Bear with me:
I am a P&H contractor in MA ( I don't do AC) and bought a Condo type place in the West Palm Beach area a number of years ago. My wife uses it from November to April. When we bought it, folks were adamit about keeping the AC on during the summer when we weren't there to keep the humidity down. Made sense to me. So, I called a couple of HVAC guys I respect and we discussed it. The short story was they recommended controlling the humidity with the AC by using a humidistat to control the AC unit and to set the thermostat to heat to keep the unit from supercooling. The theory that the air could be hot and dry. It worked well for a few years and was cheap to run. Two years ago, the electric bills went through the roof. We spoke to the caretaker who never went near the place. She (the caretaker) finally turned the AC off. The bills went down. When we got there in November, she hadn't been in the place since the previous March when she half cleaned the place. Last year, we left the AC off. I found that the unit was low on gas and a teck added liquid. He was supposed to change the lines so we left the unit off for him. He never came to do the job. We had no problems last winter. There were no problems. A week or so, the maintenence person went in the unit because of a light and found the AC off. He lost his mind because the AC was off. We hired him as caretaker and I explained the system to him. He understood what I was saying but hadn't really heard of such thing. It was on the instructions in the Honeywell humidistat and there was something about it in the T-stat instructions.
The point being that I don't care how hot it gets in the unit, just that it be dry. When I have been there, and the system is running, it doesn't gake long for the humidity to go down because I have inside and outside sensors there to compre.
Is there any place I can find more comprehensive information on doing this?
As an aside, I see portable humidifiers installed up here in the North to try to dry out basements and the only by-product I see is heat. I did a new home for someone with a finished basement and there was water condensating on the floors because of the dewpoint/temp situation. They wanted to buy dehimidifiers. I convinced them that it would get so hot in the basement that they would open the windows to let cool, moist air in the cellar. That they needed an AC unit and a mini-split unit would be the best. I got one installed and they have lived happily ever after. I have recommended AC units many times with excellent results.
If the byproduct of a portable dehumidifier is heat, why would you want to put one in a house that you want to be cool?
Just asking for help here,
