Conducting an effective DIY energy audit requires specific tools and systematic methodology. While professional auditors use expensive equipment like blower doors and thermal cameras, DIY auditors can achieve excellent results with readily available tools and careful observation.
Essential DIY Audit Tools ($50-150)
Infrared Thermometer ($30-80):
Non-contact temperature measurement identifies hot and cold spots indicating insulation problems, air leaks, and thermal bridges. Point the device at surfaces to measure temperature differences revealing hidden issues.
Smoke Pencils or Incense Sticks ($10-20):
These generate visible smoke for detecting air movement around potential leak points. Hold near suspected leaks on windy days to observe smoke movement indicating air infiltration.
Flashlight and Headlamp ($20-40):
Essential for examining dark areas like crawl spaces, attics, and behind appliances. LED models provide excellent illumination while remaining cool during extended use.
Digital Multimeter ($25-50):
Measures electrical consumption of individual appliances and identifies phantom loads from electronics in standby mode. Look for models with clamp-on current measurement capability.
Measuring Tape and Notebook ($15-25):
Document findings systematically with measurements and sketches. Digital voice recorders or smartphone apps can supplement written notes.
Safety Equipment ($20-30):
Include work gloves, dust masks, and safety glasses for attic and crawl space inspection. Non-slip shoes with good traction are essential for roof and ladder work.
Advanced DIY Tools ($100-300)
Thermal Leak Detector ($80-150):
Consumer-grade thermal detectors identify temperature differences indicating insulation problems and air leaks. While less precise than professional thermal cameras, they effectively locate major issues.
Digital Hygrometer ($25-40):
Measures humidity levels identifying moisture problems that affect comfort and energy efficiency. High humidity requires more cooling energy, while low humidity increases heating needs.
Combustible Gas Detector ($60-120):
Identifies gas leaks around appliances and supply lines. Essential safety tool when auditing homes with natural gas or propane systems.
Power Monitors ($50-200):
Plug-in devices measuring real-time electrical consumption of individual appliances. Some models provide cost calculations and identify energy-wasting devices.
