2 months ago this would have been a 5 star review…. My generator started having issues in June, service was able to get it working over the phone in just a few minutes. Great! Early July had a power outage on Sunday, generator turned on, no power in house. Called for emergency service 2x. No return call. Followed up on Monday, nothing, called again Tuesday finally scheduled a regular appointment for 2 weeks out. They they pushed back appointment to last Friday. Friday comes and no one shows up. I call and am told the tech called out sick and someone would reach out to reschedule. Nope. I call again am given a new date in Mid August with the promise of a call back shortly. Nope. Nearly a month has gone by with no action for what was requested as emergency service. 8/3/25 Update- Despite a very positive response from Gen Star to my review, nothing changed- No return call from service manager as promised. No less than 5 phone calls requesting a conversation with a manager went unanswered. I was able to find another vendor that was able to address my issues within a day of my request. Genstar was unable to assist on an issue that arose on 7/4, until 8/10. Completely unacceptabe. Since no one will return a call, please accept this note as my official request to cancel my service contract.
Exceedingly poor customer service from Genstar. I have a 2 year service contract for servicing of my whole house generator. I was charged $345.00 for this year's service last month, the date the contract was signed 2 years ago even though actual service was scheduled a month later. A month ago on 23 June i got this text message from the company; "Hi Joseph, Leo Lopez from Genstar Service LLC is scheduled to arrive Tue, Jul 28 between 8:00am-10:00am." Yesterday i received this text message; "Hi Joseph, Leo Lopez from Genstar Service LLC is scheduled to arrive Tue, Jul 28 between 9:00am-10:00am." This morning no one showed up as per the messages and there was no calls or text message to indicate status of today's service. At 10:30 am I sent this message; "Hi. What is the expected time of arrival for Leo for the scheduled maintenance? Thx. Joseph Mathews" Additionally I made 3 calls to the company all of which were answered by the answering service. Finally I got this text message from the company at 12:51 pm; "Hi Joseph, Tristan Bowen from Genstar Service LLC is scheduled to arrive Tue, Aug 4 between 9:00am-10:00am." No calls from the company asking me if the reschedule date and time were acceptable or to inform me about the reason for this morning's planned service not happening and for the reschedule to next week. I am deaf and use implants to hear and couldn't do anything as I miss door bell rings and knocks, phone calls and so waited all morning for the technician to arrive or response from the company. This is extremely poor and unacceptable customer service.
Genstar gave us the best estimate for replacing our stand by generator. The team they sent out to do the installation were very professional and they did the job in record time. I feel very confident in being a Genstar customer.
Genstar has been nothing but amazing from day one. We purchased a Generac 24kw whole house generator and it has worked seamlessly, particularly because of Genstar's excellent customer service. We bought a maintenance plan with them and it has been well worth the money! Highly recommended.
Don't do business with this company. You'll save yourself a lot of frustration. I bought a 26Kw generator and I regret doing it. Has broken 3 times in the last few months. They don't return calls, hard to set up a repair appointment. Just a mess. I am going to write a letter to generac corporate headquarters and see what that does. I also regret buying the 7 year warranty. My previous generator from Total Comfort was much better
