"I will start this review with a positive: they were prompt. Everything went downhill fast. I called for an estimate on the install and relocation of an electrical box for a wall mounted light fixture. The original fixture was a flourescent unit that was still mounted to the wall, however, I wanted to mount a new fixture and would need the wires relocated approximately 4 or 5 inches to the right (requiring a new junction box and electrical box). The two techs arrived and went to work in the bathroom. They closed the door. I should not have let them do that. Rookie mistake. They decided the best way to look behind the light fitting was to rip it completely from the wall (breaking it in the process) and to also leave hot wires protruding from my wall (thanks, now I don't have a working light and I have hot wires sticking out of my wall). Next, they had to look for a stud that may be in the way. Rather than use a handy-dandy stud finder that you can buy in a hardware store for about $10, they decided that the best course of action was to just hack away at my bathroom wall. They then declared with great pride: "yep, there's a stud there". I could have told them that myself without punching a hole in my wall. After that, they then informed me (with a straight face), that the cost of the job would be $600. I think you should be paying me $600. Thanks for wrecking my bathroom. Maybe consider a career in demolition? Just a suggestion."

"I hired this company to put in a generator after seeing their commercials on TV, and seeing all the high reviews online. I can say that my experience has been horrible. First off, the permitting process took months, just to get the approval to install the generator. After the install, city permitting workers came out countless times sighting issues that needed to be resolved that seemingly didn’t get resolved because they’d get flagged again for the same issues. The biggest being they installed the generator too close to the natural gas line, which caused them to move the generator over about 18 inches and needing to install a giant junction box on the outside wall of my house. Not a great look. During the install and clearing permits, it’s almost impossible to get ahold of anyone to get a status update. I’d call and leave messages, email – repeatedly – before I’d finally get someone to reply. Fast forward a year, I discovered they installed one of the junction boxes incorrectly to my pool heater, causing it to fill up with water… so another repair. Now after the first year they hit you with a $600 per year contract to continue to monitor the generator for issues. Even after I signed it, I still get an email asking me to sign up every couple of weeks.. I’ve responded a dozen times telling them I’ve signed up for the monitoring program and to stop emailing me. Now the icing on the cake. I’m paying $600 a year for them to 'monitor' for problems. Today we lost power and the generator didn’t turn on. Looked at my mobile app, and it shows the cell signal used to monitor the generator isn’t working. I open the generator and the control panel that runs the entire system is blank and not working. Obviously a major problem… and isn’t that why I’m paying $600 a year for Reliable to monitor for problems and fix them before they cause an issue? This monitoring program is a scam. If they were actually monitoring the system they would've seen that my generator didn't exercise on Monday as scheduled, and that I've been offline over a week! Calling to ask that question just got me on the line with some low level customer service person, who can’t do anything but set an appointment a week from now. If you’re going to install a generator, look elsewhere."

The Lee County division of AA Action Electric specializes more in commercial new construction and build out. We also do residential remodel and custom home new construction and both residential and commercial service and underground. The Charlotte County Division is geared more to residential new construction and pool wiring.
"This is the second time I have hired AA Action Electric and they did a terrific job. This time around they installed an interlock kit, generator breaker and power inlet, and also upgraded my NEMA 14-50 EV outlet with an industrial grade receptacle. At my request, the power inlet was installed in the laundry room to power up my battery inverter generator. Kenny and Andrew were on time, professional, fast and efficient, and friendly. The price quoted for the job was reasonable, and Chris, the service manager, was easy to work with, and the job was scheduled and carried out out within a week of my approval of the estimate. ."

Our locally owned and operated company has built a reputation for superior workmanship and exceptional customer service. Our experts electricians can help save you money on service calls and energy bills by doing the job right the first time. We are certified energy consultants and specialize in generator repair and installs.
"In May of 2023 I had a system installed. When hurricane Milton ? came through the system failed. Called for emergency repair. Was told for an upfront payment, a technician would arrive within 48 hours. Technician did not come. After repeated calls. I was told because of an over abundance of calls I was pushed back a week. Duke Energy restored power to our home before Genrex came by. Mind you the Generx is supposed to perform during emergency. Now to get a service for a annual check up, to maintain warranty. Was told my last service person used superior parts. Why would they not supply quality products initially? I am very unhappy with Generx. I will not recommend Generx. In fact I will strongly advocate against this company to family and friends. "

FAQs for generator installation projects in Marco Island, FL
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
