Undetected air leaks and drafts, inadequate insulation, or worn out ductwork sealing can cause HVAC systems to use more energy without doing much to increase the comfort of your home. And, if your HVAC system is outdated (i.e., hasn’t been replaced or repaired within the last seven years or so), it may be producing warm or cool air inefficiently. Thus, by the time the air reaches the vents, it may be several degrees off from the starting temperature. By implementing weatherization techniques, your HVAC’s performance is improved.

When your home is properly weatherized, drafts are virtually eliminated. You will notice the temperature you set your thermostat to is maintained more easily. And, if you incorporate insulation along with air sealing, there will be a denser layer between you and the sounds outside. That may result in a quieter home.

Weatherization keeps the outside from coming in to your home. That includes pollen, dust and other allergens. It also reduces the chance for mold build up. The temperature around the inside perimeter fluctuates less in a weatherized home, resulting in less moisture build up during the summer and winter. The result? Cleaner, healthier air.

When your home’s energy performance is improved, the consumption of water, electricity, and fossil fuels (i.e., natural gas, coal, and oil) are reduced. Thus, greenhouse emissions – which contribute to climate change – decrease as well. By weatherizing your home, you are helping the environment.
