That model number is for an air handler (indoor unit) and not associated with tonnage. Air handlers are more often rated according to CFM and auxiliary heat.
In order to get the tonnage you would need to look at the model number of the outdoor unit (likely a heat pump). Typically tonnage is expressed in 1000s of BTU/hr, i.e. 24 = 2.0, 30 = 2.5, 36 = 3.0, etc.
12,000 btu/ton. So figure 30÷12 its a 2.5 ton/30,000btu, IF the 30 is the tonnage. Not likely the 100 in the model# is your tonnage unless the a/c is the size of a small house.
when the outside and inside units are both the same size it's referred to as a 'matched' system, which is what 99 percent of all units are.
There are instances when the outside unit is bigger/smaller than the inside unit but as a rule you want the outside and inside units to be the same tonnage.
Hello, the tonnage on this unit is a 3 ton unit. Your model number tells you. The 036 is the tonnage. There are 12,000 btu's per ton, so 36 divided by 3 =12 or in this case 12,000 btu's. Sincerely, Shastalaker7 A/C, & Heating Contractor
Look for your model number on your condensor, outdoor unit. Your tonnage will be towards the end of it and divisable by 6. I.E. 36=3tons or 42=3.5tons. Ac units are messured by the half ton. If you have a split system I.E. heater inside and ac outside your system will be 1 - 5 tons. If this doesn't help post your model and serial number. I can then give you tonnage, age, so forth.
This is a 3 and 1/2 ton unit. The 042 in the model number is the tonnage of your carrier unit. AC tonnage is based on 12,000 btu per ton. 12,000.....1 ton 18,000.....1 and 1/2 ton 24,000.....2 ton 30,000.....2 and 1/2 ton 36,000.....3 ton 42,000.....3 and 1/2 ton 48,000.....4 ton 60,000.....5 ton. There is no 4 and 1/2 ton unit.
ok ready for this? To find the tonnage look at the serial # Tonnage is related to 12's If there, on the serial # there is say 0062490 the tonnage is 24 or two tons 24 divided by 12 equals 2 Say the serial # contains 0063090 then the tonnage is 2 1/2 because of the 30 hopefully you see what I am saying the number in the serial # if it can be divided by 12 or 6 this is the tonnage. If you will send me the serial number I will tell you the tonnage. The serial number is on the outside unit at the copper connections where the electrical lines go in.
Good luck on your repairs hope this helped send me a note online here and if you need I will give you tonnage if you send the model # and serial number with your response> I will check online around 1500 hours on 1/9/10 central time. Remember to look for the numbers that are divisible by either 12 or 6 on the serial number
In almost every case, most manufacturers put the tonnage in the model number. Look for something that is divisible by either 6 or 12. Something like, 24, 30, 36, and so on. Cfm has to match the tonnage. Usually in the neighborhood of 450 cfm per 12,000 btu's of cooling for the inside of the structure.
