Is your air conditioner driving you nuts? Don’t worry, a lot of people experience the frustration of a noisy AC. In the summertime, when your air conditioner is on full blast, you will experience some level of noise. This is merely the nature of AC systems, especially older air conditioners. However, there could be a number of issues that are causing your system to be even louder than usual. You could have an obstruction in the fan unit or you could be having an issue with your refrigerant levels. Here are some effective AC system noise reduction tips.
- Turn off your unit and wait for it to completely settle until you turn it back on again. Before you attempt any other methods to try and lower the noise level on your unit, you want to see if simply turning it off will do the trick. In some cases, your AC system may be working on overtime to provide your home with the cool air it needs to keep the climate regulated. If you turn on the system and the sound doesn’t come back, you most likely don’t have to worry about it again.
- Check the compressor unit for obstructions. There is also a chance that the compressor unit in your HVAC system has a blockage or obstruction. Because these units are usually outside – where they can draw the natural air – you may have a problem with leaves, small branches and twigs getting inside the fan blades. A fan blade may already be cracked and need to be replaced. If the fan is in good condition, however, you may simply be able to pull out the debris.
- Refill the refrigerant. If your AC system is making a loud clicking sound, this could be an issue with the refrigerant levels. The clicking sound is simply the AC unit trying to suck up whatever refrigerant it has left. When the refrigerant is full, you can’t hear this clicking. In most cases, you will need to hire a specialized technician to refill your unit for you, because the process can be difficult – you don’t want to cause further damage and you don’t want to injure yourself.
- Have the system professionally inspected. If you can’t seem to find the source of the sound, it could be time to call in the professionals. If you have an HVAC service agreement, you are in luck. One of the benefits of HVAC service agreements is that you can have minor issues looked at and not have to come out of pocket. However, you just never know when the issue is bigger than it seems.
- Replace the entire air conditioner. If your AC system is particularly old, it may simply be time for a new unit. Older ACs are typically noisier. Instead of waiting to see if the noise goes away, you are probably better off simply replacing the entire system. In the end, not only will a new system be quieter – it will also be more efficient.
