4 Easy Ways to Prevent Humidity DamageWith warmer weather comes higher humidity. High humidity can cause severe problems, such as mold, mildew, and dust mites—all contributing to miserable seasonal allergies.

With working exhaust fans, dehumidifiers, and ventilation systems, you’ll be taking positive steps toward controlling the humidity levels in your home.

You can also consider a whole-home approach with professional installation of a whole-home humidification system directly into your HVAC. Just set the desired humidity level (somewhere between 30% and 50%) and the humidification system will add or remove moisture from the air as necessary.

If you don’t have an HVAC system that measures your indoor humidity, you can purchase a hygrometer to measure the amount of relative humidity in the home.

Signs of High Humidity in the Home:


  • Condensation on windows and HVAC equipment
  • Moisture on walls, ceilings, and fixtures
  • Peeling/flaking paint or wallpaper
  • Mold and mildew
  • Musty odors
  • Attraction of insects
  • Damaged furniture, art, books, and other property


How to Prevent Humidity Damage

If humidity and allergies are an issue in your home during the spring and summer months, learn how to prevent humidity damage with these solutions.

Speak with a professional about which option would be best for your home based on your needs. Exhaust fans to portable dehumidifiers are available for combat indoor humidity. For a solution with more longevity, consider professional whole-home humidification.

1. Turn on the Air Conditioner

Your air conditioning system actually dehumidifies the air naturally through its refrigeration cycle. As warm air passes over the cold evaporator coils, condensation is formed and drips down into the A/C drain pan. From there, the condensate leaves the home through the condensate drain lines. This is the water that was in your warm air.

Air conditioners can be used to help control indoor humidity, ventilation, and temperature. But before you turn on the air conditioner, make sure you have a clean filter. Otherwise, you may doing more harm than good.

2. Working Exhaust Fans

The advantage of exhaust fans is that they do a good job preventing moisture related problems in areas where moisture and high humidity is prevalent.

They are also economical for those on a budget. Make sure all of your exhaust fans are working and venting properly.

One potential downside is the noise. And some exhaust fans take a while to successfully remove the buildup of moisture and indoor air pollutants. If your exhaust fans are old and noisy, consider a replacement.

3. Portable Dehumidifiers

Portable dehumidifiers can be plugged in anywhere there’s an outlet. They’re easy to use and less expensive than whole-house humidification. While portable units can provide extra dehuhumidification during flooding, leaks, and other moisture problems, they aren’t a good solution for an entire house. They can only dehumidify one room at a time.

In addition to their shorter lifespans and lower energy efficiency, portable units also require frequent maintenance. You will have to dump the water out yourself and clean the unit periodically. 

4. Whole-Home Humidification 

Whole-home humidifiers and dehumidifiers are installed directly into the HVAC system. By using a built-in hygrometer to measure relative humidity levels, the machine is able to detect when humidity levels go above or below the ideal humidity range. Simply set the humidity level and forget it.

If the device senses low humidity (below 30%), it will start humidifying the air through your existing central air system. By humidifying the air that flows through your ductwork, the entire home gets properly humidified.

If your whole-home humidification system includes a dehumidifier, it will start to remove moisture from the air (by condensation) when relative humidity goes over 50%.

Whole-Home Humidification from Pacific Heating & Cooling

High humidity is bad for your home, possessions, and health. If you don’t have a whole-home humidification system that monitors the humidity level and adds or removes moisture as necessary, you may want to consider it. Learn 5 reasons you should monitor and maintain your humidity levels.

With a whole-home system, you’ll be able to set the perfect humidity level. This is especially important if you have delicate books, art, wine, and other possessions sensitive to moisture.
