Crawl Space Dehumidifier

Selecting the correct size is very important to the performance and life span of the dehumidifier. 

Crawl space dehumidifiers come in many sizes depending on your homes needs. Selecting the correct dehumidifier depends on the volume of air in your crawl space. Bigger is not better! When a dehumidifier is too big for the space the on board controls will work against the productivity of the dehumidifier. One of the byproducts of running a crawl space dehumidifier is heat. Heat is not a bad thing when it is winter, but it is not a good thing when you are removing moisture from the air with a dehumidifier. Relative humidity is affected by two things; air temperate and dew point temperature. When the dehumidifier gives off excess heat, that heat will lower the relative humidity and turn the dehumidifier off. Larger than needed dehumidifiers in a crawl space will create that excess heat and cause the dehumidifier to run short cycles...eventually shortening the life of the dehumidifier. Properly sizing a dehumidifier for your crawl space will ensure you get the lifespan you expect. If you need help with sizing your crawl space dehumidifier, please give us a call.
