WE SUGGEST USING WORST CASE SCENARIO INFORMATION TO AVOID UNDERSIZING YOUR COOLING SYSTEM. SOME CUSTOMERS CHOOSE TO SELECT AN OPTION WITH 500–1,000 MORE BTUS THAN CALCULATED AS AN ADDED BUFFER. WE HIGHLY RECOMMEND THIS FOR CUSTOMERS IN CONSISTENTLY HUMID CLIMATES, AS HIGH AMBIENT HUMIDITY PLACES ADDITIONAL STRAIN ON THE COOLING SYSTEM BEYOND WHAT THE CALCULATOR ACCOUNTS FOR. SIMILARLY, IF YOUR CELLAR WILL EXPERIENCE FREQUENT OR REGULAR DOOR TRAFFIC — SUCH AS IN AN ENTERTAINING OR COMMERCIAL SETTING — ADDITIONAL BTU CAPACITY MAY BE WARRANTED.
