Running an HVAC fan continuously to save energy while heating and cooling your home sounds counterintuitive. In fact, many Oregon residents might think that constantly running the HVAC fan is a bad idea, but there are some advantages to consistently keeping the fan turned on. 

Sky Heating, AC, Plumbing, and Electrical is your local Oregon HVAC service center, providing what you need to keep your system in top shape year-round. If you have questions about your heating and cooling system, such as “Should my HVAC fan run all the time?” or need furnace or AC repair or replacement, contact us for help.

Read on to explore some of the benefits of running your HVAC fan continuously in the temperate Oregon climate and how to set it properly. 

Why Run Your HVAC Fan Continuously?

While a furnace that won’t stop may signal a technical issue, setting the fan to “ON” at the thermostat may be best practice, depending on your furnace. Newer models are designed to stay on day and night.

Why should you run your HVAC fan continuously? The following are some of the hidden benefits.

Hidden benefit #1: Improved indoor air circulation

One of the biggest benefits of HVAC fans is proper air circulation. Heated and cooled air doesn’t always circulate properly because heat rises and pushes cold air to your house’s lower areas while making upper floors and attics very warm. Running the fan evens out temperatures throughout all spaces in your home, circulating warm and cool air for more even — and faster — residential heating and cooling.

The Dalles, Portland, and the Tualatin area are famous for their rainy, temperate climate. Mold and mildew can flourish in these conditions without good airflow. Better air circulation greatly reduces the chances of these contaminants growing in the walls, cracks, and crevices of your home.

Hidden benefit #2: Enhanced energy efficiency

With new HVAC systems, keeping the fan on actually improves energy efficiency. HVAC fan settings in newer models make automatic adjustments, keeping the temperature in your home even, which, in turn, reduces the amount of time your furnace or air conditioner needs to stay on to maintain your ideal temperature. 

Energy Star rated furnaces and air conditioners are more likely to save you money on your energy bills while running 24/7, and they reduce greenhouse gas emissions and the demand for importing energy.

Hidden benefit #3: Consistent indoor air quality

Better air circulation in your home benefits people with allergies, pets, and respiratory conditions because the air in your house makes more passes through the system’s filters, catching any allergens, bacteria, viruses, pollen, mold spores, dust, and other airborne particles.

You might have to change the filters more often if you run the HVAC system constantly, but you will also enjoy higher-quality indoor air.

Hidden benefit #4: Reduced wear and tear on your HVAC system

Contrary to popular belief, keeping your HVAC fan on may extend its service life, provided the equipment was properly installed and your ductwork is correctly sized. Set to off, a newer, energy-efficient HVAC system goes through more wear and requires more maintenance than if the fan is set to the “on” position.

Hidden benefit #5: Improved comfort in all seasons

Your HVAC system’s only job is to keep you comfortable. With the fan set to the “on” position, your home’s interior will have consistently fresh, conditioned air at your desired temperature without you having to monitor the thermostat or manually adjust the temperature. 

You’ll also get a more even temperature distribution, especially if your house has more than one floor. In the hot Oregon summers, your entire space will stay cool. In the chilly winters, you won’t have to worry about cold spots in the house. 

When To Avoid Running Your HVAC Fan Continuously

There are a few reasons you should not keep your HVAC fan running continuously. For example, if your ductwork is in the attic, the summer heat can make running the fan impractical. Temperatures well above 100°F can end up blowing down into your main living space. It also won’t help if your ductwork is leaking. Make sure to have your ducts tested and sealed occasionally so your HVAC system is as efficient as it’s designed to be.

Another consideration is the age of your HVAC system. If you’re concerned about constant fan use and energy consumption, it could be a good idea to install a more efficient motor. Older furnaces tend to use permanent split capacitor (PSC) type motors. However, a new, more efficient electronically commutated motor (ECM) can cut energy use despite running more often.

How To Set Your HVAC Fan for Continuous Operation

While each HVAC system is built differently, setting your fan to run continuously through the thermostat should be fairly easy. The “on” setting keeps the fan running even after the air reaches your desired temperature. Select this setting rather than the “automatic” setting, and the system will actively push the already-conditioned air around in your house 24/7, keeping it evenly heated or cooled with clean, filtered air year-round.
