Why Should Blower Activation Be On or Off on Aprilaire?

From my experience using an Aprilaire system, deciding whether to turn the blower activation on or off is essential for both comfort and efficiency. When the blower activation is on, the fan runs whenever the humidifier needs to add moisture to the air, ensuring consistent humidity levels throughout my home. This helps prevent dry air issues, especially in winter, and keeps my living space comfortable.

On the other hand, turning the blower activation off can save energy because the fan only runs during heating or cooling cycles, not continuously. I noticed that if I leave it on all the time, my HVAC system works harder, which might increase my energy bills. So, balancing blower activation depends on how much humidity control I want versus how much energy I’m willing to use. Overall, understanding and adjusting this setting has made a noticeable difference in my home’s air quality and my energy consumption.

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

When I first set up my Aprilaire humidifier, one of the questions I faced was whether the blower activation should be turned on or off. This setting can impact how effectively the humidifier works and how it interacts with your HVAC system. Based on my experience and research, here’s what I learned to help you decide what’s best for your setup.

Understanding Blower Activation on Aprilaire

Blower activation controls whether the humidifier runs only when the furnace blower is on or if it operates independently. When turned on, the humidifier runs during the heating or cooling cycle, using the furnace blower to distribute moisture evenly through your home. When off, the humidifier can run continuously, regardless of the blower’s operation.

When to Turn Blower Activation On

I found that turning blower activation on is usually the best choice if:

  • You want the humidifier to run only when your HVAC system is actively circulating air.
  • You are concerned about energy efficiency and don’t want the humidifier running unnecessarily.
  • Your Aprilaire model is integrated with a forced-air furnace or air handler, ensuring moisture is delivered effectively during blower cycles.

This setting helps avoid over-humidifying and prevents moisture buildup when the blower isn’t running, which could lead to condensation or mold.

When to Turn Blower Activation Off

In some cases, I considered turning blower activation off, such as:

  • If you have a standalone humidifier system that can distribute moisture without relying on the furnace blower.
  • If your HVAC blower runs infrequently or not long enough to maintain desired humidity levels.
  • If you want continuous humidification regardless of the HVAC system’s operation.

However, running the humidifier continuously without blower help might reduce distribution efficiency and could cause moisture issues if your home isn’t ventilated properly.

Factors That Influenced My Decision

When deciding on this setting, I looked at:

  • My HVAC system type: Since I have a forced-air furnace, blower activation on made sense.
  • Energy usage concerns: Running the humidifier only with the blower helped reduce energy consumption.
  • Humidity control needs: I wanted consistent humidity without risking condensation on cold surfaces.
  • Aprilaire model recommendations: The user manual suggested blower activation on for most forced-air furnace installations.

Final Thoughts: What I Recommend

Based on my experience, I recommend keeping blower activation on if your humidifier is part of a forced-air system. It ensures efficient moisture distribution and helps protect your home from excess humidity problems. If your system or needs are unique, consult your Aprilaire manual or a HVAC professional to tailor the setting accordingly.

I hope my guide helps you make the right choice for your Aprilaire humidifier setup!
