Can a mini-split dehumidify?

[@wcbscout]

Before I watch any of this, yes of course, a cold coil will dehumidify

[@PioneerBuildersInc]

You're correct. This is more specifically in relation to a VRF system

[@janetshaffer423]

I really like your ladder.

[@PioneerBuildersInc]

Me too 🙂

[@cesarjavierbarbosa2acidgre276]

I have mini split that has the following modes: Auto, Cool, Dry, Heat, Fan But I also have a dedicated compressor refrigerant based dehumidifier. I live near the gulf coast and is humid in most of Spring, Summer, and early fall.

[@PioneerBuildersInc]

Without knowing the dehum model, that is likely the best, most efficient way to go. 👍👍

@@PioneerBuildersInc Dry mode works but only brings 30% humidity down.

[@Gopher7]

Dry mode has nothing to do with your plugged condensate drain. You pull even more humidity in cool mode. The object of dry mode is to dehumidify without turning the conditioned space into a refrigerator.

[@PioneerBuildersInc]

@@Gopher7 dry mode will result in a higher flow of condensate. If a drain isn't fully obstructed, the amount of condensate in AC mode may be low enough to drain through the line, but a higher flow rate may not be able to drain.

[@brianm4789]

can you program the unit to automatically run dry mode say for example 1-2 hours a day, and resume heating/cooling the other times ?

[@PioneerBuildersInc]

Unfortunately, no, at least as far as I know

[@dplj4428]

I’ve read that some air conditioners start to falter if space tends constantly up around 80% humidity. In those homes is it useful to occasionally have a dedicated dehumidifier?

[@PioneerBuildersInc]

I can't speak to the equipment response to 80 percent rh (I assume there is a high air temperature too). Having a dedicated dehumidifier is the best situation for that. Check out Santa Fe or Aprilaire

[@antoniomartinezmd5473]

Is Puerto Rico, Caribbean zone a high humidity zone? Thank you.

[@PioneerBuildersInc]

It sure is

[@wjthehomebuilder]

Interestingly, I was comparing the H2i (Hyper heat) Mitsubishi unit vs the regular one and the hyper heat stated "0 pints/ hr" under moisture removal. The standard one was like 0.4 pints/ hr (which was the one I picked specifically for moisture removal.) I'm not sure what's up with that.... Side note, We have the same picture centered over our bed as well.

[@PioneerBuildersInc]

Super interesting... And, as they say, birds of a feather... 🙂

[@wjthehomebuilder]

@@PioneerBuildersInc ..... build air tight together? 😆

[@number1pappy]

​@wjthehomebuilder interestingly enough here in South Carolina because of mold issues in a majority of all the new constructed air tight homes. They have to have outside air inlets ,air exchange units and whole house dehumidifiers retrofitted because they are so air tight! The irony of this is just laughable.

[@wjthehomebuilder]

@@number1pappy Make up air is a must on tight homes. 👍

[@jdreynolds29]

I'm an HVAC tech since 1999 in Houston and for what you just said there's a lot of problems but that is maybe only climate and location specific.... I'm not going to address any of that I want to know what pants are you wearing in this video because they look like lightweight and stretchy yet durable pants and that is exactly what I'm looking for right now

[@PioneerBuildersInc]

I think those are the Cloud pants from Truewerk. You might check out their T1, T2, or T3 as they all have different characteristics.

[@jdreynolds29]

Thanks 👍

Would you use it to dehumidify the home during winter?

[@PioneerBuildersInc]

Generally, the air is drier in winter, so you wouldn't need to dehumidify

[@dawsonparnell4934]

What about if the air was more humid and the average temperatures were a high of 8 C and a low of 2 C. Would you use this method?

[@PioneerBuildersInc]

@@dawsonparnell4934 would the equipment be in heating or cooling?

[@KidKallum]

[@PioneerBuildersInc]

@@KidKallum unless you have an indoor hot tub, homes typically don't need dehumidification in winter

[@number1pappy]

Ok seriously you dont have a humidity issue if you have to run the water in your house with your exhaust fan off to raise the humidity! I think its also fully known a mini split while it will reduce the humidity. It wont do it as effectively as a dedicated dehumidifier. Thanks anyways 😊
