Gen Ready, Inc., was established in 1979 to service the surrounding area and provide residents with all their standby electric power solutions. Our staff of knowledgeable and dedicated professionals take pride in providing outstanding, personalized service to our customers and our community. All of our techs are factory trained and certified for warranty repair and maintenance. Call us today and become one of our many satisfied customers. You can visit us online at www.getgenready.com

"After getting several quotes, last year we hired GenReady to install a house generator. Ed, the owner of the company impressed us from the start. He was knowledgeable and patiently explained the process as well as answering our questions. We knew right away that GenReady was the company for us. Lindsay kept us up to date as we moved along in the process. Our generator was installed last July. Andrew and his team installed the generator with expertise and efficiency. They took care to leave our house and yard spotless. Lindsay and Andrew were always happy to answer my questions and address me concerns. We’ve needed the generator only once (thank goodness) when our power went out due to a necessary power line repair after a car crashed into a utility pole on our street. When the power went out, our generator turned on within seconds. Our house was up and running for the four hours the line repair took, and if it weren’t for the blink of lights, we never would have known our generator was running. Every other week, our generator self tests for a few minutes giving us peace mind that it will be here for us if and when we need it. Just like the generator, GenReady is a company that runs efficiently and seamlessly. Just today, Lindsay called to tell me someone would be coming tomorrow to change the oil which reminded me that I am long overdue in submitting this well deserved rave review. Thank you to the entire GenReady team (and to Great White Propane) for all you’ve done to help us know we can weather any power outage."

Generator Install questions, answered by experts

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

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.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.
