There is one component of indoor air quality that affects the comfort and health of occupants, preserves porous structures and possessions, helps lower heating costs, and, in a manner of speaking, it’s all relative. To properly manage indoor relative humidity in your home, proper whole-house humidifier maintenance is key.When you’re dealing with a whole-house humidifier, you’re dealing with moisture and the issues that come with it. Components must be checked for proper function and thoroughly cleaned. The following maintenance procedures should be performed at least once a year by either you or a reliable HVAC professional.

• The media panel is removed, inspected and cleaned (or replaced if needed). Mineral deposits and sediment buildup occur annually, and, over time, rust and corrosion will occur. A neglected media panel reduces efficiency, which increases component wear and energy consumption.
• The intake vent and fan assembly are cleaned, if so equipped. Dirt and debris like to stick to these components.
• The solenoid valve is inspected for function proper water flow and wear.
• The drain line is inspected for wear and cleanliness. Mineral deposits accumulate inside the drain line, too, along with algae, depending on your water’s chlorine level.
• The orifice metering device is removed and cleaned. It regulates the flow of water into the distribution tray. It must be cleaned of deposits and scale.
• When the humidifier is reassembled, it’s important that the water panel is replaced and the distribution tray is level. Otherwise, water will not flow evenly over the water panel, which reduces efficiency.

Operating tips

Optimal relative humidity levels are between 40 and 55 percent when outdoor temperature is above 40F. As the temperature gets colder outdoors, the less the humidity the home can hold without condensation forming on the windows and inside the walls. Maintaining relative humidity according to the outdoor temperature is a sure way to prevent over or under humidifying the home and its contents. Dry-air damage to household furnishings, building structure and other porous materials such as cabinetry and musical instruments is a common symptom of low relative humidity. In addition, occupants who suffer from dry skin, sore throat, dehydration, fatigue and other symptoms related to dry air will appreciate the benefits of a properly humidified home.

Properly humidified indoor air feels warmer than dry air, even when the temperatures are the same. If you maintain optimal relative humidity, you may feel comfortable lowering the thermostat a few degrees, which lowers your heating costs.
