"Thorough audit. However, their focus is to sell a $50,000 home sealing project. That?s crawl space to attic. Payback on energy savings? A zillion years."

"Ben did an energy analysis of my home looking for places where energy might be leaking out He did a thorough investigation of the house including a blower door test and found several places where drafts were allowing heating and cooling to escape and raise my energy bills. I was surprised by the places where air was leaking out. I wouldn't have thought of those places. One was into the crawl space under the house, another was under two French doors. Who knew a relatively well-built house would have that many leaks. No wonder my electricity and gas bills were higher than I'd like."

Energy Efficiency Auditing FAQs, answered by experts

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.

Heat pumps transfer existing heat instead of generating it, using less energy. Compared to baseboard heaters, they can reduce heating costs by up to 50% and provide efficient cooling, lowering electricity bills and carbon footprint.

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours.
