Oliver did a fantastic job, and I was very satisfied with them.
We love Oliver, and we use them for a lot of different jobs.
They were on time. They called when they were coming, and then they were very knowledgeable of the situation. They identified why we didn't have electricity in part of the house. We've used them for many years. They're an A+ company.
They're friendly and courteous, and they get the work done on time. They do my routine maintenance. I've been using them for about two years now, and they've earned an A+ grade.
They did electrical work. They conditioned the generator to make sure it worked. There were no problems, and I did not have to call them back. I would recommend them, and I'd give them an A.
My husband was here when they came; he said they were nice, and they took care of the problem. I'd give them an A.
Oliver was very good. We were very satisfied with their services.
Everything is good.
I always have a positive experience with Oliver. They're always very efficient and very professional.
I liked that they came out promptly and got the job done. I think the last thing we had them do was take a look at our dryer, and they determined that we needed a new part. They came out and installed it. I'd give them an A.
