If there is NO insulation in that ceiling (which is unlikely), then you could get a benefit from the foil, even though the drywall is there. However, the foil really needs to be closest to the outside in order for you to see a real benefit from it as a summertime heat blocker. Yes, we have had cases where customers did an install similar to this (attaching wooden strips over the existing drywall, stapling foil to the wood and then adding a new layer of drywall over it). Then, if the humidity is too high, install a plug in dehumidifier. The adjust the flow of refrigerant based on the 'load.' An inverter system will run longer but pull less amps resulting in more dehumidification, lower energy bills and less of a 'muggy' feeling in the home.įor you particular situation, I would install a radiant barrier. Inverter type air conditioners are similar to a cruise control on a car. These systems are made by companies like: Mitsubishi, Daikin, LG, Sanyo, Fujitsu and many more.

Personally, I like to use air conditioners that use 'inverter' systems. Or, you can install a two stage (high & low capacity) air conditioner. The easiest method is to install a dehumidifier to pull out extra moisture. If your air conditioner is 'short cycling' then you have a couple of options. However, anything you do to drop the load more (including installing radiant barrier) can cause most systems to be even MORE oversized (the difference between what it can do and what you need it to do becomes a big difference), which could result in a lack of dehumidification but this really depends on you climate area. So, in reality, most systems are oversized 98% of the time. In fact, we tend to size our AC systems to handle 'full load' (which is usually the hottest day of the summer) however, we are usually only at full load' about 2% of the time.

The fact is that MOST air conditioning systems are oversized.
