We have a portable dehumidifier just in case we ever experience that complication, but honestly the A/C system works just fine to prevent that type of problem
One of the things I love most about the house we chose to buy is the huge amount of space there is. There is a massive floor plan with 9 bedrooms and 5 bathrooms. At one point in time, this place was an assisted living care facility, but it has been converted into a beautiful single family home with an in-law suite. I basically have it set up so there are plenty of guest rooms for when I have friends and family come out. This way everybody can be perfectly accommodated and have their privacy at the same time if they wish to stay over. All the guest bedrooms not only have their own bathrooms but they also have their own zone with a ductless mini split system. The ductless mini split system has a total of 8 zones which do a phenomenal job of heating and cooling the home. The amazing thing is that we don’t have to make the areas we are not using comfortable. We just use the A/C very slightly in the guest rooms merely to keep humidity out of the air. We never want to deal with too much humidity in any section of the house because the last thing we want is mold and mildew complications. We have a portable dehumidifier just in case we ever experience that complication, but honestly the A/C system works just fine to prevent that type of problem. I really must say, I was skeptical about having huge energy savings with the ductless mini split, but the savings have spoken for themselves. We love our ductless mini split HVAC system.
