1. Which of the following is the most accurate tool for measuring
infiltration in a home?
A. Infrared camera
B. Smoke pencil
C. Blower door test
D. Thermometer
C. Blower door test
A blower door test pressurizes or depressurizes the home to measure
air leakage accurately, providing quantitative data on infiltration.
2. The primary purpose of a combustion safety test is to:
A. Measure home insulation levels
B. Ensure appliances are venting properly and safely
C. Determine HVAC efficiency
D. Check indoor humidity
B. Ensure appliances are venting properly and safely
Combustion safety tests verify that fuel-burning appliances are
venting properly to prevent carbon monoxide hazards.
, 3. What is the recommended first step before performing a blower
door test?
A. Turn off all appliances
B. Seal all leaks
C. Close all exterior doors and windows
D. Set thermostat to maximum
C. Close all exterior doors and windows
Closing all exterior openings ensures the blower door measures only
unintentional air leakage and not open doors or windows.
4. Which of the following materials has the highest R-value per inch?
A. Fiberglass batt
B. Extruded polystyrene (XPS) foam
C. Cellulose
D. Mineral wool
B. Extruded polystyrene (XPS) foam
XPS foam has a higher R-value per inch compared to most other
common insulation materials.
5. A duct system with visible holes and disconnected joints is likely
to:
A. Reduce energy efficiency and comfort
B. Increase heating and cooling efficiency
C. Improve indoor air quality
D. Have no significant impact
A. Reduce energy efficiency and comfort
Leaks in ducts cause conditioned air to escape, lowering efficiency and
reducing comfort in the home.
6. What does an infrared camera detect?
A. Airflow
, B. Temperature differences
C. Moisture content
D. Carbon monoxide
B. Temperature differences
Infrared cameras detect temperature variations, which can indicate
insulation gaps, air leaks, or moisture intrusion.
7. Which of the following is the primary source of heat loss in a
typical home?
A. Windows
B. Walls
C. Air infiltration
D. Roof
C. Air infiltration
Air infiltration often accounts for the largest portion of heat loss,
especially in older or poorly sealed homes.
8. What is the purpose of a manometer in combustion testing?
A. Measure CO levels
B. Measure gas pressure
C. Detect air leaks
D. Measure humidity
B. Measure gas pressure
A manometer measures gas pressure and draft, helping ensure
appliances operate safely and efficiently.
9. Which of the following is a sign of backdrafting?
A. Warm air from a vent
B. Smoke being drawn back into the home
C. High indoor humidity
D. Cold drafts near windows
, B. Smoke being drawn back into the home
Backdrafting occurs when combustion gases flow back into the living
space instead of venting outside.
10. When performing a home energy audit, which tool is best
for identifying missing insulation in walls?
A. Blower door
B. Infrared camera
C. Thermometer
D. Smoke pencil
B. Infrared camera
Infrared cameras can detect temperature differences across walls,
revealing areas with missing or insufficient insulation.
11. What is the standard unit for measuring air leakage in a
blower door test?
A. CFM50
B. R-value
C. BTU/hr
D. Pascals
A. CFM50
CFM50 stands for cubic feet per minute at 50 pascals, the standard
measurement for blower door air leakage tests.
12. A high-efficiency furnace is defined by its:
A. Size
B. AFUE rating
C. Fuel type
D. Duct length
