How far one system home care today. Tested all electrical components on indoor system. I changed customers dirty filter. I also installed an Iwave today and tested functions. Customers drain line was clogged. I poured chemical and flush 2 gallons of water into the drain line and tested it twice. It is functioning well now. I also got great temp rise readings. System is heating and performing well at this time. There are no issues. Customer is happy.
