Air conditioners are essential for maintaining a comfortable indoor environment whether that be in a home, office space, residential property or social space. However, like many electrical appliances, air conditioners can sometimes undergo issues which could impact the performance, output and possibly safety. Understanding the basics of troubleshooting these issues can help you identify and resolve them effectively and keep the system running as it should.

In this guide, we will explore some typical issues you may face with an air conditioning unit, simple steps to help and how Lee Jackson can help in regard to maintenance and repair work. We also have some other resources which cover things such as signs your air conditioning unit needs replacing and how often an air conditioning system requires a service.

Common air conditioning concerns

Blowing out warm/not cool enough air

The main reason people invest in air conditioning systems is to keep a moderate room temperature and create a comfortable environment in more extreme weather. But what happens when the air being released isn’t cool enough? The main causes of this could be a dirty or clogged filter, a blockage or low refrigerant levels which a technician would need to top up.

Leaking refrigerant

Your air conditioning’s refrigerant is the chemical used to cool the air processed by the unit, so if there’s a lack of refrigerant, this can affect many parts of the unit. If the refrigerant is at sufficient levels, the line will sweat and feel cold to the touch but if it doesn’t, this could be a sign of a more serious issue.

Strange noises

An air conditioning unit is made up of many different parts and electrical components so the odd sound is very common, however, if you’re hearing noises such as consistent squealing, rattling and humming, there could be an underlying issue with the motor or internal belt. If this issue arises, it’s important to contact a professional instead of looking at it yourself to prevent injury and any further damage.

Blocked vents

This particular issue can sometimes be a sign of poor installation or even poorly insulated walls. Unless you’re able to identify the issues visually and head-on, it’s best to talk to a professional about this as there could be a number of things contributing to the blockage.

Poor dehumidifying

Although the main responsibility of an air-con unit is to cool a space down, there is also the concept of dehumidifying which most modern systems are fitted with. This ensures that the environment doesn’t feel humid, stuffy or lock in access moisture.

Releasing bad smells

Any bad smell is unpleasant, especially if you have to live or work around it. If you have a bad odour coming from your air conditioning system, this could be a result of a dirty air filter, an obstructed drain line or a bad compressor. Although sufficient cleaning could do the job in the meantime, it’s important to get the unit professional looked at in case there is a more serious problem or you need to clean more restricted areas.
