"Great job by the electricians. They arrived early, called the boss and asked questions when they were not sure. Offered suggestions on how to bring the property up to code, identified the problem and installed a smart thermostat. Job well done."

"I went on Home Advisor for help contacting an electrician. David from Bay Electric of Northern Michigan LLC contacted me about 2 hours later. David came to my house a couple days later, to go over what my needs were. My project was to upgrade my electric box from fuse panel to breaker box, upgrade electrical service from 60 amp to 100 amp, and install electrical service to a new pole barn. David gave me an estimate which I accepted. David did the whole job including permits, scheduling with Consumers Power, final inspection.etc. David also supplied wire, 2 breaker boxes, and everything needed. Very professional, friendly, and complete service. I highly recommend this company. The job was completed in 1 day. David is coming back in Feb. to connect my generator to whole house service for when power outages occur."

Generator Install questions, answered by experts

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

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. 

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

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.
