"Anthony arrived on time and went straight to work. He worked steadily and when completed explained that the heater is in good shape with nothing wrong. He did not have the intake filter with him so he offered to come back and install it, this was not part of the original deal. He showed up this morning and installed the filter, cleaned the vent and cover. Excellent customer service.
