Humidity! How to drop 20-30% in an hour.

This is getting way too complicated.

For the problem situations I mentioned in my earlier post (I believe about the same problem as the OP was addressing), I needed more air conditioning run time to reduce the humidity in our RV's interior air ... but it wasn't warm enough inside the RV or outside the RV to merit running the air conditioning as much as needed to get out the excess moisture in the interior air ... hence we would have been too cold (even though dryer, humidity-wise) if we had kept running only the air conditioner.

So, we just ran the propane furnace at the same time to add just enough heat to keep us comfortable while the air conditioner was running and reducing the humidity. We ran both at the same time - NOT alternating back and forth between the air conditioner and furnace. It worked simply and very well.

That is another way to do it. It's interesting to know that running both at the same time also works, though I wonder if one method is more effective/efficient than the other? I can only run one at a time- using the electric heat option.

I agree the discussion seems to have taken an unproductive (and hopefully temporary) detour, but there is merit in an expert discussion and explanation of 'why' it works, and even 'how' by a competent poster.

I think the poster attempting to explain relative humidity vs absolute humidity simply did not go into enough detail, which conveyed the wrong message.

After all, 'Heating AND Cooling' at the same time or in conjunction with each other appears to be an oxymoron and initially could cause some head scratching. A wise and educational discussion could be of interest to readers ;)

Edit to add: My A/C was running continuously before trying the heat then cool cycle, with little reduction in humidity. Although heating can allow the A/C to run more, it wasn't really the purpose in our case, though I can see that benefit, too (especially on cooler days).
