System sizing is also very important. At undersized system will not keep the house cool. An over sized system will cool the house down before the moisture is removed and make the house feel clammy. Window sizes and direction into the sun, room size, floor and attic insulation, all affect sizing.
Our designers do not use rule of thumb equipment sizing. All of our installation are sized using computerized data from specially designed software. The result is a system closely matched to your home. Rule of thumb sizing often results in oversized units with unbalanced distribution.
