The Benefits of Using a Dehumidifer in the Spring

Here in Florida with its subtropical climate, the average annual humidity level is a high 74 percent. The level spikes in spring and summer, because warmer air holds more moisture. If you’re seeing the effects of high indoor humidity this spring, now’s the time to learn more about the benefits of using a dehumidifier.

Why a Dehumidifier May Be Necessary

Although your HVAC draws moisture from your indoor air during the cooling process, your heat pump or air conditioner can get overwhelmed when humidity levels spike. Contending with high humidity increases your HVAC’s workload and energy consumption. It can also cancel out the cooling effect, so your indoor air stays warm and sticky. If your HVAC equipment isn’t dehumidifying your home effectively, other moisture-related issues can develop, including:

• Unchecked mold and mildew growth
• Escalating dust mite populations
• Worsened symptoms for those with asthma, allergies and respiratory conditions
• Damage to wood floors, trim and furniture
• Dank, musty odors
• Damaged carpet and padding

Basics of How Whole-Home Dehumidifiers Work

Whole-house dehumidifiers work automatically in conjunction with a home’s cooling system – all you have to do is set your desired humidity range on the humidistat dial or your HVAC thermostat. Then, the device cycles on as needed to remove the required amount of moisture:

• Humid air flowing through your HVAC system goes across the dehumidifier’s coil, which condenses the moisture it contains into water.
• Extracted water is sent outdoors through the system’s condensate drain.
• The dehumidified air is then distributed through your HVAC ductwork.

Benefits of Having a Dehumidifier

When the humidity level in your home is kept under control, you’ll enjoy greater comfort and better indoor air quality. Effective dehumidification also helps protect your home’s structure, interior finishes and contents from moisture damage. Your HVAC energy use will drop, and the equipment will last longer thanks to a lighter workload. And because drier air feels cooler, you’ll be able to save energy by raising your thermostat setting several degrees.
