At just 24 years old, I started “Zach Costa Electrician” with nothing but determination and the drive to succeed. After six years working for a large company, I was laid off — and decided to take the leap and build something of my own. Today, I run a one-man electrical business built on trust, high-quality work, and strong communication. Being self-dependent has allowed me to take pride in every job I do, while also spending more time with my family — the real reason I do what I do. Whether it’s an emergency call or a full home wiring project, I treat every customer like a neighbor and every job like it’s my own home. Wired with pride. Grounded in values.

"I hired Zach to install a couple of outdoor lights for me. He was very professional and knowledgeable. I also thought his prices were very reasonable. He made suggestions on what he thought would be the perfect fit for the project. He completed the job and I was very pleased with the results. I contacted him a second time to replace a ceiling fan and new lighting in my closets. He did a great job. I would highly recommend him to my family and friends."

"I hired Matt when I was in the process of converting from a natural gas wall oven and cooktop to electrical versions. There had to be a lot of rewiring done, and he and his men did a great job. They arrived promptly at the agreed time to do the preliminary work and then arranged to come at the same time as the appliance installers to finish the job. Matt even took the time to fix my doorbell for me when I mentioned that it had not worked for years :-) It was clear that they are incredibly competent and the job went very smoothly. I would definitely hire them again if I need electrical work done in the future. Thanks Matt!!"

Generator Install questions, answered by experts

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

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn’t ideal if you want to extend the life of your generator.

Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn’t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.
