we recently had central air conditioning installed.
During the transitional period - august & sep when temperatures
fluctuate a lot in maryland, should we leave the a/c on all the time
and just adjust the thermostat and thus obtain the benefit of the
de-humidifcation, or should we turn it off and on as needed/
Set the thermostat and leave it on. You may want to change the temp day
and night for example while you are at work.
Normally it is cheaper and more comfortable to leave it on all the time.
Depending on your tolerance you may turn it off for a few days or weeks when
the outside temps are comfortable. I would not recommend turning it of and
on while opening and closing windows as that often results in less comfort
and greater cost, not to mention more pollen.
You might want to install a programmable thermostat. Set it to go or off at
certain times of day or night. Mine, for example, is set to start cooling in
the morning till our family leaves. Then it resets itself to a warmer temp
until around 4 pm when my wife and kids come home. Then it sets itself again
at bedtime. This really saves dollars on your elec. bill.
