"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"Attic masters did a good job at my house by cleaning the ducts. I spoke to them prior and they were nice to me. they gave me several options and explain to me the difference between each one and they recommended me which one to choose. The work that they did was good and the people that did the actual work were very nice. I will hire them again.

"The entire process went smoothly. Begin with a system quote from Paul Sherer with a design layout, followed by a feasibility study of the roof and where the panels are to be installed. I have a metal tile roof and the previous solar vendor actually rejected the project. Slingshot first installed the 240v outlet and that took 2 people a whole day to complete, as my electric panel is at the other side of the house from the garage. The panel installation took another 2 days that included the interconnect, upgrading the breakers on the panel. The staff was professional, courteous and focus on doing the job right. Then the city inspection and followed by submitting the application to PG&E. The approval took only 3 days which was a pleasant surprise. Slingshot came out to install a CDD so I can monitor the performance and output of all 13 panels. Not only the project completely very smoothly and on time, the final price I paid is exactly what was quoted from day 1. Now that my electric car is here, I think I can recover the cost within 2 years."

Energy Efficiency Auditing FAQs, answered by experts

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.

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.

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.

While some aspects of an appraisal, such as comparable properties nearby, are out of your control, there are several steps you can take to potentially increase your home's value. Make any necessary repairs and upgrades before the appraiser's visit, as they can only value what is currently part of the home, not its potential. Examples include renovating older areas, updating landscaping to boost curb appeal, and staging your home. You can also provide the appraiser with the cost of recent upgrades, which may increase your home's value by about 50% or more of what you paid for those improvements.

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.
