UPDATE 3/31/2026: The tech was supposed to be at my house at 8:00am, so I didn't burn a whole day of work again. I told them I need to leave my house by 9:30am to open my store at 10:00am. I get a text at 8:30am telling me the tech is on the way. I call in and talk to sone guy, and tell them he was supposed to be here at 8:00am, and was told he's still about 45 minutes away. The guy on the phone said he didn't realize I was in EST. I made the comment that it's always an excuse with them, his response was, "This is the 1st time I've talked to you."... True but I've spoken with many there, and they always have an excuse. I am given a choice, either wait or cancel. The arrogance of the guy on the phone, I told him to cancel, and I'll find another company to fix my generator. ------------------------------------------------------------------------------------------------------- UPDATE 3/26/2026: The tech was supposed to be here yesterday (3/25) afternoon. Never showed up, but I did get a call at 8:00pm to let me know that he wasn't going to make, but I would get a call from dispatch tomorrow. Received the call, and was told he was on his way. I'm sorry, some of us have work, and can't drop what we are doing to be at your beckon call. They rescheduled for Tuesday (3/31) as the first call... He is supposed to be here at 8:00am. I'm not holding out high hopes... We'll see. ------------------------------------------------------------------------------------------------------ UPDATE 3/20/2026: I guess they are going come out next week to double check that there's an issue. Wow... Let's hurry up and wait to get the issue with my very expensive whole home generator. I have no idea if or when it will be fixed. ------------------------------------------------------------------------------------------------------ UPDATE 3/16/2026: They finally came out, and needed to order a part. That was 2 weeks ago have not heard from them. I had a power outage last night, and was standing out in the rain and wind at 2:00am to manually turn on my generator. Then I had to take the panel off this morning to manually flip the transfer switch back to city power after I turned the generator off. The original issue happened on Jan 22nd, and it's now March 16th. I'm coming on 3 months of not having a properly working system. I just hung up with them, and they said they are waiting to hear back, and will call me tomorrow. At this point I wish I could give them less than 1 star. ----------------------------------------------------------------------------------------------------- 3 weeks ago, my generator turned on, and it transferred over to generator power. I never lost city power. The power company came and tested to make sure it wasn't on their side. I called Cove to come out and figure out what is going on. I was transferred to another company called Pioneer, and was told it would be 2 weeks before anyone would be able to get out. I ended up having to pay a local electrician to figure out what was going on, and get me back on city power. The cold and snow hits, and I get a text from Pioneer, that they are cancelling my service, it's going to be the end of March when they have time to come out and service my generator. Then a couple of days later I get a text that they have opening s at the end of Feb. There was no contact number, and no indication that I can respond to the text. I just took a call from Pioneer to see if I still needed service. Yes, because my generator is still broken. When I originally called, I'm not sure she understood that things were broken, and that the maintenance call was just an add on while they are here. Now that I've hung up with her, I'm not sure she still understood that my system is broken. If I hadn't paid out of my own pocket I would have been on generator for well over a month waiting for them to come out and fix my generator. This is a complete and total failure in service. After they come out and fix the generator, I will be looking for a new company to take over my service contract. read more

We just bought our house in the area and the house had a whole house generator. We had Cove Generators come out to service it as we did not know when the last time it was serviced. Good thing too because it needed a new battery. They were very helpful in going over the generator with us and answering all our questions. We also signed up for their yearly maintenance and monitoring service. We needed to call them for something (I don't remember what) but they were really responsive and quick to come out. We highly recommend Cove Generators, and we have to our neighbors. They are honest, quick in responding to customers and genuinely nice people. They have great people working for them and we would trust them for any of our generator needs. read more

During a recent power outage, our generator failed to kick on. My husband was able to fix that easily, but we decided to schedule service. Cove Generator was responsive and arrived as scheduled. In fact, the tech called to let us know he was 10 minutes away. The technician was courteous and did a fantastic job. Pricing was very reasonable. We will use them in the future and highly recommend them. read more

This people stole $4000.00 of my money! All they did was give me an estimate! No service, no generator! I called the next day, (after the estimate) and said we weren't interested in a generator at the time. This company of thieves robbed me of 4K and refuse to give it back! Now I have to sue them! so yourself a favor and do t do business with these crooks in Cookeville, Tn read more

Buyer Beware...I purchased my generator from my local Lowes in January 2020. Cove Generators was their recommended contractor for the installation. The install process for my generator was long. It took all day and part of the evening to complete. The generator has been trouble free since it was installed. The problems started when Cove did not schedule my maintenance service as agreed. The agreement was that they would NOT perform ANY service without my prior authorization. The owner, Janet, confirmed this fact after I called (January 2021) to determine why I had received a totally unexpected and inflated bill in the mail. After a brief discussion and Janet's acknowledgement that Cove's service prices are significantly higher than the other service providers in the area, she graciously offered to give me time to pay the bill. I declined her offer but again balked at the higher than average cost. Janet then offered to reduce the service charge to match what one of the other local service providers normally charge ($150) to compensate for their error of coming onto my property AND performing a service that I never authorized. I accepted and immediately sent the agreed payment amount; totaling $200 ($150 Service + $50 Monitoring). I lost my monitoring at the beginning of March for non-payment after Cove received their money in early February! Janet did NOT honor her offer! Upon further investigation it was discovered that Cove Generators put the ENTIRE $200 into their pocket, even though the original service charge (before Janet's discount) was only $190. I had left numerous messages requesting Janet to call me to work this out, but had not received a call back. On my last call to "leave a message for Janet", I finally reached her and was yelled at, berated, called names and told to "not call again" because "they don't owe me anything"! Janet would not let me get a word in at all. When she was done speaking, she hung up on me. I have never before dealt with a business that behaved as childish and unprofessional. The simple fact that Janet and Cove Generator didn't, at the very least, immediately reach out or refund the "overpayment" is unethical and dangerously close to dishonest. Additionally, Janet's failure to honor an offer that she herself made to make up for errors that she admitted occurred makes me seriously wonder about the core honesty of this this company and its leadership. Lowes has not only dropped them as a preferred contractor but will not even recommend them to its customers. Perhaps my experience with them was not that unique? read more
