Humidifiers vs. Dehumidifiers – What’s the Reason for Each

Posted on AC Tips June 5, 2019

In our industry, the term “comfort system” often takes the place of “air conditioning” or “HVAC system.” This is an appropriate term, as the main purpose of your HVAC appliances is to keep you and your family comfortable all year round. Sometimes, comfort extends beyond just too hot or too cold; factors like indoor humidity can also have a big influence on your comfort level.

When a homeowner is in a Goldilocks-type situation where it’s too moist or too dry in their home, they turn to humidifiers and dehumidifiers to make it feel just right. There’s a variety of reasons why people turn to either, usually to address health, cleanliness, or comfort issues. To get a better idea of the purpose of each, we’ll tackle each appliance one-by-one.

When dry air conditions are common to your area, humidifiers are there to the rescue! Indoor humidity refers to the amount of water vapor that is present in your home’s air, so a humidifier’s function is to add that water vapor. While the climate tends to remain humid in Vero Beach FL, humidifiers can still help serve a variety of purposes.

If you’re prone to becoming sick, moisture in the air can help reduce the spread of illness as well as boost your recovery time. Bacteria and viruses have a tougher time spreading in humid air, and humidifiers are often used to alleviate people experiencing sore throats, runny noses, or coughing. Humidifiers are also great for keeping skin feeling soft and moist as well as keeping indoor plants healthy!

In Florida, humidity tends to plummet in November all the way through late February. Consider investing in a humidifier to make up for that lost moisture and keep your home comfortable!


As you may have imagined, a dehumidifier serves the opposite function of its moisture-bringing counterpart. A home that feels too damp can benefit from these appliances. A dehumidifier does not remove all moisture from a home, but rather brings the level of moisture down to an optimum level for comfort. This comes in handy for Florida weather, where humidity is often a given!

Whenever it feels “stuffy” in a room, it can often be attributed to excess moisture. Humidity can often rush into your home when you open your doors or windows. Florida is known for it’s near-tropical weather and frequent rain, so a dehumidifier can make quite the difference.

Dehumidifiers are great for improving the air quality of your home, as lower humidity levels can eliminate unpleasant odors and alleviate symptoms related to allergies. Mold and mildew are two threats to rooms that often get damp – like bathrooms and basements. By adding a dehumidifier, you can decrease the likelihood of a mold or mildew problem. Lastly, by removing excess humidity, you can make your home feel cooler. This can help with your energy bills, as you won’t feel the need to crank your thermostat down when it feels too stuffy!
