No Superheat, But Perfect Subcooling?! Dirty Coil or Bad TXV? Real HVAC Service Call w/ Mikey Pipes

When central AC cooling problems strike, Mikey Pipes answers the call — even on a Sunday. In this uncut, raw service call in Merrick, Long Island, Mikey dives into a residential system that has no superheat but perfect subcooling. What's to blame? A dirty outdoor coil? A bad TXV? Or something deeper inside the system?
