The Silent Sentinel: Importance of Regular Maintenance for Whisper-Quiet AC

 September 26, 2023

Everyone loves a silent AC as it contributes to their comfort aside from providing cool or warm temperatures. If you want to maintain the silent operation of your AC, you must ensure regular system maintenance.

According to https://activeplumbingandair.com, without maintenance, you cannot ensure efficient system operation, and you will also reduce your unit’s lifespan, as you will have to deal with frequent repairs and costly replacements. Here is why regular maintenance is essential for the silent operation of your AC.

Efficient Operation

AC units should operate at peak efficiency from the moment you install them. However, you should schedule regular maintenance to keep them running at peak levels. Maintenance includes the following:

  • Regular cleaning or replacement of air filters
  • Inspecting and cleaning coils
  • Checking refrigerant levels

You can do some maintenance yourself, such as cleaning or air filter replacement. However, you must call in a professional for more complex issues to avoid damaging your system.

In most cases, when you hear strange noises from your AC, you definitely need to call a professional because they are a sign of issues that cannot be handled without professional assistance.

When it comes to replacing your air filters, you can do so once every three months or depending on the type of filters you have or your home’s conditions. For example, if you are a smoker, have indoor pets that shed fur, live in a polluted area, or if the home has a lot of people, you might need to change your air filters more frequently.

Speak with a professional to implement the best AC maintenance practices and replace your air filters regularly. When it comes to cleaning, you must ensure that your outdoor unit is clear of debris and that the airflow isn’t obstructed.

When you keep your AC components clean and properly maintained, your AC unit will continue to operate smoothly, efficiently, and quietly. ACs can become noisy if they aren’t properly maintained due to dust or debris accumulation, forcing the system to work harder to operate at standard levels. When this occurs, your energy bills will be higher, and the components will be at risk of damage, making possible future repairs or replacements more likely to occur.

Reduced Wear and Tear

AC components that aren’t properly maintained will increase in wear and tear in time, leading to a noisy operation. In some instances, you will hear rattling, buzzing, or squeaking noises if you have loose or worn-out parts such as motors, belts, or fan blades.

Regularly maintaining your AC through professional check-ups or DIY will make you less likely to deal with a noisy AC. When a professional inspects your AC, they will find any issues with your unit and make timely repairs or replacements of the components. This will prevent your AC from causing excessive noise in the future.

Lubrication of Moving Parts & Detection of Potential Issues

AC systems have moving parts that require proper lubrication to operate efficiently. Without regular lubrication, the parts will become inefficient, resulting in increased friction and noise.

During maintenance, lubrication will be applied to bearings, motors, and other moving parts if needed to ensure smooth and silent operation. Yet, don’t let this aspect make you believe that your AC noise issues are related only to a lack of lubrication.

During AC maintenance, HVAC professionals will thoroughly inspect all your AC systems to identify any potential issues before they escalate into costly problems that can disrupt system operation. In many instances, other things might be wrong with your unit that aren’t related to lubrication, so do not try to proceed without professional assistance.

Cleaning of Ductwork

Your ductwork can accumulate dust, debris, and other contaminants over time. When these obstructions are present, they can and will restrict airflow. Restricted airflow will cause your AC system to work harder than before to keep up.

This will produce more noise and higher energy bills. With regular maintenance, you can expect your ductwork to be cleaned, ensuring proper airflow. This might minimize the noise generated by the system. If your AC is too old, no maintenance and repairs will make it quieter.

Calibration of Controls

In many instances, misaligned or malfunctioning controls can lead to the irregular or noisy operation of your AC system. During maintenance, your HVAC technician will calibrate thermostats, sensors, and other control components to ensure quiet system operation.

Although you can also try to change thermostat settings and see if your AC will quiet down, you should let the professionals check the sensors and other control components. You can do more harm than good otherwise since calibrating AC controls requires a certain level of expertise.

Extension of The Unit’s Lifespan

ACs are expensive and complex pieces of technology, but if you take good care of them, they will last for many years to come. The best way to do this is to ensure regular maintenance.

When you have regular maintenance and inspections of your AC, you extend its lifespan, which will also decrease the chances of experiencing unexpected breakdowns or premature failures.

You can enjoy your quiet AC unit for years to come, ensure its efficiency, and avoid costly repairs or replacements. Usually, professional maintenance should be scheduled at least once a year or as the manufacturer recommends.

When maintenance occurs, an HVAC professional will comprehensively inspect your unit, clean it, and perform necessary repairs to ensure your system’s efficiency and quiet operation.

As a homeowner, you should clean and replace air filters regularly, keep the outdoor unit free of debris, and promptly address any unusual sounds coming from your AC or performance issues by calling a professional HVAC technician.
