Energy Efficiency Auditing questions, answered by experts

While installing your new furnace, you should consider hiring a pro to perform a home energy audit . This audit will give you a handy list of any projects you could undertake to improve your home's overall energy efficiency rating, including replacing or sealing windows and insulating the attic. These improvements can help save you money each month in utility costs.

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.

Costs depend on pipe length, accessibility, and whether additional services are required.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

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.
