How do I read my comfortmaker model number?
For Comfortmaker, you should look for two numbers at the far side of the middle of the cluster of numbers in the model number that are divisible by 6 or 12, which represent the nominal BTU of the system in thousands.
How do I know the tonnage of my furnace?
Measure the square footage of every room and hallway in your house. Add your findings to determine your house’s total square footage. Multiple the total square footage by 35 to determine the BTU capacity your furnace needs. Divide the result by 12,000 to figure out the tonnage requirement for the furnace.
How do I know what tonnage my compressor is?
Divide the number listed by 12,000. This will tell you how many tons your HVAC compressor is. For example, if the BTU number listed is 36,000, divide it by 12,000 and you’ll see that you have a 3 ton unit.
Are comfortmaker and carrier the same?
Comfortmaker is a subsidiary of carrier. The units are virtually identical. There may be a few more unnecessary bells and whistles on a carrier unit, but that’s about it. Same compressors.
How do you read carrier serial numbers?
The most common way to to determine the carrier ac age is through the serial number. In the above style, the determining factor is having a letter in the middle of the serial number. The first two digits are the week of manufacturer. The second set of digits are the year of manufacture.
How many BTUs are in a ton?
12,000 BTU
There’s a complicated mathematical formula involved in converting the weight of that ice into energy, but in the end a “ton” of air conditioning capacity represents roughly 12,000 BTU per hour. So a 2-ton unit has 24,000 BTU/hr capacity and a 3-ton has 36,000 BTU/hr, and so on.
How do you determine tonnage?
Simply divide the BTUs by 12,000 to calculate the tonnage of your unit. For example, if your air conditioner is 36,000 BTUs, you have a 3 ton unit. Some manufacturers bury tonnage or BTU information in their model numbers. Look for an even, two-digit number between 18 and 60.
How many tons is a Comfortmaker air conditioner?
For Comfortmaker, you should look for two numbers at the far side of the middle of the cluster of numbers in the model number that are divisible by 6 or 12, which represent the nominal BTU of the system in thousands. A ton of air conditioning equals 12,000 BTU, and 48 divided by 12 equals 4, so the data plate below indicates the system is 4 tons.
How many tons is an Amana air conditioner?
Here’s a rundown of the range you will encounter: 18 = 1.5 tons, 24 = 2 tons, 30 – 2.5 tons, 36 = 3 tons, 42 = 3.5 tons, 48 = 4 tons, and 60 = 5 tons. If you are unsure whether you have found the right two numbers, you can double-check it by looking for the “RLA” rating on the data plate.
How to calculate the tonnage of an air conditioner?
RLA is an acronym for R ated L oad A mperage, and is what the maximum amperage should be when the condenser up and running. If you divide the RLA by 6 for older units and 5 or 6 for newer units, you should get a number that approximates (not exactly) the tonnage of the system.
