And I found slant aluminum evaporator coil in air handler has a “dead spot“ where water is dripping off. I checked Freon level. OK. Superheat: 10. Sub cooling: three. Return air: 75. Supply air: 55. Six or seven dry passes. I called carrier distributor for tech-support And left a message. They did not call back. I covered dead spot with tape for temporary repair. And I also sprayed coil fins with EAC cleaner.
