Summer is here, and a working air conditioner is your solace for comfort. But what happens when your AC suddenly stops cooling? At Residential Heating and Air Conditioning, we understand how frustrating this can be, and we’re here to help with AC repair in Minneapolis. Here’s a look at why these breakdowns occur and how we tackle them.
When does it make sense to call a professional if your AC suddenly stops cooling?
Call a professional HVAC technician if your air conditioner suddenly stops cooling and you notice any of the following:
- The thermostat settings are correct but the unit still won’t cool (possible thermostat malfunction).
- The unit has a refrigerant leak or low refrigerant level (system can’t cool effectively).
- Evaporator coils are frozen (often due to poor airflow), blocking cooling.
- Electrical failures — for example a tripped breaker or faulty wiring causing the unit to shut off.
Common Causes of Sudden AC Failures
Several issues could cause your air conditioner to stop working unexpectedly:
- Thermostat Issues: Sometimes, the problem is as simple as incorrect thermostat settings or dead batteries. Other times, the sensor might malfunction, telling your AC to shut off prematurely.
- Refrigerant Leaks: Your AC needs refrigerant to cool the air. If there’s a leak, your system won’t cool effectively. In many cases, refrigerant problems are linked to larger performance issues like what short cycling means for ACs, which can strain your system and lead to further damage.
- Frozen Evaporator Coils: If your AC doesn’t get enough air, the coils can freeze. When this happens, the ice blocks the air, and your unit stops cooling.
- Electrical Failures: Electrical issues such as tripped breakers or faulty wiring can also cause your AC to shut down suddenly.
