When I set my thermostat to heat, the heat turns on and the air temp is hot from the registers but after about 15minutes of operation I notice the air temp from the register starts to cool to room temp more or less. also there is a noise coming from the outdoor unit that sounds like pressure venting. this seems to coincide with the cooling of the air in heat mode
Sounds to me like the outdoor unit is malfunctioning. Could be a control board going crazy, could be the reversing valve leaking. A trouble call to the local contractor is the best idea, preferably a firm that deals with your brand.
