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 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 more likely that you'll be able 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 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 uncover potential problems before they cause malfunctions or other issues.
Here are some of of the top AC problems and the signals 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 plugged 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, dust or mold, water can back up and start to leak.
Another typical reason for water leaking from an air conditioner is a malfuncitoning or rusted drip pan, which can enable water to overflow and leak out of the unit. In addition, a refrigerant leak or a malfunctioning pump could 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. Routine air conditioner maintenance, including replacing the air filter, checking the condensate drain line and inspecting the unit for damage can help prevent leaks from happening.
Why Does My Air Conditioner Freeze Up?
If your air conditioner is freezing up, it could stem from a variety of reasons. One frequent cause of a frozen air conditioner is reduced airflow, which can be caused by a blocked air filter, obstructed ductwork or closed vents. This sometimes causes a buildup of chilled 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 damaged 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 power down the air conditioner so it can thaw completely. When the system has thawed, examine the air filter, ductwork and refrigerant levels to see if anything is malfunctioning. Regular maintenance, including replacing the air filter and having the system inspected annually by an expert.
Why Is My Air Conditioner So Loud?
If your air conditioner is making loud noises, it might be an indication that your AC needs service. One frequent cause of a very loud air conditioner is a damaged fan motor or a failing fan belt. The racket could 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 might have a dirty condenser coil, which can block airflow and cause the system to work harder, resulting in increased noise. Similarly, a defective or old compressor can also be a reason you hear loud noises from the air conditioner.
Why Is My AC System Not Blowing Cold Air?
One common cause of an air conditioning system not producing 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 insufficient cool air. Another possible reason for this problem is a refrigerant leak.
Low refrigerant levels can also cause the evaporator coil to become too cold and freeze, resulting in a lack of cool air coming from your AC. Also, a faulty compressor or motor can also cause the AC not to blow cold air. To fix this particular problem, it's important to inspect the air filter and replace it if necessary.
Why Can't My Air Conditioner Run or Even Turn On?
Your air conditioning system might not switch on because of a tripped circuit breaker or blown fuse. To repair this, check 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 stop the air conditioner from switching on. In that case, check the thermostat and change it, if required. Also, a malfunctioning 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 service the unit.
Why Is My Air Conditioner Making a Weird Noise?
In addition to the problem of air conditioners operating louder than they are supposed to, occasionally they also make peculiar noises.
One typical cause of weird noises is a malfunctioning 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 whistling or wheezing noises from an air conditioner, while a refrigerant leak can cause hissing or bubbling noises.
As with lots of air conditioner woes, the root cause of uncommon noises is often something that can be reduced by regular air conditioning maintenance.
