"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."

"I got multi quotes before I decided on a Solar company I was really worried about putting it on my roof And wanted to make sure I wouldn’t have one of those large bills at the end of the year. I’ve heard the horror stories! Tyler and Mr.Sunshine Soler answered all my questions. And always made themselves available. I would definitely recommend working with them. Their customer service is top notch and they stay apprised emerging solar technology. Their bid was considerably lower than the others and they were able to give me 100% coverage."

"My pump was leaking and getting worse. I had used Matt before and he did a good job. I gave him a call and he came over, checked out the pump and said I need a new one. When he told me the price, I decided to try to fix the pump myself. So after spending $375.00 on parts, the pump lasted a few more months before it seized. I called Matt and he came over on a Saturday to replace the pump. I should have listened to Matt in the first place. Now I have a super-quiet, energy efficient pool pump. They even cleaned the pool before they left. Just call Matt."
An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:
Blower door test: $350
Duct testing: $100
HERS test: $375
HERS certification: $200
Infrared imaging: $200
The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency.
A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.
Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.
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.
To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.
