Hey everyone! I'm looking to install a crawlspace dehumidifier and I'm planning to duct the dry air into my HVAC system. I want to use an Alorair Sentinel HDI90 dehumidifier, which I'll place in my mechanical room at the center of my house. I know some folks typically go for a whole-home dehumidifier instead of a crawlspace model, but I'm curious about any other important considerations I should keep in mind with this setup. What are the main differences between using a crawlspace dehumidifier and a whole-home dehumidifier? Any tips or advice would be greatly appreciated!

So just to clarify, you do plan on taking dry air from the crawlspace and putting it back into the supply of the HVAC, right? That’s cool! Just keep in mind that most HVAC setups usually go with a whole-home dehumidifier since they’re built for that type of environment. It might help to think about how to manage the airflow effectively to avoid creating pressure issues.
Actually, just to clear that up, it sounds like the dehumidifier will be in your conditioned space, which is great. I get why you'd lean towards the crawlspace dehumidifier to save money instead of going with the whole-home model.
