What to Do About Excessive Indoor Humidity

What to Do About Excessive Indoor Humidity

Humidity is something Texans are no stranger to, especially during summer months. However, while there may not be much you can do about the humidity levels outside, excessive levels of humidity inside your home can actually be a problem. Humidity can cause a number of issues, including causing mold growth, preventing proper drying of things like clothes and towels, and even preventing you from finding cool, comfort and relief from the sweltering outside temperatures.

When you’re dealing with excessive indoor humidity, it’s easy to become frustrated as it’s not always a simple problem to solve. However, if you know what to do and what may be causing your excessive indoor humidity, you can target the source and find an effective way of dealing with it. On this blog, we’ll take a closer look at how to deal with elevated indoor humidity levels effectively.

Stop Air Leaks

Excessive indoor humidity has a number of causes. In some cases, things like a plumbing leak can continually supply the air with moisture that evaporates and increases humidity levels. However, the most common cause of excessive humidity is air leaks which allow humid air from outside to replace cool, dry air from inside your home. Stopping these air leaks can not only keep indoor humidity in check, but even save you money on your utility bills by allowing your home to stay cooler while using less energy.

There are three big places you should check for air leaks in your home:

  • Around doors and windows: Your doors and windows are surrounded by a plastic or rubber seal known as weather stripping. This material is intended to be flexible so it can create a firm seal and prevent air leaks, but over time exposure to the elements will cause it to wear out and need replaced. You should check your weather stripping every six months or so, and replace it every two years or so, as cracks and wear start to show.
  • Holes in your ceiling: Heat naturally rises, and holes in your ceiling are prime targets for warm air to seep into your home. Anything that’s installed into your ceiling can be a hole where air can leak through, including recessed lighting, ceiling fan installations, chandeliers, and much more. These areas need special insulation around them, which is usually installed from your attic.
  • Your attic: Your attic gets particularly hot and humid during summer months, which is why it’s pivotal to have outstanding ventilation, and good insulation between your attic and the rest of your home down below.

Use Your Air Conditioner to Your Advantage

Your air conditioner is perhaps your best ally against indoor humidity because the air conditioner cycle naturally removes humidity from the air. The cold refrigerant in your evaporator coil (located in your indoor unit) causes the metal coil’s surface to also become extremely cold. As air passes over the cold coil, the vapor drops in temperature, which causes the vapor to condense into liquid water. It’s like if you leave a glass of ice water on your kitchen counter for about 20 minutes or so: when you come back to it, the outside of the glass will probably be foggy, clouded, and possibly even covered in water droplets.

This is why it’s pivotal you have a drain pan that’s in good condition installed beneath your indoor unit: your air conditioner will naturally remove the humidity from the air and turn it into liquid water, which needs a place it can drip down to and eventually drain away from.

Use a De-Humidifier

If your air conditioner can’t keep up with your excessive indoor humidity problem, then you may want to consider using a de-humidifier in your home. De-humidifiers come in a range of shapes, sizes, and capacities, and you should talk to a skilled Kerrville air conditioning expert about your issue before making this investment. Small units may be good for handling humidity in a single room, but whole-home solutions may require a little bit more work and will be more expensive.
