HVAC Variable Speed Blower Motors Coupled with Two-stage Compressors

Cut Heating and Air Bills – Improve Comfort

Las Vegas Air Conditioning Repair

New Heating Ventilating and Air Conditioning (HVAC) technology available to Las Vegas residential and commercial air conditioning clients can seem as though it is more expensive to purchase up front, however, the benefits far outweigh the purchase price. The new HVAC technology can virtually pay for itself over time. The benefits are quite noticeable by the increased efficiency that is generated by the variable speed blower motors and the energy savings which generate each month.

Conventional Las Vegas air conditioning systems systems are not able to generate these benefits because they are designed to maintain comfort based on a peak load of 95 degrees Fahrenheit out side temperature, with 75 degrees Fahrenheit and 50 percent relative humidity inside. This translates to the following: even when the temperature outside is 80 degrees Fahrenheit the air conditioner or heat pump system will remain operating full blast as if it were 95 degrees Fahrenheit outside.

For example, imagine you have a car that only drives at one speed. It would definitely get you to where you want to go, but, the way it gets you there would not be very efficient. Both Trane and Carrier HVAC systems have specifically designed their systems to include variable speed blowers for greater efficiency and humidity removal. Due to the benefits and popularity of these models, other manufacturers have since followed their lead.

Variable speed motors (technically called an ECM or an Electronically Commutated Motor), coupled with two-stage compressors and multi-stage furnaces on Las Vegas air conditioning systems, offer better control and efficiency by helping your system run at the appropriate speed to meet the current load demand. These benefits arise because using the variable speed motors forces the temperatures to remain even and forces the equipment cycles per hour to be greatly reduced. The technology behind this creation was designed to only operate and consume enough energy to meet the current demand. Therefore, in both the summer and winter months, the motor runs at a lower speeds until the demand increases, then it ramps up to meet that higher demand. Other benefits to having variable speed motors are:

The soft-start capabilities and quieter operation. Research indicates there is up to 50 percent less noise than conventional blowers. Better humidity control means the less humidity there is in the room, the cooler the room will be. On higher SEER (Season Energy Efficiency Ratio) condensing units, variable speed motors are used for the condenser fan motor. The higher the SEER the greater the energy savings. When used in conjunction with multistage furnaces, AFUE (Annual Fuel Utilization Efficiency) ratings increase. The higher the AFUE the higher the energy efficiency which equals higher savings.

The refrigerant charge in your Las Vegas air conditioning system is benefited by the variable motor speed because keeps the refrigerant operating correctly. The refrigerant is important because it helps to operate the air conditioning unit. The function of the refrigerant is to move heat from outside to the inside of the home. It removes heat and provides cooling to the compressor. It also lubricates the compressor with oil.
