When your AC system was still new, there’s a very good chance that it was able to provide you with a quiet, noiseless operation. You probably didn’t even notice when the AC system was turned on. Even if you did, the noise that was produced was so minimal that it was very easy for it to blend into the background. The main point is that you were not distracted by the sounds of the operation at all, so you probably never really thought about it.

Unfortunately, as the AC system ages, it is prone to become noisy. This is particularly true if you have neglected to schedule regular AC maintenance throughout its entire lifespan. In order to quiet the noise and enjoy some silence again in your life, you’ll need to contact an HVAC company that specializes in air conditioning repair services. The HVAC technician will need to take an in-depth look at your AC in order to determine what the cause of the problem may be. From there, we’ll be able to propose several solutions that meet varying budgets and needs.

So many different factors can cause your AC to become noisy and obnoxious. In this article, we will look at several of the most popular causes that our repair technicians in Dallas, TX often find to be the culprit.

#1. Loose Components in the Compressor

One of the most easily damaged components inside an AC system is the compressor. If you hear a loud banging sounds coming from the AC, then there’s a really good chance that there’s something wrong with the compressor. This part is important as it is needed to distribute refrigerant to various parts of the HVAC system. Because there are so many moving parts involved, it is not unusual for the different parts to become loose over time. This is why it is so important to get regular AC services. Regular AC services will tighten up all these parts once again in order to make sure that the entire component is functioning properly.

Detached components inside the compressor cause the banging sound that you hear. These parts are hitting the exterior framing. If you don’t call us for air conditioning repair services as soon as possible, these parts can easily become damaged to the point where they cannot be repaired. In addition, the exterior framing can become dented and warped.

#2. Malfunctioning Fan Motor

Can you hear a ridiculously annoying screeching sound coming from your AC system? If so, this is usually an indication that there is a malfunctioning fan motor inside the outdoor condenser unit or a problem with a blower fan motor that’s inside your home. The fan motors could be broken, or they could simply be bent. Regardless, it can be difficult to really narrow down what’s wrong until the Dallas, TX air conditioning repair technician disassembles the entire unit.

Even if the fan motors are in good shape, the screeching sound is usually an indication that something associated with this part is damaged. For example, it could be that the bearings that are attached to these motors are damaged, or it could be because the belt is malfunctioning. Fortunately, the air conditioning repairs needed to correct these problems are fairly straightforward. All you need to do is replace the damaged components with new ones.

#3. Defective Contactor Relay Switch

If you start to hear a weird humming sound coming from your AC, then the problem likely lies with a defective contactor relay switch. This is an important art that is responsible for starting the outdoor condenser unit when it receives a signal from the thermostat that the temperature inside the room is too hot.

While this may seem like a simple problem, it is actually quite major, and you definitely should call us for air conditioning repair services as soon as possible. Electrical issues with the AC can always spiral out of control pretty quickly, and if you neglect to get air conditioning repair services on time, these components can actually severely damage your AC to the point where it may either need costly repairs and lots of downtimes or where it needs to be replaced. Neither situation is a situation that you want to be in.

#4. A Refrigerant Leak

All AC systems rely on some type of refrigerant to cool down the warm air that’s inside the home. You don’t usually need to top up the refrigerant unless there’s a leak somewhere in the system. Unfortunately, this tends to happen more often than you’d think. It’s easy for the coils and other components to crack. At which point, the refrigerant will start to leak out. The refrigerant will leak out even if you don’t turn the AC on; however, the problem will become exacerbated the moment that you do.

You can tell how severe the leak is by the sounds that the AC system is making. If you hear a slight hissing sound, it usually means that the leak is relatively small. Once the air conditioning repair technician has identified the location of the leak, they’ll usually be able to patch it up in record time. The problem begins when the hissing sound transforms into a gurgling sound. This means that the crack has widened and that a large amount of refrigerant is pouring out of the system.

This is definitely one of the jobs that are best left to the professionals. Refrigerant is toxic, and you definitely need to be properly trained before you should work with it. Our air conditioning repair technicians are not only properly trained but also have the right type of personal protective equipment (PPE).

#5. Sticks and Branches in the System

Now, if you hear a lot of noises with the outdoor condenser unit, then there’s a really good chance that you have some type of debris stuck inside. Since the outdoor unit is exposed to the elements, it is easy for loose sticks, dirt, or even leaves to make their way inside the condenser unit. Once they’re there, they can be difficult to get rid of. They’ll thrash around when you turn the AC on and will remain there until you remove it.

This is another reason why it is so important to schedule annual AC maintenance services. The annual maintenance will include a thorough cleaning, and our technicians will be able to easily get rid of any and all debris that may have accumulated inside the condenser unit. If not, you’ll need to keep an eye out for rattling sounds and to call a repair technician immediately. Don’t try to ignore the problem. The loose debris will smack the various parts inside the AC and can easily damage the entire system. If you don’t remove the loose debris, you might have to fork over a lot more money to replace damaged parts in the future.

#6. Damaged Drainage Line

Another common problem that you might face with time is a damaged drainage line. When this happens, you’ll start to hear some type of bubbling sounds coming from inside the AC. It’s odd and difficult to ignore. The louder the sounds, the worse that the problem usually is.

A damaged drainage line will usually mean that there’s excess moisture and humidity inside your unit. If you don’t take care of this problem as soon as possible, the components inside can also become irreversibly damaged. You’ll also notice that your AC system is no longer able to remove excess moisture and humidity from the air. It’s a bigger problem than you might have otherwise anticipated!

During the air conditioning repair service, we will take apart the entire AC system to get a better look at what the problem may be. If the crack is small, we will patch it up. The important thing here is to figure out what caused the problem in the first place. It’s important to nip the culprit in its bud to ensure that nothing similar will happen again.

#7. A Malfunctioning Thermostat

If the thermostat is malfunctioning, it can also make some annoying sounds. A malfunctioning thermostat usually presents itself as loud, annoying clicking sounds that usually are the worst when you first turn the AC unit on. You might also hear these annoying sounds at the end of a cycle. Either way, it’s important to realize that these sounds are not normal at all and that you should try to get them fixed as soon as possible.

Once again, the air conditioning repairs in Dallas, TX that are needed to deal with this problem are relatively straightforward. Your thermostat may simply need to be re-calibrated. Or, you might want to consider upgrading to a smart alternative. Smart thermostats are becoming very popular nowadays because they are energy-efficient and can help you save a lot of money and energy. These thermostats also tend to provide you with insight into your household’s needs and will improve your overall quality of living.

If you are interested in upgrading your thermostat to a new one, let the Dallas, TX air conditioning repair technician know ahead of time. This way, they’ll have all of the material needed to explain how various brands and features work. You’ll learn about geofencing technology and more. Our team will patiently walk you through the pros and cons of various thermostats, so you can make an informed decision.

#8. An Air Duct Leak

Last but not least, if you have a central HVAC system, then there’s a really good chance that you might hear some weird hissing sounds as your system ages. This is usually attributed to an air duct leak. You’ll hear the hissing sounds not only at the AC location but also throughout your home. The hissing sounds can also travel through the ducts and make their way to other parts of your home and to rooms that are not even being cooled. The sound can travel quite far with the help of the ducts.

Once again, this is a problem that’s best left to an air conditioning repair technician. They’ll be able to use video cameras and other equipment to really narrow down the location of the leak. From there, they’ll be able to figure out how severe the leak is and propose multiple solutions. When you work with our air conditioning repair technicians, you can rest assured that you will always be well-informed of all of the different solutions that are out there. We will walk you through each and every one of them, so you can be confident that you’ll always be making the best decision for your home and household.
