It is quite easy for homeowners to take their air-conditioning system for granted—at least up until the temperature in your home becomes unbearably hot or cold, depending on the ambient weather. This is when homeowners rush to seek air-conditioning maintenance and repair to ensure they do not have to go through the summer or winter with a malfunctioning unit. However, air-conditioning problems do not crop up overnight. You need to learn how to spot the signs during the early stages of your system failing so that the underlying problem is remedied before it becomes aggravated. Below is a compilation of some of the signs that would indicate your system needs air-conditioning repairs.

Your air-conditioning system is making strange noises

There are several reasons why strange noises would be coming from your air-conditioning system. One of the more common culprits for this is a fan belt that has come loose from the unit. This can easily be fixed by a technician, as it simply involves securing it back into place.

Another cause of noise from your air-conditioning unit is if the compressor has started being exposed to tremendous pressure when in operation. This is much more serious, as the compressor is one of the essential components when it comes to the functioning of your unit. It would be prudent to cease using the air-conditioning system until a technician has fixed or replaced the failing compressor.

Your air-conditioning system is emitting foul smells

If you begin to smells whiffs of burning when you turn on your air-conditioning system, this should be a cause for alarm. Burning odours from your air-conditioning unit will almost always indicate an electrical problem with the system. This electrical problem could be caused either by a component that is overheating or an actual electrical fire happening within the system. It is crucial to stop using the air-conditioning unit completely until the electrical problem has been identified and rectified by a technician.

Another smell to be wary of is a musty odour is in the air-conditioned air. In this case, it could indicate that you have moisture collecting in the unit and creating a breeding ground for mould and mildew. Left unchecked, your air-conditioning unit could become a health hazard to your home, as it will be circulating the mould spores around your home. If this were to happen, your unit would require immediate, thorough cleaning by a professional technician.
