Why doesn't my humidifier work at all?

A humidifier’s main control feature is a humidistat. If it’s not functioning properly, it won’t let your humidifier work. Other problems could include a valve, motor, or transformer. Whenever your furnace or air conditioning unit is running, your humidifier should run as well. Most humidifiers work by evaporation.

Why does my humidifier leak?

Your household water supply feeds the humidifier. Yours may have a reservoir or use a continuous flow system. Check the water connections and valves for leaks. Reservoir systems use a float ball to control the level of water in the holding tank. Make sure the float is working properly. If your humidifier is a continuous flow set-up,you want to make sure that all the hoses, valves, and tubing are connected tightly. Plastic fittings and hoses have a tendency to break down over time. You will also want to make sure that the filter and drain lines aren't clogged or kinked in any way. Due to expansion from heat, and contraction from cold, sometimes fittings become loose. Put a wrench on and snug the connections to make sure they are all tight.

Why is my humidifier so noisy?

When a humidifier is operating, it is going to make some sounds. You might hear water gurgling or sloshing around, and that's normal. You may hear the fan spinning through the air, or hear the hum from the fan motor. Even the solenoid valve makes normal sounds. There’s not a lot to do to fix this problem, unless it gets so noisy that you want to replace the parts.

Why is my house too dry?

Many new high-efficiency furnaces don’t run for long enough to evaporate enough moisture into the air. They just heat the home up too fast for a humidifier that's attached to the furnace to work properly. Some people choose to add the moisturizing power of a free standing unit to their furnace humidifier, while others may opt to set the furnace fan to run all the time. This will keep air flowing past the medium and keep evaporating water into the air.

How humid do I keep my house?

Everyone's comfort zone is different, but we all need a certain level of moisture in the air we breath. Relative humidity is the amount of water vapor that the air holds at a certain temperature, and is referred to as a percentage of the amount of water vapor the air could hold at that temperature. Rarely does the air hold 100% of the water vapor that it could. Recommended levels of humidity in the home change as the outside temperature goes up and down. If the outside temperature is -20F, 15% relative humidity in the home is okay, while an outside air temperature of +20F has a recommended relative humidity of 35%-40%.

Why is there no water going through the flow pad?

Check the water inlet valve, and any hoses or tubing for kinks. Test the water inlet valve coil for continuity. If you have a clogged valve, you may be able to clean it out. It is also possible for the humidistat to burn out.

How do I determine my humidity levels?

You can determine the humidity level by using a hygrometer. You can purchase one at almost any appliance store, home centre, or hardware store.

Should I run my humidifier all year?

In most areas, once heating season is over, you do not need to run the humidifier. However, if you have any type of breathing problem, or live in a dry area, you may want to run it for your comfort and health needs.

Should I clean my humidifier?

Yes. You should disassemble the unit periodically and clean it with household cleaners and disinfectants, or you can purchase Humidifier Bacteriostatic Treatment, which is available through our website or local stores. Always unplug the unit first.

Why doesn't the pad spin?

The water pad normally gets turned through the water reservoir by a small electric motor. Sometimes this motor can burn out. If the furnace blower is on, and the humidistat is calling for more water, and the motor doesn’t spin, it’s time to replace this motor.

What is relative humidity?

Relative humidity is the percentage of how much water vapor is in the air compared to how much water vapor could be present at that particular air temperature and pressure.

What it boils down to is this: 100% relative humidity is the maximum amount of water vapor that a certain volume of air can hold at a certain pressure and temperature. When air is warmer, it can hold more water vapor. When air gets colder, it can hold less water vapor. So, in effect, when the warm air goes past the cold coils, the air can hold less water vapor, and the excess condenses on the coils, removing it from the air and lowering the relative humidity of the air in the room or home.
