Is your air conditioning acting weird? There's a good chance it’s trying to tell you something.

The warning 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 identifying the specific symptoms, it's more likely that you'll be able to figure out 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 routine 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 service. This helps find potential problems before they cause breakdowns or other issues.

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

Why Is My Air Conditioner Leaking?

An air conditioner leaking water can be a common issue. One of the most common causes of an AC leak is a blocked condensate drain line. The condensate drain line is designed to remove unwanted moisture from the air conditioning system. When this line becomes plugged with dirt, particles or mold, water can back up and start to leak.

Another potential reason for water leaking from an air conditioner is a damaged or rusted drip pan, which can enable water to overflow and leak out of the unit. Additionally, a refrigerant leak or a broken pump might 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 operating efficiently. Regular air conditioner maintenance, including changing the air filter, taking a look at 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 may be because of a variety of reasons. One typical cause of a frozen air conditioner is restricted airflow, which can be caused by a clogged air filter, obstructed ductwork or closed vents. This sometimes causes a buildup of frigid air in the evaporator coil, causing it to freeze.

An additional 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 cracked insulation can also lead to 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 system so that it can thaw completely. When the system has thawed, assess the air filter, ductwork and refrigerant levels to see if something is broken. Regular maintenance, including exchanging the air filter and having the system inspected annually by a skilled technician.

Why Does My Air Conditioner Make So Much Noise?

If your air conditioner is making loud noises, it might be a sign that the unit needs service. One prevalent cause of a loud air conditioner is a damaged fan motor or a worn-out fan belt. The loudness might also be caused by loose parts such as screws, bolts or bearings, which can cause vibrations and rattling sounds.

A noisy air conditioner also might have a dirty condenser coil, which can hinder airflow and cause the system to work harder, resulting in increased noise. Similarly, 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 producing cold air is a blocked air filter. A dirty air filter limit airflow, causing the evaporator coil to become very cold and freeze, resulting in a lack of cool air. Another potential reason for this problem 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 air conditioning. In addition, a faulty compressor or motor can also cause an air conditioner to not produce cool air. To address 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 turn on because of a tripped circuit breaker or blown fuse. To correct this, check the electrical panel and reset any tripped breakers or replace any blown fuses.

The cause also could be a malfunctioning thermostat, which can prevent the air conditioner from switching on. If that's the case, check the thermostat and substitute it with a new one, if required. Additionally, a faulty compressor, motor or capacitor can stop the air conditioner from turning on. In this case, it's best to get a hold of a professional to inspect and fix the unit.

Should My Air Conditioner Be Making a Loud Noise?

In addition to the problem of air conditioners running louder than they should, at times they also make strange noises.

One common cause of weird noises is a deteriorating fan motor or a worn-out fan belt. These two problems can produce scraping, squealing or grinding noises. One other possible 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 produce hissing or bubbling noises.

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