5 min read

Most homeowners often get confused between air ducts and air vents. They mistakenly believe air ducts and vents are similar and use them interchangeably. So, they don't bother about air vent cleaning Las Vegas

However, you must read this post if you call yourself a responsible homeowner. Discover the differences before understanding the reasons behind noisy air vents here.

Simply put, the ductwork of the HVAC system delivers the conditioned air. The ducts are strong enough to withstand the airflow's pressures. Their sizes can vary based on your home's layout. On the other hand, air vents are openings via which air is delivered into the room. These vents' shape and size vary depending on your HVAC system's design. 

You may hear a low hum when installing the system, which is quite normal. The problem arises right after the air vents become noisy. On that note, let's reveal the type of noises you may hear from your aircon. Most of the time, these noises indicate an issue in the air vent.

Types of Noises You May Hear from Your Air Vent

The following are the noises that you may hear from your aircon. These noises possibly indicate an issue in the air vent:

Whistling Sound –

Have you heard sudden whistling from your aircon unit? Does the sound seem like a train's whistling? If yes, it's time to take action. Such a noise may indicate clogged air filters or leaks in vents or ducts. 

Whistling might seem minor, but neglecting it will result in serious repair or complete replacement. If your unit starts making the noise, get in touch with a qualified technician to learn the reasons and fixes. 

Clicking Sound –

Clicking may occur when something obstructs the fun in your outdoor unit. It indicates loose sticks, leaves, or dirt in the outdoor unit.

Rattling Noise –

This type of noise usually happens by loose metal ducts that knock against each other. It might be a warning sign indicating gaps or leaks between the vents. 

Hissing Noise –

When your aircon starts hissing, it might indicate there are problems in the air duct or vent. It might indicate that the air filter isn't compatible with the system. You must seek consultation from a professional for air vent cleaning Las Vegas.

Bubbling Noise –

The AC connected to your home might make a bubbling noise because of excess moisture. It might produce a crack, blockage, or crack in the drainage pipe. 

4 Times When You Need to Consult a Professional for Air Vent Cleaning 

There's not one reason why your air vents might make loud noises. These vents might be partially or fully blocked. Or the air filter might become worn down or clogged. The ducts might also become loose in a few situations. You may hear noises when the ducts are too narrow, or there's something wrong with the HVAC unit's motor. Compiled below are the causes of loud noises from the aircon:

  • Blocked Vents

Blocked vents are caused either by furniture or debris. The best fix is by cleaning the air vents. Consult the professional team for the air vent cleaning service Las Vegas.

  • Worn out Air Filters

Air filters purify the air inside the room. Worn-out air filters might become clogged and worn out if not maintained properly. As a result, the air is unable to move, and vents make buzzing, whistling, and thumping noises.

  • Air Ducts Clogged

Air ducts transfer the air to and from the HVAC unit and circulate it in the house. When left unclean, they may get clogged. So, the air's path to move to and fro becomes narrower. As a result, they might make buzzing, flapping, or rattling noises. Consult a professional for air vent cleaning.

  • Ducts Are Loose or Narrow

Rattling or clanking noise from your vents indicates loose ducts at joints. In other instances, air ducts in the house are wide enough for air to pass. The increased air speed doesn't have enough room to flow. As a result, it causes noise. 

Finally-

So, these are when you need professional air vent cleaning Las Vegas. Consult an expert team that has experience and expertise in cleaning. Ensure that the team offers emergency services with round-the-clock and prompt response times.
