"Bill walked me through checking the outlet and circuits. We solved the problem with no service call needed. Harland has been my electrician since the early 2000's. They have completed many projects/repairs small and large (full panel replacement after water damage to installing a exterior spotlight). Staff answering calls is pleasant and professional, Bill gets back to customers usually the same day."

"Chris and Scott were very professional. They only needed two small holes to install the new wires and light. The cleanup in the kitchen was manageable. The price for the job was reasonable. They finished earlier than quoted. I recommended them to my coworker who needed to rewire her thermostat. She was satisfied with the work. I plan to use them again for other home projects."

"The furnaces were replaced in two different houses without any problems. The generator was placed in one of the houses with many delays. Waiting for parts we were told. When it was finally assembled it worked but daily test runs were happening. When we called to have our yearly check we were told it should only run once a week. A part needed to be replaced. Wilson Bros. shared that expense. It ran for about the next 5 years with constant maintenance but this year the mother board is gone. Wilson Bros have been wonderful but I question the quality of their equipment. One of the gas furnaces also requires costly maintenance. We never had this with our other gas furnaces. Love Wilson Bros. Don't like their replacement equipment. I just thought new things should last a little."
Three of the five heads are marked by the numbers in the blue circle. On the inside of the house is where you will find the mounted units. The slim ducts run alongside the white arrows and will eventually be covered to match the exterior of the house.
The slim ducts in the basement ceiling that connect from the branch box all the way to the 5 different heating and cooling units. These will be covered by the ceiling tiles once the job is finished.

"Michael replaced all the dimmers throughout my home and workspace… and he replaced a kitchen fan with lights for me… and fixed an antique lamp that had great sentimental value for me. He was on time and priced each job fairly. I am grateful for his work every time I dim a light and run the fan to cool my home during the warm er months of the year. I am planning on having Michael replace my outdoor walkway lights this spring."

"If you are looking for an honest, hard-working, and highly skilled electrician, look no further. I hired him to handle a massive job—taking my entire house off old knob-and-tube wiring and upgrading the main electrical panel.Rewiring a whole house is an enormous project, but he made the entire process seamless. He was incredibly neat, organized, and respectful of my home from start to finish. He kept me updated every step of the way, answered all my questions, and made sure every single detail was perfectly up to code. The new panel looks fantastic and is beautifully labeled.It is such a relief to have peace of mind knowing the job was done right by a true professional. His work ethic is outstanding, his pricing is fair, and I would recommend him to anyone in a heartbeat. Five stars!"

Generator Install questions, answered by experts

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.

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.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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.
