5 Signs Your AC Unit Is Low on Freon and Needs Attention

Living in Arizona makes it essential to have a fully working air conditioning unit. With summer temperatures often exceeding 100°F, you need your AC to work efficiently. One of the most common issues with air conditioners is low refrigerant, also called Freon.

5 Signs Your AC Is Low on Freon

1. Warm Air Blowing from Vents

The first thing you'll notice if your AC is low on Freon is that it blows warm or mildly cool air instead of cold air. Freon is what cools the air in your system. Without enough of it, the air won't get properly cooled.

2. Longer Cooling Times

If it's taking much longer for your home to reach the desired temperature, your AC may be low on Freon. The AC struggles because there isn't enough refrigerant to cool the air efficiently. Running the AC for longer periods without addressing the issue can lead to more wear and tear.

3. Higher Energy Bills

When the AC unit is low on refrigerant, it works harder to cool your home, using more energy, which leads to higher electricity costs. Given that air conditioning already makes up a big portion of energy use in Arizona homes, this can really hurt your wallet.

4. Frozen Evaporator Coil

If you see ice or frost on the evaporator coil, it's likely a sign that the unit is low on Freon. Without enough refrigerant, the coil gets too cold and freezes, decreasing the efficiency of your AC and potentially leading to more serious issues.

5. Hissing or Bubbling Sounds

Freon leaks are one of the most common reasons for low refrigerant levels. If you hear hissing or bubbling noises coming from your AC unit, it could mean that Freon is escaping through a leak. Running your AC without enough Freon can damage the compressor, which is a costly component to replace.

Why Should You Act Quickly?

If you notice any of the signs mentioned above, it's important to call a professional AC repair service. Running an air conditioner with low Freon for too long can cause more damage, leading to expensive repairs or even the need for a new unit. A professional HVAC technician can inspect your AC system, identify any leaks, and top up the Freon if necessary.
