Why Is My Air Conditioner No Longer Cooling?
Why Is My Air Conditioner No Longer Cooling?
It is hot, your air conditioner or heat pump is running, but the air stays lukewarm. Sound familiar? Several reasons can explain why your air conditioner is no longer cooling. Here are the signs to watch for and the solutions available to you.

1. Dirty or clogged air filters
Over time, the filters in your air conditioning system collect dust, pollen and other particles. When they become dirty or clogged, the airflow is reduced, which keeps your unit from working properly. The result is air that is less cool, or even downright warm.
What should you do?
Remove the filters and inspect them. For wall-mounted heat pumps and air conditioners, we recommend cleaning the washable filter once a month. For central heat pumps, the filter should be replaced every 3 to 6 months.
2. Electrical problem or faulty component
If the outdoor unit of your air conditioner or heat pump does not start, it may be an electrical problem or a failing part (control board, capacitor, etc.). In that case, the air conditioner stops cooling altogether, even if the unit seems to be running.
What should you do?
This type of breakdown is not something to diagnose yourself. Contact a professional for a complete inspection.
3. Refrigerant leak
Refrigerant is essential to produce cold air. If refrigerant levels are too low, your system loses efficiency and blows warm air.
What should you do?
A refrigerant leak must be located and repaired by a certified technician. Simply adding more refrigerant is not a lasting solution.
4. Problem with the outdoor unit
The outdoor unit of your air conditioner or heat pump must release heat for the system to produce cool air indoors. If it is blocked by debris or the fan is faulty, overall performance suffers.
What should you do?
Make sure the unit is free of any obstruction. If the problem persists, a component may need to be replaced.
When should you call air conditioning professionals?
When your air conditioner can no longer produce cool air and the problem seems to persist or to involve internal components, it is best to leave the diagnosis to an expert.
