"Just an outstanding experience end-to-end with Matt. He responded to the outreach within minutes and was able to give me a quote a few hours later that was very fair. We installed an induction stovetop and needed a new 50amp circuit and line run in our old house, crawl space and all. He showed up right on time, and made quick work of it. Very professional and friendly. He even stayed a little longer after the job was complete to help me diagnose another problem. Couldn't recommend him more highly. Would hire him again in a minute."

"Jose was great to work with. He was quick to respond, came by on short notice to have a look and provide a quote for the work (Installation of one new smart thermostat and replace one old thermostat with new thermostat; requiring separation of baseboards due to wattage). Very competitive pricing, showed up on time at each appointment and got the work done quickly. He left the place cleaner than before, and walked me through everything after the installation. Can highly recommend Jose for any electrical work!"

"I had both electricians and plumbers who performed the work of the generator installation, transfer install as well as the plumbing to the propane tank-generator. Considering the time of year with hurricanes and inclement weather, the generators and transfer switches were backordered however, my job was completed within a 2 month period from the initial quote to finish- considering all of the obstacles that we faced, they did a fantastic job."

Generator Install questions, answered by experts

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

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.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.
