"Joe is hard working, diligent, and honest. I hired him 1) to put up an antenna for local tv service and 2) to fix poor wifi signals. TV was converted from cable rapidly using leftover wires. Saving $ not paying for cable and streaming off wifi. Great signal strength! WiFi was harder. He worked with ATT to determine my new iMac was sucking signals. He installed a more powerful router that solved wifi issues when iMac is off. Now I have to work with Apple to figure out how to manage the computer searching. I would not hesitate to call Joe back again. He is an excellent technician and a fine person. He is pretty busy, so sometimes it takes a few days before he can come out, but he is worth the wait."

"Did a great job, even corrected some code violations that were present when we moved in. Installed multiple 110v, 230v single phase, 230v 3 phase and 480v 3phase circuits, wired a paint booth, Tumbler unit, overhead crane systems, and even did some repairs on a complicated piece of machinery that wasn’t working. Great guys work hard no excuses. They get the job done plain and simple. I had used them twice because they were that reliable."

Generator Install FAQs, answered by experts

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

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. 

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. 

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

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.
