"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"

"Jason installed doorbells at 2 doors. There were no functioning doorbells when I purchased this house 5 years ago. Various contractors warned me of the difficulty and expense of hardwired installations, making me put off the project. Wireless doorbells were unreliable. I was encouraged by James, who did my annual electrical maintenance, and scheduled the work for me. Jason did a fantastic job by creative thinking to avoid the difficulties I'd previously been warned about. He did the job quickly, neatly, and very successfully. I am thrilled to have working doorbells for the first time in 5 years!"

Generator Install questions, answered by experts

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

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.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.
