3 AC Noises That Are Actually Warning Signs

Does your AC make unusual noises?

An AC unit is a staple in every household, especially in hotter states. The only problem is that these large devices have a lot of moving parts, making it likely that something can go wrong. Strange AC noises are the telltale sign of such, and you’ll need to contact a local AC repair service immediately to resolve the issue.

Units produce different noises, though. So, you’ll need to know which air conditioner sounds you should look out for.

Below are three of the most common noises that tell you there’s something wrong with your unit. Read on to learn what you should keep an ear out for.

1. High-Pitched Noises

When an AC or HVAC makes high-pitched squealing noises, it means that the compressor unit is failing. The compressor makes it possible for the refrigerant to circulate and help in producing cool air. If it makes a high-pitched noise, it means it reached a dangerous pressure level that the unit may not be able to contain.

It can also be because your fan belt got misplaced. This makes your blower motors squeal since they won’t function efficiently with a bad fan belt. 

When this happens, it’s best that you turn your unit off immediately. It’s much safer this way and doing so saves you from overspending on energy costs. It’s best that you turn it on again only when you’ve resolved the issue.

2. Consistent Banging and Clanking Noises

If you’re hearing loud banging or clanking noises, turn off the unit right away. This means that there’s something loose going around the unit. It can be something as small as a displaced screw or bolt, but it’s always worth looking into it.

Doing so prevents the unit from incurring further damages. If the noises are coming from the outdoor unit, it may be a sign that stray twigs and rocks may be circulating throughout the unit.

You need to call a technician to do emergency repairs on your AC unit. They’re knowledgeable enough to know whether there’s a misplaced part within the unit.

3. Gargling Noises

When your AC unit produces gurgling or bubbling noises, it means you have a refrigerant leak. When this happens, it’s possible that there’s a damaged line in your AC causing the leak. Rusted filters and holes in the capillary tubes may also be causes of the leak.

When you hear these noises, turn off the unit and keep everyone else away from the unit. Refrigerant leaks can prove fatal to humans due to refrigerant poisoning

Again, it’s best to hire professionals here. They’re properly equipped and can safely remove any refrigerant leaked from your unit.

Tips & Tricks

The Homeowner’s AC Maintenance Checklist

With spring around the corner, it’ll not take too long until the weather gets warm again. Spring cleaning is not about dusting blinds or washing windows only. It’s also a perfect time for AC maintenance.

Your AC needs upkeep, so it doesn’t bail out on you, especially during summer.

However, the tasks at hand get too tedious if you don’t follow the right approach. Your AC could end up having emergency repairs when the temperature is at its highest.

Don’t fret. Here’s a checklist you can follow to make your AC home maintenance tasks more manageable.

Remove Leaves and Debris

For ductless mini-split AC, you need to clear the area around your outdoor unit. Remove all leaves and debris around the unit, keeping it clear for at least two feet from the base.

Check the Filters

A dirty or clogged filter lowers your air conditioner’s efficiency. Most AC repairs come from neglected air filters. Before you turn on your AC for the first time after winter, it’s best to clean the filters first.

Cleaning involves turning off your furnace and pulling out the filter. If it’s dirty or clogged, you need to replace it. Even if it’s not filthy with dirt, it’s best to replace it if you haven’t done so in the past 90 days.

Clean the Fins

Use a vacuum that comes with a soft-bristle brush to clean your AC unit’s fins. Take note that these are easy to bend or crush, though, so only do light brushing. You can also use an AC fin comb designed for gentle fin cleaning.

Realign the Fins

Sometimes fins get bent during cleaning. It would be best not to leave them at this stage, though, as they’ll end up blocking airflow. Use a dinner knife that’s less than a half-inch thick to realign them.

Check the Air Conditioner Pad

Over time, the concrete pads that support your air conditioner can start to sink. It’s not a cause for alarm if it stays dry or level.

However, you could notice it sinking at an angle or pulling the lines tight. In that case, you need to have a professional inspect and adjust it.

Inspect Vents and Registers

HVAC return vent covers are also known as registers. Keeping them clean helps prevent extra dust and dirt from clogging your filter. It will also ensure that there’s no hindrance with the airflow to your HVAC system.

Cleaning them is as easy as wiping the dust and spider webs away. The unrestricted airflow on registers can help you save on energy costs.

Look for Air Leaks

Thorough AC service and HVAC maintenance include detecting and sealing these leaks. Air leaks will not only affect your AC’s performance but will increase your monthly bills.

The best way to test for air leaks is to use a stick of incense. Light the incense and hold it near the duct connections. If the smoke gets blown around, a leak is present.
