"When I made the request on Angi's List, Gonelectrical called me within seconds. We talked about installing a whole-home surge protector. I traded some photos of my panels and received a quote over the phone. The job was scheduled for the next day. They showed up promptly and completed the work professionally. They explained what they did and showed me exactly what was done. I would recommend this company for similar work."

"I have zero complaints about this company. They came out very quickly to access my issue. It was urgent. From Oncor and this company, I clearly escaped what could have been a major fire. These guys were so professional and kept me in the loop of everything being done. I've saved their number for any future issues and I will definitely recommend them to anyone needing a skilled electrician. It was worth every penny to have it done professionally and safely. Thank you ALL."

Generator Install FAQs, answered by experts

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house 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.

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. 

Costs range from $500 to $2,500, depending on generator type and installation complexity.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.
