Had a 20 year old unit quit and expected to be told it was time to buy a new one. We were tired of dealing with the 'big' companies so when a friend told us about Bumblebee we decided to give them a try. So glad we did. They came out on a Saturday, looked at the unit and told us it was in good shape except for a burned out fan motor. At one tenth the cost it was replaced, the unit serviced and it now works like a charm. The crew was great and even schooled me on the inner workings of the unit. I did some checking and their price was more than competitive. Though there's no guarantee on the older parts not failing, it was worth the chance it will give us a few more years. We highly recommend them.
