Energy Efficiency Auditing questions, answered by experts

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.

Audits typically take 2-4 hours, depending on the property size and energy systems.

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.

A home energy audit costs about $420 on average, ranging from about $100 to $2,250 or more. Cost factors include the size of your home, the type of testing, and the thoroughness of the audit. A Level 1 walk-through inspection will cost between $150 and $200 for the auditor to point out inefficiencies in your home. On the other hand, a more thorough Level 3 audit with testing and a detailed report will cost about $900.
