Solved: A Leaky AC Unit and Five Other Problems

Is your AC acting unusual? If so, it's good to pay attention because it’s trying to tell you something.

The symptoms of an air conditioner’s problem can tell a lot about the type of issue the system is afflicted with. Whether it’s peculiar noises, leaks, freezing up or another problem—it all points to a particular culprit and requires a specific repair. By identifying the specific symptoms, it's more likely that you'll be able to narrow down the potential causes of the problem and determine the best course of action for repairing the air conditioning system.

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 Air conditioner 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 to be fixed. This helps uncover potential problems before they cause malfunctions or other issues.

Here are a few of the typical AC problems and the signals you may see:

Why Do AC Systems Leak?

Air conditioning leaking water can be a frequent issue. One of the most common causes of an air conditioner 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 clogged with dirt, particles 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 allow water to overflow and leak out of the unit. In addition, a refrigerant leak or a busted pump could also cause water to leak from an AC unit.

It's necessary to address a leaking air conditioner quickly to avoid damage to your home and be certain that your air conditioning system is running efficiently. Regular air conditioner maintenance, including exchanging the air filter, checking 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 stem from a variety of reasons. One common cause of a frozen air conditioner is reduced airflow, which can be caused by a clogged air filter, obstructed ductwork or closed vents. This leads to 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 really cold and freeze. Leaking ducts or damaged insulation can also cause 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 system so it can thaw completely. After the system has thawed, check the air filter, ductwork and refrigerant levels to see if anything is malfunctioning. Regular maintenance, including changing 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 might be an indication that it needs service. One common cause of a loud air conditioner is a broken fan motor or a damaged fan belt. The racket could 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 could have a dirty condenser coil, which can obstruct airflow and cause the system to work harder, resulting in greater noise. Additionally, a damaged or old compressor can also cause loud noises from the air conditioner.

Why Is My AC System Not Blowing Cold Air?

One common cause of an air conditioner 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 potential cause is a refrigerant leak.

Low refrigerant levels can also cause the evaporator coil to become too cold and freeze, leading to a lack of cool air coming from your AC. Additionally, a faulty compressor or motor can also cause an air conditioner to not produce cool air. To address this, it's important to inspect the air filter and exchange it if necessary.

Why Won't My Air Conditioner Run or Start?

Your air conditioning system might not switch on because of a tripped circuit breaker or blown fuse. To repair this, check the electrical panel and reset any tripped breakers or switch out any blown fuses.

Another possible cause is a malfunctioning thermostat, which can keep the air conditioner from switching on. If that's the case, check the thermostat and replace it, if required. In addition, a problematic compressor, motor or capacitor can stop the air conditioner from turning on. To address this issue, it's best to get a hold of a professional to inspect and service the unit.

Should My Air Conditioner Be Making a Loud Noise?

In addition to the problem of air conditioners running louder than they are supposed to, at times they also make weird noises.

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

Furthermore, a blocked air filter can cause whistling or wheezing noises from an air conditioner, 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.
