"Last Monday, Nov. 3, I had some major surgery done on my GENERAC generator. It was time for "Super Maintenance" and your service man did a SUPER job! His name is Joe and he did a great job servicing my machine. He arrived on time and went right to work. He changed the oil and oil filter, put in a new battery, adjusted the valves, put in a new air filter, and even cleaned the top of the generator. All this while i looked over his shoulder and asked questions, lots of questions. I am impressed with Mr. Joe. He is very knowledgeable about your products, well spoken, and easy to talk to. It took him less than an hour to complete his work, despite my constant jabbering. He's a KEEPER! Thank You Trinity, And Thank You Joe! Paul O Weller Trinity Client"

"So much YES!!! John called me back within one business day of my initial inquiry to give us a quote and explain the generator transfer switch install process. We set an appointment for which Bill showed up exactly on time. He was OUTSTANDING. He explained everything he was planning to do, answered our questions along the way, gave us status updates and even though our house wasnâ t the most cooperative, went above & beyond to put the transfer switch in a spot that was more challenging for him but more convenient for us. Top notch customer service. He walked us through how to work everything and simulated a power outage to ensure it was perfect. And it was. John Gambino Electric has new lifelong customers. Thanks John & Bill!!!"

"Troy did an amazing job on several projects for us. He installed a 220 sub panel box and wired in a new hot tub. Additionally, he wired up our basement during a remodel, same as a new construction build. We hired him back on for the project due to the professionalism and fairness he brought with him on his first job with us. I’m a meticulous guy and picky about how my electrical work looks. Troy came in above and beyond of what I was expecting with his order of neatness and cleanliness when laying his lines. Everything had to be perfect for him and I feel he exceeded what my high expectations were already. I would certainly only consider him for whatever our next electrical project is."

"I ordered a general checkup of my home. The electrician found a melted wire in my breaker box. He rerouted all of the wires to separate bolts. I opted to get a surge protector installed at that time. I recommend James at Mister Sparky. He explained the questions that I asked. Like, â  What is this switch for?â  Itâ  s a comfort to know that my home is safe now.... and that I have a switch to turn on electric candles in my windows."

Generator Install FAQs, 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.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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.

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.
