"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."

"Worked with the owner and couldn't be happier! He installed new lighting through out our home (34 to be exact) as well as new outlets, new wiring, and a new ceiling fans as well! He was able to install in a timely manner and more than accommodating to our schedule. He was professional and very easy to communicate with. I would highly recommend them and I am already thinking of my next project they can help with!"

"This company is exceptional in customer satisfaction. First of all, they were on time, courteous and completed the job with no issues. The equipment they installed was much better than the previous one. I now have a circuit breaker, which I did not have before. They worked constantly in the hot weather and garage without hesitation. The job was finished way before AES showed up to turn the power back on. One of the workers stayed throughout the remainder of the day waiting on AES. Once they showed up, he walked through the house to make sure everything was working properly and explained everything that was installed. He showed me pictures of the damage on the roof and, where he repaired it. He even hauled away the debris from tree trimming that AES done. This was way beyond what I expected him to do. I only wish I had his name, so I can mention him appropriately. I highly recommend this company to anyone seeking electrical solutions."

"Extremely happy with the service I was provided by QuickTime Electric. Had an issue with a water company running a screw through three sets of wires in my garage when they installed a water filter system and also needed my Meter box resealed due to the prior electricians poor installation. All this was well beyond my capabilities to repair and I had heard good things about QuickTime from a friend. They showed up on time and had everything needed to fix my wiring and Meter box issue. Once the repairs were completed, I looked over their work and was very surprised and pleased with not only the quality of the products they used but also their repairs and how they did them. I was expecting a significant bill, but when the bill arrived, it was half of what I expected. Given that money is tight these days, I felt like I had come out on top. Recommend the company to anyone that needs a great electrical company. I for one will certainly be using them again with any electrical needs I have in the future."

Generator Install questions, answered by experts

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.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

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.
