Home energy professionals determine how much air is entering or escaping from your home.

Professional energy assessors use tests to help determine a home’s airtightness. These are some reasons for establishing the proper building tightness:

• Reducing energy consumption from excess air leakage
• Avoiding moisture condensation problems
• Avoiding uncomfortable drafts caused by cold or warm air leaking in from outside
• Controlling outdoor contaminants, pests, and odors from entering your home.
• Determining proper sizing and airflow requirements of heating and cooling equipment.
• Determining whether mechanical ventilation is needed to provide acceptable fresh air and maintain indoor air quality in your home.
