AC repair typically involves addressing specific issues with the system, such as refrigerant leaks, faulty components, or electrical problems. This can be a more targeted and efficient solution than a full system replacement, which can be significantly more expensive. Additionally, AC repair can often be completed more quickly than a full system replacement, allowing you to get your cooling system back up and running faster.
