"Sergio and his assistant installed an EV charger at my place, and they did an amazing job. I’m so glad I hired them. Their price was reasonable compared to other contractors. I highly recommend them and would definitely use their company again for any future jobs."

"Quinn was professional and courteous. In addition to the EV charger installation, he also installed 2 new circuits with breakers and new conduit. All the work looked amazing and he and his associate cleaned up everything when they were done. Couldn’t have been happier with the work done. Would highly recommend Quality Electric."

"Ricardo is the best electrician I?ve ever hired. Was very professional and friendly to talk to. Honest pricing for a meter panel upgrade. Did what he said he was going to. Also checked out some lighting fixtures I wanted to get installed in my home as I?ve had several quotes and they were just outrageously priced but he gave me the best price out of 6 electricians! Will definitely hire Rick for all my future electrical needs!!"

"They were great from the start. Setting up the appointment was easy. They let me know through text when the electrician would arrive. The electrician was very professional and was able to explain things to me clearly in a way I would understand. He gave me a fair price and there were no surprise charges."

Generator Install questions, 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.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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.

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.

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.
