"Edge Energy did an energy audit for us, then sealed the house, installed a new roof with excellent insulation, and an ERV fan to ensure fresh air. They were a delight to work with throughout, very friendly and professional. We needed some follow up work due to quirks in the house, not bad work by Edge, and they did it promptly and without charge. I couldn't recommend them more highly."

"Brian was the one who installed my air conditioning unit. excellent work, not only on time, took several hours but he did an excellent job. after the installation, he cleaned my room where it was installed. He worked neat clean. costumer support conact was provided for future service. He was very efficient. Very fair pricing, they also provide a discount on service during the winter time. He was the repairman for my old air conditioning unit. I am very very pleased with the service, I would highly recommend them."

"We contacted Mr. DeWitt about fixing a second story sliding glass door that was leaking water into the level below. He responded quickly to my initial inquiry and scheduled an appointment within a few days. He showed up on time, examined the problem and proposed a solution which involved pulling up about a third of our decking to get to the flashing. He also looked at our front porch columns, which had shifted during this summer's earthquake and had become detached from the porch overhang. His pricing beat any other handyman we had contacted, so I inquired about a few more items from my "wish list". He priced these items very reasonably and proposed solutions which improved safety and saved us money.

Mr. DeWitt scheduled the date to begin the work, and he and his helper arrived at the time promised with the materials needed and ready to work. They worked quickly but neatly and dealt with further problems found on the front porch columns after the vinyl wrap was removed. He proposed budget-conscious solutions and reconstructed the column bases so that wood rot caused by water would not be a problem again. The work on the patio door was completed over several days; after it became apparent that over half the decking boards would need to be removed, he suggested that we just replace the whole floor, which was pretty worn, with new decking boards, and he gave me a break on the labor costs. The door has since withstood several very heavy rainfalls and has not leaked again.

His carpentry work on my kitchen cabinet over the microwave was outstanding. You would never be able to tell that the cabinet had been altered. He properly reinstalled my microwave at the proper height and I could not be more pleased. Through the entire process, he kept me informed about what was happening.  I would thoroughly recommend Mr. DeWitt and plan to call him again for further "wish list" items!"

Energy Efficiency Auditing FAQs, answered by experts

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.

Yes, Tesla Powerwalls are worth the upfront costs, as you can recoup your investment within six to eight years. Plus, they provide peace of mind that you'll have power during a power outage, and, depending on the system you install, you can become energy-independent. While they may be more expensive than other solar power systems, they offer higher battery capacity and lifespan.

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.

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.

  • 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.
