I have been in business for 10 years and I will never go anywhere else for my generator. Extremely knowledgeable, quick, reliable, experienced, and just really good at what they do! They have saved the day more than once;) Thank you so much AZ Generator!! read more

First time using Az Generator and couldn't be happier with the service or the turn around time to get my generator running. Price was fair

Awesome great service you can trust. From one tech to another these guys are the best

Communication was excellent. They came to our home and diagnosed the problem immediately and repaired my rv generator on the spot. They had the necessary parts on hand. They were very up front and I was able to pay on the job site and my receipt was texted to me. Charles Chapmen and his assistant were very courteous and respectful read more

Appears to be out of business. Reviews here are very old and after a week of calling and texts I don't get a response. A shame. as Chuck was good at servicing generators. read more

Chuck is the absolute best. He has been my go to onan generator repair guy for a few years now. He's helped us with all sorts of fault codes, carburetor problems, control board problems, fuel pump problems, Flywheel Cuppling replacement, belt replacemets, pully wheel replacement & all sorts of other stuff. After our old Onan 7000 watt generator started having cylinder problems (expensive to fix) we opted to buy a new Onan 7HGJAE-2132 which we were able to buy it directly through Chuck & he came & swapped out our old one for us. Chuck is a wealth of knowledge & explains everything he needs to fix (in terms that are understandable.) He is an all around nice guy & although it always sucked to have my generator breakdown it has always been an enjoyable experience getting to visit & chat about all sorts of stuff with Chuck. I recently purchased another brand of generator & the way our electricians wired it to our breaker was all screwed up somehow. 2 electricians couldn't figure out how to balance the loads on our 2 legs & their solution was that my 7600 (running) watt generator wasn't enough power I got in contact with Chuck & he was able to get me squared away in about 30 minutes, he truly is a generator wizard. Thanks again Chuck, my family & I always appreciate your hard/precise work. read more

I am so glad I found Chuck, with AZ Generator. He is honest, has integrity and knows hi stuff!

Chick is Awesome! Is super helpful and goes out of his way to resolve your generator issues, even during off hours. I highly recommend him for your generator needs. read more

DON'T CALL ANYONE ELSE FOR YOUR GENERATOR SERVICE OR REPAIR!! Chuck was courteous and punctual and diagnosed my problem quickly and professionally. Service cost WAS VERY REASONABLE!! You know how there are times you can just see how a person goes about their work that they really know what they are doing--well that's how I felt watching Chuck doing his work!! You will not regret using AZ Generator!!!! read more

Chuck the owner scheduled a service call within 24 hours of my contacting the company and came to me in Cave Creek, with his assistant, Rick. Very nice people. When he checked my RV generator he determined the likely cause of the breakdown and referred me to another service company who specialized in older Onan generators like mine and would have access to parts he didn't have. Turns out, I had used the person he referred me to, 10 years ago. Chuck doesn't charge a service call fee if you're within his large service area and $125/hour labor. More than fair these days. He did not charge for his service call and was happy to provide the contact info for the other service company. Would highly recommend for their integrity and prompt response to my service request. read more

Just had my generator serviced. Chuck did a great job. Showed up on time had everything that was needed and was done within an hour. His price is was extremely fair. I would highly recommend him. read more

The generator whisperer. Chuck loves generators as much as I love AC in the Arizona heat. I'm almost speechless. Chuck did a job in three hours (in the dark) that the big boys quoted me 12 hours. $2600 or $600 including parts. Do not waste your time paying for nice buildings with a bunch of salaries walking around. Chuck fixed my generator faster and for less $ than the other guys charged me to tell me what I already knew and how much more money to put in a single part. And it runs like new! read more

Chuck stopped by my house this evening to fix my RV generator. He is sincerely passionate about the work he does. He is not just in the generator business. He is in the helping people business. He quickly diagnosed the problem and gave me a fair price to fix it. Along with the fix Chuck gave me lots of advice to keep it running smoothly and avoid future problems. RV generator is running smooth now. Thank you sincerely AZ generator. read more

Wow, I'm stunned, there is actually an honest, fair business person in the state of Arizona. Called Chuck to look at my RV generator which wouldn't start and was spitting fuel when I tried to get it going. Even though he was obviously sick and sounded horrible, he came out the next day, arrived when he said he would, analyzed the problem, gave me a factual, truthful explanation of the issue, quoted me a no BS price, gave me a couple of other options based on his experience. Will absolutely use him again and recommend him to all friends and relatives. Thanks Chuck. read more

I couldn't get my generator to start in my food truck. They came to my house and fixed it on the same day. Awesome service couldn't be happier. I highly recommend them! read more

Chuck responded quickly, came the next morning, and was able to fix the generator quickly. He is very nice, knowledgeable and professional. He knew exactly what to look for, and I will definitely call him again. Thanks, Chuck for such great service. read more

Very rarely do I post regarding a company or service provider as I figure I'm paying for that companies product or that service and I should be getting what I'm paying for more or less. Every once in awhile though, someone goes the extra mile or spends extra time to provide me with exceptional service or goes beyond the scope of their duty to make me happy. CHARLES and AZ Generator deserves a good positive review and much more. About 8 months ago I bought a new RV in Arizona. I live in Southern California and purchased out of state because of greed and nonsense the dealers put you thru in my home state. Shortly after purchasing the RV I began to have problems with my Onan 5500 Generator and made the long tow from Calif to Arizona for warranty repair. Charles was the tech that repaired my gen. He ended up fixing multiple issues, one of which was an assembly problem from the factory causing the gen to not get fuel because of a kinked fuel line. He thought the problem was fixed and I took the coach back to California. A short time later I began having a different issue with the gen and took it back to Charles to deal with. He diagnosed the problem and changed the carburetor. I took the coach home and on my next camping trip, ran into the same generator problem but with a different trouble code. I notified Charles and he walked me thru different adjustments and was extremely patient. He answered a ton of my dumb questions and never made me feel that I was bothering him. When he determined that the new carburetor he just installed probably had a bad float, he offered to come to me. He's 3.5 hours away and was more concerned about fixing my problem and making me happy than the distance or personal cost to him. You just don't get that kind of service these days. At least I don't. Charles is a very nice person and truly cares about his customers. Anyone else would have told me to bring the coach back or find someone closer to my area to obtain warranty repairs. But I trusted him and only wanted one hand in the pot. Nobody else would have cared but he recognized that I had already spent quite a lot of money getting the RV to him for warranty repair and was willing to help me out by making the trip himself. I just want to personally thank Charles and AZ Generator for their attention to detail. This is a guy that knows his business and is willing to educate you and help you maintain your equipment where others want you in and out as fast as possible so they can move onto the next job. Thank you Charles. Appreciate your help sir read more

Could not recommend a service company more. Chuck let us know before hand the cost of both labor and parts that would be needed to fix are generator. Not only did he fix the generator in record speed he took time to educate me on what happened, why it happened and how to prevent it in the future. He did all of this out in a 110 degree temps and was one of the nicest people I have dealt with in a long time. Do yourself a favor and contact Az Generator first, it will be well worth the effort. And the best part is, they come to you. Thanks again Chuck. read more

I gave Chuck a call after being referred by a friend. Chuck discussed my situation and gave me.some things to try before he would come out. After the suggestions did not resolve the problem he came out and had it running within an hour. In the future I will always go to AZ Generator for service on my Onan diesel generator. Thanks Chuck!!! read more
