"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."

"From the office folks to the electrician who did the work -- friendly and professional. They quoted the lowest price of three estimates and did the work within a couple of weeks. I purchased my generator elsewhere online... and VMA walked me thru the process of hooking it up, running it, and shutting it down. Very helpful."

"Amaury was very professional and did a good job. We delayed the work until we could take delivery of our generator so that he could test everything together and go over the transition with my wife and I. He was neat, accommodating, patient and thorough in describing how things worked. I would recommend him."

"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

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

Costs range from $500 to $2,500, depending on generator type and installation complexity.

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

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.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.
