"Andy did a great job on wiring a new building as well as adding cat 5 wiring to my existing home. He worked around some challenging access issues for the cat 5 install and made sure everything was working before he left. The quality of all the work was outstanding. He provided some good advice in one aspect of the install in the new build, helping me avoid a costly mistake. He was very friendly, timely, and easy to work with. His prices were entirely fair. I 100% recommend Andy!"

"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

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

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.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.
