Is there a maximum amount that your air conditioner will cool your house?

Question

Assume it's 100 degrees farenheit outside. If you set your a/c to 50 degrees, would it actually cool to that point or is there a formula and limiting factors. Where can this be found?

Answer 1

Without all the hipe, simple answer.

A super good designed system will hold your home around 70 deg.

A fairly inexpensive will stay within 15 - 20 degrees of outside temp when the outside temp. goes above 95.

We have sold systems that can do 60 no matter what the outside temp., but this is no longer a common residential system. Big $$$$$.

Answer 2

“Cooling capacity
Manufacturers produce air conditioners in a variety of sizes,
typically measured in "tons" or "BTUs per hour." A BTU (British
Thermal Unit) is a common unit used for measuring heat output, equal
to the amount of energy required to raise one pound of water one
degree Fahrenheit. One ton equals 12,000 BTUs/hour-a term derived from
the amount of energy required to melt 1 ton of ice in a day.

With air conditioners, bigger is not necessarily better. For one
thing, the larger the capacity, the more a unit will cost; output is
directly related to cost. Also, it's critically important to pick a
size that is appropriate for the house. An air conditioner that is too
small can't keep up with load requirements on a particularly hot day.
One that is too large will cycle off and on too frequently, doing a
poor job of dehumidifying the air, which degrades comfort. In fact,
it's better to slightly undersize an air conditioner than to oversize
it. Also, the air flow into and out of rooms must be carefully
balanced to insure efficient operation of the system. These factors,
as well how well a house is insulated, how it's used by your family,
the climate and more must be taken into account when selecting and
designing your system. That's why you should consult a qualified air
conditioning contractor.”

Answer 3

most a/c units are only designed to operate 20 degrees cooler than the outside ambient temp.

Go call an A/C repair technican and ask.....call 5 of them at different companies.

Answer 4

typically a system will cool 10 to 15 degrees F lower than the outside temp

any more is lucky

Answer 5

Air condition is sized according to constant heat load with a dry bulb temperature (Thermometer) of 72 degrees and wet bulb temperature (Humidity) of 68 Degrees ,but is different in every state according to states normal temp, humidity,and elevation.

Answer 6

Actually, my husband would like to know that, if you find out! Where he works, the AC will NOT shut off, at all, even when you put the switch in the OFF position and yesterday it was down to 55 in the office. He has to open the windows to make it bareable to work! LOL!! So I think it will go until the AC freezes up.

Answer 7

look at the BTUs, the amount of Cubic feet in your house and figure it out from there
