I called The HVAC Service when our water heater started making a strange whining noise. Our technician, Benjamin, was extremely pleasant and seemed very knowledgeable. He checked the unit and said that it was caused by the build-up of scales on electrical heating elements. He flushed the water heater, cleaned the scales, and installed low-watt-density heating elements with a larger surface area. We would highly recommend this company.
