"From getting an estimate and receiving the information related to the upgrade on my electrical panel based on having an older home which was grandfathered in. I felt more at ease and comfortable with the upgrade from Keil, the technician was professional and so was staff that provided the estimate. I would never hesitate on hiring Keil for all of my electrical needs."

"I’m very pleased with the bathtub replacement, Sheetrock installation, and painting work Cenarez Construction completed in my home. They were professional, reliable, and paid close attention to every detail. The bathtub looks beautiful, the Sheetrock was installed perfectly, and the paint finish is clean and even. They did an excellent job from start to finish, and I highly recommend their services."

"We bought an older house not knowing much about electricity, other than both of our vehicles are electric and need to plug in to charge. Long story short, we didn’t have enough electricity coming into our newly purchased home. We needed a complete upgrade. We got in touch in with Silvio and although what we needed was serious, he made it as painless as possible. He planned and coordinated everything. When the power company was there that morning to shut down the power, Silvio and his guys were there waiting with everything they needed. We had our power back on that very same day. They did a fantastic job at a reasonable price. Silvio kept his word and did everything he said he was going to do and we find that refreshing. 10 out of 10!!! Honest. Reliable. Trustworthy. Thank you SRM!!!! Definitely recommend and will use again"

Generator Install FAQs, answered by experts

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

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.
