3 Common AC Noises and What They Mean in Your Lakewood Ranch Home

Lakewood Ranch AC noises

Your HVAC system is like a lot of things in your home: you don’t give it too much thought until it stops working. Often before components break down there is some indication that a problem exists.

AC noises can be a strong sign that something is wrong with your system. Do not ignore a noisy AC. Not only can it help you catch potential problems, but addressing issues can help extend the life of your system and help it run more efficiently.

Here are the three main types of AC noises and what they could mean. Keep reading to find out what steps you should take if you encounter any of these sounds in your Sarasota or Lakewood Ranch home.

1. Loud AC Noises

Loud noises in general are some of the most common people experience with their AC systems. If your unit seems to be running louder than normal, it could be due to any number of causes. For units more than 10 or 15 years old, it could be due to regular wear and tear on the system components.

Dirty condenser fins and damaged air ducts are two common culprits of a noisy AC. Loud clunking sounds could mean the motor needs lubrication, although this is less prevalent with more modern AC systems.

Fortunately, routine maintenance checks can catch many of these issues. Regular upkeep by a prominent Sarasota or Lakewood Ranch HVAC service can save you the headache and cost of major repairs down the road.

2. Screeching or Shrieking AC Noises

Screeching or shrieking sounds often have to do with motorized components, such as the AC compressor or fan motor. These could be due to rattling bearings or a loose or damaged fan belt that needs replacing. It could also be another component in the motor.

If the sounds seem to be coming from somewhere other than the unit itself, it could be a broken component. These can include damaged flower fans or obstructions in airflow in the ductwork.

3. Humming or Buzzing AC Noises

Humming noises often come from loose parts, such as pipes, that cause vibrations when your system is running. If the humming noise comes from the AC unit, it could be a problem with the capacitor or other parts of the motor.

Another common cause of humming or buzzing AC noises is a defective relay switch. This is the component that controls the flow of electricity to your unit.

A faint buzzing sound could indicate that the relay switch is failing in some way. A common problem is that it becomes stuck in the “on” position, keeping the coils energized and causing the noise. If it persists, you should have the switch inspected and (if necessary) replaced by a technician.
