5 Incredibly Common Air Conditioner Problems & How to Fix Them

For most homes in Austin, AC and heating systems play an integral role in keeping homes comfortable. Since air conditioners develop many issues, we advise you engage technicians for a routine Austin AC maintenance service as a preventative measure.

According to the US Department of Energy, a central air conditioning unit has a lifespan of 15-20 years. So it means you’ll have to repair your air conditioner at some point before replacing it. We discuss the five most common AC problems and the solutions;

Low Refrigerant

Your air conditioner might be low on refrigerant if it doesn’t cool properly. The unit may have been undercharged during the installation or has a leakage. If the refrigerant is leaking, get a qualified technician to repair it before testing and recharging.

Electric Control Failure

When the air conditioner repeatedly turns on and off due to, say system oversize, then the compressor and fan control might wear out. You’ll also note the corrosion of wires and terminals. In the light of this, be sure to get a professional to check the electrical connections and contacts.

Thermostat Glitches

Another common AC problem is a faulty or improperly functioning thermostat. If it happens that your thermostat is improperly calibrated, then it’ll not signal the air conditioner to start or turn on.

Call an HVAC repair technician if the thermostat is set to the lowest temperature, but the unit will still not turn on. A professional will recalibrate or replace the thermostat if it’s faulty.

Leaking or Dirty Ducts

It’s a sign of improper airflow through the ducts if some parts of your house are cool while others are warm. Even if the ductwork runs through the ceilings and walls, tears might develop due to rodents and poor artistry.

The ducts are the mediums for airflow, and if they’re ripped, then it’s possible the air is escaping inside the walls or wherever the ducts run. When the air escapes, your house will get warmer and warmer, and the bills will start increasing. So, be sure to call a professional technician to inspect the air ducts.

Compressor Failure

The compressor is a critical component in an air conditioner that applies energy to the refrigerant and then propels it through the coils to carry out the heat exchange.

If your AC unit compressor stops working on a hot day, then you shouldn’t expect your AC to cool the house. The odds are high the high-pressure limit switch may have tripped. And to reset it, push the button positioned at the compressor’s access panel.

In Conclusion

AC units experience many issues, which is why they require frequent maintenance to prevent these problems. For reliable & affordable Austin AC maintenance, installation and repair services, Contact Christianson Air Conditioning & Plumbing.
