"Glen and his team were prompt and professional during both installation and annual maintenance. We lost power during the last hurricane and the generator worked perfectly. Pricing was very good and Glen was even able to get me an extended warranty (promo from Generac). I would recommend Green Sun."

"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."

Generator Install questions, answered by experts

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

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. 

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

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.
