Why Should Blower Activation Be On or Off on Aprilaire?

From my experience, deciding whether the blower activation should be on or off on an Aprilaire system is crucial for both comfort and efficiency. When the blower activation is on, the fan runs continuously or at set intervals, which helps maintain consistent air circulation throughout my home. This means my air stays cleaner and humidity levels are better controlled, creating a more comfortable living environment. I noticed that with blower activation on, allergens and dust don’t settle as much, which made a big difference for my family’s health.

On the other hand, turning the blower activation off can save energy because the fan only runs when the heating or cooling system is active. I found this useful during times when I didn’t need constant air circulation, like in milder weather or when I wanted to reduce electricity use. However, I also realized that with the blower off, air quality could sometimes drop since the air isn’t moving as much, and humidity control isn’t as consistent.

In short, having blower activation on or off depends on what I prioritize—comfort and air quality or energy savings. For me, keeping it on strikes the best balance, especially during allergy season or extreme weather, but I adjust it based on

My Buying Guides on Should Blower Activation Be On Or Off On Aprilaire

When I first installed my Aprilaire whole-home humidifier, I was faced with the question: Should the blower activation be set to ON or OFF? After some research and personal experience, I want to share what I learned to help you make the best choice for your home comfort.

Understanding Blower Activation on Aprilaire

Blower activation is a setting that controls whether the humidifier runs only when the HVAC blower is on or if it runs independently. When set to ON, the humidifier operates only when the furnace blower is running. When OFF, the humidifier can run continuously or on its own schedule.

When to Set Blower Activation to ON

I found that setting the blower activation to ON is ideal if you want your humidifier to work in sync with your HVAC system. This means the humidifier will only add moisture when warm air is circulating through your home, improving efficiency and preventing excess humidity buildup. For example:

  • If you have a forced-air heating system.
  • You want to conserve energy by humidifying only when heating is active.
  • You prefer the humidifier to be integrated with your furnace cycle.

When to Set Blower Activation to OFF

On the other hand, turning blower activation OFF can be beneficial in certain situations:

  • If you want the humidifier to run independently of the furnace blower.
  • When your HVAC blower runs infrequently, but you still want consistent humidity levels.
  • If you have a whole-house fan or other ventilation system that circulates air even when the furnace is off.

In my home, I tried this setting during mild weather when the furnace wasn’t running much, and it helped maintain comfortable humidity levels.

My Recommendation Based on Experience

From my experience, I recommend starting with blower activation ON if your furnace blower runs regularly, as it tends to be more energy-efficient and prevents over-humidifying. However, if you notice your home gets too dry when the furnace isn’t running, try switching it OFF and monitor the results. Always keep an eye on your humidity levels to avoid excess moisture, which can cause mold or damage.

Additional Tips for Optimal Humidity Control

  • Use a hygrometer to monitor indoor humidity and aim for 30-50%.
  • Adjust the humidistat on your Aprilaire unit accordingly.
  • Regularly maintain your humidifier to ensure proper function.
  • Consult your HVAC professional if unsure about your system’s blower cycles.

I hope my insights help you decide the best blower activation setting for your Aprilaire humidifier. It’s all about balancing comfort, efficiency, and your home’s unique needs!
