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

The signs of an air conditioner’s problem can tell a lot about the sort of issue the system is afflicted with. Whether it’s odd noises, leaks, freezing up or another ailment—it all points to a particular culprit and requires a distinct fix. By recognizing the specific symptoms, you can identify 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 Air conditioner maintenance call includes an inspection and cleaning of your system, as well as locating any parts that may be wearing out and need replacement or to be fixed. This helps find potential problems before they cause breakdowns or other issues.

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

Why Do AC Systems Leak?

An air conditioner 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 responsible for removing 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 typical cause of 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. Also, a refrigerant leak or a busted pump can 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 be certain that your air conditioning system is functioning efficiently. Professional air conditioner maintenance, including replacing 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 AC is freezing up, it may be due to a variety of reasons. One frequent cause of a frozen air conditioner is restricted airflow, which can be caused by a blocked air filter, obstructed ductwork or closed vents. This leads to a buildup of frigid air in the evaporator coil, causing it to freeze.

An additional 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 lead to the buildup of frosty air and cause the evaporator coil to freeze.

To fix a frozen air conditioner, it's important to switch off the system and allow it to thaw completely. After the system has thawed, examine 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.

Is My Air Conditioner Supposed to Be Loud?

If your air conditioner is making loud noises, it could 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 noise 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 greater noise. Additionally, a damaged 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 blowing cold air is a very dirty air filter. A dirty air filter can significantly slow airflow, causing the evaporator coil to become too 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, which can result in a lack of cool air coming from your air conditioner. Also, a faulty compressor or motor can also cause an air conditioner to not produce cool air. To fix this, it's important to examine the air filter and replace it if necessary.

Why Won't My Air Conditioner Run or Start?

Your air conditioning system might not start up because of a tripped circuit breaker or blown fuse. To fix this, inspect 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. Additionally, a problematic compressor, motor or capacitor can keep the air conditioner from turning on. To address this issue, it's best to get in touch with a professional to inspect and repair the unit.

Should My Air Conditioner Be Making a Loud Noise?

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

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

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

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