I have a new central air conditioner. Normally, it cools down the house 5 min per degree, so it takes around 25 min to lower the temperature from 80 to 75 degrees upstairs. I have 2 floors. Today, I went out to run errands and didn't get back until 1pm, when it became 91 degrees outside and 85 degrees inside. I kept the AC on for several hours, and it didn't cool the house below 78 degrees until 9pm.
Does the AC work less effectively when it's really hot outside, and the coils don't cool off very fast in 90 degree heat? Is that why it didn't go below 78 degrees inside till night time?
Is there such as thing as a super-hot day when even a 3.5 ton AC gets overwhelmed? Is there any point to "staying ahead" by turning the AC on at 11am if we think a hot one is coming in order to start cooling earlier before the house gets really hot?
