Today we came out due to main floor system not heating. System would to try to ignite but would not go past that stage. This was due to carbon build up on flame sensor and a loose connection on wire for gas valve. I cleaned the flame sensor and secured wire connection. System fired up. We let it run for about 45 minutes and it is operating as it should. I noticed the blower wheel has dirt and debris build up on fan blades. There are 5 start collars not properly sealed allowing leakage of air flow where there shouldn’t be. There is no flood protection on drain line. After going over all findings options and customer is signing up for the Home Care Plan today. Once the home care is scheduled, I will return to do maintenance on both systems. It was a pleasure to meet you today and I hope you have a great weekend!
