"Jeremy is an incredibly efficient, kind, and hugely capable electrician. He spent the day at our house with his helpers installing a generator, and he dealt with every single problem that came up cheerfully and efficiently. I would highly recommend him to anyone for any size job. He makes himself available for any problems and is just overall a terrific person, who is extremely good at what does."

"We first called Cawiamca to see if they could repair our old split system. The guys cane out the same day. Unfortunately, the old system is was quite obsolete and it just wasn't worth repairing. Ron got us a quote on a new system immediately. Within a few days we had a whole new system installed! Price was reasonable, the guys all were pleasant and professional. We are way more than pleased with the outcome! And we wouldn't hesitate to recommend Cawiamca to anyone!"

"I hired Elevate Electric to install multiple electrical outlets in my basement after a waterproofing project. Kyle installed electrical outlets, ran a new circuit, and upgraded a breaker. The result looks outstanding! The new circuit wire is routed cleanly and he even dressed up some previous wiring too. Kyle shaped conduit around existing items along the basement wall making the whole utility room look good. This is probably the 4th time I have hired Kyle for electrical work. He consistently does great work. The quality is top notch and his pricing is extremely fair. You cannot go wrong with Elevate."

Generator Install FAQs, answered by experts

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

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.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.
