Thanks for taking my question. Every time my HVAC unit comes on (right now, it's the AC part that's coming on), it kinda bangs. First it fires up then moments later, it bangs. I guess that's when the blower comes on.
I'd like to know if anyone has any insight as to what's going on. Also, is this an indication that the unit may be going bad? The unit is at least 6 years old. 1994 if when we bought the house.
