Customers say: True professional

"We needed work done involving three different trades and were hoping to find one company that could complete all aspects of the job. The work included sheetrock replacement (including texturing to be paint-ready), laminate flooring & padding installation, and bath vanity install & connect water lines. We received estimates from four different companies and chose Armando Espinoza Villa Handyman. Armando came over to see and discuss the job and provided an estimate later that day. He has a calm, low key demeanor and did a good job of listening to what we needed done. His pricing was fair, and he has experience in all the areas involved in our project. He also has many very good reviews on Angi, which was a factor in hiring him. Additionally, we Googled his company to see photos of his work. Armando completed all of the work on our house in just over two days. His work looks professional and we're very pleased with how it turned out. We'd hire him again. We've included photos."

Generator Install FAQs, answered by experts

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.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

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.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

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.
