When you hear the term “variable speed”, it is in reference to the fan motor inside the indoor air handler. This component moves the heated or air conditioned air though the ductwork in your home. Garland Heating and Air Conditioning offersHVAC systems with variable speed motors for installation. In addition, it is possible that your existing system is compatible with the motor. Contact us for further information, or ask your HVAC technician if your system is compatible. A convenient time is when you are scheduling your fall maintenance or air conditioning repair in Dallas.
Unlike conventional single-speed motors, a variable speed motor is capable of operating at a broad range of speeds …show more content…
The ideal relative humidity is between 30 and 50 percent, for optimal comfort. The consistent airflow provides improved air filtration and improved air quality.
• Energy Efficiency: Variable-speed motors consume less energy than conventional motors. For example, the variable speed motor uses approximately one-eighth the amount of electricity used for a conventional single-speed fan motor when it operates at half speed. Consequently, the variable speed motor can outlast a conventional motor, reducing the incidence, and costs of heating and air conditioning repair in Dallas.
• Zoned Systems: Variable speed motors and zoned systems are ideal partners in energy efficiency. Zoned systems enable you to control the temperature in different areas in the home. When combined with a variable speed motor that adjusts its output to the speed required, comfort is achieved along with increased energy efficiency, and reduces the need for air conditioning repair in Dallas vs. systems with a conventional fan.

However, they are not the same. The speed of each setting will not vary, but will remain the speed each setting dictates until changed to the other of the two speeds. A variable speed fan motor however, is capable of operating from 0 RPM to full speed and anywhere in between.
Your home’s heating and air conditioning system does more than simply heat or cool. The HVAC system also removes moisture from the air. In the air conditioning mode, a conventional fixed speed fan motor runs at the highest speed all of the time. This results in less removal of excess moisture from the air. A variable speed motor removes a greater amount of moisture than conventional fan motors. Because the variable speed fan operates at a slower speed when the air compressor starts up, humidity is more effectively extracted from the air.
As the air conditioning coil cools the air moving across it, the blower speed increases and delivers cold, dehumidified air in your home, with approximately 50% humidity. Once the humidity and heat loads achieve a balance, the variable speed motor will reduce its speed. However, a conventional fan motor operates at high speed continuously, resulting in retained humidity. Higher levels of humidity reduce your comfort, while the higher fan speed increases wear and tear on the HVAC system resulting in the increased incidence of heating and air conditioning repair in
