Is your air conditioning acting strange? There's a good chance it’s trying to tell you something.
The signs of an air conditioner’s problem can tell a lot about the type of issue the system is suffering from. Whether it’s odd noises, leaks, freezing up or another ailment—it all points to a particular culprit and requires a unique fix. By knowing the specific symptoms, you can narrow down the potential causes of the problem and determine the best course of action for repairing the unit.
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 finding any parts that may be wearing out and need replacement or service. This helps uncover potential problems before they cause equipment failures or other issues.
Here are a few of the top AC problems and the indications you may see:
Why Is My Air Conditioner Leaking?
A cooling system leaking water can be a widespread issue. One of the most common causes of an AC leak is a clogged condensate drain line. The condensate drain line is is supposed to take away extra moisture from the air conditioning system. When this line becomes plugged with dirt, dust or mold, water can back up and start to leak.
Another typical explanation for water leaking from an air conditioner is a damaged or rusted drip pan, which can permit water to overflow and leak out of the unit. Also, a refrigerant leak or a broken pump might also cause water to leak from an AC unit.
It's necessary to address a leaking air conditioner quickly to prevent damage to your home and make sure that your air conditioning system is functioning efficiently. Routine 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 Does My Air Conditioner Freeze Up?
If your air conditioner is freezing up, it could stem from a variety of reasons. One frequent 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 compromised insulation can also result in the buildup of frosty air and cause the evaporator coil to freeze.
To fix a frozen air conditioner, it's important to power down the air conditioner so it can thaw completely. After the system has thawed, examine the air filter, ductwork and refrigerant levels to see if anything is malfunctioning. Regular maintenance, including exchanging the air filter and having the system inspected annually by a professional.
Why Does My Air Conditioner Make So Much Noise?
If your air conditioner is making loud noises, it may be a signal that it needs service. One prevalent cause of a loud air conditioner is a broken fan motor or a worn-out fan belt. The racket might also be the result of loose parts such as screws, bolts or bearings, which can cause vibrations and rattling sounds.
A noisy air conditioner also may have a dirty condenser coil, which can block airflow and cause the system to work harder, resulting in greater noise. Additionally, a broken 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 producing cold air is a clogged air filter. A dirty air filter limit airflow, causing the evaporator coil to become very cold and freeze, resulting in a lack of cool air. Another possible source of this issue is a refrigerant leak.
Low refrigerant levels may also cause the evaporator coil to become too cold and freeze, which can result in a lack of cool air coming from your air conditioner. Also, a faulty compressor or motor can also cause a lack of cool air. To rectify this particular problem, it's important to check the air filter and exchange it if necessary.
Why Is My Air Conditioner Not Working or Not Turning On?
Your air conditioning system might not start up because of a tripped circuit breaker or blown fuse. To correct this, look at the electrical panel and reset any tripped breakers or switch out any blown fuses.
Another possible cause is a malfunctioning thermostat, which can prevent the air conditioner from turning on. In this case, check the thermostat and substitute it with a new one, if needed. In addition, a problematic compressor, motor or capacitor can prevent the air conditioner from turning on. If that's the situation, it's best to contact a professional to inspect and service the unit.
Why Does My Air Conditioner Make Weird Noises?
In addition to the problem of air conditioners running louder than they should, sometimes they also make weird noises.
One common cause of weird noises is a broken fan motor or a worn-out fan belt. These two dilemmas can produce scraping, squealing or grinding noises. Yet another commonly observed cause is loose parts such as screws, bolts or bearings.
In addition, 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 many air conditioner predicaments, the root cause of strange noises is often something that can be reduced by regular air conditioning maintenance.
