"I had Harland Electric come out and check out my electrical panel due to an issue where the electric dryer kept tripping the circuit breaker. (There was water near the breaker that I observed when it did this.) I had a few other minor things I wanted to have them check at the same time. The guys (Kevin and Derek) were great and knowledgeable and recommended I replace the panel due to the corrosion. I got an e-mail from Bill Harland who gave me information on what my options were and some estimates. I asked a bunch of questions and Bill was a great help in making a final decision. I felt he was honest about his recommendation as I debated doing a more expensive upgrade and Bill felt for my situation it would be overkill. I opted for a full replacement 100amp with the feed from the outside. (My house is very small and 100 amps has always been more than sufficient) Kevin and Mike showed up on time for the appointment and did an awesome job on the replacement. The work was high quality, neat and professional. The guys were also great around the young children (2 and 5), they very friendly and even my wife was comfortable (and that's impressive). They cleaned up completely and even took care of a couple of additional things that I had hoped (but didn't expect) they'd be able to get to. There were no surprises with the bill and within the estimate (even with the extra stuff). Judy in the office was also very nice and great with setting up schedules and dealing with the deposit. I will definitely use Harland again if I need electrical work done."

"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."

"The two young men who performed the installation were informative, professional, cordial, and they left the scene spotless. There was a technical problem with the engine on the generator itself, which they weren't able to help with, because they weren't licensed to work on the specific brand of generator. That might be something to check on before hiring for this type of job."

"Our project was a panel upgrade and generator install. From the first point of contact through point of completion Kevin's level of professionalism, customer service and follow through were beyond exceptional. He is very skilled and knowledgeable in the electrical field. He was able to answer all of our questions and we knew we made the right choice. Once the scope of work was determined and a date/time established he arrived on time and completed the work promptly and neatly. We are extremely pleased with Kevin's work. In fact we have other electrical projects planned in the near future and we will be reaching out to Kevin. For anyone searching for an electrician Kevin is the right person and I can assure you that you will not be disappointed."

"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 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.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

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.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.
