As we approach summer, we want to remind everyone that there is a limit to how many degrees an air conditioner can realistically cool when comparing temperature differences between inside and outside air.
Generally speaking, an air conditioning system is designed to accommodate up to a 20 degree difference between the outside air and inside air while still keeping around a 55% humidity level, which is comfortable. This means that it is 80 outside your AC can easily reach 70 degrees, since that is only a 10 degree temperature difference. So even if it is 90 degrees out your air conditioner should still easily reach the 70 degree mark. However, if it is 100 degrees outside, it will be nearly impossible to reach 70 degrees inside without the air conditioner working completely overtime and causing problems such as excess humidity.
When we have these high-heat Texas days it's important to try to not overwork your AC unit. Things like keeping the blinds closed and using fans will help cool the room down, save you money on your electric bill and prevent your AC unit from working too hard.
