What this usually means
Check whether the home temperature is rising even if the air feels only warm. Heat pumps often deliver heat gradually.
If the home loses temperature, auxiliary heat never engages when needed, or the outdoor unit develops abnormal ice, professional diagnosis is appropriate.
What you can safely check
- Thermostat is in HEAT mode
- Indoor temperature trend
- Filter condition
- Whether the outdoor unit is operating
When to call a professional
Call when the home cannot maintain temperature, the system runs continuously without progress or abnormal icing persists.
