Crawlspace Waterproofing – Is Your New AC Unit Making Your Crawlspace Damp?

No time of the year is quite as fun as the summer. The warm weather and long days mean more opportunities for outdoor fun. However, when the heat is too much, it’s a great relief to be able to turn the air conditioner on and stay cool indoors. If you live in a home that was built over 20 years ago, there’s a good chance that you have had to replace the old AC with a newer and more efficient model. While this is great for your energy bills and for maintaining a comfortable interior environment, it can mean trouble for your crawlspace.


Your AC May Be Making Your Crawlspace Damp

If you have invested in a new AC, it is important to pay close attention to crawlspace waterproofing during the installation of the unit. It is well-known fact that more than the conditions in the living space affect the crawlspace. Air moves from the living space above to the crawlspace below. When you have a more efficient AC the cold air from the living space above will move into the crawlspace below. This air will carry moisture along with it. This will result in increased humidity in the crawlspace.

Many people that replace their AC units do so without replacing the ductwork. While they may upgrade their HVAC units, they may want to save money by avoiding the replacement of ductwork. Some may avoid replacing the ductwork because it is still in good shape. It is important to note that ductwork that was installed more than 20 years ago will likely have a different R-value of insulation compared to that installed in modern homes. The insulation may not be effective at creating a good thermal barrier between the warmer crawlspace and the cold air in the HVAC system. Moisture droplets are likely to form in the crawlspace as a result of warm humid air coming into contact with the cold ducts.


Crawlspace Waterproofing To Keep Your Crawlspace Dry

If you have installed a new AC, you must pay attention to crawlspace waterproofing. You should not only ensure that the crawlspace is encapsulated but also has a dehumidifier installed within it to remove excess moisture in the air within the crawlspace. Discuss your needs with a professional to ensure the best results.
