Is your AC acting unusual? 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 type of issue the system is experiencing. Whether it’s peculiar noises, leaks, freezing up or another breakdown—it all points to a particular culprit and requires a specific fix. By knowing the specific symptoms, you can figure out the potential causes of the problem and determine the best course of action for repairing the unit.
While the symptoms are often very different, 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 finding any parts that may be wearing out and need replacement or service. This helps find potential problems before they cause malfunctions or other issues.
Here are a few of the top AC problems and the signs you may see:
Why Do AC Systems Leak?
A cooling system leaking water can be a common issue. One of the most common causes of an air conditioner 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 escape.
Another possible explanation for water leaking from an air conditioner is a broken 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 promptly to reduce the amount of damage to your home and ensure that your air conditioning system is running efficiently. Routine air conditioner maintenance, including exchanging the air filter, examining the condensate drain line and inspecting the unit for damage can help prevent leaks from happening.
Why Is My Air Conditioner Freezing Up?
If your air conditioner is freezing up, it might be due to a variety of reasons. One common cause of a frozen air conditioner is restricted airflow, which can be caused by a blocked air filter, obstructed ductwork or closed vents. This sometimes causes a buildup of cold air in the evaporator coil, causing it to freeze.
Another 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 result in the buildup of chilled air and cause the evaporator coil to freeze.
To fix a frozen air conditioner, it's important to power down the system and allow it to thaw completely. Once 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 an expert.
Why Is My Air Conditioner So Loud?
If your air conditioner is making loud noises, it may be an indication that your AC needs service. One common cause of a loud air conditioner is a broken 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 prevent airflow and cause the system to work harder, resulting in more noise. Additionally, a broken or old compressor can also cause loud noises from the air conditioner.
Why Won'y My Air Conditioning Blow Cold Air?
One common cause of an air conditioning system not producing cold air is a very dirty 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 plausible cause is a refrigerant leak.
Low refrigerant levels might also cause the evaporator coil to become too cold and freeze, leading to a lack of cool air coming from your AC. Also, a faulty compressor or motor can also cause a lack of cool air. To rectify the issue, it's important to inspect the air filter and exchange it if necessary.
Why Won't My Air Conditioner Run or Start?
Your air conditioning system 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 change any blown fuses.
The source of the issue also could be a malfunctioning thermostat, which can keep the air conditioner from turning on. If that's the case, check the thermostat and substitute it with a new one, if necessary. Additionally, a problematic compressor, motor or capacitor can keep the air conditioner from turning on. If that's the situation, it's best to contact a professional to inspect and service the unit.
Should My Air Conditioner Be Making a Loud Noise?
In addition to the problem of air conditioners working louder than they ought to, sometimes they also make strange noises.
One frequently encountered cause of weird noises is a malfunctioning fan motor or a worn-out fan belt. These two problems can produce scraping, squealing or grinding noises. Another potential cause is loose parts such as screws, bolts or bearings.
Additionally, a clogged air filter can cause your air conditioning to make a noise similar to wheezing or whistling, while a refrigerant leak can make 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.
