Don’t Forget This Setting on Your HVAC to Prolong Its Life

A person adjust their HVAC thermostat on the wall.

Your HVAC system is the unsung hero that keeps your home comfortable throughout the year. From providing cozy warmth in the winter to refreshing coolness in the summer, it’s a true workhorse.

But did you know that there’s a simple setting that can make a world of difference in prolonging its life? We’re talking about the fan setting on your HVAC system.

Setting your fan to “auto” instead of having it continuously running can be a game-changer for your HVAC’s longevity. This setting allows your HVAC unit to run only when it’s needed rather than all the time.

Before we get into the nitty-gritty, let’s talk about the two main fan settings on your HVAC system: “auto” and “on.” These two choices (as well as “off”) are your HVAC fan options.

Using small fans is a great way to maintain airflow without adding work for your HVAC unit.

When you set your fan to “on,” it runs continuously, even when the heating or cooling cycle is not active. The fan will keep circulating air throughout your home non-stop much like any other type of fan does.

On the other hand, when you choose the “auto” setting, the fan operates only during the heating or cooling cycle. Once the desired temperature is reached, the fan automatically turns off until the next cycle starts.

If you’re wondering if the auto setting is really worth it, you might want to consider a few things. First, think about energy efficiency. Opting for the “auto” setting can significantly reduce your energy consumption, resulting in lower utility bills and reduced strain on your HVAC system. This is a great advantage.

You also get a much quieter HVAC operation when you use auto. If you hate the constant hum of a running fan, choosing “auto” will be music to your ears. Once your home reaches the desired temperature, the fan will gracefully bow out, leaving you with a peaceful and quiet environment.

Perhaps most valuably, you increase your HVAC lifespan. HVAC systems are designed to handle cycles of operation. Continuous running can lead to more wear and tear, more repairs, and a shortened life of your system.

By using the “auto” setting, you give your HVAC a well-deserved break in between cycles, helping it live longer and perform better.

As with many things in life, there are exceptions to the rule. For instance, if you suffer from allergies or have air quality concerns, running the fan continuously may help filter the air more effectively. It’s essential to consult with an HVAC professional to determine the best setting for your specific needs.

In most cases, by choosing “auto,” you’ll enjoy energy savings, quieter operation, and a longer-lasting HVAC system. So, the next time you’re adjusting your thermostat, remember this simple yet powerful tip to reap all the benefits.
