"We have been quite pleased with GreenSavers's service and 'product' from beginning to end. We found them through their Chinook Book coupon for a home energy audit. Two nice people came out, poked, prodded, crawled and noted their way around the house. They were pleasant to talk with, and patient with my general energy-saving questions. A week later, one of them returned to present a proposal for a variety of projects. We didn't feel pressured to choose any one project. In fact, we told them that we'd need to pause the process. After a few month's diligent, professional follow-up, they checked in at the right time and with the right news: we might be a contender for the Zonolite Attic Trust (ZAT)'s 50% rebate on removing the vermiculite from our attic, air sealing the space, and then re-insulating. Who would say 'no' to them coming by to pick up a sample of our insulation? For better or worse, the result came back positive; we had vermiculite in our attic. With our permission, GreenSavers confirmed with the ZAT that we were candidates for the rebate. Woohoo! But wait, we were having some remodeling done in the kitchen. Could we please have the vermiculite remediated immediately, but wait on air sealing and re-insulating until that larger project was done? Sure, we were told. No problem. Finally, when GreenSavers came back to do the work, they did so quickly and expertly. As far as I can tell, they sealed the heck out of our two knee wall spaces, and -according to our wishes- preserved some usable storage space by using a different type of insulation. If you're still reading, you get the gist: this is a company you can trust. When my friends ask for referrals on this type of work, I won't hesitate to recommend GreenSavers. For what it's worth, Jennifer was our primary contact. She was very personable, professional and easy to work with."

"Mr. Gorman was professional and thorough. He did a blower door test on my house and identified several air leakage points that lowered my energy efficiency. He pointed out where I could mitigate leakage, ranging from the most easily done to the more challenging. After I sealed several of the easier-to-get-to points, he did another test and showed me a fifteen percent improvement. Mr. Gormanâ s tests and detailed evaluations are sure to lead to even more improvements to my energy profile and future money savings."

Energy Efficiency Auditing FAQs, answered by experts

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.

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.

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

Provide utility bills and clear access to all areas of the home, including the attic and basement.
