What Is the Proper Indoor Humidity Level for Your Home?

What Is the Proper Indoor Humidity Level for Your Home?

If there is one thing that the Sunshine State has plenty of – other than sunshine – it is unrelenting humidity. Florida residents often find themselves in a battle to keep their homes, not only cool, but also free of excessive moisture. When it is too humid in your home, it certainly makes it uncomfortable; however, that is only the tip of the iceberg when it comes to the troubles humidity can cause. Here is everything you need to know about indoor humidity and your home.

Ideal Humidity Level for Florida Homes

The ideal humidity level for Florida homes to keep them comfortable should be between 45 and 55%. This can be challenging, especially on hot, sticky days when the outdoor humidity is over 90%. You also want to make sure that your humidity level is not too low either because that too can cause problems—including dry skin, respiratory issues, and an increased risk of static electricity in your home.

Typically, humidity levels are measured by a hygrometer. If you have a hygrometer, you can take it into different areas of your home and see that humidity may vary from room to room. The most humid areas in your home are likely your bathroom, laundry room, kitchen, and garage. Most modern smart thermostats can also measure the humidity in your home.

What Happens When Humidity Levels Are Too High

You already know that high humidity is a less-than-ideal situation for your home because it leaves you with that unpleasant sticky feeling. Any sweat on your skin cannot evaporate because there is already too much water in the air. However there are problems much more menacing than mild discomfort that await when your home is prone to chronic excess indoor humidity:

  1. Mold and mildew. A high-humidity home is susceptible to mold and mildew. They thrive in hot, sticky environments. These can potentially threaten the structural humidity of your home, leading to expensive repairs.
  2. Health problems. Humidity and mold and mildew growth can take a toll on your home’s air quality and cause health issues like congestion or coughing. People who are more sensitive to mold may experience respiratory infections or allergy problems. It can also cause asthma symptoms to worsen.
  3. Increased indoor air pollutants. Some building materials react with high humidity and those reactions can produce harmful pollutants, for instance, when building materials like pressed wood or foam insulation off-gas formaldehyde. Furthermore, dust mites also thrive in high humidity environments. If you have a pet, the level of dust mites essentially triples.
  4. Higher bills. When it is humid, you perceive temperatures to be higher than they are. For example, your thermostat may read 75, but you may feel like it’s closer to 80. This will, in turn, cause you to blast your AC at lower temperatures for longer in order to get comfortable. This will cause your energy bills to skyrocket.

Dehumidifying Your Home

There are multiple ways to deal with excess moisture in your home. One trick is using fans to keep the air moving in your home. This helps dry out moisture and keep you and your family more comfortable. Running your exhaust fans in the bathroom or kitchen when showering or cooking can help remove water vapor and steam from the air. Taking shorter, cooler showers can help too.

Did you know that your HVAC system plays a big part in moisture control in your home? Your heat pump or central air conditioner removes a great deal of moisture from the air. Therefore, it is important to keep your HVAC equipment well-maintained so that it can do its job efficiently and effectively. However, if your current HVAC equipment is not doing its job of controlling your home’s humidity level, it is time to call in a professional and consider having a dehumidifier installed.

In the Jacksonville area, Snyder Heating and Air Conditioning is the HVAC company to trust with your home’s humidity issues.

Customer Reviews

This was an exceptional experience! We woke up to our A/C on but not cooling (it was 6am and already 81 in the house). The person who set up our appointment was very nice, able to get us seen same-day, and let us know of some options to help save us money.

-Christy Cormier

The service from Sam and Chris was excellent! They were very knowledgeable and professional. They were able to answer all of my questions and completed all of my electrical issues. I will definitely use them again for future jobs. Thank you!

-Adrienne Beal

From the get go I could tell that the Snyder employees were truly professionals and didn’t push to make sales like other companies I’ve talked to my whole life. They took the time to explain so that I could make a decision. The installers and later the duct cleaners were very respectful during their work here. Thank you.

-Mike Daniels

Snyder Heating and AC is dependable, always on time and techs have always been courteous and knowledgeable. Emanuel was a great addition to the company. He was friendly and knew what he was doing. Thank you for great service.

Snyder came in and did a total overhaul of our duct system. They had a great knowledge of what to do to make our home so comfortable! The technicians were all so professional and took great care of us! We’re so thankful for their expertise. Great and easy communication with the call center. We will definitely use them again!

-Crystal Hill

Snyder provided an amazing experience from start to finish. Most of us dread getting estimates with pressuring salespeople. Erik was a great guy, explained all my options and didn’t try to pressure me to act quickly! Justin followed up with my husband and I to offer further assistance in our decision. Again, no pressure, just helped with our follow up questions.

Snyder was easy to get in contact with and had availability the next day. Clint came out and needed some parts so had to reschedule us for the next day for installation.
