"John was great initially - getting there and tackling the immediate problem and answering my calls. We had a short in the electrical heating fan/motor in the floor that was potentially dangerous and could have caused a fire so he replaced the breaker and rewired the fan/motor. However, when he left we noticed that the fan was not running in the box and he told us to detach the wires which I felt was risky and also meant the problem was not fixed. He said he would come back the following Monday to inspect the rest of the wires underneath the house and he never did. He was also supposed to send me a photo of the burned wires, a work order/receipt for my files, and never did. I texted him about Monday and about replacing the fan/motor - either to let us what it was called and we would replace it ourselves or give us the cost of replacing one or all 3 boxes. He never responded so we still have a heating system that is not fixed and perhaps dangerous if only running on two fan motors ."

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."

Electrical wiring or panel upgrades FAQs

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
