Is your air conditioner acting weird? Chances are, it’s trying to tell you something.
The symptoms of an air conditioner’s problem can tell a lot about the kind of issue the system is experiencing. Whether it’s odd noises, leaks, freezing up or another ailment—it all points to a particular culprit and requires a unique remedy. By knowing the specific symptoms, it's more likely that you'll be able to identify the potential causes of the problem and determine the best course of action for repairing the AC.
While the symptoms are often distinct, many cooling system issues stem from problems that can be avoided by scheduling annual air conditioning maintenance. That’s because a routine AC 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 locate potential problems before they cause breakdowns or other issues.
Here are some of of the common AC problems and the indications you may see:
Why Do AC Systems Leak?
A cooling system leaking water can be a widespread issue. One of the most common causes of an air conditioner 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 clogged with dirt, debris or mold, water can back up and start to come out of the unit.
Another possible cause of 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. Additionally, a refrigerant leak or a malfunctioning pump can also cause water to leak from an AC unit.
It's necessary to address a leaking air conditioner promptly to prevent damage to your home and ensure that your air conditioning system is operating efficiently. Regular air conditioner maintenance, including replacing the air filter, taking a look at the condensate drain line and inspecting the unit for damage can help prevent leaks from occurring.
Why Does My Air Conditioner Freeze Up?
If your air conditioner is freezing up, it might be because of 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 can cause a buildup of chilled air in the evaporator coil, causing it to freeze.
An additional reason your air conditioner is frozen might be reduced 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 air conditioner and allow it to thaw completely. When the system has thawed, examine the air filter, ductwork and refrigerant levels to see if something is broken. Regular maintenance, including replacing 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 may be an indication that the unit needs service. One frequent cause of a very loud air conditioner is a malfunctioning fan motor or a failing fan belt. The racket might also be a sign the equipment has 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 block airflow and cause the system to work harder, resulting in greater noise. Additionally, a broken or old compressor can also produce loud noises from the air conditioner.
Why Is My AC System Not Blowing Cold Air?
One common cause of an air conditioner not producing cold air is a very dirty air filter. A dirty air filter limit airflow, causing the evaporator coil to become too cold and freeze, resulting in a lack of cool air. Another plausible reason for this problem is a refrigerant leak.
Low refrigerant levels might also cause the evaporator coil to become too cold and freeze, which can result in a lack of cool air coming from your AC. In addition, a faulty compressor or motor can also cause the AC not to blow cold air. To rectify the issue, it's important to check the air filter and change it if necessary.
Why Can't My Air Conditioner Run or Even Turn On?
An air conditioner might not switch on because of a tripped circuit breaker or blown fuse. To fix this, find the electrical panel and reset any tripped breakers or replace any blown fuses.
The source of the issue also could be a malfunctioning thermostat, which can keep the air conditioner from turning on. In this case, check the thermostat and change it, if necessary. Additionally, a malfunctioning compressor, motor or capacitor can keep 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 running louder than they should, at times they also make strange noises.
One typical cause of weird noises is a broken fan motor or a worn-out fan belt. These two dilemmas can cause scraping, squealing or grinding noises. Yet another 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 make 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.
