Help, my a/c unit isn't pulling the humidity out of my home!!?

Question

We used to have a really old split unit (part inside the home and part on the back porch) that worked great but was really old and loud. We spent thousands and upgraded seers and tonnage (we are planning on adding on) got a single unit put on the roof. Now every time monsoon season hits our home is muggy and humid, the opened food in the cupboards gets stale/soggy, and the doors warp and won't shut easily. This never happened with my old 1960's unit! I've called the company that installed it and they have tried everything they can think of and have no idea why this is happening. We hired a plumber to be sure it wasn't a water issue. It always goes away and then everything is back to normal again once monsoon season is over. But, should that matter? Shouldn't the a/c unit still pull the humidity out of my home? Why did the old unit do that but not the new upgraded one? I'm tired of being sticky and throwing away food for 2 months out of every year. HELP! Tired of being sticky

Answer 1

one of the problems with humidity in homes today is the ac tonnage is to big, yes that right,the unit don't run long enough to take out the humidity in the air,you should have one ton for each 500 sq. ft of living space,if you less than that your going to have humidity problems.hope that helps.

Answer 2

tell your a/c company to check the speed of air flow thru the house it might be too high.Medium speed setting is recomended for removing humidity.

Answer 3

It sounds like you live in an area where humidity is a problem during certain times of the year.

You have to remember that there have been a lot of changes made in appliances since the 1960's and today's appliances are supposed to be energy efficient and eco-star compliant.

While AC's are good at pulling much of the humidity out of your home window units are not as efficient as central units.

My suggestion would be to go out and purchase a de-humidifier.
