We are independent energy consultants who reduced our own energy use and saved several hundreds of dollars monthly on our utility bill and made our homes more comfortable and now are helping others achieve similar results. We are not contractors. We do not get paid based on the recommendations we make or the recommendations you choose to do. We want to provide you with what you need to do, explain why you need to do it so that you have all the information you need to make an informed decision. Once you've made the decision on what you want to do, after having all the information necessary to make an informed decision, we will help you implement your decision. We have vetted many home performance contractors and we know they will do the quality work you want and deserve. There are PGE rebates available and financing available that we will show you how to leverage to your advantage. So give us a try. You'll be glad you did.

Superior Insulation installs all types of attic insulation. We offer well known brands like Owens Corning®, Knauf and Certainteed . Our crews install according to manufacturer's specifications. Our crews are insured, trained, drug tested and background checked.

"Our job was much more difficult then anticipated and they had many challenges. They worked relentlessly to get the job done, as promised. We really appreciate their effort, the way they prepped our home, cleaned up every day and worked as scheduled. It is hard to find people who perform the work as promised, show up on time and communicate everything to the homeowner. This outfit exceeded our expeditions. Highly recommend them!"

We are locally owned and operated, and love serving the Greater Bay Area, and Central San Joaquin Valley. Our focus is residential air conditioning, heating, full-service plumbing and energy upgrade services including home energy audits, air sealing, wall & attic insulation. We love residential. We love working with homeowners and helping to take care of their precious homes. We also keep busy doing light commercial service. Serving California since 1954, financing options available, home of the $89 Tune Up and Efficiency Boost.

"EXCELLENT! When our heater died, we found them on Angie's List. Jeff came out very soon to give us a quote. He was very informative and professional. We had read the reviews and decided to go with them without even getting other quotes. It wasn't the lowest price around I'm sure.....but it was about what we expected, other than a couple of newer additions which I'm sure we will be happy with. 5 young men (Joaquin/Ben/Dillon/Alvaro/Allen) started the next morning! This was quicker than it might have been because it's April & not high season for worrying about heat. These men were Friendly, Informative, Efficient, Capable. I can't say enough good about them. I have a home office and an income tax business, so I was here working and they were here for 3 full days. I was Completely comfortable with them around. It was an Exceptional job done and I'm kind of going to miss them! ;-) Great Job ABC!"

NRG Clean Power is California’s leading clean power provider. We leverage over 30 years of superior customer service installing solar from the south of San Diego to the northern border with Oregon. In other words, regardless of where you are in California, we can help you make the switch to solar! Not only do we offer top-tier solar services, we are also a total home performance company, devoted to sustainability and energy efficiency. We offer fully customized home and business solar installations with battery backup capabilities. We do not service solar systems that we did not install. We believe the future is clean, renewable energy and with your help we are committed to creating it together. Customer satisfaction is a crucial aspect and the cornerstone of our business. As a result, we have earned the prestigious Diamond Certification 4 years in a row, along with the 2019 Angie’s List Super Service Award. NRG Clean Power offers the finest solar products at the best rates with finance options for everyone. We will be with you every step of the way and for years to come. Check out our promos to take advantage of our best deals. And ask about our Referral Program that allows customers like you to earn cash bonuses for referring friends and family!

"No doubt they hire great installation people, but their communication and honoring their quotes has little to be desired. I will elaborate. I was given a quote, left on my voicemail. I responded the next day letting NRG know I accepted their quote. 1 week later I received a phone call telling me they wouldn't honor the quote give, and they cited the reasons as Tarif's. This was back in April 2025. I still went with NRG, albeit at a$1000.00 increase. The second reason I wouldn't recommend this company, and this for me is the final straw, after installing my solar NRG didn't let me know I needed to have an ESR release, in layman's terms this is necessary for your power company to accept your new solar system. I found out this information when they contacted me in August 2025. NEG blamed the company who upgraded my Electrical Panel. NRG INSTALLED MY SOLAR AFTER THE PANEL WAS UPGRADED. Since this company doesn't communicate with its clients I would say go with another company."

Energy Efficiency Auditing questions, answered by experts

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

A couple of the best ways to find a reputable energy auditor is by determining whether they are HEP-certified by the Building Performance Institute (BPI). This certification will help you narrow down your list of professionals to the most qualified pros with the most relevant experience. 

You can also choose from the Department of Energy’s certified list of energy auditors or Angi’s contractor licensing tool to find pros in your area.

Audits typically take 2-4 hours, depending on the property size and energy systems.

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.
