"Mike Powers responded to my query within seconds. I hadn't even had a chance to create my Angi password yet. Unlike other contractors, he gave me a quote within a week. (One contractor came out twice, then never gave me a quote or answered my follow-up emails. Guess he didn't want my business.) The biggest delay was obtaining the generator I wanted, a Kohler instead of a Generac. But everything was great on Mike's end. His electrical crew was thorough and efficient, as were the sub-contracted plumbers. Now, I just hope I have no need to use it, although I am confident it will work."

"Guys showed up on time and quickly diagnosed and fixed problem. While here we discussed she and load on house panel and had them install a whole-house surge protector. I had a post house get toasted by a lightning strike so seemed prudent given electronics in house."

"Installed a ceiling fan in 30 minutes. Informed me that the previous ceiling fan installed by another electrical company was installed without all the screws and the ceiling fan was the wrong type for a slanted ceiling fan it was a dangerous situation for me. He was courteous, prompt, competent and professional. He does maintenance work also and I hired him for some other projects"

"We had a panel swap out. Bryan was quick to respond to my inquiry. He had to involve AEP and the city inspector on the day of the install. They did a great job and were very quick! I highly recommend anyone in need of electrical work to contact Steller Electric."

"Scheduling with Breeze was super simple and they were able to accommodate my busy schedule. My technician was polite and was able to trouble shoot errors that a previous electrician made. I wish I had used them to begin with. The Generator was Installed in one afternoon too! As for pricing I thought they were average. You get what you pay for though, they do quality work so I donâ t mind paying a little more. Less headaches in the long run!!!"

We want you to know that we are very pleased with the quality of service Undefined Heights Electrical & Data LLC provided. I was impressed from our first appointment. Your estimate was not only the most affordable compared to the other four companies I received estimates from, but it was the most detailed. I really appreciated the time spent on educating me on your solution for our electrical work needed. This made me understand the process and reasons of the work that needed to be done. I felt confident I was making the right decision.

Not only were you the most affordable and offered the best long term solution, but you saved me money by being honest and not adding additional unnecessary costs. You also went above and beyond by adding a few extras that made my life easier. We sincerely appreciate your responsiveness and the way you conduct business. Your team completed this project on schedule. They were extremely professional and diligent during our tedious project. I was also surprised by how hands on you were, and it was a pleasant surprise to have you on site.  

I admire your tenacity, I?m still shocked at the fact that you worked outside during a sever e thunderstorm to get the job done on time.  This was a complicated job, you understood the sense of urgency and you were efficient enough to get it done in a day. Inspection passed with flying colors.

We will be recommending Undefined Heights Electrical & Data LLC to others because of our satisfaction with your service. We look forward to doing business with you for years to come. Undefined Heights Electrical & Data LLC is officially my go to company for any electrical issues I encounter for my primary residence and investment properties.

Generator Install FAQs, answered by experts

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

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.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

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.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.
