The efficiency of whole house dehumidifiers can be trusted because of their plan of action. Removing moisture from the humid air and maintaining the ideal humidity level becomes easy with a whole house dehumidifier because of the manner of whole house dehumidifier installation. Most often, installing a whole house dehumidifier into the return air ducts is done. As a result of this, the air flowing back into the home’s heating and cooling system will first pass through the whole home dehumidifier.
Whole home dehumidifiers are designed specially to make sure the humidistat on the unit senses the rise in humid air and humidity levels. By drawing in the air into the unit to lower the airborne humidity level before the humid air reaches the cooling system and heating system, even average-sized homes can be guaranteed effective extraction of high moisture levels by using whole house dehumidifiers.
- When the unit senses a high relative humidity level or indoor humidity, the fan on the whole home dehumidifier will draw the air back in. This high airborne humidity is worked on by passing the air over a cooling coil. This is done to bring down the air temperature by making the water vapor in the air condense into liquid form. A moderate humidity level will be reached.
- The condensed water vapor is sent out to the drainage system that the whole home dehumidifier unit has.
- After removing moisture, the indoor air which is no longer humid air or warm air packed with moisture; leaves the whole house dehumidifier unit and enters into the HVAC system for further conditioning. Whether it is to change in cold air or cool air by the air conditioners or into warm air by the heaters.
- The warm air from the heater or the cool air from the air conditioners will now enter the home via the HVAC system’s blower fans.
- Apart from creating a comfortable atmosphere with the air conditioner or heater, or even the dry air that is free from moisture; the action of the whole house dehumidifier also ensures that better indoor air quality is maintained by removing the dust mites and other allergens on being treated in the air ducts.
