HVAC Blower Motor / Wheel Replacement

Hard at work inside your heating or cooling system, there’s a part called the blower wheel (mounted on the shaft of the blower motor). This device pushes large amounts of warm or cold air throughout your ductwork to keep you comfortable. If the blower motor or wheel becomes damaged or wears out with age, it can stop in its tracks, causing your HVAC system to fail.

Time for a Blower Motor / Wheel Replacement

Why do blower wheels fail? There are several causes. Over time, dirt, dust, and buildup can pollute your blower wheel, which slows it down. It can also become unbalanced leading to vibration, metal fatigue and eventually failure. Blower motors can fail due to electrical defects, overexertion of energy, or worn bearings from an unbalanced blower wheel. In any of these cases, it’s time for a blower motor and wheel replacement.

Signs it’s time for a new blower motor and wheel

You might spot some issues that indicate it’s time to get the blower motor and wheel replaced. Look out for the following symptoms:

  • Excessive vibration from the equipment

  • Motor is loud on startup and struggles to get up to speed
