"They replaced our old furnace with a modern, energy-efficient model. The installation was clean and hassle-free. Highly satisfied with the improved performance. The new system has already lowered our energy bills."

"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."

"Raymond was very professional and knowledgeable, and reflects his Master Electrician license .  His price was the best of 3 quotes I got.   His work was excellent, with great rapid communication,. He was on time and got the work done quickly.  He was able to set up the 240V line and outlet to charge my current ford fusion energi car, and be ready to charge the Tesla car if I decide to buy one in the future.  Reassuring that he has adequate insurance coverage for any work he does.  I will hire him again for any  future electric work I need done. I am glad to have found a professional, reliable electrician for my current and future needs.

"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."

"The reviews below me said it best: Ezra was fantastic! He was prompt, professional, and very informative. He explained to me each of the things he was doing, what he looked for in an audit, and what to expect. He also answered all of my questions about the kind of improvements that were worth it and those that were a waste of money. We were required to have an Energy Audit to sell our home and our realtor recommended Ezra from Landmark construction & energy crew. Lucky for us, Ezra found no recommendations and gave us a good "bill of health." What I like more is that if he does have recommendations, he doesn't perform any work himself, providing a truly unbiased opinion.  I fully plan on having Ezra perform an audit of our next home, whether it is required or not."

Energy Efficiency Auditing questions, answered by experts

A blower door test shouldn’t take more than an hour, and most can be completed in less than 30 minutes. Expect the test to take longer once you start searching for leaks with thermal imaging or want to include sealing such leaks in the time estimate. The test doesn’t take much time and can’t be rushed, but it will take longer in large homes or those with many air leaks.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Services by electricians can quickly get expensive, but there are a few ways you can save money in the process:

  • Bundle multiple jobs done at the same time to save on trip fees or flat fees for individual projects.

  • Get at least three quotes for service to find the best deal.

  • Buy fixtures, switches, outlets, and other materials beforehand to avoid product markup.

  • If you feel comfortable with it, have an apprentice or journeyman complete the work under the supervision of a master electrician. These electricians in training tend to charge less per project.

A good SEER rating for an HVAC system is typically between 15 and 20. However, minimum requirements vary by location; HVAC systems in northern states must have at least a 14 SEER rating, while those in southern states need a minimum of 15. For the highest possible efficiency, look for units with a SEER rating of 21 or higher. It's important to remember that a SEER rating represents the maximum efficiency a unit can achieve, not the level at which it will operate at all times.

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.
