Is your air conditioning acting weird? There's a good chance it’s trying to tell you something.
The symptoms of an air conditioner’s problem can tell a lot about the kind of issue the system is afflicted with. Whether it’s weird noises, leaks, freezing up or another ailment—it all points to a particular culprit and requires a distinct remedy. By recognizing the specific symptoms, you can identify the potential causes of the problem and determine the best course of action for repairing the AC.
While the symptoms are often very different, 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 finding any parts that may be wearing out and need replacement or repair. This helps uncover potential problems before they cause breakdowns or other issues.
Here are some of the typical AC problems and the indications you may see:
Why Is My Air Conditioner Leaking?
An air conditioner leaking water can be a frequent issue. One of the most common causes of an AC leak is a plugged condensate drain line. The condensate drain line is is supposed to take away unwanted moisture from the air conditioning system. When this line becomes plugged with dirt, dust or mold, water can back up and start to escape.
Another potential reason for water leaking from an air conditioner is a malfuncitoning or rusted drip pan, which can permit water to overflow and leak out of the unit. In addition, a refrigerant leak or a malfunctioning pump might also cause water to leak from an AC unit.
It's important to address a leaking air conditioner right away to avoid damage to your home and be certain that your air conditioning system is functioning efficiently. Regular air conditioner maintenance, including changing the air filter, taking a look at the condensate drain line and inspecting the unit for damage can help prevent leaks from happening.
Why Is My Air Conditioner Freezing Up?
If your AC is freezing up, it could stem from a variety of reasons. One typical cause of a frozen air conditioner is limited airflow, which can be caused by a blocked air filter, obstructed ductwork or closed vents. This leads to a buildup of chilled air in the evaporator coil, causing it to freeze.
Another reason your air conditioner is frozen might be insufficient refrigerant levels, which can cause the evaporator coil to become very cold and freeze. Leaking ducts or damaged insulation can also result in the buildup of cold air and cause the evaporator coil to freeze.
To fix a frozen air conditioner, it's important to power down the air conditioner and allow it to thaw completely. When the system has thawed, check the air filter, ductwork and refrigerant levels to see if something is broken. Regular maintenance, including replacing the air filter and having the system inspected annually by a professional.
Why Is My Air Conditioner So Loud?
If your air conditioner is making loud noises, it might be a sign that the unit needs service. One frequent cause of a very loud air conditioner is a broken fan motor or a failing fan belt. The loudness 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 could have a dirty condenser coil, which can block airflow and cause the system to work harder, resulting in greater noise. Similarly, a damaged 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 AC not blowing cold air is a clogged air filter. A dirty air filter can significantly slow airflow, causing the evaporator coil to become extremely cold and freeze, resulting in not enough cool air. Another possible cause is a refrigerant leak.
Low refrigerant levels might also cause the evaporator coil to become too cold and freeze, resulting in a lack of cool air coming from your air conditioning. Also, a faulty compressor or motor can also cause the AC not to blow cold air. To fix this, it's important to inspect the air filter and replace it if necessary.
Why Is My Air Conditioner Not Working or Not Turning On?
An air conditioner might not switch on because of a tripped circuit breaker or blown fuse. To correct this, check the electrical panel and reset any tripped breakers or replace any blown fuses.
The source of the issue also could be a malfunctioning thermostat, which can keep the air conditioner from starting. In that case, check the thermostat and replace it, if needed. Additionally, a malfunctioning compressor, motor or capacitor can keep the air conditioner from turning on. To address this issue, it's best to get in touch with 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 running louder than they are supposed to, sometimes they also make peculiar noises.
One common cause of weird noises is a deteriorating fan motor or a worn-out fan belt. These two issues can produce scraping, squealing or grinding noises. Another possible cause is loose parts such as screws, bolts or bearings.
Furthermore, a dirty air filter can cause whistling or wheezing noises from an air conditioner, while a refrigerant leak can produce hissing or bubbling noises.
As with lots of air conditioner problems, the root cause of uncommon noises is often something that can be reduced by regular air conditioning maintenance.
