The heating and air conditioning industry was pushed to integrate the variable speed motors for AC units to fulfill its customers’ desire for higher efficiencies, better comfort, and improved air quality. But the response to purchase the new model was not good as much as the industry expected, particularly among the residential industry. Until around the late 90’s, the variable speed motors were not in use in the residential arena. May be the reason was price.
Well, aren’t they worth the price? For a long time, the single speed blower motor was in used in the housing area. The standard system would turn on and off abruptly so you might experience temperature swings. Then the multi-speed blower motor came next to the industry along with a huge step up compared to the single speed. And finally, the heating and air conditioning industry introduced the variable speed motors for AC units.
The main distinction between the multi-speed and variable speed blower motors is that, the variable speed system contains a blower motor that is capable of moving at a range of speeds to precisely control the movement of heated and cooled air throughout the ductwork of your home.
Now why you should use the variable speed motors in your heating and air conditioning systems? Variable speed motors allow an air conditioner to do a lot, including higher energy savings, home comfort, and improved air quality.
The first reason to use the variable speed motors is the higher efficiencies. The system with variable speed motors plays a unique role despite of whether its summer or winter, which can help you lower your energy costs by reaching the high-efficiency. The variable speed motor can rise up or down to the necessary speed level that may requires for your home, which means no unnecessary energy will be used by the variable speed blower.
The second reason is the better comfort in your home. If you ever lived in a home with a standard air conditioner, then you know when standard system in use at full speed makes a lot of noise. But the air conditioner with variable speed system is opposite to the older system that sounds like a cargo train every time when it starts. A system with a variable speed motor starts very smoothly, even the homeowner doesn’t notice its start up in most cases. Your system with a variable speed motor, the temperature in your home hardly varies. Moreover, it does not immediately start blowing really warm or cold air.
Better Air Quality
The last reason of choosing the system is better air quality. If more air passes, you will get more clean air in your home. When the system with variable speed motors runs, it drags air from into the system, passes air through the air filter and throws air back into your home. Depend on the filter quality; your blower will clean the air in every minute. Since you can run the variable speed motor constantly with very little noise and cost, you can clean your house air continuously with less effort.
