Humidity In Your Home
A few Thoughts, if your home has central A/C you should not use a dehumidifier at the same time the A/C is on, Dehumidifiers put off a lot of heat which just makes the central air run more, it is probably cheaper and more effective to install a 5000 BTU A/C in a basement window and let it run, these use less power than a dehumidifier and the cooling will assist the central A/C.
You should never let the fan run all the time when the central A/C is in use if you are in a part of the country where humidity is an issue. If you leave the fan running after the compressor shuts off there is 1 or 2 quarts of water on the A coil in the air-handler, this water is quickly evaporated back into the homes air, letting the fan run all the time can raise the humidity level in the whole house nearly 5 % higher.
I often walk into clients homes and wonder why it is so humid yet cool and sure enough they are nearly always running the fan on the constant setting.
This same thing happens on window A/Cs if you leave the fan on, I would always use the energy saver setting that cycles the fan as well.
