"The actual install of the interlock switch was done well and was fair for the price. The electricians were quick and courteous. The pricing on the portable generator was less than generous (I found out after the fact that I could have gotten a nearly identical version at Menards for 30% less). I also asked for a final itemized invoice and receipt after my payment, but it was never received."

"We have a smoke alarm that is located 20 feet u from the floor. Several people declined to come out, including one that wanted $89 just to come and give us an estimate. The $89 did not apply toward the estimate if we accepted. Richard Riley, from Electrical Edge, had us text a picture and said he would be happy to do the job. He showed up on time and was very professional. We plan to use him on some other projects as well. Chris and Chuck Gibson Scotts, MI"

"Keith and Mike were wonderful. Great service and knowledgeable in their craft. The weather was terrible when they came to install my decorative outside shutters and they still got the job done in a timely manner. I will use them again and listen to their suggestions!"

Generator Install FAQs, answered by experts

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.

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.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

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.

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.
