Ways to Reduce Humidity within Your Home

reduce humidity in your home

When you think of Phoenix AZ you think of desert, cactus, and hot temperatures. What people outside the state of Arizona don’t know is during the months of July and August, even though it’s still very hot outside, this is monsoon season. Monsoon season tends to bring more clouds which attributes to more humidity in the air. The more humid it’s outside the more humid it can be within your home.

You know it when excess home moisture raises its ugly head. You’ll spot foggy windows, smell a mildew or musty odor, you feel more sticky, or your skin feels clammy. If it’s been around for a while it had the chance to mark its territory with damp spots, mold, and rotting wood.

But even if there are no indications (yet) your home’s atmosphere is too humid it’s wise to measure and control because..

  • it will make you feel better both physically and mentally (studies show that how happy you feel is directly linked to humidity levels) and,
  • keeping more money in your pocket due to reduced heating bills is also a nice reward.

So how to reduce home humidity levels?

Often, simple measures can make a big difference. In other cases more drastic actions are necessary.

Here’s an overview of simple tips and more radical solutions on how to combat excessive indoor humidity. Easiest applicable measures are mentioned first.

Air Circulation

  • Well circulated air will dry out faster than having a stagnant air flow. Make sure that your ceiling fans are set to summer or winter rotation. Install and use bathroom and kitchen ventilation fans. Open windows to equalize the indoor and outdoor moisture levels.

Moisture Reduction

  • Using throw rugs can create a barrier between a drafty basement or hard flooring, for example. You can buy humidity monitoring data loggers from sites like Kestrel Instruments to find out how humid your house or office is. Reducing the number of plants is another method that works well. Using the hood fan on your stove will also reduce the water vapor that is being released into your living space. Dehumidifiers are available for individual rooms or the whole home, and can be installed by a professional HVAC company in Phoenix.

Make Repairs

  • Roof repairs can be annoying, but getting them done will protect your home against moisture. Replace damaged shingles, apply sealant compounds and keep your gutters clear. Weatherstrip around doors, caulk windows and any openings that lead outside the home. Seal basement walls and around the joints of walls where they meet the flooring and ceiling.


  • Especially the areas that create moisture, like the kitchen and bathroom. When vent fans are present, make sure to turn them on and/or leave them on longer. Especially in the kitchen, bathroom, and basement. If not, consider having them installed by an electrician. Finding an electrician in welshpool shouldn’t be a particularly difficult task, and you should be able to find a talented electrician who can meet your electric needs.

Cooking and Showering

  • While cooking, try to cover your food and take full advantage of the exhaust fans in which your home is equipped. Oven and stove-top cooking produce more moisture. Slow cookers contribute less to indoor humidity.
  • Take colder, shorter showers. Use a low flow shower head or shower under a less powerful stream by not fully opening the tap. (personally, I find showering with the tap partially open just as pleasant). If this requires you to have a brand new shower installed in order to achieve this, you might want to have a look at Rowville’s leading residential plumbing service to make this happen.


  • Desiccant dehumidifiers use desiccants which are substances that naturally absorb moisture (i.e. the little packets of silica gel included in electronics). Best for lower temperatures and moderate humidity. Can withstand freezing conditions as no water is produced.
  • Mechanical /Refrigerant dehumidifiers essentially work like your home’s fridge or airconditioning. Air passes across a cooled metal plate (coil) condensing the airborne moist which then drips into the water tank. Contrary to an AC these units slightly increase air temperature. Best suited for moderate to high humidity levels and moderate to warm conditions as this type of humidifier does not work well in cooler conditions.
  • Peltier dehumidifiers are usually recommended for small areas such as average size bedrooms, bathrooms, but also RVs and closets. Although they are somewhat less energy efficient these units are valued for being quiet and efficient.


  • Windows account for 1/2 of a home’s summer temperature increase. Install white mini-blinds or shutters and keep them closed when the sun is hitting the glass. These can reduce solar gain by 40% – 50%.
  • If you have curtains close them on windows that receive direct sunlight.
  • Install awnings on south facing widows if the roof overhang doesn’t block all the sunlight from reaching the windows.
  • Install sunscreens on the exterior of windows that receive direct sunlight to block sun from reaching the glass. These block as much as 60% – 80% of the sun’s heat from reaching the glass. Get a few quotes from licensed contractors, prices can vary quite a bit.
