When used for the right purposes, a register booster fan can make your home heating and air conditioning system work better — allowing your warm and cool air to reach you make a difference in how comfortable you are in your home. But what are these misunderstood devices actually supposed to do?
When your home’s HVAC system generates warm or cool air adequately but you have ductwork problems that prevent you from feeling that air in the places where you sleep, eat, work or relax, you can enhance the performance of your system with one or more register boosters. If you don’t have any air coming out of a vent at all or the air isn’t the right temperature, one of these devices won’t help.
The best register booster fan is a simple device that does nothing more than pull the air conditioned or heated air from your vents further out into the room, perhaps blowing it onto you to increase your comfort. These devices can be powered with a battery or in other ways, but the electric ones are the most dependable and the most powerful. That means, of course, that you’ll need a power outlet near the location of the vent.
When you see negative reviews about particular register booster fans online or hear people saying that they didn’t work for them, consider whether they’re using them correctly. They don’t work well in lowering or raising the overall temperature of your home — although they can do that in some cases — and they can’t make the air coming out of your vents cooler or warmer. But they do a great job of getting the air your system is generating to where you are and to other places where you can benefit from it most.
When you understand what register booster fans do, you can better understand which model is right for you.
