Solved: Air Conditioner Leaking and Five Other Problems

Is your air conditioning acting weird? Chances are, 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 experiencing. Whether it’s peculiar noises, leaks, freezing up or another problem—it all points to a particular culprit and requires a specific fix. By identifying the specific symptoms, it's possible to figure out 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 regular 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 repair. This helps locate potential problems before they cause breakdowns or other issues.

Here are some 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 frequent issue. One of the most common causes of an AC leak is a blocked 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 come out of the unit.

Another possible reason 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. Additionally, a refrigerant leak or a busted pump could also cause water to leak from an AC unit.

It's crucial to address a leaking air conditioner right away to avoid damage to your home and make sure that your air conditioning system is functioning efficiently. Routine air conditioner maintenance, including exchanging the air filter, examining the condensate drain line and inspecting the unit for damage can help prevent leaks from developing in the future.

Why Does My Air Conditioner Freeze Up?

If your air conditioning is freezing up, it might be because of a variety of reasons. One frequent cause of a frozen air conditioner is reduced airflow, which can be caused by a clogged air filter, obstructed ductwork or closed vents. This can cause a buildup of cold 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 cause 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 air conditioner so it can thaw completely. After the system has thawed, assess 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 an expert.

Is My Air Conditioner Supposed to Be Loud?

If your air conditioner is making loud noises, it may be a signal that your AC needs service. One frequent cause of a noisy air conditioner is a damaged fan motor or a worn-out fan belt. The loudness could 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 obstruct airflow and cause the system to work harder, resulting in more 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 air conditioning system not making cold air is a clogged air filter. A dirty air filter restricts airflow, causing the evaporator coil to become very cold and freeze, resulting in not enough cool air. Another plausible cause 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. Additionally, a faulty compressor or motor can also cause the AC not to blow cold air. To rectify this particular problem, it's important to check the air filter and change it if necessary.

Why Can't My Air Conditioner Run or Even Turn On?

Your air conditioning system might not turn on because of a tripped circuit breaker or blown fuse. To correct this, look at the electrical panel and reset any tripped breakers or replace any blown fuses.

Another possible cause is a malfunctioning thermostat, which can prevent the air conditioner from starting. If that's the case, check the thermostat and replace it, if necessary. In addition, a faulty compressor, motor or capacitor can stop the air conditioner from turning on. If that's the situation, it's best to get a hold of 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 operating louder than they should, occasionally they also make strange noises.

One frequently encountered cause of weird noises is a broken fan motor or a worn-out fan belt. These two issues can cause scraping, squealing or grinding noises. Another potential cause is loose parts such as screws, bolts or bearings.

Furthermore, a clogged air filter can cause your air conditioning to make a noise similar to wheezing or whistling, while a refrigerant leak can produce hissing or bubbling noises.

As with many air conditioner woes, the root cause of uncommon noises is often something that can be reduced by regular air conditioning maintenance.
