"We had a fine experience with these folks. Our house is old (1939), so all electrical work is challenging. They relocated a 220v outlet (which required work in the crawl space), added another 110v outlet, upgraded an outside outlet to GFCI, installed a new doorbell and a new ceiling light to replace an old one that was failing. Everything was done well and professionally. We ended up with a callback when one of the outlets needed to be relocated â and they responded promptly and efficiently. They came promptly, as scheduled, worked unobtrusively, and cleaned up effectively. Strongly recommend them."

"Carlton and Tony were extremely professional and knowledgeable. They diagnosed the problem immediately and found where the electrical problem occurred, and why it occurred. They fixed the electrical issue immediately and recommended new GFCIs be installed. They were both great and very friendly, explaining why the outlets were wired in the circuit in the layout of the area in the house. I would whole heartily recommend this company and these two gentlemen for any electrical work."

Generator Install FAQs, answered by experts

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.

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.

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.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
