"10 yr old Generac GP6500E wouldn’t start. Called around and many want to upsell to permanent. Found Franks and what a delight. Honest, down to earth, affordable for senior. Showed up on time. Changed oil, spark plug. Pulled carburetor and found it dirty and fouled. Got used one from his shop(same day) and installed. Gen started right up on one or two pulls. Battery was dead but showed us how to replace. Highly recommend Frank’s Generator."

"Hired HomePro Electric to install a transfer switch for a portable generator. Erik did a great job. Showed up on time. Did an excellent job and explained how to switch our electric panel from the grid to the generator really clearly. I will definitely hire him again for any future electrical work that I need."

"I hired Kyle to install the electric for my pool. He grounded the pool, installed an electrical timer for the pool pump, breakers for the circuits, and installed an outlet. I liked the quality of the work so much that I hired him to replace a GFCI outlet in my kitchen and an exterior outlet on my house and then hired him once more to install light fixtures. His prices are fair and his finished product is meticulous. If he tells you that you need something replaced/repaired he is not saying it to make money, he is saying it because the repair/replacement is necessary for safety or code purposes. I would hire Kyle again for any of my electrical repairs/installations."

"Triton electric truly deserves a five star rating from me. Triton first completed lighting work for exterior of THE GYM last year and it was done efficiently and exceeded our expectations on timing and professionalism. Over the last 2 months we have begun renovations and a new construction project here at THE GYM, Triton electric was our first choice. From the initial quoting of the job, to the installation, to the consulting with our architect and contractors, Triton has been extremely professional, communicative and reliable. Thomas’s whole team have been a pleasure to work with and we as a company would highly recommend and continue to use them for all of our projects going forward."

Generator Install questions, answered by experts

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

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

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

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

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.
