Is your AC acting unusual? 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 experiencing. Whether it’s weird noises, leaks, freezing up or another ailment—it all points to a particular culprit and requires a distinct fix. By recognizing 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 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 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 service. This helps uncover potential problems before they cause equipment failures or other issues.

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

Why Is My Air Conditioner Leaking?

Air conditioning leaking water can be a widespread issue. One of the most common causes of an air conditioner leak is a plugged condensate drain line. The condensate drain line is designed to remove unwanted moisture from the air conditioning system. When this line becomes slow or stopped up 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 broken or rusted drip pan, which can allow water to overflow and leak out of the unit. Also, 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 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, examining 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 air conditioner is freezing up, it may stem from a variety of reasons. One common cause of a frozen air conditioner is limited airflow, which can be caused by a blocked air filter, obstructed ductwork or closed vents. This can cause a buildup of frigid air in the evaporator coil, causing it to freeze.

Another reason your air conditioner is frozen might be low refrigerant levels, which can cause the evaporator coil to become really cold and freeze. Leaking ducts or cracked 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 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 amiss. Regular maintenance, including changing the air filter and having the system inspected annually by a skilled technician.

Why Is My Air Conditioner So Loud?

If your air conditioner is making loud noises, it might be an indication that it needs service. One common cause of a noisy air conditioner is a malfunctioning fan motor or a failing fan belt. The racket 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 hinder airflow and cause the system to work harder, resulting in increased noise. In addition, a defective or old compressor can also be a reason you hear loud noises from the air conditioner.

Why Is My Air Conditioner Not Blowing Cold Air?

One common cause of an air conditioner not making cold air is a clogged air filter. A dirty air filter can significantly slow airflow, causing the evaporator coil to become too cold and freeze, resulting in a lack of cool air. Another potential source of this issue 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 AC. Additionally, a faulty compressor or motor can also cause a lack of cool air. To fix this particular problem, it's important to check the air filter and change 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 repair this, find the electrical panel and reset any tripped breakers or change any blown fuses.

Another possible cause is a malfunctioning thermostat, which can prevent the air conditioner from turning on. If that's the case, check the thermostat and substitute it with a new one, if necessary. Also, a problematic compressor, motor or capacitor can keep the air conditioner from turning on. If that's the situation, 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 operating louder than they should, at times 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 produce scraping, squealing or grinding noises. One other commonly observed cause is loose parts such as screws, bolts or bearings.

Additionally, a dirty air filter can cause an AC to make whistling or wheezing noises, while a refrigerant leak can cause hissing or bubbling noises.

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