Solved: Leaking Air Conditioning and Five Other Problems

Is your air conditioner acting strange? 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 odd noises, leaks, freezing up or another ailment—it all points to a particular culprit and requires a distinct remedy. By recognizing 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 unit.

While the symptoms are often distinct, many cooling system issues stem from problems that can be avoided by scheduling regular air conditioning maintenance. That’s because a routine Air conditioning 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 service. This helps locate potential problems before they cause malfunctions or other issues.

Here are some of the common AC problems and the indications you may see:

Why Is My Air Conditioner Leaking?

Air conditioning leaking water can be a common issue. One of the most common causes of an air conditioner leak is a clogged 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, debris or mold, water can back up and start to leak.

Another typical cause of water leaking from an air conditioner is a malfuncitoning or rusted drip pan, which can permit water to overflow and leak out of the unit. In addition, a refrigerant leak or a malfunctioning pump might 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 changing 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 conditioning is freezing up, it could be due to a variety of reasons. One frequent cause of a frozen air conditioner is reduced airflow, which can be caused by a clogged air filter, obstructed ductwork or closed vents. This sometimes causes a buildup of chilled air in the evaporator coil, causing it to freeze.

One more reason your air conditioner is frozen might be low refrigerant levels, which can cause the evaporator coil to become too 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. After the system has thawed, examine 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 professional.

Why Is My Air Conditioner So Loud?

If your air conditioner is making loud noises, it could be a signal that your AC needs service. One frequent cause of a very loud air conditioner is a malfunctioning fan motor or a failing fan belt. The loudness might 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 could have a dirty condenser coil, which can obstruct airflow and cause the system to work harder, resulting in greater 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 blowing cold air is a clogged air filter. A dirty air filter restricts airflow, causing the evaporator coil to become very cold and freeze, resulting in insufficient cool air. Another plausible cause is a refrigerant leak.

Low refrigerant levels can also cause the evaporator coil to become too cold and freeze, which can result in a lack of cool air coming from your air conditioner. Additionally, a faulty compressor or motor can also cause the AC not to blow cold air. To address this, it's important to examine the air filter and change it if necessary.

Why Can't My Air Conditioner Run or Even Turn On?

An air conditioner might not turn on because of a tripped circuit breaker or blown fuse. To fix this, check the electrical panel and reset any tripped breakers or change any blown fuses.

Another possible cause is a malfunctioning thermostat, which can keep the air conditioner from switching on. In that case, check the thermostat and substitute it with a new one, if needed. In addition, a faulty compressor, motor or capacitor can prevent the air conditioner from turning on. In this case, it's best to contact a professional to inspect and service the unit.

Why Does My Air Conditioner Make Weird Noises?

In addition to the problem of air conditioners working louder than they are supposed to, sometimes they also make weird 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. One other 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 produce hissing or bubbling noises.

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