The answer to 'why is my AC repair' is that there are several common causes for air conditioning issues, including refrigerant leaks, compressor failure, electrical problems, and clogged or dirty components. Symptoms may include the AC not turning on, poor cooling, high energy bills, or strange noises.
Many AC problems can be fixed with DIY troubleshooting and minor repairs, like replacing air filters or cleaning the condenser unit. However, more complex issues like refrigerant leaks or compressor failures usually require a professional HVAC technician to diagnose and repair properly. Attempting these repairs yourself can be dangerous and may void the warranty.
