Telltale signs your Air Conditioner needs cleaning

07 Jul 2020

Regularly cleaning and sanitising your air conditioner is important for overall efficiency and function. Plus, it will help remove the dust and dirt, mould and mildew that builds up deep within the machine, spreading germs and allergens through your environment. There are a few tell-tale signs your air conditioner needs a clean as soon as possible.

The external vents are covered in mould and mildew

If you can see mould on the external vents, when the air conditioner is on, it’s definitely time for a thorough clean and sanitise. By the time this microbial contamination can be visibly seen on the external vent, the inside of the machine is most likely riddled with mould and its harmful spores.

The aircon filter is covered in dust and dirt build-up

This build-up of microbial contamination prevents your air conditioner from running at its optimum level. A dirty filter is often the first obvious sign an air conditioner needs cleaning, and it should be cleaned every 3 months if used regularly. It is possible to DIY when it comes to the filter, however you should always exercise caution when cleaning components of electrical devices. A dirty filter spreads that dust throughout the air, which can be troublesome for those suffering from allergies.

The aircon is blowing hot air when it should be cold

Many people rely on their air conditioners to provide year-long comfort for their home or office, so when it just doesn’t do as good a job at cooling the room as you’re used to, it’s frustrating. The first step to fixing this problem is a thorough clean as the air conditioner is likely struggling to operate efficiently. On occasion, it may be a refrigerant leak, but this tends to be a relatively uncommon problem.

The aircon is ‘huffing’, ‘wheezing’ or rattling

Any unusual noise coming from your air conditioner should always be investigated. These noises tend to get worse if the problem isn’t resolved. A fan, bolt or panel may be loose, or the fan may have become unbalanced due to dust collecting on it. The coil fins may also need a clean out. Getting to the bottom of this problem ASAP is important.

There’s a pungent smell coming from the air conditioner

Air conditioners have a drain pan that can get clogged up, resulting in mould and mildew growing and releasing their familiar musty smell. Sometimes, this water, and dark space becomes tempting for small animals, such as lizards, which then get stuck and decompose, adding to the smelly situation. This is a definite time for a HydroKleen.

It’s been over 12 months since your aircon was last cleaned.

You may not notice any of the previous signs that should trigger a clean and sanitise, but let us assure you, if it’s been over 12 months since a clean, your air conditioner will be harbouring, dust, dirt and microbial contamination. Recirculating these allergens through the air can make all of us feel sniffly and sick, not to mention the additional electricity costs of running an inefficient air conditioner!

Benefits of Inverter Air Conditioning

Inverter air conditioning is more expensive than non-inverter air conditioning, but with the deteriorating state of the energy system in South Africa, it is a worthy investment to consider.  The main difference is that an inverter air conditioning unit delivers a fixed amount of power using a fixed speed compressor. The speed of the compressor varies, so as to deliver the precise cooling or heating power required.

Benefits of inverter air conditioning

  • Up to 40% cheaper to run as it consumes less power
  • Reaches the desired temperature quicker
  • Startup time is reduced by 30%
  • Much quieter when running
  • No temperature fluctuations, therefor maximizing comfort level
  • No voltage peaks from the compressor
  • All Samsung inverter air conditioners are heat pumps which in itself is one of the most energy efficient form of heating.

How does inverter air conditioning work?

The amount of cooling or heating required by an air conditioner varies depending on the outdoor temperature and the amount of heat in the room. When cooling or heating capacity needs to be decreased, the compressor will operate at a high speed and will increase the amount of refrigerant flow.

When the inverter air conditioner is switched on, the compressor operates at a high speed in order to cool or heat the room quicker.
