Man repairing AC

When your air conditioner stops working out of the blue, it can make life uncomfortable and unpleasant. Air conditioning is a necessity, especially in hot climates. Due to the potential cost of repairs, it’s crucial to perform regular maintenance to keep the air conditioner in good shape. Purair Air Conditioning and Heating offers exceptional AC repair in Navasota. It’s a good idea to be knowledgeable about some of the more common problems that can affect your air conditioner.

Clogged filter

One of the most common reasons for air conditioner failure is a clogged or dirty filter. Following the manufacturer’s recommendations, change the air filter. Some come in handy three times annually, while others are used only once a month. Still, others are washable and reusable. One way to tell if a filter needs cleaning is to observe how the light passes through it. In addition to reducing airflow, filthy filters can also freeze the air conditioner.

AC making noises

Depending on the nature of the issues, an air conditioner can emit a variety of noises. Your air conditioner may be making several different noises for many reasons, such as:

  • A refrigerant leak can generate a hissing sound.
  • Your AC’s relay may be malfunctioning if you hear clicking noises when you turn it on and off.
  • An issue with a blower or motor assembly is indicated by thumps, rattling, or banging noises.
  • You might hear screaming noises when there’s an underlying issue with the fan or compressor motor.
  • Malfunctioning electrical components generate a buzzing sound.


The compressor provides energy to the refrigerant and drives it through the coils to perform heat exchange. If the compressor fails, the air conditioner won’t be able to cool your house. Insufficient refrigerant will cause the compressor to overheat and eventually stop working. The compressor will collapse if there are too many because the refrigerant will leak back into it.

Drainage issue

It is possible for dirt, algae, and dust to clog the drain pipeline. Mildew, fungus, and mold growth can increase if the fluid does not drain thoroughly. Additionally, gases and unpleasant odors may enter your home.

Sensor malfunction

A thermostat sensor is present in the air conditioner, situated close to the evaporator coil. The thermostat gauges the temperature of the air in the evaporating coil. It also modifies the cooling according to the room’s conditions. However, if the sensor is out of its position, the air conditioner may randomly turn on and off or cycle continuously. The sensor and evaporator coil shouldn’t be close to one another. Are you looking for AC repair in Navasota?
