During warm months in El Paso, Texas, people rely on their air conditioner to stay comfortable. However, your AC system can’t perform well if it’s low on refrigerant. Here are a few signs to look and listen for that can tell you that your AC system is low on refrigerant:
Warm Indoor Temperature
If your house still feels warm when your AC system is on, it might have low refrigerant. You may not see any issues with the system, but the air won’t cool as much. If your thermostat shows that the temperature is more than four degrees above what you set it to and there’s no obvious reason, you may be low on refrigerant. The refrigerant helps cool the air passing over the coils in your air handler. The less coolant you have, the less effective your HVAC system is at cooling the air in your house. As a result, you’ll feel uncomfortable in a hot and stuffy home.
Ice Buildup on Outdoor AC Unit
Another clear sign your AC system is low on refrigerant is that there’s ice buildup on the outdoor unit. Refrigerant must maintain a stable pressure. When the pressure is stable at the right pressure level, the refrigerant is more effective at moving heat out of your house. When there’s a refrigerant leak, the pressure and temperature drop. When it gets too low, the temperature can drop below freezing and cause the condensation on your coils to freeze over. If you see ice anywhere in your system, it may be time to call a specialist to conduct an assessment.
Audible Hissing Noise
Hissing noises are sounds you don’t want to hear from your AC unit. Being low on refrigerant means that there’s a leak somewhere. Systems tend to lose refrigerant over time at a very slow rate. A hissing sound means that refrigerant is escaping the system at a high speed, and you need to find the leak soon before it runs out completely. Therefore, you need to schedule an AC repair right away.
