Our heating suddenly went out and we needed it repaired quickly because we have an elderly mother living with us. Our usual company would not come out because it was past nine p.m. We contacted Elm and they arrived promptly. The technician, Vince M., was absolutely outstanding. He quickly diagnosed the problem, explained what had to be done, and repaired the unit. He was courteous, informative, and professional. We were also satisfied with the reasonable price. We are definitely switching to Elm for our heating and cooling needs.
