Tips to Keep Your Air Conditioner Running Quietly

When the weather starts warming up it is nice to have a functioning air conditioner running to help give some relief. You may have experienced how noisy these can become, either with your own unit or because of a neighbors’. What you may not know is that ignoring that noise can cause undue wear on your system.

Fortunately, there are some things you can do to reduce both the annoyance and the impact on your system. These can be grouped into two simple categories: system maintenance and sound insulation.


AC System Maintenance:

When it comes to operating a quiet air conditioner, you really want to be sure you keep up on your regular maintenance. If you have an annual tune-up, a technician in Clarksville will check on these while performing your system maintenance.


Check the Foundation

One of the first things to check is the foundation on which the outdoor unit is mounted and its stability. Is the surface solid, like concrete? Is it mounted securely so it does not move around while in operation?

The simple function of the fan will cause a lot of vibration. If it is not mounted tightly, you will get a lot of noise as it vibrates back and forth. Also, some materials it could be mounted to may actually amplify sound, such as some wooden structures. (continue below)

Check Compressor Bolts

As with the foundation you want to check the bolts holding the compressor to the unit. If these are loose, they will cause the compressor to rattle against the unit. Too much vibration will cause damage to the compressor as well as to the lines coming to it.


This is a simple fix, and just requires checking to make sure they are snug. If you start hearing rattling between tune-ups, this would be a great place to start. Just be sure that if you attempt to do it on your own, kill the power to the unit. Turn the AC off from the thermostat, as well as tripping the breaker or removing it. This is typically located near the outdoor unit on the side of the house.


Check The Fan Blade

The fan itself can be another major source of the noise. Noise from the fan is actually quite normal as it spins. However, if the fan is loose or is starting to rust, it can cause additional noise.


Check The Compressor

The compressor should not make much noise under normal operation. If you hear a clunking, humming, banging, ticking, or hissing sound, it means the air compressor has a problem. The best thing to do at this point is to call a professional HVAC technician in Clarksville to evaluate the problem.

If you do need to replace the compressor, you need a professional to do the job to properly evacuate the system and then recharge it.


Check the Fan and Unit Cage

The case that goes over the fan and around the condensation oils can begin to rust over time. When it does, it may start to vibrate. Visibly checking the cage is sufficient. If you notice rust, and especially if you notice areas that are rusted through and loose, call for an evaluation.

Depending on your unit, this may be replaceable. However, if the unit is old enough to rust through, it may be time to evaluate replacing the unit for something more efficient.

Once you have done all the maintenance tasks to ensure there are no problems with your unit, looking at options for soundproofing is next. When you do try to add soundproofing, you need to ensure the unit continues to get adequate airflow.


Use a Soundproofing Blanket

Blankets have been used for decades for various forms of sound dampening. This can certainly help reduce the normal sound of the fan running. If you are going to use a blanket, be sure you use one specifically designed for air conditioners.

Air conditioner blankets are designed to help both reduce noise as well as allow for plenty of air flow. If the air is restricted too much, it will cause the unit to overheat. Overheating the system will not only cause the system to not cool correctly but can also cause a system failure.


Fence In Your Unit

One option that has become very popular is to use a physical barrier around the outside of the air conditioning unit. This may be a simple two or three-sided fence, a lean-to, or a full shelter. The key to whatever shelter you choose is to ensure adequate airflow.

It is possible to reduce the noise that your air conditioning unit emits. Be sure your unit is in good repair, and then tackle the options for soundproofing.


Call an Experienced Professional if Your System is Malfunctioning

Do you have an extremely old system? Are you seeing or hearing things that weren’t there before? If you suspect that the system is not working properly, you should call a professional as soon as possible.

A few signs that the system is in trouble include abnormal noises or smells, an extremely cold home, expensive bills, and frequent shutoffs. Regardless of the concern, an experienced professional can solve the problem and perform the necessary repairs before an emergency occurs.

Prevention and maintenance costs are much more reasonable than having a costly repair later.
