I had a problem with a hot water heater. It had quit heating water so I called AHS for service. They sent out [Another plumber]. The man from [Another Plumber] was here for about 15 minutes and said he didn't find anything wrong. Took the check for services. Two weeks later there was a blast of fire from the water heater and it quit working again. AHS sent out Ronnie Miller from Stark Services. He did a wonderful job and was very knowledgeable about what he was doing. I will use Mr Miller for any problem I have in the future.
