Excessive noise

Determine if it’s air noise, cabinet, duct or motor
noise – interview customer, if necessary
 Noisy blower or cabinet  Check for loose blower housing, panels, etc.
 High static creating high blower speed?

Check for air whistling thru seams in ducts,
cabinets or panels

Check for cabinet/duct deformation
 “Hunts” or “puffs” at high CFM (speed)  Does removing panel or filter reduce “puffing”?
 Reduce restriction
 Reduce max airflow
Evidence of Moisture
 Motor failure or malfunction has occurred and
moisture is present  Replace motor and perform Moisture Check
 Evidence of moisture present inside air mover  Perform Moisture Check
DO DON’T

Check-out motor, controls, wiring and
connections thoroughly before replacing motor

Automatically assume the motor is bad.
 Orient connectors down so water can’t get in

Install “drip loops”
 Locate connectors above 7 and 4 o’clock
positions

Use authorized motor and control model #’s for
replacement

Replace one motor or control model # with
another (unless an authorized replacement)
 Keep static pressure to a minimum:

Recommend high efficiency, low static
filters

Recommend keeping filters clean

Design ductwork for min static, max
comfort

Look for and recommend ductwork
improvement, where necessary, in
replacement
 Use high pressure drop filters – some have ½”
H
2
O drop!

Use restricted returns
 Size the equipment wisely  Oversize system then compensate with low
airflow
 Check orientation before inserting motor
connectors  Plug in power connector backwards

Force plugs
Moisture Check
 Connectors are orientated “down” (or as recommended by equipment manufacturer)
 Arrange harnesses with “drip loop” under motor

Is condensate drain plugged?
 Check for low airflow (too much latent capacity)
 Check for undercharged condition

Check and plug leaks in return ducts, cabinet
Comfort Check
 Check proper airflow settings
 Low static pressure for lowest noise
 Set low continuous-fan CFM

T’stat in bad location?
