Common causes

A heat pump may stop producing enough heat for several reasons. Possible causes include an incorrect thermostat setting, dirty filters, restricted airflow, excessive ice buildup on the outdoor unit, problems during the defrost cycle or a fault that requires technical inspection.

When to request service

Make sure the system is set to heating mode, check the temperature setting and confirm that the filters are clean. If the heat pump still does not produce enough warm air, develops excessive ice, shuts off repeatedly, displays an error code or produces unusual noises or odors, consider requesting a professional inspection.

How much can this repair cost?

Basic air conditioning repairs or initial work typically range from $650–$1,200 MXN. Repairs requiring parts or more extensive work can range from $1,200–$5,500+ MXN.

The final cost depends on the cause of the problem, diagnosis, labor, required parts and materials. Replacement parts are quoted separately when applicable.
