If your air conditioning unit is not producing cold air or seems to be less efficient than usual, it may be a sign that it needs a regas. Regassing, also known as recharging or refilling, refers to the process of adding or replenishing refrigerant to the air conditioning system. Here are some common signs that your AC unit may need a regas:
Warm air blowing from vents: If your AC is blowing warm or lukewarm air instead of cold air, it could be an indication that the refrigerant levels are low.
Reduced cooling performance: You may notice that your air conditioner is not cooling your home as effectively as it used to, even though the settings and thermostat are correct. This reduced cooling performance could be due to insufficient refrigerant.
Increased running time: The AC unit may run longer than usual or cycle on and off frequently in an attempt to maintain the desired temperature. Low refrigerant levels can cause the system to work harder to achieve cooling.
Ice buildup on the evaporator coil: A thin layer of frost or ice on the evaporator coil, which is located inside the indoor unit, may indicate a refrigerant issue. If you notice ice buildup, turn off the AC and call a professional to inspect and address the problem.
Hissing or bubbling noises: Unusual sounds coming from the AC unit, such as hissing or bubbling, could be a sign of refrigerant leaks. Leaks lead to a loss of refrigerant, which can affect the cooling performance.
Visible leaks: Sometimes, you may spot oil or refrigerant leaks around the AC unit or the refrigerant lines. These leaks need to be addressed promptly to restore proper functionality.
Higher energy bills: If your energy bills have increased significantly without any change in usage patterns, it could be because your AC unit is working harder to compensate for low refrigerant levels.
If you notice any of these signs, it's essential to have a qualified HVAC technician inspect your air conditioning system. Attempting to regas the AC unit yourself can be dangerous and may void any warranties you have. A professional will diagnose the issue, repair any leaks if necessary, and recharge the system with the correct amount of refrigerant to ensure efficient cooling performance.
