Dehumidifier & Ac


I have a question about haveing a dehumidifier and also haveing a AC going at the same time.

About 15 years ago I was talking to a contrector about have a whole house dehumidier and also putting a AC in my house. They told me that by haveing a dehumidifier would cut down on the work of the AC and make it better on cooling the house off.

What do you think or feel about how this would work?

Would it be better to do it this way? Or is it better to just have the AC do the work?

I have Dehumidifier that I can install into my Furnace for the whole house, can I install it also into my AC?

Is it beneficial to have them both run at the same time?

Will it make it easyer on the AC?

I need help and you have answers.

Re: Dehumidifier & Ac


Drying out your house with a dehumidifier will make the air more comfortable to you. But, it won't change the actual temperature on the thermostat so the a/c will still run just as long to get to the set point. The a/c unit runs to make temp it doesn't run to control humidity, that is just a side benefit. But, you may feel better in the dryer air and set the t-stat a little higher causing the a/c to run less.

Question on the Dehumidifier during the Winter Months, do you turn this off because in the Winter months I have my Humidifier going?

How do we work around this?

Also I need a Hygrometer Any suggestions on a good one? Like to have all tree instruments on one board.

Never use the dehumidifier in the winter, you want to humidify in the winter as the air will feel more comfortable.

The little ''weather stations" are in no way accurate. Look into a Fluke or Amprobe hand held hygrometer.
