Insulation and Ventilation

Maintaining proper attic insulation levels, as well as adequate attic ventilation, is extremely important to reduce energy costs as well as to maintain or improve roofing life expectancies. Insulation levels of R-19 or more are considered acceptable by today's standards. The insulation should not block the soffit or eave vents, and the roofing vents should be kept open to the outside for proper air circulation.

Ducting

Ducting for central heat and air systems can collect dust or other contaminated, and it is advisable to have all ducting cleaned at least every ten years or so. Seams and joints of the ducting can sometimes dry out or break which will allow air loss; all ducting should be periodically checked and sealed if needed. The insulation wrap on all ducting should be properly maintained to prevent heat loss or transfer.
