"We needed to replace our old HVAC system, and the entire process was smooth and stress-free. The crew was knowledgeable and gave us several options that fit our budget. The installation was clean, quick, and professionally done. Our home feels more comfortable than ever, and our energy bill is already lower. Five stars!"

"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."

"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."

"The man arrived on time.  Mild argument about parking permit (we live in permit pkg neighborhood).  Although I didn't specifically request it, he didn't inform me about how much repairs would cost.  He expertly fixed our furnace and relit pilot light.  He explained about the machinery.  
I had bought an online coupon through AL, and provider office knew that.   Unfortunately, he didn't know about it, but he graciously applied it.  Had I forgotten about it, I would have been charged more.

Energy Efficiency Auditing questions, answered by experts

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

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.

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.

You can increase your home’s load factor by replacing fuse boxes with a circuit breaker, hiring a licensed electrician to upgrade your electrical panel, upgrading wiring, or installing subpanels. An electrical inspection by an expert can help determine the state of your current electrical systems and how they can be improved.
