Yes, those are classic signs of a refrigerant leak, a common issue in our area. We use electronic leak detectors and ultraviolet dye to pinpoint the exact location. Once found, we repair the leak, perform a system evacuation to remove moisture and air, and then recharge it with the precise amount of refrigerant specified by the manufacturer. This restores efficiency and cooling power while preventing further damage to the compressor.

That's coil corrosion, often caused by our humid climate and exposure to lawn chemicals or salty air. It reduces efficiency and can lead to leaks. We thoroughly clean the coils to remove debris and corrosion, then apply a protective coil coating. This non-acidic treatment shields the aluminum fins from further corrosion, extends the unit's life, and helps maintain its energy efficiency.

Regular maintenance is key. We recommend twice-yearly tune-ups. In spring, we'll clean the outdoor coil, check refrigerant levels, and look for early signs of corrosion. In fall, we focus on the heating system. This proactive care catches small issues like minor leaks or corrosion spots before they become major, costly repairs, ensuring your system runs smoothly through Georgia's hot summers and mild winters.
