Learn the Major Air Conditioning Problems and How to Fix Them

It can be quite unbearable without proper air conditioning in Toowoomba. If your conditioner is down, you need to repair it. Keep in mind buying a new air conditioning system is costly, and repairing them can bite a huge chunk of your budget.

Stay on top of things by ensuring that your air conditioning systems are in pristine condition. For tech individuals, it is easy.  But you shouldn’t neglect your air conditioning system, anyway.

Here are essential things to watch out for:


A dry or clogged filter will considerably affect the functioning of your air conditioner. It is crucial to ensure that the filter remains in proper working condition.

Note that there are different types of filters from different manufacturers. Each one has a specific service time. While some are reusable, you can only use others once. Therefore, you might need to replace some monthly, after three months, etc. Check the manufacturer’s specification to determine the care practices for your specific filter.

Always clean your reusable filters when they attract lots of dirt. How do you know it’s time to clean an air conditioner filter? Check if light can pass through it. If the light doesn’t pass across it, then it’s time to clean the filter.

Accumulation of dirt typically causes freezing of the AC unit and reduces the flow of air.


A working compressor is responsible for the cooling of your house. This part is responsible for applying energy to the refrigerant and propelling it via the coils; thus, carrying out the heat exchange.

A faulty compressor means that the AC won’t cool your house. Again, if it has very little refrigerant, it runs hot and eventually stops working. Too much refrigerant, on the other hand, usually returns to the compressor causing its failure.


A thermostat regulates temperature stings within your home. Ensure that the thermostat is always on and on correct settings; otherwise, no temperature regulation occurs. Additionally, the thermostat shouldn’t be affected by sunlight. The inside must be clean and level.

Adhering to these factors ensures that it works exceptionally well. If the problem persists despite this, there might be another problem.

Evaporator Coils

These coils absorb the heat from the air and Chanel the air into the house as cold air.  It does so through a concatenation of ducts.

Sadly, the coils are prone to corrosion, mainly if located on the exterior. Coils located in the interior may not rust as fast. However, they’ll need maintenance every three years.

Refrigerant Leaks

Leakages in air conditioning systems are common, and they drastically affect their performance. Ideally, coolant leakages cause massive temperature fluctuations – poor performance.

Leakages can occur anywhere. Some are incredibly hard to repair; thus, more costly than those that are easy to repair. However, it’s advisable to have a professional AC technician check your systems.

Condenser Coils

Condenser coils, along with compressors, are located outside. That means they are prone to getting dirty as they can easily pick up elements. The impressive thing is that cleaning them is a breeze – just use a hose of water to clean them.

At times, they get too dirty. In this case, call a trained HVAC technician who will clean them using a chemical cleaner.


Drain lines naturally become clogged with dust, dirt, and link. And clogging causes filling up of drain pan resulting in leakages. In turn, this can damage the AC unit.
