Furnace Humidifier Requires Annual Maintenance

Furnace Humidifier Maintenance: Breathe Easier, Live Better

A whole-house humidifier is an important part of your HVAC system, especially during the dry winter months. It’s not just about comfort—it’s about health! Proper humidity levels can reduce static electricity, prevent wood from cracking, and, most importantly, help soothe dry sinuses, throats, and skin, making you less susceptible to illness.

To keep your unit running at its best, regular cleaning and maintenance are essential. Mineral deposits and scale buildup are the enemy, reducing performance and potentially leading to costly leaks.

Your Annual Whole-House Humidifier Checklist

While your specific owner’s manual (like those from Aprilaire or Honeywell) is the ultimate guide, these general rule-of-thumb guidelines will cover the key maintenance steps for most bypass or fan-powered models.

Before you begin: Safety first! Turn off the humidifier’s water supply, unplug the unit, and turn off the electrical source to the furnace. Then, remove the humidifier cover.

Water Panel (Evaporator Pad) Replacement:

Remove the water panel from its frame.
Replace the water panel annually to eliminate mineral buildup, which is the primary cause of poor performance.
Clean the water distribution tray (located on the top of the frame) to remove any scale or mineral deposits around the holes. If it doesn’t come clean, replace the tray.
Reassemble the frame and reinsert it.

Inspect for Leaks and Cracks:

Squeeze the water feed tube between your fingers and check for any cracks. Replace old tubingimmediately to prevent expensive water damage.
Check for leaks or potential leaks around all connections.

Clean Components:

Remove the strainer and flush it thoroughly under running water to clear scale and mineral deposits.
Remove the orifice (the small fitting at the end of the water feed tube) and run it under water to remove mineral deposits and ensure it isn’t clogging the water feed.
Check the drain line for any blockage or standing water.
