I have a Trane heat pump, installed when the house was built in 1995. I also have a nice gas furnace. I am currently using the furnace for heat and use the Heat Pump for A/C only.
I'm concerned about the pressure equalizing noise coming from my reversing valve when the A/C shuts down. It seems to be getting louder, too. I'd hate for it to fail in the deenergized state; I'd lose A/C, and I don't even use it for heat! Besides the noise is annoying!
I'd like to simply put the valve in cool mode and not worry about it any more. I could do this by putting 24v on the solenoid and taking it off of control by the thermostat. Even if the solenoid fails from running full time, I'd rather take that and buy a replacement solenoid instead of suffering a valve failure...
Can the solenoid stand to be under power 24/7?
