"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.

From a young age I always loved Electric. My father was my idol and owned his own Electric business. I rode around with him in the truck doing service calls and installations until I turned of age to officially work for the company. At 16 I started doing prefabrication for all the large projects. Once I turned 18 I was an official apprentice. Putting in numerous hours I became a foreman and was offered a position in Colorado building multi Million dollar houses. I came back to Ohio and opened my own company. With over 15 years of experience, not only do I provide Top Notch work, but I provide a professional long lasting relationship for years to come.

Generator Install questions, answered by experts

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.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

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.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.
