Travis phoned promptly, first thing in the morning as I expected. He arranged a time to arrive, and was within the promised time period. Travis was professional, pleasant and respectful of our home and to me. He reviewed the house and then found a way to bring necessary supplies into the house with out leaving the front or back door open; a nice touch on a cooler winter day than has been the case of late! Something I appreciated were the little extras: demonstrating location and removal of furnace and humidifier filters, adjustment of thermostat settings so that temperature was shown in Centigrade, rather than Farenheit, and bringing incidental things to my awareness (eg: location of power switch for furnace). He even took an extra minute to correct the "ON/OFF" labelling of the power switch as it had been labelled incorrectly. Overall, I am pleased with the professionalism, service and respectful manner of the person representing Knight Plumbing, Heating and Air Conditioning. Many thanks!
