Heat pump

Stephen Hales | Posted in Energy Efficiency and Durability on

Why does my heat pump just started to go into defrost mode when it is only 60 degrees outside temp?

    Is it possible to supply any LESS information about your heat pump? ;-)

    Different makes & models use different approaches for controlling defrost modes.

    Sorry bout that it's a Revolv and it is about 4 yrs old never gave a problem before. Think 4.5 ton unit everything is clean coils inside an out

    Stephen,
    The problem you describe can't be solved over the internet. You need to call up a service technician.

    Is it possible it is low on refrigerant causing lower pressures and possibly freezing? I know A-coils will freeze over if this is the case on regular A/C units. I would think it could work in reverse and freeze the condenser in heating mode.
