Perform two system home care today check the furnace and all of its entirety. Cleaned flame sensor changed the filter that the customer supplied the furnace has no wet switch. I quoted it. The drain line was clogged. I got the mighty pump and pumped all the water out. Went back with another 2 gallons of water and poured endure afterwards. The mini split is working properly at this time. I tested it in heat and changed its filter also. Customer wanted me to change the humidifier pad so I also changed it and collected payment. Both systems are performing well for heating season at this time.
