brain went blank, how to calculate the required size a/c unit ?


I know there is a formula, just don’t know the formula.

Do you mean estimated, rule-of-thumb but not-to-be-relied-on?


Down here, and in many other areas (but not all), 500-600 sq ft per ton. But that depends on many more things than just location, insulation (or lack of it) is also a big factor, as are high ceilings (more cu ft of air to cool).

Okay, okay, before I get jumped on, the a/c does NOT cool the air. It REMOVES heat.

But that results in COOLER AIR, right? So, its net effect is to cool the air. ![icon_smile.gif](upload://b6iczyK1ETUUqRUc4PAkX83GF2O.gif)

Yes, rule of thumb.


I knew I should be more specific, because I knew there would be 100 different available answers to a question so vauge. icon_biggrin.gif


I now remembered (as a rule of thumb) or generally, or historically, or most use, (insert favorte non obligatory saying here) is 500 sq. feet .


Thank you for the quick response !!!

hi to all,


up here in the frozen North we can get away with 600-700 feet per ton dependent on the house as it will only get used 3 weeks per annum anyway ![icon_wink.gif](upload://ssT9V5t45yjlgXqiFRXL04eXtqw.gif)

Gerry,


You use A/C 3 weeks per years and we use heat 2 weeks per year, that almost averages out, doesn't it? ![icon_smile.gif](upload://b6iczyK1ETUUqRUc4PAkX83GF2O.gif)

Depends, of course , on the current spot price for Natural Gas. Things are not looking good for the upcoming winter if you’re north of the Mason-Dixon line. Of course, Mr. Peck’s a pretty bright fella. Seems to me that if they’re removing all that heat from the residential air supply in South Florida, there must be a way to further compress that hot air and pipeline it up north here during the winter months, no??? We don’t need to put BP/Amoco out of the natural gas business, we’d just like to be cut in for say, 1-2% of their heating fuel(s) market. Bottled hot air…can we market that?

Just had to reply for no other reason than to say that I am typing this sitting in Missouri in August and the temp outside is 62 degrees. Might even dip into the low 50s or upper 40s tonight or tomorrow night.


This is the best darn summer that I can remember. Usually it is hotter that hades in August in Missouri. It's the humidity that usually does us in.
