Great service, efficient, friendly but some confusion about the charge

I believe we were told that there would be a $79 charge that would be applied to the hourly rate for coming out in general and then another $95 charge as a result of it being a Sunday… I’m not sure how our charges ended up being $230 but the technician was wonderful and we are very appreciative for his visit and the excellent work that he did.

Great Service

Other than the fact that we had to reschedule the service 3 times waiting for parts, when the service was completed, it was great. The technician was very knowledgeable and very efficient. He explained every step he took as well as the billing. We are very satisfied with this service call.

Awesome Service

I was able to schedule an appointment on the day and during the time period I wanted and needed. The Electrician, Rick, arrived within the time period provided. Rick was very friendly and replaced my bathroom light fixture very quickly. It looks great!
