We have all had that feeling when we are home alone that someone else was sneaking around upstairs or in the basement. Every house makes noises that can trick the imagination into thinking something scary is lurking around the next corner, but for the most part, these noises can be ignored. However, if you have an old furnace with a traditional single speed motor in it, you may find that the sound of the furnace kicking on is one noise you simply can’t ignore. It is a whooshing, whistling noise that rattles through the ducts until your mind can tune it out. For many, the noisy furnace even interrupts their sleep, and at some point they decide they have had enough!
Why is My Furnace So Noisy?
The reason why furnaces with these types of motors are so noisy is because they only run at one speed: high speed. There is no in between and there is no time wasted working up to top speed. Instead the fan immediately starts up and a sudden blast of air is pushed out into the home creating the noise that wakes you in the night. This problem can be solved with a simple fan upgrade or you would make sure that your next furnace is built to not experience this problem.
Quiet and Energy Efficient Furnace Retrofit
Variable speed blower motors are the perfect retrofit replacement part for your furnace. If your unit still has several good years left in it, this simple upgrade can reduce the excess noise created by the unit and boost its energy efficiency. These motors ramp up to speed when the unit kicks on and ramp down once the cycle is over. This decreases the noise created by the motor, and as added benefit conserves energy. This motor can also adjust to the needs of the home. It doesn’t have to always run on high speed if it can meet the temperature needs without doing so. Overall you will experience a quieter and more efficient furnace, and when it comes time to replace the furnace, almost all high efficiency furnaces come with one of these motors built in from the start. Switch to variable speed this winter and enjoy the many benefits these motors can bring
