Energy Savings

Typical systems with unsealed or uninsulated sheet metal ducts that run through attics or crawl spaces can lose up to 40% of the heating or cooling energy that passes through them. The energy can be lost by simple conduction through inadequately insulated sheet metal ducts. It can also be lost through holes or leaks in seams that have not been properly sealed.

Properly designed and installed duct systems can have efficiencies of 80% or more for little or no additional cost, potentially saving a homeowner up to $200 or more per year in heating and cooling costs. Efficient duct system installations may also reduce equipment size, further saving money for new or replacement equipment.

You may be able to reduce your cooling cost by 10% or more simply by having your ducts sealed and insulated by a professional HVAC contractor. You should also consider increasing the insulation in other critical areas of your home using Johns Manville building insulation products.
