Customers say: Quick response

"Quality, affordability and professionalism at it's finest. I needed a panel upgrade for my generator, and an outlet installed outside near my basement door. A true professional, John arrived early, finished quickly and cleaned up after the job so well I couldn't tell any one have had been at my house. Clear and concise explanation of the job, the best price by far, and a friendly attitude. I give John my highest recommendation."

"EXCELLENT Wilson Bros. recently installed a second zone A/C unit in our house. In a nutshell, from initial call and sales/estimator Paul coming out to final clean up I've never been more pleased with a contractor and work accomplished. Everyone showed up on time as scheduled, Al & Cliff were outstanding at their installation work, and keeping me updated and involved on schedule and various options and layout necessities. I'm very particular, need to know what and why things are happening, and everyone was great to work with. Can't recommend them highly enough."
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.

Generator Install FAQs, answered by experts

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.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

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.

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.
