My air handler’s input temperature is 51 degrees and the output temp is around 59. But the air coming out of the vent is 68. My filters are clean. Any ideas on what might cause this? Thanks!
I was a bit confused by your posted numbers at first without knowing what kind of system you have. I have researched some of your past postings and I'm making the following assumptions. -Chilled water cooling airhandler with geo w2w HP 51f=Chilled water coil entering water temp 59f=Chilled water coil leaving water temp 68f=Supply air temp at room outlet Can you confirm this is correct? If yes we need to know (at least for now) -Room temp -Entering air temp at airhandler -Leaving ait temp at airhandler -Is your airhandler and/or duct work in an unconditioned space like a hot attic? -Are there any other possible heat sources (hot water coil, dehumidifier etc) in the system? Answers may lead to a diagnosis or more questions.
