What customers say about our service call
Called the service pretty late last night and was able to get a service call for today. The experience was awesome. My technician arrived early (!) and was honest and helpful in guiding us to a decision as to the best course of action for our a/c unit. He spent time to explain the technicalities instead of just walking around and providing a bill. I know that that it is said that you have to "earn" someone's business, but with service, knowledge and experienced technicians, I am just grateful to have found what I now KNOW.
