“We had an excellent experience with EcoTemp HVAC last Monday. Our boiler was malfunctioning, and they responded the same day we called. Jordan, our technician, went above and beyond by stopping on his way home to make sure we weren’t left without heat. He was extremely knowledgeable about Navien boilers, quickly identified the issue, and fixed it efficiently. Professional, courteous, and clearly well versed in his work. We truly appreciate the exceptional service and wouldn't hesitate to recommend them to anyone needing boiler service— especially Navien systems.“
