Weatherization installers and technicians make homes and buildings more energy efficient by installing or changing existing features of the structure.

Weatherization installers and technicians inspect homes or buildings. They check for drafts and leaks and check the attic and crawl space for insulation (and any damage to it). Special tools are needed to determine airflow and where hot or cold air might leak.

Once weatherization installers and technicians complete their inspections, they tell clients what should be replaced, installed, or changed. Technicians explain each option, from installing new water heaters to using lower watt light bulbs. They estimate the costs of these changes for homeowners.

Weatherization installers and technicians have to understand both electrical and heating systems. These workers must have good mechanical skills and be able to work with a variety of equipment. They use special tools for testing and installing or fixing new doors, windows, air ducts, and insulation. They also perform heating, ventilating, and air-conditioning (HVAC) work. They also work with:

• Wood
• Drywall
• Windows
• Caulk

They install insulation in attics and other hard to reach spaces. They place thermal blankets on water heaters and wrap pipes and ductwork to seal leaks and reduce energy costs.

Weatherization installers and technicians schedule appointments and maintain work and billing records. They also must clean and maintain their tools.
