Do you notice your air conditioner unit sounds louder than normal and then realize the noise is actually a major vibration? Excessive vibration in an air conditioner is not only disruptive but can also indicate an underlying issue. If the vibration is not addressed quickly, it might lead to more major problems or system failures. Absolute P&M Services will share some of the common reasons why an air conditioner will vibrate too much, and what action will be needed to ensure the longevity of your air conditioner unit.
Why is My AC Unit Vibrating Too Much?
There may be a number of different reasons why an air conditioner will have excessive vibrations. Some of the major culprits are:
• Loose or Damaged AC Components: Over time, screws, bolts, and other fasteners can become loose due to the system’s constant running. Components like fans, blades, and other internal motors that have become loose or unbalanced which can cause the unit to vibrate excessively.
• Faulty Motor: The motor is a major component of your air conditioner system. If it becomes misaligned or starts malfunctioning, it can result in abnormal vibrations.
• Deteriorated Isolation Pads: Air conditioning units, especially outdoor units like the condenser, are typically placed on isolation pads to minimize vibration and noise. These pads can deteriorate or become misaligned over time, reducing their effectiveness.
• Imbalanced Fan Blades: Dirt, debris, or damage to the fan blades can throw them out of balance, leading to vibration. This can be especially common in outdoor units that are exposed to the elements.
• Debris Inside the Unit: Leaves, twigs, or even small animals can sometimes get inside the unit, especially the outdoor condenser. When this happens, the debris can obstruct the normal operation and cause the unit to vibrate.
• Bent or Damaged Coil Fins: The thin metal fins around the coils can easily get bent or damaged. If these fins are obstructed, it can interfere with the airflow, causing the system to work harder and potentially vibrate.
• Improper Installation: If an air conditioning unit is not installed level or is not properly secured, it may vibrate when the unit is running. This is often a problem in window cooling units but can also be an issue with poorly installed condensers.
• Ductwork Issues: In central cooling systems, improper ductwork design or installation can cause vibrations when the system is running. Loose duct sections or ducts that are too small for the system’s airflow requirements can be particularly problematic.
• Refrigerant Issues: While less common, certain issues related to refrigerant, such as overcharging or undercharging, might manifest as increased vibrations or noises.
How to Fix an Air Conditioner that is Vibrating?
If you notice your air conditioner vibrating excessively, it is important to address the problem sooner rather than later. Prolonged vibration can lead to other components becoming loose or damaged, adding to the problem and potentially leading to more expensive repairs.
• Regular AC Maintenance: Ensure that your air conditioner is serviced regularly by a professional. They can spot and correct potential problems before they become a severe issue.
• Check for Obvious Signs: Ensure the unit is level, check for visible damage, and clear any debris around or inside the unit.
• Professional AC Services: If the vibration continues or seems excessive, call in an HVAC professional to diagnose and fix the problem. Trying to repair an air conditioner unit without the proper knowledge can lead to further damage or even void the warranties.
