"This afternoon Trevor came to my house to repair an outlet. He was knowledgeable, and explained how he would proceed with the repair. He worked quickly and efficiently, and it should be noted he cleaned up upon completion. I would highly recommend Princeton Electrical in the future. Trevor was excellent."

"We called PipeWorks for an emergency hot water heater replacement on a weekend. In approximately one hour, they had a technician, Pablo, at our house to assess the issue. Pablo was extremely professional and made safety during the COVID pandemic a top priority as he did his work. He was able to get us a replacement water heater and install it the same day and completed the job within a few hours of when he first arrived. He answered all of our questions, did a terrific job, and even called us later that evening when we had reached out through the main number with a follow-up question. We were so grateful for Pablo's expertise and professionalism."

"Ken and his team from Transform Electric were terrific! Ken immediately contacted me and was able to come and give me an estimate right away. We started the project a few days later. I had four rooms that needed new recessed lighting installed. The team came on time and started working. They were very professional and reliable. They moved all my furniture and covered what was necessary. When it was all done, everything looked great and I was very pleased with the outcome. They also cleaned up after they completed the job. Overall they did a fantastic job and I would definitely recommend them to others!"

Generator Install FAQs, answered by experts

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

Costs range from $500 to $2,500, depending on generator type and installation complexity.
