"Through the sales process they painted a beautiful picture. I dont believe the lowest price is always the best deal. I price compared two companies, Reliable was a bit more money but I liked the salesman and I believed the picture he painted. So much for "reliable", they are nothing of the sort. Horrible customer service and zero support after the sale. Run to another company as there are several others in the area to chose from."

"Technician, Samuel Ramos, arrived. Immediately quoted a $206 diagnostic free. We argued. He finally agreed to provide the free estimate originally offered. We needed him to look at the electrical/fuse box of the AC outside. He asked to see the electrical breaker box in the garage as well. After removing the cover, he gave me a scare with alarming observations of the wiring as outdated and dangerous. The fact that the AC had been installed and the box inspected by the county a little over a year ago was of no consequence. I was informed by Samuel the box was also too high and would have to be moved, possible outside! He would have to replace the box, which with the addition of 5 smoke detectors now required inside the house to meet code by the county will cost $14,600 to $17,194 depending on which of three options I selected. After he left, I discovered he failed to replace the cover of the electrical box correctly leaving wires exposed. His office assured me they would reach out to him. They have stopped responding to my texts. That and his failure to address the fact that he was not wearing a mask even after I told him I was diabetic and could not allow him into the house without a mask, I cannot contract with a company providing this low level of service."

Elcon Electric of South Florida has been providing homeowners & businesses alike with expert electrical services for over 35 Years. We've built a company of highly experienced, certified electricians to serve your electrical needs. There's plenty of competition throughout South Florida, but we make it our policy to treat our customers the way we would want to be treated. That has gained us a great reputation. We'll provide you with quality work at honest prices.

"What a mistake I made in hiring Elcon. Their estimate was 25% more than my other estimate from a licensed well-reviewed electrician, but I went with Elcon because I thought hiring a large company would help ensure things went smoothly, efficiently and give me some peace of mind. Unfortunately, the result was just the opposite. There were two fairly simple jobs. The first was to install an outlet on the opposite side of drywall where there is already a switch. The electrician took out the switch where you can clearly see the other side of the wall yet he still cut right in front of the stud exposing over 4 inches of stud. Why he didn’t use a stud finder or drill a small hole first before cutting completely baffles me. He did fess up to it immediately and patched it, but never even apologized. I had to match/buy paint to match the wall and cover the patch. Next he installed a non-GFI outlet in a laundry room which is against NEC code. When I informed him that the outlet was not to code, he said their estimator didn’t put a GFI on the quote. Yet I specifically requested a GFI outlet in my email to them - both in writing AND in a photo of the job. Why neither their estimator nor their electrician followed NEC code was concerning, but he did switch the outlet eventually. The other job was to install an outdoor wired box which was clearly titled as such on the quote. When I showed the electrician where the box was to be installed, he said he didn’t have a box with him. How he did not have one of only two fixtures needed for the job is beyond me. Also, instead of going to get the box before starting the job, he did it after the wires were threaded and exposed. He was gone for 40 minutes when there is a Lowes right next door to me. If it had rained, all of my entire pool wiring (which he wired up to) would have gotten wet. I paid him in full and contacted their office via email to explain what happened. Their office manager did apologize, but her unhelpful solution to my wasted time and extra money I had spent to paint was to schedule more time with me so their estimator could “spot check” the electrician’s work. Now, not only does their lack of trust in their own electrician make me worry about the completed install, but this would have been the third time I had to take time away from work and for their convenience. This is because instead of using the detailed request and photos I sent them of the job, the estimator still wanted to see it in person. And when the estimator arrived, he asked questions that were already in my request and took the same photos I already sent. When I finally pointed out that it was all in my request and photos, he then looked and was surprised it was all already there. Thankfully, I only scheduled Elcon for two of the four jobs they estimated for me. I was going to schedule those at a later date but after this experience, I decided to hire another company for the remaining jobs and will be sure to have them check all of Elcon’s work."

FAQs for electrical wiring or panel upgrade projects in Key Biscayne, FL

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
