The answer to 'why is my AC' is that there could be several common causes, such as a refrigerant leak, a clogged air filter, or a problem with the compressor or electrical components. Symptoms may include the AC not cooling properly, strange noises, or the unit not turning on at all.
Some issues, like a clogged air filter, can be easily fixed with DIY maintenance. However, more complex problems like refrigerant leaks or compressor failures usually require a professional HVAC technician to diagnose and repair. It's important to address AC issues promptly to prevent further damage and ensure your home stays comfortable.
