"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."

"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

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. 

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.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.
