"It went fairly smoothly. They gave honest feedback on the existing fixtures (what needed to be replaced, what could be repaired). They didn't have an exterior fixture that I needed on the truck so I went out and purchased locally. They installed and set up the auto settings for an exterior spotlight. Indoors, they installed a new ceiling fixture in a hallway and diagonosed and repaired some recessed can lights in the basement. One of the two has since failed again, which was a risk I took to avoid a replacement. Looks like I will need to call them again!"

"Paul was fantastic! He did an excellent job installing 4 ceiling fans for us. He kept me updated on what steps were needed in each location (e.g., removing existing track lighting, installing a fan box, extending the wiring, etc.) and worked efficiently. Paul was also kind enough to explain things to me, which I really appreciated. He has been in the field for a long time and is a wealth of knowledge. I will definitely reach out to Paul for future projects involving electrical!"

"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."

"Very responsive, came out for a quote in a timely manner which I can't say many others did. Has responded quickly to my emails to answer any question I have posed. The crew came on time to position the generator and had it in place as described. As soon as Tim and Robert were notified of gas connection they scheduled final install, showed up exactly on time and completed work in a very professional manner. Very happy with the entire process."

"Michael installed bathroom vanity lights and ceiling fans in two bathrooms and added new outlets and switches. He also was able to fix an intermittent problem that I had lived with for years. The work was top notch, and when he spent less time than his quote was based on, he told me about it and took 20% off the price I agreed to. I highly recommend him."

Generator Install questions, answered by experts

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

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.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.
