This is a Mismatched heat pump with high pressure issue in heating mode and the fix is a heat pump mild weather switch.
mild weather switch also known as a low ambient switch.
Cool 😎 Mr . Dallas isn’t that also know was a fan cycling switch ?
Mix matched coil and poor duct work sounds like a standard system out here👍😂😂
Hi Dizzie, First of all I wanna say I'm a fan and like watching your tubes. I've installed fan cyclings on heat pumps for the cooling mode on units that were located in windy areas or on roof . those units were running low head in cooling due to location . but it's the first time I hear of a fan cycler for head pressure in heating mode . It's a fantastic bandaid for your issue and hope you get to shoot a video replacing that hack job 👍Keep em coming.
Nice, where do you hook your gauge up on the vapor line, don’t you have the pressure switch threaded on the shraeder valve. I know they have T’s. Thanks.
Where do you splice the switch wires? Common wire going to fan?
