"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."

"I needed a fan installed in my garage and Quinn came and installed my fan. He also changed out some plugs that were bad. He did a great job and I would definitely call Quality Electric again."

"This team installs and services solar installations which makes the quality of their work better. They see what breaks over time on other projects and bring this experience to their own. This is my third project with them. My first was servicing a short in my system caused by an oversight by a different installer who had gone out of business."

"Highly Recommended! We have hired Zero Electric to do several jobs at our apartment complex including installing a generator, EV chargers, new panel, and even installing recessed lighting in the units. They handled all aspects of the projects and had top notch communication throughout. The team has always been quick and professional. We will continue using Zero Electric for our electrical needs."

"The electricians installed two outlets and one LED light fixture in a very professional manner. They provided good advice and suggested that I consider rejunvenating my electrical panel as my home is now 26 years old without pressuring me to have it done immediately. I will definitely consider Trout Electric when I decide to have it done."

"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 are knowledgeable and installed the car charging station in my garage. I had compared with other companies who seemed to be cutting corners, and I felt McKee was doing things the right way so I chose them. His communication was good, he was on time, and followed through on what he said he would do. Good, clean, and professional. I intend to have him back out for my next electrical project."

Generator Install questions, answered by experts

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

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