"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."

"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."

"They did a great job! I had 3 outlets in my house that sometimes worked and sometimes didn't. Unlike a prior electrician I hired who told me "there was nothing they could do"... the team at Broad Ripple Electric took the time to investigate the situation, and find the source of the problems, and fixed the issues. They also were able to update my antique doorbell - they installed a new working doorbell while retaining many of the antique parts (for aesthetics) to the old doorbell. They were more than happy to explain to me what the problems were and they were able to come up with solutions that were affordable and of quality. It's clear they are very knowledgeable, and they also cleaned up after their work and were respectful of my house, my time and my loud barking dog!"

"These guys were really great. Easy to deal with. Good products. Professional installation. Great follow up. I had gotten a coupon for an AC tuneup from another company at Home Depot. During the tune up they told us we needed a complete new system. He quoted us a price of almost $10,000. So I went to Costco, which has a local partner for HVAC. Surprisingly, they proposed a bigger, even more expensive system for $11,000. I was pretty frustrated. So I went on here, looked for the highest rated HVAC companies and found the great reviews for Complete Comfort. They lived up to the hype. They suggested a system that was similar to the other two proposals but MUCH cheaper at $7,000. Their guys came out in a rainstorm and worked their butts off all day. The new system is GREAT! Then after about a week we noticed a banging noise when it came on. We called and they came right out. They made an alteration that fixed the problem at no additional cost. It was such a great experience working with them all the way around."

Generator Install questions, answered by experts

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

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.
