"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."

Golden State Inspection Services, LLC is a service oriented, multi-inspector firm. We conduct buyer home inspections, seller home inspections and commercial property inspections, mold testing, infrared scanning and comprehensive energy audits. Golden State Inspection services conducts inspections throughout northern California.

"Summary: Zero communication after the inspection. I hate to leave a negative review but I believe this must be done given my experience. I had an inspector come by on 2/26 for pest control. He was considerate and thorough (the only reason I am giving two stars instead of just one), and he told me I would receive the complete quote on the following Monday. Well, that did not happen. After waiting on the quote for a whole week, I called the company on 3/5 and let them know that I didn't receive my quote. They said they would look into my case and call me back right away. Well, that did not happen either. So on 3/9, I called the company again to inquire on the status of my quote (I actually had to help them backtrack to find my record!). I was told that they would contact the inspector who came to my house and call me back ASAP. Well, today is 3/20 and I haven't heard back yet. I am giving up."

"Cody Brogdon, Austin and Jeremy were on time, efficient, put tarps down everywhere to protect our closet and floors. They put insulation material through a pipline from outside through the house and into the closet and into the roof over a time of 2 hours. The work could not have been better. The men were all very nice and cleaned up after the job was finished. Cody looked at our other energy appliances to evaluate them for being up-to-date. He informed us of what the company could do for us when we need such things, like AC /heater services. I would use them at the appropriate time, we are very impressed !"

Energy Efficiency Auditing questions, answered by experts

There are a couple of ways you can save on the cost of your home energy audit. First, find out if you qualify for programs like the Department of Energy’s Weatherization Assistance Program for low-income households. Next, check with your local utility company to find out if you qualify for any local rebate programs to offset the cost of this helpful service.

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.

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.

The best way to save money on home heating oil is to get large deliveries in the summer months when the prices are lowest. However, this method will only work if you have a separate storage tank or an unusually large primary tank. You can sometimes save money by opting into a delivery contract, as some companies offer set prices that they believe will sit at the average cost over the contract term. If the price of oil rises, you could enjoy some savings, but keep in mind that you might also pay a bit more if the price decreases.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.
