"Gracen is excellent! I needed a transfer switch to run my generator from the electrical panel. From first quote to job done, Gracen kept in touch. He does good honest work and explains everything heâ s done. Heck, he even put up with my dog barking the whole time he was over lol. When he was done with the job, he helped me go through everything and in detail. Recommend highly"

"Those guys just terrific! They installed a whole house generator. It was a very hard installation, because the generator was far away from the electrical source. They have also followed recurring maintenance."

"We have nothing but great things to say about SLTD Electric. They have come out to our house a couple times now for different projects, and they are always very communicative and deliver affordable, prompt, and effective services. They are also super friendly (and sweet to our gaggle of pets). We cannot recommend them enough."

"Kevin called me the same day I posted the pro request. I scheduled him to come by to do a quote two days later and hired him at that point. Kevin replaced a scary exterior electrical outlet and power cord that powers a pool pump. The power cord was coming out of the ground and arcing and the old outlet was melted around a socket. Not good. Kevin fixed it right up and replaced and greatly improved the whole set up, including installing an exterior outlet and switch that are both protected by the weather. Very impressed and will hire Kevin again."

Generator Install questions, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

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

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.

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.
