What Is The Most Common Problem With HVAC Systems


HVAC systems have become an integral part of Australian households and business establishments to enhance the comfort and well-being of the users. However, even the best HVAC systems are prone to technical faults and breakdowns. This can be extremely frustrating and discomforting for the users, especially since repairing these complex electronic devices is both expensive and difficult. Being aware of the various problems that can disrupt the normal functioning of HVAC systems enables users to take the necessary precautions and prevent their complete breakdown. Given below are the brief details of some common problems with these systems that you need to keep an eye out for. 

Dirty And Blocked Filters & Coils 

One of the most common problems in HVAC systems is that of dirty and clogged filters and coils. This reduces the performance efficiency of the HVAC system by blocking free air flow and also results in increased energy consumption.  Many times, you may also experience loud and irritating noises being emitted by the system due to clogged filters and coils. Cleaning the HVAC system thoroughly and following a regular maintenance schedule can help resolve the problem. It is equally important to clean the filters frequently and replace them from time to time. 

Breakdown Caused by Blown Fuse 

One of the most common problems with HAVC system that people face is a breakdown caused by a blown fuse. The fuse may get blown due to various reasons, including current overload, water leakage, and even a dirty air filter. You should check both the power source and the fuse regularly for excessive heating and frequent tripping.  It is also important to get the blown fuse repaired at the earliest as otherwise, it might cause the problem to escalate and make the repair work more complex and expensive.   

Burnt Out Printed Circuit Board (PCB) 

If the HVAC system is not turning off or its various settings and features are not working properly, it might be indicative of problems in its printed circuit board (PCB). A burnt-out PCB can cause the system to malfunction and can lead to other performance issues if left unattended for a long time. It is best to hire the services of a professional technician for checking and repairing the PCB to resolve the problem efficiently. Trying to repair the PCB on your own without proper knowledge or tools can not only complicate the problem but also cause an electrical shock. 

Refrigerant and Gas Leakage 

Any leakage of refrigerants or gas within the HVAC system can prevent it from functioning normally besides having dangerous consequences. In addition to reducing the efficiency and life of the system, it can result in creating serious health problems for you and your loved ones. The leaks may be caused due to corrosion of pipes, or the development of mechanical faults in the system. Many times, an improper or loose connection may also result in such leaks. Irrespective of the cause, it is important to seek immediate professional help to resolve the problem and avoid putting the health of your loved ones at risk. 

Faulty Or Damaged Compressor 

If the HVAC system is not producing enough warm or cold air irrespective of the right settings, it might be indicative of problems with the compressor. The compressor is the heart of the HVAC system and is responsible for regulating the temperature of the air flowing through the system. So if the compressor is faulty or damaged, it is not able to heat or cool the air as per the desired temperature settings. Since the compressor is a highly sophisticated component of the HVAC system, it is advisable to avoid trying to repair it on your own. Rather you should get in touch with an expert professional without delay to prevent the problem from escalating further and impacting the performance of the other components of the system. 

Water Leakage

Water leakage is yet another most common problem with HAVC system faced by people for which they might need to seek professional advice. In most cases, the water leakage is caused due to the broken drain pan resulting in the water leaking through the various cracks and holes in the system. It is highly advisable to avoid repairing the leakage on your own as it might result in an electrical shock. Rather you should contact an expert technician with the right tools and equipment to stop the water leakage. It is also recommended to switch off the HVAC system until the leakage is repaired as otherwise, it might cause further damage and also lead to short-circuiting the system.  

Final Thoughts 

HVAC systems play an important role in enhancing the comfort of our homes and workspaces, especially during extreme weather conditions. However, it is important to maintain them properly to optimize their performance and enhance their life. By paying attention to the smallest details and remaining alert about any changes in its functioning, you can avoid spending a huge amount on repairing or even replacing the system.
