Boiler replacement complete. New Bosch Condensing Boiler installed.

Recent Carrier heat exchanger replacement.

Recent service call on a walk in freezer. Last company working on it replaced the defrost timer. Unfortunately they wired it wrong along with not installing the drain pan properly causing water to pool and produce steam in defrost mode. Didnt help that the defrost was wired wrong and running way longer then necessary wasting energy and putting excess heat into the freezer. A couple hours with my multi meter and a drill and this system is now running like new.
