If you’re having trouble getting your air conditioner to cool your home, you’re not alone. Many homeowners experience this problem from time to time, which can be quite frustrating. Fortunately, you can take a few simple steps to identify the source of the problem and get your air conditioner cooling again.
How an Air Conditioner Works
First, it’s important to understand how an air conditioner works. An AC unit cools your home by removing heat from the air inside and transferring it to the outside. This is done by refrigeration, in which a refrigerant is used to absorb heat from the air and then released outside. The air inside is then cooled as the heat is removed.
The Common Problems When AC is Not Cooling
- Thermostat The thermostat is the brain of the system, so if it’s not set correctly, the AC won’t work properly. Check to ensure the thermostat is set at the desired temperature and the fan is set to “on.”
- Dirty Air Filters If the air filter is dirty, it can block the airflow and prevent the AC from cooling the home. Check the filter and replace it if needed.
- Refrigerant Leaks Refrigerant is essential to the cooling process, so if it’s leaking, the AC won’t be able to cool the air. Have a professional check the system for leaks and repair them if needed.
- Condenser Unit The condenser unit is responsible for releasing heat from the air. If it’s dirty or not functioning properly, it won’t be able to do its job. Have a professional inspect and clean the condenser unit if needed.
- Evaporator Coil The evaporator coil is responsible for absorbing heat from the air. If it’s dirty, it won’t be able to do its job. Have a professional inspect and clean the evaporator coil if needed.
- Bad Contactor The contactor is the switch that turns the power on and off to the compressor. If it’s bad, the compressor won’t be able to turn on and off, leading to a lack of cooling. Have a professional inspect and replace the contactor if needed.
Prevention is Cure
Preventative maintenance is key to avoiding costly repairs and running your air conditioner smoothly. Have a professional check your system at least once a year and replace air filters every few months. This will help keep your system running efficiently and avoid any significant issues.
When To Hire a Professional Service
If you’re having difficulty with your air conditioner, it’s best to contact a professional service. A technician can diagnose the issue and provide the necessary repairs. It’s important to have the issue addressed as soon as possible to avoid further damage and costly repairs.
The Bottomline
A variety of issues can cause air conditioners not cooling. It is important to identify the exact cause of the issue to find the most appropriate solution. Common causes of an air conditioner not cooling include low refrigerant levels, blocked air filters, and faulty or worn-out components. It is best to consult a professional HVAC technician to diagnose and repair the issue, as they have the necessary tools and knowledge to do so.
