BEWARE!!! When we called Mike McPherson to come and look at our newly purchased Honeywell generator from Costco he asked for pictures, address etc. stating that "maybe I can figure this out before I get there" Little did we know he collected this information to turn us in to the County for a non permitted generator. All went wonderful with the County and we are now wanting the public to know how underhanded this man is. Shocking that a business owner would have such low standards. He actually could have come to us and said "hey! I can help you through this process" instead he took the low road. If you are concerned about anything on your property, DO NOT USE THIS COMPANY! Ah! How surprising that this "business owner" responded in such a defensive manner, just as he has done with all the other people who have had issues with him. Sooo, no, there was absolutely nothing wrong with the installation of our generator and passed inspection with flying colors. It was surprising to us that it even needed a permit but I will say that both the county inspector AND Honeywell were appalled to find out a businessman would have ever done that (Honeywell said unfortunately they do not have control of their repair persons but could not believe someone would stoop so low). They even suggested we should Yelp him Add my review to the numerous other negative reviews and hopefully that will be the WARNING ( as Mike put it) to honest and good intentioned folks that need to be aware of these type of scammers. read more

United Generator - Text from Mike McPherson so he could turn us in to the County! Even the inspector said that he should get yelped - Generator Installation/Repair Near Me - Santa Rosa, California

I'd be very careful using this company especially with Mike McPherson. His words to his customers tell the story-harsh, defensive, rude. I cannot prove it, (because they took everything with them at the time), but a company came recently to service my generator told me I needed a new battery. I told them it had just been replaced. They had me look at the notes inside the unit-which did not note the battery had been replaced, but should have if they did replace the battery. I now have had 2 pay for 2 batteries. The one they told me was bad (and took with them), but was not- and the new one just replaced AGAIN. Very dissatisfied. read more

THIS MAN IS SCARY! In December United sent a repair person to fix our generator. He took the ostensibly bad part and promised to return as soon as he could order a new part. Instead, the next day. the owner, Mike McPherson, texted me that they would not return to complete the work that they started and offered no explanation. He did not answer my first half dozen calls and texts and when he did, he still offered no explanation- and refused to return my part! (By the way, a subsequent repair person could seem to find no problem with the part) I had to threaten to call the police and report that he was refusing to return my property that he had taken before he did return it. I told him I would file a complaint with the BBB and post this review- You can see his utterly bizarre reply below. Turns out that i am not the only customer who has acted bizarrely toward: After a negative yelp review he threatened to have a bunch of his friends post negative reviews of the reviewer's own business. read more

United Generator - Generator Installation/Repair Near Me - Santa Rosa, California

EDIT: An hour after I posted this review Michael called me. I didn't answer. Screenshots of his VM message are attached. ‼ He threatened me if I didn't remove this review. ‼ I hadn't read the previous reviews before posting to warn myself of his history of harassment. My in-laws bought the property in 1971. My FIL, now widowed, has moved out of state. He has owned the property for 53 years!!! Since Michael didn't like the photo of my FIL check with an out-of-state address, I said I could use my check and I texted Michael a photo of my check. My husband and I live in Windsor. I NEVER said our situation was an emergency. No one is living in the house as it is For Sale. I simply wanted to secure an appointment for service. I was never told about who else needed service. By the way, shortly after Michael hung up on me, my husband drove up to the house with his tools. He removed the front panel, pushed a button, drove to Interstate Batteries to get a new battery and now the generator light is green and the house has power. All accomplished before dinner. NEXT DAY: Michael has had an unknown person post a bogus review on our business page. We don't even have a generator at our commercial building. The review has nothing to do with our business. Screenshot attached. Anyone know this person? ORIGINAL POST: I'm helping my elderly FIL who has a whole house generator that usually works perfectly, but this time when the power came on at the PG&E meter, it never came back on at the house. My FIL had United Generator LLC service the unit one year ago not long after my MIL passed away, so I called the number on the invoice and left a VM. I received a text after hours on a Friday, with a possible cause (PG&E power surge that burned the coils in the Automatic Transfer Switch) which was a similar explanation I received from someone else. I texted Michael every couple of days to inquire about getting on their busy schedule for the repair. The house has been without power for over a week now. Michael is condescending, forgetful and needs a lot of improvement with his big customer service skills. When I talked to Mike the first time on the phone, he corrected me and stated his name is Michael. He never mentioned that he works with his son, Mikey. He is forgetful because he asks the same questions over and over even though I have included most of the information in our text chain and we have talked several times about the location and situation. Mid-day today Michael responded to my text stating he might be able to come by around 2:00 this afternoon depending on how another job goes. While waiting for him to possibly arrive in an hour, he texted me the breakdown of the costs and asked for me to "bring a trust check with you?". I texted him a photo of the check. He stated he needed a check with my name on it because 'Lloyd is deceased." I re-explained that it was my MIL that passed away, not my FIL, plus I am on the account but not listed on the check. A while later Michael called me instead of texting to say that it looked like they would NOT be able to make it out today and could not give me a date/time of when they could schedule an appt. Unfortunately, the phone call ended with him hanging up on me. He wouldn't accept a verbal approval over the phone that I agreed to pay the minimum $500 that he explained would need to be collected at the time of service. He treated me like I lived down by the river when we have been business owners in Sonoma County since 1967. He wanted me to TEXT that I approved the fee; he said it was a "corporate policy". However, the invoice from 2023 states "We accept cc, wire transfers and ACH. Checks can be mailed to 1964 Respite Pl, Santa Rosa, CA 95403." I prefer ACH over writing a check and do most of my banking electronically but he didn't even offer that option. Maybe he just had a really off week? I never was given the opportunity to communicate with "Mikey". read more

See all

Mike Jr. did an incredibly efficient schedule B maintenance on my Generac 20k standby home generator. He was congenial & willing to answer any questions I had regarding maintenance & general information on my generator. I will recommend to anyone to call United Generator for any generator needs. read more

Something is wrong with Mike Sr. I have had communication that does not make sense. After trying to ask about qualifications to do some electrical work he wouldn't do the work at all. This could be interpreted as not being qualified. I feel sorry for Mike Jr. read more

Mik @ United Generator came out same day and solved my Generac issue. Very professional and courteous. I will be using them for my annual service for sure! read more

My generator needed trouble shooting as it shut down during a power outage. Mike and Mikey came out in a timely fashion to access and fix the problem. Thank you ! Customer service very important to me these days . Thank You ! read more

I have been changing the oil and cleaning my air filter on my generator for the past five years. Recently, after receiving an error message on my generator app aong with the error code, I contacted Mike Jr. who asked if I had ever had the valves adjusted per the manufacturer recommendation. As I only was doing the bare maintenance minimum, I scheduled a full service. The service rep came out in two business days and completed the service and had to replace the battery and corroded terminals. Mike Jr. and his company were prompt, reliable and stuck to their service quote, but had to add the battery and terminal costs that were found to be part of the starting issue. I am now on their schedule for annual service. I would highly recommend United Generator. read more

Very speedy help with cleaning and updating my generator. Great job in going over every item in this piece of equipment. Of course, I had not done any cleaning for a couple of years, so I will now, get it done from United Generator yearly . After all, the Generator helps me stay alive, when PG&E cuts us off. m hallin read more

Mike at UG installed a large generator for us several years ago. It has worked great. Mike is a good guy, very responsive, knows his business, and I trust him. I enjoy having his son, who is more and more involved in the business, come and do service. highly recommended. read more

Service was good. We appreciated them coming out as it is hard to find someone to service a generator in Sonoma county.

Installed replacement generator. Michael was great at communicating. Installation was timely and seamless. Highly recommend.

These guys are seriously the best. We recently bought a house which came with a previously installed whole house generator, something I have no experience with. We had United Generator come out for an annual service and they answered all my questions and provided great service overall. More recently, the power went out and the generator kicked on, but when the utility power was restored the generator shut off but the power in the house never came back on. I figured it had to be something with the transfer switch but don't know enough to diagnose it or attempt to fix it. Though my first call was to Mike at United Generator, I couldn't get a hold of them so I reached out to another company. When Mike got back to me, I described the situation over the phone and sent him a picture of the transfer switch. He was able to diagnose the problem from that one picture (one little wire had come loose), which enabled me to do the repair myself! I could then cancel the service appointment I had with the other company, saving me at least $250. Needless to say, as long as we own this generator we will be calling United Generator for any and all issues as well as regular service. read more

Wow, I wish I had read the Yelp reviews on United General before calling them to repair my brand new Generac generator that was installed by a local licensed electrical contractor. Generac sent me a list of their service contractors to choose from to repair the generator which did not turn over. UG came out and after 2 hours with 2 men (which only needs 1 tech to repair a generator) charged me $$$ for doing nothing. I had to call another company to come out and repair the generator which was done under warranty. The generator had a bad starter. I have asked UG for a refund and like the other bad reviews I have gotten nothing but harassing texts from UG at all times of the night. No referrals from this unhappy customer. read more

Was having generated issue at my pop-up. Mike came over and took care of my problem. I will highly recommend United generator to anyone looking for good quality product and great customer service read more

The Owner of this stand up shop Mike is amazingly patient and knowledgeable. He provided so much more information than the manufacturer of our generator. He doesn't even work on RVs and still he helped us trouble shoot fix and maintain our RV generator! Our RV shop wasn't able to provide this much support nor was the manufacturer of the ONAN Cummins diesel generator. Plus Mike had a soft spot for little dogs! This shop is knowledge, quality, professional and stands head and shoulders above all other shops we called Thank you Mike! read more

Michael was amazing! Totally solved my generator question/issue. He took time to explain everything, even sent me the manual for my 22kw generator for future needs, and walked me through everything step by step. He answered all of my questions. Very helpful. I also use them for annual maintenance. Highly recommend. read more

We had Mike Jr. out for annual maintenance on our Generac generator. He was prompt, thorough and spotted an issue that was done incorrectly on last year's maintenance by another company. He was exceptionally polite when he checked in with us after the service. We have already made a note to call United Generator next January for our annual service. Recommended them to our neighbor who was very pleased as well. Price seemed to be the going rate - fair enough. read more

United Generator has serviced our Honeywell Standby generator twice now, and their service is excellent. We've been getting an annual service, and Mike and his son Mikey have been amazing. Their pricing is fair, and I'm impressed with their knowledge and being conscientious about their work. Mikey cleaned the generator inside and out and answered all my questions. Highly recommend... read more

I contacted Mike at United Generator to schedule the initial servicing for my Generac generator. Mike called back the next day and got me scheduled on a day and time that worked for me. His son Mikey came out to do the service, arrived within the scheduled window and completed the work efficiently. Afterward I had some questions about the generator operation and future servicing, which he answered to my satisfaction. I highly recommend United Generator. read more

Contacted Mike at 9Am about our Generac needing service. We did not know the after 25hours of use it needed the break-in service. That was something that was not discussed with the company that originally installed it. He was here about 1030 and went over EVERYTHING he did and what to do in the future. Being a small biz owner I HIGHLY recommend United Generator for installation and service after install. read more

service was fast an Efficient. I would definitely use this company again

I called for maintenance on a Generac generator and got great, on time service....with a smile. I would highly recommend.

Good and efficient annual service. Work was done quickly and professionally. Scheduling was simple.

Mike McPherson, the owner of United Generator, and his son Mikey, are the most experienced, knowledgeable and dependable professionals in the North Bay generator industry. Before I purchased my Generac 22 KW Home Backup Generator I researched the various generator installers and service providers in the North Bay area and quickly discovered that United Generator was the best in the business and Mike was legendary for delivering service above and beyond the call of duty. He and Mikey keep my generator running in tip top condition and I highly recommend them to install and support your generator. read more

If you have a generator ~you NEED United Generator in Santa Rosa CA. I'm reminded how IMPORTANT it is to maintain one's generator on a day like this. PG&E outage . I'm home with no electricity today for a hot second 2-27-23 and then BAM!!! my generator kicked on and is running like a charm! Why am I yelping for JOY? Cause MIKE is the real deal. I'm a domestic engineer. It's my job to make sure my house runs efficiently. Without Mike's generator business I'd be sitting in a cold house with no water and no electricity. My family can't flush the toilets without our generator working cause my water pump needs electricity to pump the water to my home. I met Mike once when he serviced my generator in October 2022 . He made an impression on me. I will see him every year to maintain it. He's old-fashion goodness. He does what he says he's gonna do. He's reasonable and knows generators inside and out. He communicates well. All around awesomeness . ALSO, I've had some "other" local experiences with generator company's that were truly disappointing ..on many levels. I feel lucky that I found him. Days like this can be humbling without proper support. He's a cut above the rest. Thankful, Jen P. read more

I am not a typical customer and I really appreciate the tailorization that Mike provided. My needs ranged from basic PSPS home power to remote campsite power to occasional 3 phase needs of small commercial loads like wells or chillers. Also, I demanded an 1800 RPM machine for low sound levels and long service life. On the same subject, diesel too, for end-of-the world (common and easily-transported fuel) functionality. He immediately pointed me to a unit that met all needs yet was not overkill. In short, knowledgable and wise conversations led to a great purchase. read more

I wrote a long review of this guy Mike and his business practices the other day... After he read the review I got a whole list of threats from him by email, to take down my honest review of his incompleted work. I did tell him if he gave me my refund for work that was not completed, I would do so. This morning I got several harassing emails and more threats. I have turned this over to my attorney and will contact the Sheriff if I get anymore of these emails from him. Do not do business with this person, he is not working with a full deck ! P.S. He was paid $ 500 in cash on Dec 14th and the remainder $ 260. by check on Jan 10th. PAID IN FULL FYI. There is no "we" that came out to do the repair, it was only Mike and I have been pleasant to him the entire time until the first group of threats from him. In small claims court I will produce his receipt showing paid in full within 30 days. read more

So I had an issue with my RV generator. Being fairly new to RVs, I wasn't sure what to do when it stopped generating electricity. After calling several places, I finally called United Generator and the owner picked up. He said that his shop wasn't equipped to do RV related repairs, but what he did next surprised me. He started asking a series of questions, essentially guiding me through the troubleshooting process, and ultimately helping me reset the circuitry to get the generator producing electricity once again! This guy was very helpful, even giving me advice on the best care of my Oman generator. I would highly recommend United Generator for anyone looking for an honest guy to repair their generator. Thanks again for the help! read more

The work was completed on budget and on time. The generator comes on seamlessly when we lose power and has given us the confidence we need in these uncertain times! I also use them for my annual maintenance. read more

United generator installed my generator which was a great experience but the true test is when you have an issue. Today my generator went off line with an error message. I called Mike and he helped me to trouble shoot over the phone and got me back on line. With a heat wave pending I really appreciated Mikes taking the time to get be back on line-best of all no charge-thank you Mike read more

I called United Generator at 5 am to leave a message. Couldn't believe it... the guy answered. He realized right away that because we were 2 hours apart that I wouldn't likely end up a customer. He helped me anyway. This guy spent time on the phone figuring out my problem for me. If you are in his area I would highly recommend him. Great customer service!! Very knowledgeable! read more

They did an multiple year annual service on my Generic Generator. They did a good job including adjusting the valves.
