Arcoaire units use the Carrier serial scheme. Here is what each part of the serial number means, by production era:
A Arcoaire model number is usually built as [product series] · [cooling capacity in thousands of BTU] · [efficiency/SEER] · [voltage/phase] · [refrigerant/revision]. The capacity code is the most reliable part: divide it by 12 for the nominal tonnage — for example 036 = 3 tons, 048 = 4 tons. Enter your model number in the tool above to estimate the tonnage automatically.
Typical service life runs about 10–15 years for air conditioners and heat pumps and 15–20 years for furnaces. Most Arcoaire parts warranties run 5–10 years and often require registration within 60–90 days of installation. Decode the age above, then confirm exact coverage on the manufacturer's portal:
