"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 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. 

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.
