"We called Mr. Electric to provide a quote for removal of existing and installation of a new light fixture in two-story foyer. They were very responsive and sent out a technician within a couple of hours to provide a quote. Once the technician arrived, he proceeded to complete a in-home survey of our electrical panel, exterior electric box and electric meter. He then reviewed the scope of work and came back inside within about 10 minutes. He went over the home inspection and then provided the quote that’s where things went sideways. The quote was $1169! 😳 Again, that is to remove an existing light fixture in a foyer and replace it with a more current contemporary styled one. We explained that the quote was excessive based on our estimates from other providers. He indicated that they had just revised their pricing and that their pricing was in line the other major electric service providers. Needless to say, we explained to the technician that we would not be going with their services due to the price point."

"Highly recommend this company. The owner called me on a Saturday afternoon to discuss my project after I submitted my request about an hour earlier on Angi. A technician, Carter, was onsite on Monday and was professional, courteous, and efficient. He serviced what I needed done, and the price was reasonable."

"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."

"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.

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
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.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
