Is your AC acting strange? If so, it's good to pay attention because it’s trying to tell you something.
The warning signs of an air conditioner’s problem can tell a lot about the kind of issue the system is experiencing. Whether it’s peculiar noises, leaks, freezing up or another problem—it all points to a particular culprit and requires a distinct remedy. By knowing the specific symptoms, it's possible to identify the potential causes of the problem and determine the best course of action for repairing the AC.
While the symptoms are often unique, many cooling system issues stem from problems that can be avoided by scheduling annual air conditioning maintenance. That’s because a routine AC maintenance call includes an inspection and cleaning of your system, as well as looking for any parts that may be wearing out and need replacement or service. This helps find potential problems before they cause malfunctions or other issues.
Here are some of the typical AC problems and the signs you may see:
Why Is My Air Conditioner Leaking?
A cooling system leaking water can be a common issue. One of the most common causes of an air conditioner leak is a blocked condensate drain line. The condensate drain line is designed to remove excess moisture from the air conditioning system. When this line becomes plugged with dirt, debris or mold, water can back up and start to come out of the unit.
Another typical reason for water leaking from an air conditioner is a damaged or rusted drip pan, which can allow water to overflow and leak out of the unit. Additionally, a refrigerant leak or a broken pump can also cause water to leak from an AC unit.
It's necessary to address a leaking air conditioner promptly to prevent damage to your home and ensure that your air conditioning system is functioning efficiently. Regular air conditioner maintenance, including replacing the air filter, examining the condensate drain line and inspecting the unit for damage can help prevent leaks from occurring.
Why Is My Air Conditioner Freezing Up?
If your AC is freezing up, it could be because of a variety of reasons. One frequent cause of a frozen air conditioner is restricted airflow, which can be caused by a blocked air filter, obstructed ductwork or closed vents. This can cause a buildup of chilled air in the evaporator coil, causing it to freeze.
One more reason your air conditioner is frozen might be reduced refrigerant levels, which can cause the evaporator coil to become too cold and freeze. Leaking ducts or compromised insulation can also lead to the buildup of chilled air and cause the evaporator coil to freeze.
To fix a frozen air conditioner, it's important to switch off the system so that it can thaw completely. After the system has thawed, check the air filter, ductwork and refrigerant levels to see if anything is amiss. Regular maintenance, including exchanging the air filter and having the system inspected annually by a skilled technician.
Why Is My Air Conditioner So Loud?
If your air conditioner is making loud noises, it may be an indication that the unit needs service. One frequent cause of a very loud air conditioner is a damaged fan motor or a failing fan belt. The noise might also be caused by loose parts such as screws, bolts or bearings, which can cause vibrations and rattling sounds.
A noisy air conditioner also might have a dirty condenser coil, which can obstruct airflow and cause the system to work harder, resulting in more noise. Similarly, a defective or old compressor can also produce loud noises from the air conditioner.
Why Is My Air Conditioner Not Blowing Cold Air?
One common cause of an air conditioning system not blowing cold air is a very dirty air filter. A dirty air filter limit airflow, causing the evaporator coil to become very cold and freeze, resulting in insufficient cool air. Another possible cause is a refrigerant leak.
Low refrigerant levels may also cause the evaporator coil to become too cold and freeze, resulting in a lack of cool air coming from your air conditioner. Additionally, a faulty compressor or motor can also cause the AC not to blow cold air. To fix the issue, it's important to check the air filter and change it if necessary.
Why Is My Air Conditioner Not Working or Not Turning On?
A home cooling system might not switch on because of a tripped circuit breaker or blown fuse. To correct this, inspect the electrical panel and reset any tripped breakers or change any blown fuses.
Another possible cause is a malfunctioning thermostat, which can keep the air conditioner from starting. If that's the case, check the thermostat and substitute it with a new one, if necessary. In addition, a malfunctioning compressor, motor or capacitor can keep the air conditioner from turning on. If that's the situation, it's best to contact a professional to inspect and fix the unit.
Why Is My Air Conditioner Making a Weird Noise?
In addition to the problem of air conditioners working louder than they are supposed to, occasionally they also make peculiar noises.
One frequently encountered cause of weird noises is a broken fan motor or a worn-out fan belt. These two issues can make scraping, squealing or grinding noises. One other commonly observed cause is loose parts such as screws, bolts or bearings.
Additionally, a dirty air filter can cause your air conditioning to make a noise similar to wheezing or whistling, while a refrigerant leak can cause hissing or bubbling noises.
As with a lot of air conditioner problems, the root cause of uncommon noises is often something that can be reduced by regular air conditioning maintenance.
