HVAC For Beginners

Humidifier Ratings

With our humidifier ratings, you can compare whole house humidifier units side by side using our Head To Head tool.

You can compare over 50 models from 17 brands in 5 categories which are capacity, cost, warranty, availability, and type of humidifier.

You can also read the individual reviews of each brand below.

Our simple rating system gives each brand a color code and a star rating. If the card is green, then, that is one of the top picks from HvacRepairGuy. If the card is yellow, then, that would be a budget pick from HvacRepairGuy. If the card is red, then, the brand is not recommended by HvacRepairGuy. It truly is like you were taking a repairman shopping with you!

These humidifier reviews are for units that are integrated into a home's air duct system and put moisture into the air without producing steam. These are usually used on gas, oil, or electric furnace systems. For heat pump systems or very large houses, you will want a steam humidifier.

If you do not have a forced air heating system, you will want to use our ratings of portable units.
