5 of the Most Common Air Conditioning System Problems and their Fixes

During the hot and dry months, air conditioners are undoubtedly deemed a must-have, if not a total necessity.

After all, it has been designed and created to minimise, if not totally eradicate the discomforts that come with the scorching heat of the summer season.

However, just like most modern innovations, air conditioners sometimes fail to perform as expected. With that in mind, the need to do regular maintenance checks is more important than ever.

Below are some of the most common air conditioning problems that you will likely encounter and some of the easy ways to fix them.

Problem #1:  Unusual noise

Oftentimes, deafening noises coming from air conditioning units can be attributed to one main reason – a misplaced fan belt. While unknown to many, air conditioning fan belts have the tendency to get dislodged from time to time.

Solution: Fortunately, restoring the fan belt in its proper place can easily solve the problem. While you are at it, it would be advisable that you check the motor bearings as well. In some cases however, lubrication or replacement is the most appropriate solution to address this issue.

Problem #2: Undesirable Smell

Air conditioners undergo a continuous process of warming and cooling. Taking that fact into account, it’s safe to assume quick moisture build up is almost always inevitable. In addition, the presence of moisture will likely encourage the growth of moulds, fungi and other microorganisms that can eventually cause bad odour.

Solution: Ensure filters are changed regularly to hinder the presence of moulds and fungi so you can keep foul odour at bay.  

Problem #3:  Sensor Issues

At the back portion of the unit’s control panel is where you can find the thermostat sensor. Its main purpose is to measure the temperature of air entering the evaporative coil. When the sensor gets displaced, the unit will likely function erratically or in some cases, cycle continuously.

Solution: To prevent any likely sensor issues from occurring, it will be best to routinely check if the sensor is positioned appropriately.  

Problem #4: Abrupt Breakdown

In some instances, the unit might not turn on, or in worst case scenarios, might stop working altogether.

Solution: In cases like this, it will be best to check the fuse and circuit breakers. In addition, ensure the thermostat is adjusted to cool and should be below room temperature. Furthermore, make sure the condenser and furnace power switches are turned on.

Problem #5: Leaking Refrigerant

A faulty refrigerant can be caused by two reasons. Either it was undercharged during the installation process or it can be due to an air conditioner leak.

Solution: In a scenario like this, merely adding a refrigerant will not do the trick. That being said, it is highly advisable that you seek the help of a professional technician to help you address the problem properly. A competent one will be able to repair the leak, test the repair and recharge the unit with the suitable amount of refrigerant. Air conditioners normally perform at its best when they contain the exact same amount of refrigerant the manufacturer specified. Also, bear in mind that undercharging or overcharging can affect its efficiency over time.

Regardless of the type of air conditioner you are using, routine upkeep should be in place if you want your unit to work efficiently. In other words, whether you have a ducted air conditioning unit or a tower ac, periodic maintenance should be observed so you can look forward to many years of efficient and hassle-free usage.
