Why Should Blower Activation Be On or Off on Aprilaire?
From my experience, deciding whether to have the blower activation on or off on my Aprilaire system is crucial for both comfort and efficiency. When the blower activation is on, the fan runs continuously or in sync with the humidifier, which helps evenly distribute the moisture throughout my home. This means the humidity levels stay more consistent, preventing dry air that can cause discomfort, especially during winter months.
On the other hand, turning the blower activation off can save energy because the fan only runs when heating or cooling is needed. However, I noticed that this sometimes leads to uneven humidity distribution, with some rooms feeling dry while others are fine. So, keeping the blower activation on ensures better air circulation and more balanced humidity, which in my opinion, makes the air feel fresher and more comfortable overall. Ultimately, it depends on your priorities—energy savings or consistent humidity—but for me, having it on is worth the comfort boost.
My Buying Guides on Should Blower Activation Be On Or Off On Aprilaire
When I first installed my Aprilaire whole-home humidifier, one of the questions I faced was whether the blower activation should be set to “On” or “Off.” This setting can impact how effectively your humidifier works and how comfortable your home feels. Let me share my experience and insights to help you decide what’s best for your situation.
Understanding Blower Activation on Aprilaire
Blower activation refers to whether the humidifier’s fan (blower) runs only when the furnace blower is on or if it has its own separate blower that runs continuously. On many Aprilaire models, you can choose to have the humidifier activate only during heating cycles (blower activation off) or run anytime the furnace blower runs (blower activation on).
What Happens When Blower Activation Is On?
When I set blower activation to “On,” the humidifier operated anytime the furnace blower was running, including during the cooling cycle or when the fan was manually set to “On.” This means the humidifier adds moisture more consistently, which can be great if your home tends to dry out even when the heat isn’t running.
Pros I noticed:
- More consistent humidity levels throughout the day.
- Useful if you run your fan continuously or during air conditioning.
- Helps maintain comfort even when heating is off.
Cons I faced:
- Slightly higher energy use since the humidifier runs more frequently.
- Potential for over-humidifying if not monitored carefully.
What Happens When Blower Activation Is Off?
With blower activation “Off,” the humidifier only runs during heating cycles, meaning it operates when the furnace blower is running to heat your home. I found this setting to be more energy-efficient and straightforward.
Pros of this setting:
- Humidifier only runs when heating, saving energy.
- Less risk of over-humidifying during warmer months.
- Simpler control based on your heating system’s operation.
Cons I noticed:
- Humidity levels can drop when the heating system is off.
- May not be ideal if you want humidity year-round, especially in dry climates.
My Recommendation Based on Experience
If you live in a climate with dry air year-round or if you use your furnace blower fan continuously for air circulation, I found setting blower activation to “On” beneficial. It keeps the humidity consistent and comfortable.
However, if you primarily need humidification during the heating season and want to conserve energy, setting blower activation to “Off” worked well for me. It’s simpler and prevents unnecessary operation.
Additional Tips I Learned
- Always monitor your indoor humidity levels to avoid excess moisture, which can cause mold.
- Use a hygrometer to track humidity and adjust settings accordingly.
- Consider your home’s specific needs, including climate, HVAC usage, and personal comfort preferences.
Final Thoughts
Choosing whether blower activation should be on or off for your Aprilaire humidifier depends on your lifestyle and climate. By understanding how each setting affects operation, I was able to tailor my humidifier’s performance to suit my home’s needs. I encourage you to try both settings if possible and see which one feels right for you.
