"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’m very pleased with Excellence Electric. The owner, Raymond Lezama provided excellent customer service. He thoroughly inspected what needed to be done and gave me a couple of options. He explained the differences between the options and gave me his recommendation. The work was done quickly and thoroughly. And the price Raymond quoted was very reasonable! Great work Raymond. Thank you!"

"We purchased the home energy audit with the understanding that we would be receiving a more extensive analysis of our home energy usage along with possible solutions. Ultimately, the process was more about a presentation for solar panels that anything else, which was not what we were looking for when we purchased the offer. Richard was very professional and thorough in his presentation and presented options regarding areas to save in terms of energy usage but those areas were not as thoroughly explored as the solar discussion. Green Source Energy should be more direct about what the Home Energy Audit entails so buyers can make an informed decision."

"Acvolt Electrical INC. is very professional and efficient when they work. They were able to come in, diagnose the problem, and fix the problem by the next day (they had to order parts). They were highly knowledgeable and easy to talk to when explaining what was going on. I highly recommend them!"

Energy Efficiency Auditing FAQs, answered by experts

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.

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.

A home energy audit costs about $420 on average, with prices ranging from $100 to $2,250 or more. The final cost depends on factors like your home's size, location, the thoroughness of the audit, and the specific tests performed. A basic Level 1 walk-through inspection typically costs between $150 and $200, while a comprehensive Level 3 audit with detailed testing and a report costs around $900. Homeowners may be able to use the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit to cover up to $150 of the audit cost.

Costs for common individual tests include:

  • Blower door test: $350

  • Duct testing: $100

  • HERS test: $375

  • HERS certification: $200

  • Infrared imaging: $200

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.
