Common causes

A heat pump may run for long periods during very cold weather or when it needs to maintain a steady temperature. However, if it appears to run continuously, possible causes can also include an incorrect thermostat setting, dirty filters, restricted airflow, reduced system efficiency, thermostat problems or a system fault that requires inspection.

What to check

Confirm that the thermostat is set to the correct mode and that the selected temperature is reasonable. Check whether the filters are dirty and make sure airflow openings are not blocked. Also observe whether the system reaches the selected temperature or continues running without reaching it.

When to request service

Consider requesting a professional inspection if the heat pump runs continuously without reaching the selected temperature, if electricity use increases unusually, if airflow is weak, if excessive ice appears, if the system produces unusual noises or if it continues running after the thermostat has already reached the selected temperature.

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.

During very cold conditions, a heat pump may normally run for extended periods. What matters is whether it reaches the selected temperature and maintains stable operation.

What can I check if my heat pump won't stop running?

Confirm that the thermostat is set to the correct mode and a reasonable temperature. Check that the filters are clean and that airflow openings are not blocked. Also observe whether the system reaches the selected temperature.

When should I request service if my heat pump runs continuously?

Request a professional inspection if the heat pump runs continuously without reaching the selected temperature, electricity use increases unusually, airflow is weak, excessive ice appears, the system produces unusual noises or it continues running after reaching the selected temperature.
