Most blower wheels need to be pulled and cleaned every 3-5 years, depending on usage and the home. A dirty blower wheel can negatively affect the airflow in your HVAC unit, causing your heat exchanger to overheat and AC coils to freeze. It will also reduce the efficiency of your blower motor and your entire system.
What happens if a blower wheel is dirty?
If the blower wheel get dirt or grease built up, it can slow down the wheels rotation and reduce the amount of air your blower motor is capable of moving through your home. Any dirt on those blades will cause your blower motor to work harder. This draws more amperage and pushes less air.
Is furnace blower cleaning necessary?
Three parts of the air-moving system should be kept clean:the filter, the blower, and the blower motor. Dirt is the biggest enemy of your furnace. It can waste fuel and drastically lower efficiency. Dirt affects all three basic components of your furnace, so cleaning is the most important part of regular maintenance.

What is a furnace blower wheel?
A blower wheel has blades that are specifically designed to push air through the duct system into conditioned spaces. Your heat exchanger depends on cooler air moving across it to keep it from overheating, while your air conditioner coil depends on warmer air to keep it from freezing.
What does a furnace tune up consist of?
Inspection of the heat exchanger, gas pressure and flame operation. Indoor air filter cleaning or replacement. The cleanliness of your air filter affects both the energy efficiency of your furnace and your indoor air quality. Regular cleaning or replacement is essential to keep your furnace running smoothly.
What happens when evaporator coils are dirty?
An extremely dirty evaporator coil can cause your AC to breakdown completely. This happens when condensation forms on the dirt and then freezes during the AC's operation. The buildup of frost stops the heat transfer with the air in your home, which causes the air conditioner to stop cooling air at all.
What is a blower wheel on a furnace?
A blower wheel has blades that are designed to push a given amount of air in and out of the furnace system. These blades can trap a staggering amount of dirt in the process causing the blower motor to work extra hard to spin the wheel.
How much does a blower cost for a car?
How do I know if it's the blower motor or the resistor?
Typically, if the fan will work on some speeds but not on others, the resistor is suspect. Okay, let's say there's no melting going on, but your fan doesn't work on all speeds. Typically, if the fan will work on some speeds but not on others, the resistor is suspect.
What does it mean if your furnace is squealing?
A high-pitched squeal coming from your furnace is usually the result of an issue with the blower. The blower in your furnace is powered by a motor, which has bearings that can wear out because of age or overheating. Overheating is usually caused by dirt buildup or a bad capacitor.
How do I lubricate my furnace blower bearings?

What maintenance does a furnace need?
Some of the specific tasks involved in our furnace maintenance checklist include: Inspecting the vent system and air intake grilles, removing any blockages. Checking the heat exchanger for signs of damage or corrosion. Examining and cleaning the blower, removing any debris.
Can I use compressed air to clean my furnace?
