Air conditioning units are a modern comfort that we rely on, especially during summer. Like every other appliance in our home, these units require regular care and attention to function effectively. If you want to keep your air conditioning running smoothly, be on the lookout for these warning signs.

Unusual Noises

Air conditioners are designed to work quietly and efficiently. If you hear noises that are out of the ordinary, it could be an indication of underlying problems. The types of sounds can vary, each hinting at different issues:


  • Buzzing: It could be due to debris in either the indoor or outdoor units, loose parts or issues with the compressor or fan.
  • Clanging or banging: These sounds often indicate a loose or broken part within the system.
  • Squealing: This might be an indication of problems with the fan or its motor.

Inadequate Cooling And Poor Airflow

The purpose of an air conditioner is to provide a comfortable and cool environment. If your unit is failing to fulfil its primary function, it’s a sure sign of a problem.



  • Your air conditioner might be blowing warm air instead of cool, pointing towards a failing compressor or a refrigerant leak.
  • If your unit isn’t able to cool your space effectively, this could be due to a blockage in the ductwork, a clogged filter or an ageing motor.
  • A unit that takes unusually long to cool the room might be a sign of a low refrigerant level or a problem with the thermostat settings.

Persistent Unpleasant Odours

A ducted air conditioning system operates on a simple yet efficient mechanism. The central unit begins the process by drawing in air from the surrounding environment. This air is then passed over a series of cooling or heating coils, depending on your desired temperature, effectively conditioning the air.



The conditioned air then travels through an interconnected network of insulated ducts, ultimately reaching each room or zone connected to the system. In each zone, the air is circulated through strategically placed vents, which could be in the ceiling, walls or floor, ensuring an even distribution of temperature.

Increased Humidity

Air conditioning units serve more purposes than just cooling your space; they also help control humidity levels. If the atmosphere of your home still feels humid even with the air conditioner running, your unit might be in trouble.



  • An air conditioner that fails to control humidity could have an issue with its dehumidification process.
  • It could also mean the unit needs recalibration, or there might be a larger issue.

Short Cycling

Regardless of the weather, your air conditioner should have standard cooling cycles. If you notice frequent cycling, it might be time to get your unit checked.



  • Short cycling can be due to improper sizing—the unit may be too large or small for the space it’s cooling.
  • Other reasons could be a blocked filter, low refrigerant or a faulty thermostat.
