"I couldn't be happier with Skyline Electrical Services! They installed a new electrical panel, EV charging outlet, backup generator inlet, and an outlet for a tankless water heater. The workmanship was exceptional, even better than the original installation, and every breaker was accurately labeled. Communication was excellent, and they kept me informed throughout the project. The crew arrived on time, worked efficiently, and finished everything in one day. They coordinated seamlessly with another crew installing my furnace, AC, and water heater. Everything was left clean and tidy. Skyline wasn't the cheapest option, but I feel extremely good about the price I paid. Considering the outstanding workmanship, professionalism, and attention to detail, I believe I received exceptional value for my money. I highly recommend Skyline and wouldn't hesitate to hire them again!"

"Benjamin Skinner did an excellent job of converting our old push button garbage disposal to a new “light switch” type. He also switched the circuit breaker to be compliant with current code. He’s a very good electrician."

"Starting with the sales process, Nate was informative and great. Could've sold me a more expensive replacement system, but instead identifies how my current system cod be retrofitted with a heat pump. That sold me on G&S right there. Everything from the initial install review, the office staff working with my lender, to Izaak and the install and electrical teams, was punctual, informative and professional. I've had several bad experiences with other contractors, but I would confidently recommend G&S for any job and plan to use them again for a generator switch install. Good people with a good business. Thank you G&S!"

Generator Install FAQs, answered by experts

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.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

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.

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.

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.
