I have a 7 year old carrier central airconditioner.
In march, 2012 all Freon tubing and copper lines were replaced. In dec. 2012
A motor module was replaced. Since these events, we hear a "mini" explosion
In the air handler once a day and only during air conditioning season.
Could there be a bubble in the Freon lines?
Any help would be appreciated. My service company is stymied.
