"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"

"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."

Generator Install FAQs, answered by experts

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

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.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

Many services include assembling the unit and securing it in the window. Confirm with your provider.
