Air moves, but electric heat is missing

Name the heat source before the part

Bring an existing equipment invoice or a label visible from normal standing space. The cabinet label and a separate heater label may describe different parts. Use only labels already in view. Leave a hidden label for the person checking the unit.

Tell us if the thermostat shows Aux or Emergency Heat, but do not use that label as proof of the installed hardware. Supplemental heating arrangements differ. Setup changes require knowledge of the actual system.

Report what still works

Does air move? Do any rooms warm? Say whether the problem appears in normal Heat mode or only with a backup-heat message. Describe what you already saw; do not force a heating stage to test it.

A fan can move air while the heat source is unavailable. Conversely, a missing fan response can make a heating complaint an airflow or power investigation. Do not order heating elements solely because the air feels cool.

Separate the heating section from the whole system

Ask which part was tested and why it did not work. A heating-section repair needs parts that fit the model. Ask about any related wiring or safety-control fault. Request an explanation of whether the blower and controls can remain.

A heat-pump compressor or refrigerant repair is a separate job. So are a new circuit, a panel change or a whole new indoor unit. Ask which work is accepted and who will do it before approving extras.

Make the approval specific

Ask for the diagnostic charge, planned work and any excluded access or electrical work. If equipment is behind a locked door or above a finished ceiling, explain that before agreeing to a visit.

A larger heater is not a default cure for poor heat. Ask what supports the recommendation and whether the existing equipment, airflow and electrical supply are suitable. Product selection and electrical testing need an onsite check.
