If you have an “Emergency Heat/EM HEAT” option on your Thermostat, the next few days it would be a good idea to run emergency heat until temps get back above freezing.
Your system will attempt to keep up in these conditions in regular heat mode (via your outdoor condenser) but will continually go into a defrost mode that is not the most effective or efficient way to heat your home in sub 32 degree weather conditions. By going into “Em. Heat” you are bypassing the outdoor all together
and saving yourself some potential headaches.
