"It was pretty rocky. At first. Several appoints made by Tri-State no one ever showed up.Crew showed up to install the Generator before the site survey and did not have necessary equipment or cooperation of Electric or gas company nor call before you dig had been notified. I called Tri-State to warn them the call before dig had never been preformed. They said they'd take care of it, did not happen until right before installation crew came back the second time. The first time they were here they could not have installed the generator even had they had all the parts because none of the utilities had been marked. Finally after about three months the Generac was installed and working. I had several questions that I could never get answered by calling Tri-State. One of the installation team had to come back a couple of weeks later to replace a damaged part and he answered all my questions. The guys who installed the Generac were great, the problem is your guys operation center and call center as far as I can see do not communicate very well. Anyway the generator has worked fine in several power outages this spring. I am happy right now but I live in dread something goes wrong and I have to call Tri-State for help."

"What an excellent team of employees they have. They had to redo our electrical box, install electrical outlets, hang fans and run electric to our up stairs. Very professional company! We had another company to do it the first time and Freedom came in and redid it all. Their service is outstanding!"

Generator Install questions, answered by experts

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

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. 

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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.
