How to Quiet a Noisy Air Conditioner

No matter where you’re from or what you do for a living most people want to come home to a peaceful environment and not to a noisy air conditioner. Yet at some point, your AC will need some maintenance and might make a lot of noise to get your attention.

Below is an overview of common culprits of a noisy air conditioner and what you can do to quiet it down.

Why Is My Air Conditioner Noisy?

To know how to quiet a noisy air conditioner, you have to first know where the noise is coming from. So here are a few pointers on why your AC may have you reaching for earplugs.

1. Dirty Air Filters

When was the last time you changed your air filters? If it was around the time New Kids on the Block were touring the country, they’re likely caked with dust.

Here’s why that’s a problem: Air conditioners work by absorbing the heat and moisture from your home. That moisture condenses inside the unit, and water droplets fall into a drip pan.

If the air filters are dirty, instead of water dripping, that condensation will freeze. Layers upon layers of ice will block airflow, which will cause your air conditioner to make a loud buzzing sound.

Solve this problem by changing your filters once a month (more if you smoke, have allergy sufferers in your home, or if you have pets).

2. Dirty Coil Fins

You know that big box portion of your AC that is outside your home? (Or in a furnace closet, if you live in an apartment). That’s the condenser unit. If you look at it closely, you’ll see that the side panels have what look like vents. These are the coil fins. With time, they’ll get caked with dust. And if they’re on the exterior of your home, they’ll also likely get grass, small leaves, or tiny branches stuck in between them.

To clean them up, shut off the power source to your AC (preferably from the breaker unit) and hose them down once a year. Then use a condenser fin comb to straighten the coils to their original position.

3. Damaged Air Ducts

There are several reasons why air ducts can make your air conditioner sound like an angry rattling machine: improper installation, incompatibility with your AC unit, leaks, or because they’re covered in layers of dust. To prevent the last scenario, schedule regular HVAC maintenance. Not only will the checkups keep your ducts in optimal condition, but your AC will also work more efficiently, which translates to lower energy bills.

4. Motor Needs Lubrication

This is only an issue with older models. If you’re on a tight budget, follow these directions. Make sure to shut off the power to your AC before working on it. Keep in mind that air conditioners operate at a very high voltage, so we advise contacting an HVAC professional to take care of this issue.

5. AC Is Too Big for Your Home

If in addition to a noisy unit, you have uneven temperatures in your home, high humidity indoors, and higher than usual energy bills, you may have an air conditioner that’s too big for the size of your home. If it was a recent installation, return it and talk with an HVAC professional about the amount of BTUs (British Thermal Units) required for the square footage of your home.

6. It’s Time to Replace Your AC

No one wants to hear that it’s time to buy a new air conditioner. But the reality is that the lifespan of an AC is about 15 to 20 years. If you provide it with regular maintenance, it’ll last toward the higher end of that range. Past that timeframe, you’ll start needing frequent repairs. The loud noises (coupled with the age of your system) may be your AC notifying you that it’s time for an upgrade.
