The answer to 'why is my central air' is that there could be several common causes for your central air conditioning system not working properly. Some of the most common issues include a clogged air filter, a refrigerant leak, a problem with the compressor, or a thermostat malfunction.
If your air conditioner is not cooling your home effectively, the first thing to check is the air filter. A dirty or clogged filter can restrict airflow and cause the system to work harder, leading to decreased efficiency and potential damage. Replacing the air filter is a simple DIY task that you can do yourself.
