There are many different features to consider when you’re in the market for a new air conditioner. To decide which of those features are right for you, it’s helpful to know a bit more about what each feature does and how it might benefit your home. Today we’re going to highlight one such feature, the automatic-delay fan switch, and tell you why it’s a great thing to look for in a new cooling system!

How cool air gets stuck in your ducts

To understand the purpose of an automatic-delay fan switch, it’s best to first learn about the problem that it solves. During a cooling cycle, your system’s air handler blows air over the indoor coils. The air is cooled down and delivered to your home. When your thermostat senses that the temperature in your home is at a good level, it sends a signal to your system to shut down.
If your air conditioner does not have an automatic-delay fan switch, both your compressor and your air handler will shut off at the same time. The problem is that there is still cool and useful air in your ductwork that will end up going to waste because it will never be delivered to your home’s living spaces. That’s where an automatic-delay fan switch can help.

What is an automatic-delay fan switch?

With an automatic-delay fan switch, your air handler will continue to run for a set amount of time after your compressor shuts off. This allows your air conditioner’s fan to push all of the remaining cool air out of your ductwork and into your home’s living spaces, where it will cool down your rooms and make them feel more comfortable.

How does an automatic-delay fan switch improve your A/C’s efficiency levels?

The best thing about installing a system with an automatic-delay fan switch is that it allows your air conditioner to run more efficiently. For one, you get the maximum amount of use out of the energy that your system consumes, because all of the cool air that it generates will be put to use. In addition, there will be a long time in between your home’s cooling cycles because your rooms will stay cool longer with the conditioned air that would otherwise be wasted in your ducts.
