Air Conditioner Humidity Settings

Say your system moves air at around 400 cfm per ton.

Air conditioner humidity settings.

Many systems are set up to move air at a rate faster than that. Let s take a look at how this thermostat setting increases humidity and what setting you should be using instead. For humidity removal a faster rate is not ideal. Using a cool mist humidifier over summer can help increase humidity without heating up the room.

If the equipment doesn t have sufficient cooling capacity it may be unable to cope with extreme humidity. How leaving your ac fan on increases humidity. How humidity affects air conditioning. A ceiling fan or box fan causes a wind chill effect that makes you feel cooler at a higher temperature setting as long as the humidity isn t too high.

First off it s helpful to know the two settings for your ac fan and the difference between them. When humidity levels are excessive they need to work a lot harder. Air conditioners cool homes by removing heat and moisture from the air. To remove the uncomfortable humidity from the air while your air conditioner is in the cooling mode you will need to lower the thermostat a few degrees colder than you normally would.

In hot humid climates like ours you want your air conditioner to move air at a rate at or near 350 cfm per ton. Your air conditioner will not cool any faster it will cool at the same rate but will run longer until it reaches the lower temperature. As a result the home may never feel truly comfortable. Another habit to avoid when looking for the best temperature for ac settings is setting the thermostat on a colder setting to cool the home down more quickly after you ve been away.

When the unit can only run at one speed it turns on and runs full blast until the air reaches set temperature. Auto this setting runs your fan only when your ac is blowing cold air. The air conditioner will keep the temperature stable and at a comfortable level while the humidifier will help maintain the perfect level of humidity inside your home. The best tools to keeping relative humidity at ideal levels in your home year round are whole home humidifiers and dehumidifiers these systems automatically work with your home s heating and cooling systems to add or remove moisture from the air.

Maintaining ideal relative humidity levels in the home. An air conditioner that s only capable of running at one speed basically on or off can have the same problems as one that s too large when it comes to hvac humidity control. Lowering the temperature setting will cause your air conditioning unit to cool the air to below the dew point of the outside air.
