Water heater went out over the weekend. Unit was 50 gallon and 11 years old. Called sterling and talked to technician and received a quote that sounded reasonable. I received a call from main office to schedule an appointment and they could be there in the afternoon. Tried to turn water off to water heater and found out both my shutoffs were bad. Called technician back and ask if he could fix those too. He said he could. Very pleased with the customer service they provide and work that they did. Highly recommend. My technician name was mike. He was there till 8 pm.
