OT – Dehumifier and Air Conditioner

[RichardJamesEsquire]

“The central AC cycling on and off is not excessive, IMHO — about the same as my AC here in San Diego.”

Yes it is excessive, otherwise you wouldn’t be complaining about the humidity.
A good residential unit will run the fan at a lower speed for a longer duration when dehumidification is needed. Variable speed fans and 2 stages of cooling capacity have made dehumidifying residential applications really easy. Your unit either isn’t set up correctly, or it’s a plain jane old school single stage single speed unit doing 80% sensible heat and 20% latent heat just like it was designed to do. Sized correctly you can see what happens with a higher latent and lower sensible heat load. Oversized in San Diego has no consequence. Throw in humidity and game over.
Get it set up right, get some control over the fan speed, or get a unit to suit the application.

I should add not only will you be comfortable with a 2 stage unit you energy usage should go down as well. The local utility may have a rebate or incentive. Not sure if the fed has a write off this year, they did last.

I have lived in Virginia, we had both, only the dehumidifier was in the basement. Mold grows quickly in a damp area, you will need at least a humidifier in the basement or lower floor in the summer so the house doesn’t smell like a mold farm…

[quote=Hatfield]dehumidifiers and air conditioners use the same underlying principle: cold air cannot hold as much moisture as warm air. [/quote]

I was thinking about this earlier.

Is there a maximum amount of moisture that a certain temperature air can hold? If so, then I’m thinking that the AC would evacuate the moisture at a faster rate when the air is warmer.

Then after a lower temperature is reached, less moisture can be extrated.

What are the physics of air and moisture? Interesting question.

Thanks for the suggestion. I’ve never had a two stage unit where the fan speed is variable.

I’ll check with the builder of the house.

Right now, I think that the AC is working fine. It’s not that I’m complaining as much as, being from San Diego, I have a lower tolerance for humid air.

I’ll see if there are settings that can be adjusted.

I just got back from NYC. It was 94 and humid on Monday. I feel your pain. Having grown up in Philly I know it all too well. Dont even think about visiting in from July 10th to July 31st unless you want to experience the worst of it.
