Is your HVAC system downright noisy? That can be a problem. There are a number of reasons why an HVAC system runs so loud that it grates on your nerves. Read on for some smart HVAC solutions to your noisy system.
Why Is My HVAC System So Noisy?
It’s possible the system you have installed is just a noisy one. HVACs are rated in decibels, according to their noise level. If you have a system that wasn’t rated for low noise production, you may be stuck. Some features of the quietest systems are:
- Variable speed blower fans, which operate at different speeds so it’s not always running full speed.
- Noise-reducing fan blades are new technology that help reduce the noise level overall.
- Compressor insulation traps noise so it doesn’t enter the home. Compressor mounting materials can also limit noise.
Quieting Your Air Ducts
Sometimes air ducts are to blame for the high noise level that occurs when your system turns on.
- Air ducts may vibrate or boom loudly from contracting and expanding when the air rushes through. You may be able to reduce the noise by wrapping them in insulation. Consult your HVAC tech about other materials specifically designed to reduce ductwork noise.
- Adjust fan speed. Your installer may not have set the fan speed properly, and it needs an adjustment to deliver the right amount of air to the ducts. This sometimes helps to reduce noise from ducts.
- If ducts were not sized properly during your installation, they may be generating noise through static pressure. Your may need to add ductwork.
- Adding a bypass duct can help relieve pressure and reduce noise in a multi-zone system.
- You can reduce static pressure (and sometimes the noise that goes with it) by increasing the amount of return air going into the system by adding or expanding grilles and registers.
- You may need to install high velocity registers and grilles to allow more air flow and lower static pressure.
