Is your AC 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 kind of issue the system is suffering from. Whether it’s weird noises, leaks, freezing up or another ailment—it all points to a particular culprit and requires a distinct fix. By identifying the specific symptoms, it's possible 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 distinct, many cooling system issues stem from problems that can be avoided by scheduling routine air conditioning maintenance. That’s because a routine Air conditioner 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 uncover potential problems before they cause breakdowns or other issues.

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

Why Is My Air Conditioner Leaking?

Air conditioning leaking water can be a common 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 excess moisture from the air conditioning system. When this line becomes slow or stopped up with dirt, particles or mold, water can back up and start to leak.

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

It's important to address a leaking air conditioner promptly to prevent damage to your home and ensure that your air conditioning system is running efficiently. Regular air conditioner maintenance, including changing the air filter, examining the condensate drain line and inspecting the unit for damage can help prevent leaks from developing in the future.

Why Is My Air Conditioner Freezing Up?

If your AC is freezing up, it could 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 can cause a buildup of chilled air in the evaporator coil, causing it to freeze.

Another 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 compromised insulation can also cause the buildup of frosty air and cause the evaporator coil to freeze.

To fix a frozen air conditioner, it's important to turn off the air conditioning and allow it to thaw completely. When the system has thawed, assess the air filter, ductwork and refrigerant levels to see if something is broken. Regular maintenance, including changing the air filter and having the system inspected annually by an expert.

Why Is My Air Conditioner So Loud?

If your air conditioner is making loud noises, it might be a sign that your AC needs service. One frequent cause of a loud air conditioner is a malfunctioning fan motor or a damaged fan belt. The loudness can 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 obstruct airflow and cause the system to work harder, resulting in greater noise. Additionally, 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 very cold and freeze, resulting in not enough cool air. Another possible source of this issue 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 air conditioner. In addition, a faulty compressor or motor can also cause an air conditioner to not produce cool air. To fix this particular problem, it's important to examine 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 fix 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 switching on. If that's the case, check the thermostat and change it, if needed. Also, a faulty 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 fix the unit.

Why Is My Air Conditioner Making a Weird Noise?

In addition to the problem of air conditioners running louder than they ought to, sometimes they also make strange noises.

One common cause of weird noises is a deteriorating fan motor or a worn-out fan belt. These two issues can make 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 produce hissing or bubbling noises.

As with a lot of air conditioner predicaments, the root cause of odd noises is often something that can be reduced by regular air conditioning maintenance.
