HVAC Systems Noise Control

Today’s HVAC systems are quieter than what we used to have. High-efficiency systems incorporate air dampers and two-stage compressors that keep the sound level low. So, if you experience some unusual sounds from your HVAC system during normal usage, don’t ignore. This could be the sign of getting the system repaired or upgraded.

Common HVAC Noises & Measures to take to maximize the Life of the System

HVAC is the heating, ventilation, and air conditioning technology used for environmental control. The HVAC system usually makes some noise. This is because the system moves a large amount of air through your room while heating or cooling it to control the natural temperature of the existing atmosphere. The normal sounds you may usually hear are low humming or a hissing sound. But, if the system suddenly starts making unexpectedly loud and unusual noises it is the time to worry. To fix the strange noises you immediately need to look for the best critical air management solutions provider. Here we will review some common HVAC system sounds and the right ways of prolonging the life of the system.

Whistling

Whistling or can say the hissing noise usually means that the air is getting away from the system. Try and listen to the sound closely. If it is coming from the room walls, this means the ducts probably are leaking. When this happens, the heating and cooling power of your system will simply blow out in the wall space instead of spreading in the entire living area.

Repairing ducts is not a DIY task. You need an expert technician to manage the task. But, if the whistling sound appears to be from the air vents, the reason could be incorrectly set air filter. You can easily repair this issue on your own by readjusting the filter.

Clicking

The clicking sound is normal. It usually appears while starting up the HVAC system. But if you notice ongoing clicking sound, there could be some issue with the thermostat or the system probably is failing some control.

Get the system inspected by your technician as early as you get those constant clicking sounds. There are many components in the system to be blamed for the sudden and continuous clicking. So it is important to get an expert technician and get the machine checked.

Rattling

Rattling sound is usually loud and many things are responsible for it to cause. There could be debris like small rocks or twigs entered inside the system if the rattling sound appears in the outdoor unit of it. To rectify this, switch off your HVAC system and also the power supply. Open the unit and remove the debris. If the issue is in the interior, calling a technician is the right option.

Rattling sound can also appear through the furnace or any other parts of your home interior. In this case, finding out the right remedy and resolving the issue becomes more difficult and complicated. Rattling sound appears due to failure or loosening of various mechanical or electrical parts. This requires an expert’s hands to analyze and repair the problem.

Squealing

Squealing sound often comes from the outdoor fan or indoor blower motors. If a mild noise comes up on the startup, it can just be some normal sound. But if it makes a high-pitched screaming like sound, turn your system off immediately and call your HVAC technician. The high-pitched squealing sound indicates that there can be a refrigerant leak. It can not only damage your system but it can also bring yours and your family’s health at risk.

Clanking

A clanking sound indicates there can be some severe issue in your HVAC system. There could be some loose parts. This means components like blades, blower motor fan, or some pipes may have slacked off. Doesn’t seem to be a big deal, but loose parts if left untreated can cause serious damage to the system. Evaluating the system, locating the loose part, and restoring the issue are not a DIY task. If a loud clanking sound appears from your system shut off the system and contact a professional technician right away.

An HVAC system is one of the costly investments. On average, this system usually lasts for fifteen to twenty years. You will never make such costly investments as frequently as other cheap purchases.
