Generx was great , they kept me informed throughout the whole process and answered any questions that I had. Once the permits were issued they had the generator and electric panel installed in one day and had me up and running . All the staff were very friendly , helpful and very professional. I highly recommend this company .

I was very impressed with their proposal, cost, and the quality installation. Excellent employees and project people. They did all aspects of the project. No need to have additional contractors. The cost included the initial supply of propane as well as other related fees. It made the overall cost less.

I scheduled Generx on 2 separate occasions to get my generator running. The first time there was an issue with gas regulation likely related to solonoid valve. Tech made a minor adjustment and got the generator running. A week later I tried to run a test and I could not get the generator running. Tech came back out and told me it was a problem with my fuel tanks. There are 4 tanks available to the generator. 2 large tanks that I rent and 2 gas grill sized tanks stored in the unit itself. Tech discovered that 1 of the large rental tanks was empty so switched to the full tank. Again, he got the unit running. When I tried to test the next time, the unit did not start. When I called to discuss with Generx, they told me I should call the gas company because they felt it was a problem with the rented tanks. I told them the unit did not start when using the small tanks either so calling the gas company would not help. I told them that I thought that the unit needed a part involved in the gas regulation. Then he said they don't usually work on small units like mine and they don't know much about them. A little hard to believe a small unit is harder to work on than a large one. If they didn't know much about them, they should not have agreed to attempt a repair. I paid $132.50 for the first visit and 87.50 for the second visit. Both visits included a disposal fee even though they disposed of nothing. The tech spent about 15 minutes diagnosing and "fixing" the problem. I would not recommend this company for repairs.

Good Day [Member Name Removed], We are sorry to hear that you had a difficult time with our service department. We apologize for not being familiar with your unique generator configuration. It is unusual to have so many small propane tanks hooked up to one small generator. During our return service request we found you to have simply run out of propane in one of the 4 tanks that was currently supplying the generator. Both times we left your residence the generator was running under factory specifications. We appreciated the kind words you expressed to our technician after the work had been completed each time. Our prices are always quoted over the phone previous to our visit.

After reviewing several companies, I went to the Generex website and filled out their online form to request an on-site visit and quote. I received a confirmation that the request had been received and that I should be contacted in about a week to set up an appointment. After about 10 days I had heard nothing, so I telephoned to ask when I might be hearing from them. The person I spoke with confirmed that I was on the list of people requesting a quote and that I should be hearing from a representative in about another week. That was at least 4 to 5 weeks ago and I still have not heard from them.

Hi [Member Name Removed]! I'm sorry! Our automated system system shows you as receiving an email 5/16/2018 at 5:14PM stating that you're a little out of our area. In that email was a link to the Generac Site to help you find a dealer closer to you. You were also asked if you would like to stay on our list for the future. No one responded. We would appreciate you updating this Angie's List Review.

This company provides amazing customer service! The sales team first sends out a welcome email along with informational videos on the generators, then calls for to make an appointment and answers all questions (not pushy sales tactics). When you place your order, you receive a detailed email on who, what, when the services will be performed (very helpful and considerate). The electrical & gas installations are done on different days by highly trained technicians who know what they are doing. They explain the process & time needed and they all bring levels to make sure their work looks great!! They take pride in their work! The last contact is with the "start-up" technician who goes over the systems to make sure everything works properly and provides additional information (one caution here, he's a Carolina Panther fan). Bottom line, I am extremely pleased with the entire process and confident in recommending Generx!

Can not get service from Generx after trying for 2 months.
Description of Work
Had 22KW installed via Ken Solmonson in July-Aug, 2017. At that time I gave Generx an A rating in all categories. Since Irma, and needing service on our generator after running for 200 + hours, I was informed that I should have service on the unit ( via Ken Solmonson ) who said on 10/4/17, that it would be a couple of weeks for service. Today is 11/27/17 and I now understand that Generx southern office, of which Estero is in, no longer exists, Ken does not work for Generx anymore, and their main office says that I should get another company to service the generator; also asked about our warranty with Generx Company, and C at main office said she did not know and would have to check on that. Therefore as of today, GENERX certainly deserves an F

The follow-up to repair the drywall in the back hall (still not done) was the only thing from making this all A's. The generator came on immediately after we lost power, ran for five days, and the natural gas bill was way cheaper than one night in a hotel. A little better coordination between subcontractors would have made this a perfect score, but I feel the initial and operating costs of the unit make it a great deal. And my neighbors who used the freezer and pool agree!

A year ago, we had a whole house generator installed at out new home. We love great customer service but we never expected the amazing service that GenereX Generators provides. From beginning to end it was seamless. when we signed the contract, Mark Costis, Owner/Operator sent us a letter that he was totally involved in everything and if we have an problems he wanted to know. Each and every one of his employees, from sales to installation professionals loves working for this man. He may well be the "most loved employer" LOL! GenereX kept in touch with us during the hurricane even offering a means of contacting them directly. Our online app let us know that our generator was ready, but had not gone on. After Irma passed, again we heard from Mark just to make certain there were no issues. So... this company is amazing !!! To: Mark Costis, Owner/Operator "Thank you for this communication. As always, your interaction with your clientele exceeds our expectations and sets a standard that few, if any, meet! Your commitment to all of us and may I say, your employees, is outstanding. Your employees truly love working for you and as you may well know, they, in turn, are happy in their jobs ! "

Their reply to my request essentially made it clear that unless a definitive issue was found to support that the previous service was to blame for the transfer failure, I would be charged again. Needless to say, working outside in the middle of a hurricane on a generator that I am not familiar with while winds are blowing tree branches all around me is not what I call the generator being repaired.
Description of Work
Original service to whole house generator went well. Oil/filter/plug change. Had a transfer issue where the generator was running but would not auto engage to power the home. Thought issue was resolved however during Hurricane Irma, our power went out at approx 1am, generator kicked on but again as before the "service" the transfer did not occur. I was able to manually engage the transfer in the middle of the storm with the help of a family friend who actually is employed by Generac. Following the storm, we called Generx and asked that they actually fix the issue at no cost as it obviously was not resolved from the initial service.

Mr. [Member Name Removed], i am sorry to hear that you were not happy with the response you received from our service department. Yes, GenerX was at your home approximate July 26th, 2017 in which we preformed a basic service to your 20kW Generator and as well as reset the controller as wire 23 was not switching to ground. Versus simply installing an expensive controller, our technician Stephen reset the controller and all systems were operating as intended prior to leaving your home (as verified by you) and therefore saving the labor and the expense of simply installing a new controller that my not have been necessary. Since the controller reset and you experience further problems it may be very possible that the controller may have an internal failure and further diagnosis may be required. As our service team explained to you, if the new repair had something to do with resetting the controller for you then the service call on the next trip would be waived. Although any additional parts and labor you may need would not be covered. We would have been happy to come out and see what new situation had occurred, yet there would be a standard service fee involved that would cover the first hour of diagnosis to see what more would be needed to repair your generator to proper operating condition and again any additional parts your generator may need would have been the responsibility of the customer. If you would like us to return and further diagnose the problem, please fee free to contact our service department. I am glad you were able to preform a manual transfer of the switch which you were able to have power during Irma when needed. Thank You, Greg Hoerner V/P GenerX Generators Inc.

Simply outstanding. They installed the generator quickly and kept up on maintenance so when power was needed after Hurricane Irma it worked. It was nice to have hot water and air conditioning when the rest of the neighborhood was out of power. Can not thank the Generx enough!!

We were hit by Hurricane Irma here in Dunedin FL. Our 20kw Generac ran continuously on natural gas for a 6 ½ day grid power outage, operating all electric systems – lights, refrigeration, A/C, cooking, electronics… even keeping my electric- dependent saltwater pool system operating, with only 1 momentary, minor voltage dip (I only noted as my Uninterruptible Power Supply block beeped once). I was uncomfortable stopping the unit while it was running as it was critical to my home and personal safety, but I visually checked it regularly and monitored for any yellow light warnings which did not occur. After grid power was restored, I checked the oil and added a quart of synthetic that I had discussed with the tech at the last annual service call. The next day, contractor crews had to cut the Duke Energy grid power to do additional repairs and the Generac kicked in and off automatically once again. I consider that service over 7 days exemplary with a 4 year old unit that has received regular maintenance. We bought the model #6244G 20kw residential unit from GenereX here in Oldsmar FL in June 2013. They installed and tested it including the automatic switching box. It has worked in previous outages perfectly starting, switching on and then switching off when grid power returned. They worked with me to place it along my equipment wall on the north side of the house and coordinated installation with building inspectors. GenereX appears to be a quality Generac dealer, regularly communicating with me as a customer and as we have had them do regular maintenance annually. They have been helpful on those calls answering my questions on operating and monitoring the unit including coaching me on the synthetic oil they use. GenereX responded promptly on a recall issue a few years ago and on a minor gas supply issue after we replaced an adjacent gas water heater unit. Also, with all the calls about generators GenereX received in the wake of Irma, they set up a special phone number for existing customers to get through with their requests. I did not have to use the number, but it was great they sent an email to me as a customer noting the special number. That’s good customer service. Thanks, again to Generac and GenereX JH – Dunedin Fl
