About
Understanding the problem
A heat pump can have a mode-specific fault, an airflow problem, or a control issue affecting both heating and cooling. Outdoor frost during heating must be interpreted with the normal defrost cycle in mind.
What our service assessment covers
We assess mode changes, thermostat configuration, airflow, outdoor-unit operation, defrost controls, and relevant refrigeration and electrical components. Diagnosis follows the equipment’s actual sequence.
Before you schedule
Tell us which mode is affected, the outdoor conditions, and whether auxiliary heat appears on the thermostat. Photograph any persistent ice without trying to remove it mechanically.
