During the hot summer months, the last thing anyone wants is their air conditioning system to stop cooling. It can be frustrating and uncomfortable when this happens, but it’s not uncommon. There are several reasons why an air conditioning system may stop cooling, and most can be fixed with a little troubleshooting. In this article, we will explore some common causes of air conditioning not cooling and what you can do to fix it.
Check The Thermostat
When your air conditioning system is not cooling, the first step is to check the thermostat. Ensure it is set to the correct temperature and “cool” mode. Sometimes, the thermostat may not work correctly, leading to the air conditioning system not cooling. If you suspect that the thermostat is faulty, consider replacing it or calling a professional to do it for you.
Inspect The Air Filter
A dirty air filter is another common cause of an air conditioning system not cooling. When the air filter is dirty or clogged, it restricts the airflow, making it difficult for the air conditioning system to cool the room. Check the air filter and clean or replace it if necessary. Ideally, air filters should be cleaned or replaced every 30-60 days, depending on the usage.
Check The Air Ducts
The air ducts are responsible for carrying cool air from the air conditioning system to the rooms in your home. If the air ducts are dirty or blocked, it can cause the air conditioning system not to cool correctly. Check the air ducts and ensure that they are clean and unobstructed. You can also consider hiring a professional to clean the air ducts.
Check The Refrigerant Levels
Refrigerant is a chemical responsible for cooling the air in your air conditioning system. If the refrigerant levels are low, it can cause the air conditioning system not to cool effectively. Check the refrigerant levels and ensure that they are at the correct level. If the levels are low, you may need to add more refrigerant or call a professional to do it for you.
Check The Outdoor Unit
The outdoor unit of your air conditioning system is responsible for removing heat from the indoor air and releasing it outside. If the outdoor unit is dirty or blocked, it can cause the air conditioning system not to cool correctly. Check the outdoor unit and ensure that it is clean and unobstructed. You can also consider hiring a professional to clean the outdoor unit.
Check The Condenser Coils
The condenser coils release the heat the refrigerant absorbs from the indoor air. If the condenser coils are dirty and clogged, it can cause the air conditioning system not to cool effectively. Check the condenser coils and clean them if necessary. You can use a soft brush or a vacuum cleaner to clean the condenser coils.
Call A Professional
If you have tried all the troubleshooting steps above and your air conditioning system is still not cooling, it’s time to call a professional. A professional HVAC technician has the expertise and tools to diagnose and fix complex air conditioning problems. They can also perform routine maintenance on your air conditioning system, ensuring it runs efficiently and effectively for years.
