Air conditioner cut-off?

My MH has a single standard air conditioner. Does anyone know of an add on you can get to have it cut off at temp? My compressor cuts off but the fan still stays on. I wouldn't mind except it's right over the sleeping area and is quite noisy.

    When your A/C is running, the compressor causes the coils to get cold on one side, possibly causing a build up of frost, and heat on the other side. The fan not only circulates the air but defrosts the cold coils and cools the hot side. The fan needs to run all the time to avoid problems.

    You could try turning the fan speed down, but keep in mind that you may then have problems with the coils freezing up, especially in humid weather.

    Do the fans on ducted air conditioners run all the time as well? I thought they shut off like a home unit. Also, can standard non-ducted air conditioners be set up to run off of a wall thermostat?


    The fan stays on even for the units that are ducted. It does not function like home.
