I was dispatched to a home service call for a customer who was experiencing issues with their air conditioner. Upon arrival, I noticed that the system was cooling but there were multiple error codes indicating that the system was low on refrigerant. I performed a thorough inspection of the system and found that the float switch in the air handler was clogged with debris. I cleared the debris and re-installed the switch, but the issue persisted. I then inspected the air handler and found that the drain line was clogged with algae and debris. I used a drain cleaning tool to clear the line, but it was still not draining properly. I decided to remove the drain pan and clean the drain line thoroughly. After cleaning the line, the system was able to drain properly, and the error codes were cleared. The customer was very grateful for the service and paid the $1 service fee.
