"An inexperienced/inept contractor had installed a generator for us and we parted ways with him when we discovered he neglected to pull permits for the work. We called Kope in for a consultation and they verified that not only was the generator not big enough to power our whole home (as was our intention) but it was installed illegally. We  hired them to guide us through the permit process, and bring the generator up to code which included piping a gas line through the garage, installing the correct sized pipes and fixing several mistakes with the electric. They were prompt, professional and knowledgable and coordinated seamlessly with the plumber they recommended to complete that part of the generator installation.  We now have have a safe, operating, legal generator. I would recommend Kope without hesitation and will use them for my future electrical needs.

"Roy is really a prof. He installed two overhead fans and a hanging lamp. The fans had a complicated control system but he was able to get them to work flawlessly. Bonus: he is really a nice person and he cleaned up too! I would recommend his work to anyone."

"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."

"I have used Pipe Works on numerous occasions as of this date and find them to provide excellent service at competitive prices. Their associates are great to work with and their prices are competitive. The work is always completed on time, as promised and the work area is left clean. I appreciate that they point out things that need repair in the not so distant future. It was great to wake up the other day with power coming from my new Kohler Generator"

"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

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

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.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.
