"Jayson notified me right away and immediately scheduled an appt. He was very accommodating as to when I was available. When he arrived to my appt, he was nice and polite He was accommodating when asked to remove his shoes when going into me bedroom. He was very knowledgeable and kept explaining the issues that I had problems with. I appreciated his suggestions and thought his price was reasonable. I intend to call him again the next time I need an electrician and will gladly recommend him to my family and friends."

"Overall experience was average. First day of installation was okay until I find out half of the house did not have power. Edgar came back the next day and explained the cause and fixed it with ease. Was getting push back about how everything was installed as it was and there shouldnâ t be any issues, well there was and he graciously came back and fixed the problem. I would definitely use this company in the future."

"Joe is hard working, diligent, and honest. I hired him 1) to put up an antenna for local tv service and 2) to fix poor wifi signals. TV was converted from cable rapidly using leftover wires. Saving $ not paying for cable and streaming off wifi. Great signal strength! WiFi was harder. He worked with ATT to determine my new iMac was sucking signals. He installed a more powerful router that solved wifi issues when iMac is off. Now I have to work with Apple to figure out how to manage the computer searching. I would not hesitate to call Joe back again. He is an excellent technician and a fine person. He is pretty busy, so sometimes it takes a few days before he can come out, but he is worth the wait."

Generator Install questions, answered by experts

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.
