"B-Moore was the only contractor out of the Home Advisor list who answered the phone and returned my voice mail questions. Installed switch panel for the back-up generator and two outdoor light. Demonstrated the hook-up process and walked through the house to make sure the system worked. Price was fair, I checked with a friend who is a contractor, and the military discount is appreciated. They will be the ones I choose for the next electrical work. Polite, articulate, and skilled crew."

"Very responsive and professional on our first visit .Technician Charles Monday gets a five star review based on his thoroughness and professionalism .We have two old AC units that are not functioning well as they were installed when we moved to the house 21 years ago .Mr Monday came on time and spent hours in the attic taking care of a leak and cleaning the furnace and filters and motor ,and we are grateful .He explained each step and consulted with me and took photos to document the problems encountered .Whereas we are contemplating replacement due to the age ,we feel we got our problem taken care of until the nest step which is a replacement of our units .I was impressed with his knowledge base and how he took so much time in making sure the AC was in running condition when he left ."

Generator Install FAQs, 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. 

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency.
