"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."

"Repair man showed up a day early without advance notice and I was unable to give them access at the time. They were then unable to come at the original time (the next morning), but did manage to come that afternoon. The job was completed professionally and quickly aside from the scheduling changes. They were able to replace the failed capacitor and get the unit back online."

Energy Efficiency Auditing questions, answered by experts

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.

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.

Provide utility bills and clear access to all areas of the home, including the attic and basement.

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.

Fireplaces can theoretically help you save on heating bills if you lower the temperature throughout the rest of your home and heat only a single room that you occupy using the fireplace. However, in most cases, homeowners won’t save any money on heating bills. Gas and electric fireplace inserts could actually lead to a spike in your respective energy bills if you use them frequently, and if you don’t keep up with chimney maintenance and repairs, your traditional masonry fireplace could actually be a source of heat loss in the winter.
