I have a aqualcal heat pump that has sprung a leak on the top of the heat exchanger. It's near one of the PVC pipes and I can visibly see a fine stream of water coming out.
Here's my question... Assuming my warranty is out on the unit, what are my options? Can just the top of the heat exchanger be replaced? How about repaired? Would an HVAC person be able to weld/solder a hairline crack? How about jbweld or some sort of epoxy?
I'm open to creative ideas!
