• Circulating Air: The blower fan draws air from the return vents, passes it through the heating or cooling elements (furnace or evaporator coil), and then distributes the conditioned air throughout your home via the supply vents.
• Maintaining Temperature: By consistently circulating air, the blower fan ensures that the temperature remains consistent throughout the house, preventing hot or cold spots.
• Improving Air Quality: The blower fan also helps to filter the air, removing dust, pollen, and other allergens, contributing to better indoor air quality.

HVAC motors come in various types, each with its own characteristics and applications. The most common types include: 24 Hour Emergency Air Conditioning Service Near Me Ac Repair Man Near Me Ac Repair And Installation Near Me Air Con Repair

• PSC (Permanent Split Capacitor) Motors: These are the most common type of HVAC motor, known for their efficiency and reliability. They are typically used in residential HVAC systems.
• ECM (Electronically Commutated Motor) or Brushless DC Motors: These are more advanced motors that offer greater efficiency and control. They are often used in newer, high-efficiency HVAC systems. ECM motors can adjust their speed based on the heating or cooling demand, resulting in significant energy savings.
• Shaded Pole Motors: These are simpler and less expensive motors, typically used in smaller applications such as exhaust fans or window air conditioners.
