Why Do Air Conditioners Fail In The Summer? [Lafayette Edition]

Summers in Lafayette are not for the faint of heart. With average summer temperatures pushing into the 90s, residents expect their AC systems to be reliable. So why is your AC blowing hot air all of a sudden? Or has stopped turning on altogether?

Follow this guide from Tim’s Southern Air to learn why air conditioners seem to always fail in the summer, understand what causes an AC unit to fail and how you can avoid one this summer. Relax in the knowledge that you’re prepared for whatever the summer season throws at you!

The Most Common Reasons ACs Fail

Frozen AC

As backward as it sounds, summertime is when your AC is at the highest risk of freezing. After a long winter, your AC unit may not be up to the challenge of sudden searing temperatures. If your unit is dirty, worn out or has broken parts, ice can form on your evaporator coils and freeze your unit. Frozen ACs are commonly caused by:

  • Poor airflow
  • Dirty evaporator coils
  • Refrigerant leak
  • Faulty wiring

The good news is that the warm temperatures outside will help defrost the unit with ease! You can also contact a professional and let us handle the AC repair!

Poor Airflow

Your HVAC system is made up of multiple fans and ducts that move air around. Over time, dust and debris can build up in the system and block airflow. This can cause your unit to work harder and put it at risk of breaking. Remember, your system needs a clean filter to function efficiently.

Dirty Evaporator Coils

In a similar way to having dirty fans and ducts, the coils in your AC unit can become dirty. Grime can build up on the coils from debris in the air, interrupting airflow and making your unit less efficient. Debris can even enter your system and cause clogs, resulting in a broken or frozen AC.

Refrigerant Leak

If your AC is blowing hot air or you hear a hissing noise, your unit may be leaking refrigerant. Without refrigerant flowing through the system, hot air cannot leave your home. If your AC takes a long time to cool your home, you may have a refrigerant leak. Call a professional to handle refrigerant — it’s extremely dangerous!

Faulty or Loose Wiring

An air conditioner contains lots of electrical components. With regular use, one or more of these parts can wear out or become loose. Over time, your system will stop running efficiently and may break down completely. Never try to fix an electrical component yourself – always contact a professional for repairs.

Unresponsive Thermostat Sensor

If you’ve exhausted the common AC repairs and your unit is still not working, the problem may be indoors. If your thermostat sensor isn’t working properly, your AC unit will not turn on. Contact a professional to test your thermostat sensor and consider upgrading to a smart thermostat.
