"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."

"Michael came to my house and upgraded my 100 amp panel to a 200 amp panel for my solar installation project I had coming up. He was very thorough in explaining all the work that needed to be done, how long I would be without power, and was very knowledgeable in all of the questions I had. After removing my service and replacing it with the new 200 amp, he went through the entire house and checked what each breaker was wired to and marked it inside my panel very neat and organized. Couldn’t be happier with the experience from start to finish. If you need any work done to your home I highly recommend Mike and I will definitely be contacting him in the future if I ever need any other work done. Thanks Mike!!!"

Generator Install questions, answered by experts

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

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.

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.

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.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.
