"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"

"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

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
