Air conditioning systems are essential for comfort in both homes and businesses. Whether it’s a hot summer day or a humid evening, air conditioners keep indoor spaces cool and comfortable. However, just like any other appliance, air conditioning units can face issues from time to time.
Knowing the most common problems can help you identify when your system needs repair and save you time and money. Here are 8 common aircon repair issues that affect both residential and commercial properties. Find out more as you continue reading.
1. Air Conditioner Not Turning On
One of the most frustrating problems with an air conditioner is when it refuses to turn on. This issue can happen for various reasons. It could be a problem with the power supply, like a blown fuse or tripped circuit breaker. Another common cause is a faulty thermostat, which may not be sending the right signal to the unit.
In commercial properties, air conditioners may be tied into complex electrical systems that need more careful attention. If your aircon doesn’t turn on, it’s a good idea to check the power and thermostat settings before calling a professional for help. If your air conditioner is not cooling properly, it may be due to dirty condenser coils, which can hinder the system’s ability to release heat effectively.
2. Poor Airflow
Another frequent issue that air conditioners face is poor airflow. If your aircon is blowing air but it doesn’t feel cold, there could be an issue with the air filters, ducts, or fans. Clogged air filters are the most common cause of reduced airflow.
In addition to making the system work harder and obstructing airflow, dirty filters can also damage the unit and increase energy usage. Dirt and debris can build up in business areas’ air ducts, further decreasing airflow and efficiency. Maintaining the system’s smooth operation requires routine filter cleaning or replacement.
3. Refrigerant Leaks
Refrigerant is essential for the cooling process in air conditioners. When your aircon starts refrigerant leaks, it will not cool properly. A drop in refrigerant levels can cause the system to overheat, leading to potential damage to the compressor.
A refrigerant leak can be caused by a variety of issues, including corrosion, damaged coils, or loose connections. This issue can be more common in older units, but it can happen to any system. Professional repair is necessary to fix the leak and refill the refrigerant to the correct level.
4. Frozen Evaporator Coils
An air conditioning system’s evaporator coils are in charge of drawing heat from the atmosphere. The system will have trouble efficiently cooling the area if these coils freeze. Low refrigerant levels, filthy air filters, or a lack of ventilation are frequently the causes of frozen coils.
When the coils freeze, the aircon will be unable to cool the space, and it can cause additional damage to the system. This issue is relatively common in both residential and commercial properties, and it’s important to have the coils thawed and the underlying cause addressed by a technician.
5. Strange Noises
Air conditioners should run quietly, but if you start hearing strange noises such as rattling, buzzing, or grinding, it’s a sign that something isn’t right. In many cases, these noises can indicate loose parts, debris in the unit, or problems with the motor.
In commercial properties with larger or older systems, the issue could also be a sign of mechanical failure, such as worn-out bearings in the fan or compressor. If you notice unusual sounds coming from your air conditioning unit, it’s best to call a professional to inspect the system before further damage occurs.
6. Water Leaks
Air conditioners produce condensation, which is usually drained away from the unit through a drainage pipe. However, if this drainage system becomes clogged or damaged, water can build up and cause leaks. Water leakage can also occur if the evaporator coils freeze and melt, causing water to accumulate around the unit.
This is a common issue in both residential and commercial systems, especially in older units. If you notice water pooling around your air conditioner, it’s important to address the issue quickly to prevent water damage to your property.
7. Faulty Thermostat
A malfunctioning thermostat is another common issue that can affect the performance of your air conditioner. The thermostat controls the temperature and signals the system when to turn on and off. If you’re experiencing issues with your unit, scheduling an air conditioning service can help identify and fix the problem before it gets worse.
In commercial properties, where large and complex air conditioning systems are often used, faulty thermostats can lead to inconsistent temperatures across the building. A technician can help recalibrate or replace the thermostat to ensure that your system is working properly.
8. Short Cycling
Short cycling occurs when an air conditioner turns on and off too frequently, often before reaching the desired temperature. This can happen for a variety of reasons, including an oversized unit, a clogged air filter, or problems with the thermostat. Short cycling puts extra stress on the system and can lead to increased energy costs and a shorter lifespan for the unit.
In commercial settings, this issue can affect the comfort of multiple people, making it even more important to address the problem quickly. A professional technician can determine the cause and make the necessary repairs to fix the short cycling issue.
Maintaining Comfort in Both Residential and Commercial Spaces
Air conditioning issues can arise unexpectedly in both residential and commercial properties, but understanding the common problems, such as poor airflow, refrigerant leaks, and faulty thermostats, can help you act quickly. By staying on top of regular maintenance and seeking professional repairs when needed, you can prevent these issues from worsening.
A well-maintained aircon system will not only keep your space cool and comfortable but also extend the lifespan of your unit. Address problems promptly, and you’ll ensure that your air conditioning system continues to work efficiently for years to come.
