    I have a trane system
    Air Handler TWE065 / XLI9i / Honeywell T8624D Thermostat

    When in heating mode, the outside unit's fan always comes in the higher speed, regardless whether it is using one or two compressors. Works fine in cooling

    Any suggestions

    When it runs in heat mode it's trying to absorb heat from the atmosphere and the pressure in the coil is much lower. Did it used to change speeds or has it always done this? Could be it's supposed to always run on high in heat.
