What causes a blower wheel to wobble?
Answer: Most of the time wobbling inside the furnace is caused by the blower wheel being out of balance. Most of the time a piece of something (filter, furnace insulation, paper, dirt) has become sucked in the blower wheel (squirrel cage) and causes it to become off balance and wobble.
Is a squirrel cage fan more efficient?
Squirrel fans are known for their superior energy efficiency compared to other types of blowers. They are also durable, reliable, relatively quiet, and capable of operating in a broad range of environmental conditions. These attributes make squirrel cage blowers a highly desired device in the HVAC industry.

Which way should a squirrel cage spin?
The fan wheel rotates clockwise or counter-clockwise, with the small forward-curved blades scooping the airflow and slinging it out as the wheel rotates. It is designed to move high-volume airflow with very little static pressure.
How do I stop my blower from vibrating?
Your leaf blower’s isolator mounts are designed to separate the harness from the blower itself. This should reduce the vibration felt by the operator during operation. Isolators are typically made of rubber, and as a result they can wear down over time.
How do I balance my HVAC system?
- Close or Open Your Register.
- Try a 2 Degree Offset.
- Check Filters for Cleanliness.
- Install Window Coverings to Prevent Heat.
- Avoid Placing Electronic Equipment Near Thermostat.
- Check for Drafts.
- Adjust Ceiling Fans.
- Prevent Airflow Restrictions.
Is axial or centrifugal fan better?
Many of you have most likely been told a characteristic of centrifugal fans is that they have higher pressure and lower airflow capabilities than axial fans. However, axial fans have higher airflow and lower pressure capabilities.
Are centrifugal fans better?
Centrifugal fans also offer distinct benefits: First-rate energy efficiency. Constant airflow allows centrifugal fans to generate energy that reaches up to 84% static efficiency. These higher efficiency levels are ideal for sustaining larger air systems.
How does a squirrel cage blower work?
Centrifugal fans use the kinetic energy of the impellers to move the air stream, which in turn moves against the resistance caused by ducts, dampers and other components. Centrifugal fans displace air radially, changing the direction (typically by 90°) of the airflow.
Which way should a centrifugal fan turn?
In these examples, the correct direction of rotation is clockwise as viewing the fans from the inlet side (as shown currently in the Figs). Using these fans in the opposite direction from that shown here will result in an increase in the fan’s power consumption, fan noise and also the air volume it moves. Fig.
How do I know if my blower is CW or CCW?
Are the Blades leaning or tilted toward Clockwise or Counterclockwise? Use the hands of a clock for reference. If they’re tilted toward Clockwise Direction, as in the picture to the left, then you have a Clockwise Forward Curve Blower Wheel.

How do I know if my blower motor is rotating?
Fan rotation is determined by looking at the fan from the drive end. The drive end is is the side of the fan housing through which the fan or motor shaft protrudes. For DWDI or Arrangement 3 SWSI fans, it is the side of the fan housing at which the belt drive sheave is mounted.
What is a furnace squirrel cage?
The type of fan which is located inside your furnace, is a forward curve, otherwise known as a squirrel cage. The tips of the blades are inclined in the direction of rotation.
Why is my furnace not blowing hot air?
The Furnace Is Blowing Cold Air
First, check to make sure the thermostat is set correctly. You will want to make sure that the fan control is set to auto, and not ‘on’. If the thermostat appears set correctly, turn off your heater at the thermostat and check the filter. If the filter is dirty, replace it.
Why is my air handler vibration?
The air handler naturally produces vibrations as it runs. These vibrations often travel through the relatively thin and reverberant walls of your ducts, contributing to excess levels of noise inside of your home.
How do you fix a vibrating furnace?
Loose parts on your furnace’s housing can cause an annoying vibration sound when the furnace is running. You can fix this problem by carefully tightening all bolts and screws on the exterior of your furnace. Check access panels to make sure they are closing properly and sitting in their frame correctly.
Why does my furnace vibrate?
It’s most likely that the cause of vibration is an unsecured blower fan or motor. Sometimes, the blower motor can shake itself loose from the mounts that hold it in place, creating a loud vibrating sound as it runs. Contact a furnace expert to reconnect the fan or motor to the mounts that keep it in place.
How do I even out the temperature in my house?
- Clean the Air Ducts. If you have leaks in your air ducts, cool air won’t make it to every air vent, resulting in uneven cooling. …
- Turn On the AC Fan. …
- Adjust the Air Vents. …
- Check the Insulation. …
- Install a Zoned System.
How do you balance the heat in a two story house?
The general rule of thumb for a two-story home is that you should set each thermostat two degrees Fahrenheit apart from the other. During the summer, when your AC is running, set the upper floor at the temperature you actually want in your home. Then set each floor underneath that to two degrees warmer.
What kind of fan pushes the most air?
A flush-mount ceiling fan with a high CFM will move the most air for you. You’ll want to look for a high-flow model that has a 7000 CFM rating at minimum if you want a lot of air movement in your room.

What kind of fan moves the most air?
A powerful floor fan is usually most effective at moving the greatest amount of air in larger spaces, but anyone who needs to save space may want to look into a tower fan with a smaller footprint.
How axial fans increase the fluid flow pressure?
In a typical axial fan, the effective progress of the air is straight through the impeller at a constant distance from the axis. The primary component of blade force on the air is directed axially from inlet to outlet and thus provides the pressure rise by a process that may be called direct blade action.
