"I had initially gotten a quote for the purchase and installation of my 22KW Generac generator from an electrician. He suggested contacting a Generac dealer to purchase and install my generator. Since I would have to contact a dealer if I had a problem with my generator after installation anyway, it seemed like a good idea. I got a quote from Trinity Generators which was substantially less than my previous quote. Getting the generator from Trinity was an easy choice. They did an outstanding job of installing the generator. Trinity handled all the paperwork and permits all the way to the final inspection of the installation. Trinity sent 4 technicians to install the generator. They started at 9am and finished right after lunch. The installation was fast and neat. They treated the installation as if my home was theirs. They removed all packing material and trash and left my home just as it was before they were there. I couldnâ t be more satisfied and happy with my decision to have them add a generator to my home. 5 Stars!!!!"

"Nick Murray, one of the Murray brothers, replaced a circuit breakers panel in the basement and installed a full house generator with switch panel on my house. Nick did a great job! Very professional and courteous. I would definitely recommend this company for electric works."

"Carlos is a PRO. Came out installed a new 200 amp electrical panel, conduit protected 200 amp line in, full bonding and grounding system, as well as ran a line and installed a generator interlock kit. He was thorough in showing me how to operate everything, the craftsmanship of his work was next level, everything up and running in a timely manner, and the cost was great. 10/10 would recommend for any and all electrical needs."

Generator Install FAQs, 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. 

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

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.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.
