  • "John followed up to a previous visit. He promised to service and flush our water heater. For this follow up visit this past Monday 6/15/20, he arrived on time and quickly went to work. He not only flushed the water heater but also replaced the elements that were in bad shape. John was professional and extremely responsive and did an excellent job! " Read More
