Excessive moisture within a home and can be a terrible thing for your air quality among many other things.
It’s especially bad if your house is primarily constructed of wood and you have a lot of wooden furniture.
Excessive moisture can cause the wood to rot and warp, and it can also cause mold and mildew to grow. God forbid your air conditioner is too large for your house, because that will also mean that it will turn off and on too quickly, which does not give the system enough time to eliminate the humidity from the air! Also, if your roof tends to leak in certain spots, you’re in even worse trouble! You’ll end up with a cool, damp, musty house where mold and mildew can run rampant and wreak havoc on your respiratory system! You got to keep the moisture level in your home under control! Find and eliminate leaks. Properly size your air conditioning unit for your home, so that it does a better job of eliminating humidity. If you feel that it is necessary, get your hands on a dehumidifier as well! Sometimes, not even the air conditioner unit can remove enough humidity from the home, so a dehumidifier will serve you well, especially if you live in climates that have excessive heat and humidity. With all of this more less under control, you may also want to invest in an air purification system. Make sure your air ducts are cleaned out by a professional, and your air filter is fresh and new before you even bother with the air purification system though!
