"David quoted us a great price for the install. Dustin came out a few days later and did a great looking install and even mounted my charging unit on the wall for us. I recommend Andrew's Electrical."

"Mr. Electric was a dream to work with. I called them out to fix another contractors work. The day of the appointment, Mr. Electric sent me a text with a bio and picture of the installer (Kenny Lawrence). Kenny arrived on time and gave me a quote before any work was done. Kenny was very knowledgeable and personable. I felt very comfortable and I was confident that the work would be done correctly. Once the work was completed, Kenny gave me the bill and it was identical to the quote provided before the work was done. There weren’t any additional/hidden charges. I would highly recommend Mr. Electric for any electric needs, especially fixing another contractor’s poor work. :) Thanks Kenny!"

"Very clean and professional. Roger and his team did an excellent job. We were installing canned lighting in our kitchen and front. Roger spent time with me reviewing the best locations for the lighting as well as the switch locations. Best of all, he did not leave me with a dry wall project when they were done. Will hire again."

Generator Install questions, 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.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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.

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. 

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.
