"We hired Bob to install an electrical outlet on a separate line for our electric outdoor grill and a 100 cfm exhaust fan our bathroom. No moisture appears on our bathroom mirror and surrounding area. They kept all appointments on time and gave us exactly what we asked for. We would hire Bob again. His men were very courteous."

"Very accommodating and helpful with suggestions when it was noticed that the fan we purchased was defective..our installer came back in the afternoon to install the replacement fan. Check your purchases at Home Depot before you leave the store...our Hunter Fan was definitely returned by a previous customer and then put back on the shelf. The Company and installer handled the job very efficiently and professionally and we would highly recommend."

"I've used Jeff on 3 different occasions- a complete kitchen and bathroom gutting, electrical updates at a new house 2x. I'd recommend Jeff's work without hesitation. He makes good recommendations, does clean and quality work and charges a fair price."

"Aubrey is great. We set an appointment which he was prompt for. He estimated the time which he was also right on the money, and the work was done neat, clean, and everything tested perfectly. This is the second time I have had him do some work for me and will call him for anything else electrical that I have."

Generator Install questions, answered by experts

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. 

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.

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.

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.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.
