I broke down and turned on the AC for the first time today. I noticed just now that the air handler (lennox CBX32MV) is making a gurgling sound and that the drain pan is filling with water. The thermostat says that an HVAC error has been detected.
The system is 2.5 years old. The installer we used has recently had a serious health set back and I am not comfortable calling him for advice (it's a small, family owned company), so it looks as if I will have to find a new professional to fix the problem. I'd like to be "informed" while I am looking for a new hvac pro...does anyone have a suggestion as to what the problem might be?
