Why is my AC making Noise? | American Home Shield

Many homeowners often wonder why their air conditioning unit makes noise even when it is off, but it can sometimes go away by itself! This article will discuss and address many reasons why this happens and offer some solutions to help you avoid it happening again! The first step is identifying where your noise may be coming from, for example, if an area of your home or property is less insulated.

The second step is identifying where the noise may be staying; for example, in a certain area of your home or property.

The third step is ensuring the issue does not happen again by addressing or finding where the issue was and removing or repairing the problem causing the issue. You can either do this yourself to avoid any costs, hire a professional to help with any environmentally-unsafe problems, install new AC parts to allow it to work better on its own, or use a cooling tower that will circulate air throughout your home by connecting numerous vents to one central location.

1. The Blower May Be Loose



The blower is a part of the air conditioner that allows air to be blown into other rooms within the home, so if it falls off or becomes loose, it will make loud noises, which may cause concern for your neighbors and you. If this happens to your AC unit, you may try adding washers to the screws securing the blower cap, and tightening them slightly. If this does not work, remove the screws and reattach them with new washers under them. 

2. The Thermostat May Be Defective



If you have a defective thermostat, it may be stuck in the “on” or “off” position, which will then cause your air conditioner to turn off prematurely. While this is not harmful to your unit, it can make a lot of noise and stay on longer than it should. Reach out to a professional to get your AC repair.

3. The Air Ducts May Be Blocked



If the air ducts are blocked with debris, dirt, or lint, this can also cause your AC unit to run continuously, even when it’s off. This will also cause your AC unit to make a lot of noise while running, even when it’s off. The best way to unblock your air ducts is using a vacuum cleaner, followed by a water hose to remove any standing water or dirt that may have built up.

4. Your Refrigerant Levels May Be Too Low



Your refrigerant levels allow your AC unit to work; these should be checked annually and refilled if needed. If your refrigerant levels are too low, this can cause your air conditioner to make a lot of noise while it is running and eventually stop working. The best way to check your refrigerant levels is by checking the refrigerant level window on your AC unit.
