"Anthony and his team do expert electrical work of all kinds. We are a 145 year old non-profit organization with buildings and grounds, and have contracted with Technician Engineers Group (TEG) on two large projects (and several small ones) over the last 15 years. One project rewired a large 125 year old building listed on the National Register of Historic Places, and one installed an extensive outdoor lighting system. In these two unusual situations TEG worked closely with us to find innovative solutions to our unique needs. We are very pleased with the results, enjoyed their can-do approach, and highly recommend this company for any electrical challenge. We found TEG reliable, honest, on time, and all the work was completed ahead of schedule."

"Callahan worked me in during a busy week before the 4th even though it was a cold call. I did not know him.. The electrician was exactly on time at 8AM and he wore a mask. He did a perfect job, and went out of his way to make the wire out of site as it was installed across my garage.. Even though it took a little longer than anticipated, he still charged me the quoted price.. I will definitely call him again for all my electrical work."

"Supreme Electric was great. They showed up on time, worked quickly and swapped out the cheap plastic electric boxes and installed the ceiling fans we provided all while cleaning up and leaving no trace. I've had bad experiences before, but this was far different. We are very happy that such a small job was done promptly and done well. That can be hard to find these days. We will definitely hire again as we still need a few things done."

"Pete Definbaugh and his team installed the Generac 20 KW Generator and it passed the Harford County Inspection with flying colors. Pete organized everything to include with the plumber and county inspectors as well as BGE for the gas hook up and BGE's final hookup. The generator has a great transfer switch that kick right over and he installed TWO new grounds for the setup. He paid attention to all the details and that included making sure we had Harford County Approvals and PASSED inspection results. The workmanship of the installation was high quality all the way and it worked right during the test without a hitch."

"Very courteous folks to deal with. They replaced the battery in my generator, so I really can't comment on the quality of their electrical work. I was a little surprised by the amount of the bill ($255.00). but that is the hourly rate for electricians these days, I guess."

Generator Install FAQs, answered by experts

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator.
