"I am very happy with the way the job was performed. Jamie and Jake had to trench about 100 feet from my home to my workshop, and then install 4-5 outlets and exterior sensor lighting. My yard is on a hill, so it wasn't a simple thing to trench and run the line, but they made it seem like it was easy. There were no problems, no unexpected new charges, and the job took 1-1/2 days. I will definitely use their services again."
A win for the owners of this panel change.
Ready to label and get inspected
This is guaranteed to provide adequate electric needed to provide heating and cooling on demand.
Panels are installed and look great.
Without yearly inspections of your electrical services in your home this could happen to you. This is the panel that failed and we upgraded.

"Called them 745 Tuesday morning. Outside temp about 0, so had to get furnace working again quickly. They arrived within 1 hour as promised. Breaker was about 40 years old, not repairable, had to install new breaker panel as old units not available for repair. Not surprised as I had heard this was an issue. They got parts for new full breaker panel, had old panel torn out and furnace back on by 2PM that day. Also had optional whole house surge protection installed for $500 additional above $1800 for breaker panel. 200 amp service."

"This was an electric upgrade for my FIL that is 84 yrs old and lived in a 71 model trailer. None of the other electricians wouldn't take the job. We were desperate to get this mans electric upgraded so that he could receive help for a furnace so he could keep warm during this cold winter. They were quick and got the job done. God bless them!"

"Cincinnati’s Everlasting Electric did an excellent job. They installed a new 400 amp service from the street and added some 220 volt lines for a car charger and cooktop. They were polite, did everything on time, cleaned up, and were very courteous. The inspection passed and the inspector told me that he never finds any problems with their work. I highly recommend them."

"Mr. Electric provided excellent service for me under difficult circumstances. A building contractor damaged a wire and buried it under 42” of concrete. Ryan Corley, Mr. Electric’s wire detection specialist, was able to locate the wire accurately. Electricians Jeff Shipkosky and Khefren Johnson spent two and a half very long days, in 93-degree heat, digging around the perimeter of my house. Both ends of the damaged wire were eventually located six feet underground, which is considerable deeper than code requires. Justin David, Mr. Electric’s manager, was here working alongside his men and provided all the support possible to them. He maintained full contact and communication with me throughout the entire process. These men, along with a crew of assistants, are a class act company. I was very impressed at the dedication of Mr. Electric and recommend them highly."

Generator Install questions, answered by experts

Generator installation in Hamilton typically takes two to three weeks from start to finish. This includes time for permit approval, site preparation such as pouring and curing a concrete pad, and actual installation. If a new gas line or electrical upgrade is required, expect a few extra days. Final inspections and utility coordination may extend the timeline, especially during winter or in historic neighborhoods.

Helpful?

In Hamilton, the electrical panel and transfer switch are often the focus during generator installation, especially in older homes where upgrades may be needed. Outdoor areas, like the concrete pad or foundation, require attention to withstand freeze-thaw cycles common in OH winters. Proper weatherproofing of exterior wall penetrations and safe routing of gas or propane lines are also crucial for reliable backup power and long-term performance.

Helpful?

After installing a standby generator in Hamilton, schedule a final inspection and inform your utility provider. Test the system under load to confirm seamless transfer switch operation. Regularly run the generator, especially before storm season, and check for debris or ice buildup around the unit. Keep a maintenance log, and have a professional inspect connections and fuel lines annually to ensure dependable backup power during unpredictable OH weather.

Helpful?

In Hamilton, warning signs like flickering lights during power transfer, delayed startup, or unusual noises from your standby generator should not be ignored. Persistent fuel smells, water pooling near the concrete pad, or visible rust can signal bigger problems ahead. If you notice voltage fluctuations, frequent low oil shutdowns, or excessive vibration, address these promptly to prevent more costly repairs and ensure reliable backup power.

Helpful?

In Hamilton, common mistakes include skipping necessary permits, misjudging generator size for their home’s needs, and neglecting proper grounding. Some homeowners overlook local setback requirements or fail to prepare the concrete pad for harsh winter conditions. Attempting DIY electrical work, ignoring ventilation clearances, or not winterizing the generator can lead to safety issues and reduce the reliability of your backup power system.
