Energy Efficiency Auditing questions, answered by experts

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

Common warning signs of an overloaded electrical panel or meter box include frequent circuit breaker tripping, flickering or dimming lights, scorch or burn marks, and a burning scent coming from the panel. A circuit breaker trips as a protective measure to prevent overheating and potential fires. If you observe any of these signs, turn off the affected circuit breaker and move some devices to a different circuit. If the problem persists after turning the breaker back on, you should contact a professional electrician to resolve the issue.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.
