Why Is My Window Air Conditioner Gurgling? Here’s The Shocking Truth!

If you’re wondering “why is my window air conditioner gurgling,” you’re not alone. This is a common problem that can be caused by a variety of factors. In this blog post, we’ll explore the most common causes of gurgling in window air conditioners and provide you with some tips on how to fix the problem.

Causes of Gurgling in Window Air Conditioners

There are several reasons why your window air conditioner may be gurgling. Some of the most common causes include:

• Low refrigerant levels: This is the most common cause of gurgling in window air conditioners. When the refrigerant level is low, the compressor has to work harder to circulate the refrigerant, which can cause it to make a gurgling noise.
• Dirty condenser coils: The condenser coils are located on the back of the air conditioner and they help to dissipate heat. If the condenser coils are dirty, they can restrict the flow of air and cause the compressor to overheat, which can lead to gurgling.
• Clogged drain line: The drain line is responsible for draining condensation from the air conditioner. If the drain line is clogged, the condensation can back up and cause the air conditioner to gurgle.
• Loose or damaged compressor: The compressor is the heart of the air conditioner and it circulates the refrigerant. If the compressor is loose or damaged, it can cause the air conditioner to make a gurgling noise.

How to Fix a Gurgling Window Air Conditioner

If your window air conditioner is gurgling, there are a few things you can do to try to fix the problem:

1. Check the refrigerant level: The first step is to check the refrigerant level. You can do this by looking at the sight glass on the side of the air conditioner. If the sight glass is clear, the refrigerant level is probably okay. If the sight glass is cloudy or bubbly, the refrigerant level may be low.
2. Clean the condenser coils: The next step is to clean the condenser coils. You can do this by using a vacuum cleaner or a brush. Be sure to clean the coils both inside and out.
3. Clear the drain line: If the drain line is clogged, you can try to clear it by pouring a cup of hot water down the drain. If the hot water doesn‘t clear the clog, you may need to use a drain snake.
4. Tighten or replace the compressor: If the compressor is loose or damaged, you may need to tighten it or replace it. If you’re not comfortable doing this yourself, you can call an HVAC technician for help.

How to Prevent Gurgling in Window Air Conditioners

There are a few things you can do to help prevent gurgling in window air conditioners:

• Keep the air filter clean: A dirty air filter can restrict the flow of air and cause the compressor to overheat, which can lead to gurgling. Be sure to clean the air filter regularly according to the manufacturer’s instructions.
• Clean the condenser coils regularly: Dirty condenser coils can also restrict the flow of air and cause the compressor to overheat. Be sure to clean the condenser coils regularly, especially if you live in a dusty area.
• Keep the drain line clear: A clogged drain line can cause condensation to back up and cause the air conditioner to gurgle. Be sure to keep the drain line clear by pouring a cup of hot water down the drain regularly.

When to Call an HVAC Technician

If you’ve tried all of the above and your window air conditioner is still gurgling, it’s time to call an HVAC technician. A qualified HVAC technician can diagnose the problem and make the necessary repairs.

Troubleshooting Tips

Here are a few additional troubleshooting tips that may help you fix a gurgling window air conditioner:

• Check the power supply: Make sure that the air conditioner is plugged into a working outlet and that the power cord is not damaged.
• Reset the air conditioner: Sometimes, resetting the air conditioner can fix a gurgling problem. To reset the air conditioner, simply turn it off and then turn it back on.
• Contact the manufacturer: If you’ve tried all of the above and you’re still having problems, you can contact the manufacturer of the air conditioner for help.

The Bottom Line

Gurgling in window air conditioners is a common problem, but it’s usually not a serious one. By following the tips in this blog post, you can troubleshoot the problem and fix it yourself.
