A professional energy assessment (audit) provides an analysis of the safety and efficiency of your home’s airflow and heating/cooling systems. Undiagnosed air leaks, inadequate insulation, improper ventilation, faulty combustion appliances and leaky gas pipes not only waste energy and money, but can also cause health and safety problems. Therefore, a professional energy assessment should be part of every homeowner’s building maintenance and should be repeated whenever major improvements are made (such as room additions, attic/basement remodeling, multiple new windows) to ensure the house maintains proper ventilation and air sealing.
