Problem:
Inadequate Insulation Levels
Effects:
• Warm & cool air escapes, causing heating and cooling equipment
to work harder than necessary.
• Ice damming may occur, leading to roof and ceiling leaks.
• Freezing Pipes
Problem:
Duct Leakage
Effects:
• Uneven
distribution of warm or cool air
• Uncomfortable room temperatures
• Poor heating and cooling equipment performance
Problem:
Air Leakage
Effects:
• Drafts & cold spots
• Overworking of heating & cooling equipment
• Moisture problems leading to peeling paint, mold, mildew or structural
damage in walls and attic
• Inadequate air exchange causing unhealthy air quality, high humidity or
dryness
Problem: Improperly
Vented Appliances
Effects:
• Dangerous carbon monoxide fumes can enter the living space when gas or
oil-fired appliances are not vented properly. This is
known as backdrafting and often occurs with poorly vented
heating systems, stoves, water heaters, and clothes dryers.
