"Walker Electric did a great job each time I hired them. On separate occasions they installed two ceiling fans, installed an electric outlet, and finally installed a full house generator. I will have them out again when there is need, and recommend their service to family and friends."

"My husband and I recently had a large detached garage built in our back yard. We were having a hard time finding an electrician. We found Stickler's Electrical Service on Angi and we are very pleased that we did. Anthony Stickler is a a true professional and highly skilled at his craft. He installed all of the wiring, outlets and switches, as well as the panel. He did a phenomenal job! He is prompt, responsive, reasonable and honest! Highly recommended!!"

Customers say: Quick response

"One of my rental homes needed electrical attention before an inspector would agree to come in. It was an emergency situation and Matt was very helpful. I originally called him after hours and was pleasantly surprised that I was able to talk to him. He patiently listed to my situation and came the next day first thing in the morning. He performed the requested work I needed. Then, worked a miracle and managed to bring the inspector the same day. Not only that, but he also called Duke Energy so that they would turn the power on the same day. I was very impressed with how reliable, honest, and prompt Matt was, and all for a very reasonable price. I will definitely call again if I am in need!"

Generator Install questions, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

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.
