Is your AC acting unusual? Chances are, it’s trying to tell you something.
The warning signs of an air conditioner’s problem can tell a lot about the type of issue the system is suffering from. Whether it’s odd noises, leaks, freezing up or another ailment—it all points to a particular culprit and requires a specific fix. By identifying the specific symptoms, it's possible to identify the potential causes of the problem and determine the best course of action for repairing the AC.
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 conditioning 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 repair. This helps uncover potential problems before they cause breakdowns or other issues.
Here are some of the top AC problems and the signals 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 air conditioner leak is a clogged 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, debris or mold, water can back up and start to leak.
Another potential reason for water leaking from an air conditioner is a broken or rusted drip pan, which can permit water to overflow and leak out of the unit. Additionally, a refrigerant leak or a busted pump can also cause water to leak from an AC unit.
It's important to address a leaking air conditioner right away to avoid damage to your home and be certain that your air conditioning system is functioning 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 Is My Air Conditioner Freezing Up?
If your air conditioner is freezing up, it might be due to a variety of reasons. One frequent cause of a frozen air conditioner is reduced airflow, which can be caused by a plugged 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 insufficient refrigerant levels, which can cause the evaporator coil to become too cold and freeze. Leaking ducts or compromised insulation can also cause the buildup of chilled air and cause the evaporator coil to freeze.
To fix a frozen air conditioner, it's important to turn off the system so it can thaw completely. After the system has thawed, check 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.
Is My Air Conditioner Supposed to Be 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 damaged fan motor or a failing 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 may have a dirty condenser coil, which can prevent airflow and cause the system to work harder, resulting in increased noise. Similarly, a broken 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 air conditioner not blowing cold air is a clogged air filter. A dirty air filter restricts airflow, causing the evaporator coil to become extremely cold and freeze, resulting in insufficient cool air. Another plausible reason for this problem is a refrigerant leak.
Low refrigerant levels may also cause the evaporator coil to become too cold and freeze, resulting in a lack of cool air coming from your air conditioning. Additionally, a faulty compressor or motor can also cause a lack of cool air. To fix the issue, it's important to inspect the air filter and exchange it if necessary.
Why Can't My Air Conditioner Run or Even Turn On?
Your air conditioning system might not turn on 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. In that case, check the thermostat and change it, if necessary. Additionally, a malfunctioning compressor, motor or capacitor can prevent the air conditioner from turning on. If that's the situation, it's best to get a hold of a professional to inspect and repair 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 peculiar 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. Another potential 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 problems, the root cause of strange noises is often something that can be reduced by regular air conditioning maintenance.
