"My experience was literally a nightmare. We have been out of AC since 7/15 and just got it back on 8/18 no thanks to Jason. I had to hire someone else. When it first went out he came over and cleaned out the drains but then we still continued to have the same issue the next day. When I texted him there was no response or an eta when he could come two days went buy and nothing. Finally he sent his other worker to come but I had already called a different company. They diagnosed the issue and Jason ordered the part because it was still under warranty. Took the weekend for the part to come in. He sent Scott to put it in and it still didn’t solve the issue. Jason didn’t even look at it but based on what Scott told him he ordered a new circuit board. Told me he was out of town when I asked him about the part and said it was going to be back ordered two weeks. Waited two weeks reached out Jason and the part was delayed another three days. Then it took him an extra three days to actually come install it even though he kept promising me tomorrow. Tomorrow. Came finally installed the part then said it was the thermostat so I bought a new thermostat. That didn’t work so he said he had to call tech support the next day. Said that tech support said it was my nest and he would come by the next day to install my old thermostat. He didn’t show up for three more days and his response was. “I’ve been in an attic all day. “ or he simply wouldn’t respond. Sent Scott over to install thermostat and it still didn’t work so they took apart and left my machine we wires everywhere and said it needed another part and would be back in the morning. We told him don’t bother coming back. I hired someone else who stayed all day until the job was done. Turns out it was a sensor and had he actually not done a half a**job he would have been able to diagnosis it. The new guy said they messes up things so bad it took him twice the amount of time. I have used Jason for years and will never call him again."

In other words, regardless of where you are in California, we can help you make the switch to solar!

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.

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

The effect a gas fireplace has on your gas bill will depend on how often you use it, the size of the rooms you’re heating with it, and the BTUs of the fireplace itself, but generally speaking, it should only cost a few cents an hour to run it when it’s on. It will consume minimal energy when it’s “off” if you have a pilot light running constantly, but some modern gas fireplaces don’t require a constant pilot light.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours. 

Gas fireplaces use either natural gas or propane—both of which will increase your energy expenses. On average, running a gas fireplace costs $400 to $640 per year; however, these costs can vary significantly depending on the fuel price in your area and the frequency of fireplace use. If you’re looking for a more energy-efficient option, consider switching to an electric fireplace.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.
