How do you read Goodman tonnage?

The model number includes the nominal cooling capacity in three digits beginning with zero. This three-digit number is the unit’s capacity measured in British Thermal Units. For example, “018” indicates 18,000 BTUs. To calculate tonnage, divide the BTUs by 12,000, which is the weight of one refrigeration ton.

Look at the tag on the outdoor unit there will be a 2 digit # in the model # such as 24, 30,36,42,48,54,or 60. That is the capacity in 1000`s of btu. Then divide that # by 12000 for the tonnage.

Similarly, you may ask, how do I read my Goodman serial number?

The first two digits of the serial number are the year of manufacture for a Goodman heat pump or air conditioner. This unit was manufactured in 2013.

How can I tell what size my Goodman condenser is?

You can determine the “nominal” size of your HVAC system by examining the model number on the data plate at the side of the condenser (outdoor unit). Just like the nominal size of lumber or an air conditioning filter, the exact cooling capacity may be a little more or less than the nominal rating, but it’s close.

How many square feet does a 2 ton AC cool?

Air Conditioning Square Footage Range by Climate Zone ZONE 1 ZONE 2 1.5 Tons 600 – 900 sf 600 – 950 sf 2 Tons 901-1200 sf 951 – 1250 sf 2.5 Tons 1201 – 1500 sf 1251 – 1550 sf 3 Tons 1501 – 1800 sf 1501 – 1850 sf

How is tonnage calculated?

Tonnage, in shipping, the total number of tons registered or carried or the total carrying capacity. Gross tonnage is calculated from the formula GT = K1V, where V is the volume of a ship’s enclosed spaces in cubic metres and K1 is a constant calculated by K1 = 0.2 + 0.02 log10 V.

How many square feet will a 2.5 ton AC unit cool?

According to this common but somewhat inaccurate method, you need 1 ton of air cooling capacity for every so many square feet of living space. While there’s some dispute over the exact amount, an often-used amount is 600 square feet. A 2.5-ton unit, then, theoretically would fit a 1,500-square-foot home.

What is the meaning of 1 ton AC?

What Is a Ton and What Does it Mean for Air Conditioning? A ton is the cooling capacity of an air conditioning system. One ton is equal to the amount of heat required (288,000 Btu) to melt one ton of ice in a 24-hour period. A one-ton air conditioner is rated at 12,000 Btu per hour (288,000/24).

How much is a 5 ton unit?

Average AC Unit Prices by Size or Capacity Central AC Unit Size AC & Coil AC & Coil Installed Cost 3 Tons, 36,000 btu $1,650 $2,990 3.5 Tons, 42,000 btu $1,780 $3,250 4 Tons, 48,000 btu $1,860 $3,350 5 Tons, 60,000 btu $1,920 $3,590

How many tons should my AC be?

Understand here that the standard practice among HVAC contractors sizing air conditioners for new homes is to use a rule of thumb. It’s often in the neighborhood of 1 ton of air conditioning capacity for each 600 square feet of conditioned floor area, usually abbreviated 600 sf/ton.

How do I read my AC model number?

Look at the model number (Located on the data plate stamped on the actual side of the compressor) on the compressor and there should be a number divisible by 12. It should start at 18 and not be more than 60 for residential AC units.

How much refrigerant is in a 3 ton unit?

General Rule of Thumb 3-ton AC or Heat Pump with a 35 foot lineset will need a total of approximately 6-12 pounds of refrigerant, to fully recharge from empty. This includes the lineset, coil and unit.

Is it bad to have an oversized AC unit?

Since an oversized air conditioner does not remove enough moisture from the air, it can have very serious consequences for your home. Wood products, paint and drywall can suffer from too much moisture.

What size central air conditioner do I need for a 2000 sq ft home?

STEP 1: Determine how many BTUs of heating and tons of AC you need House Square Footage BTUs Needed 1,000 – 1,200 21,000 1,200 – 1,400 23,000 1,400 – 1,500 24,000 1,500 – 2,000 30,000

Why is AC measured in tons?

The use of tons to measure cooling capacity comes from this time. A ton refers to the amount of heat it takes to completely melt a ton of ice. The capacity of an air conditioner refers to the amount of heat it can remove. Rounding up 11,917 Btu/hr gives you 12,000 Btu/hr, which is one ton of air conditioner capacity.

How can you tell how old your AC unit is?

Go to the outside cabinet of the air conditioning system. You’ll find a metal nameplate attached to it containing the system’s technical specs. On most units, the nameplate is fixed to the backside of the cabinet. Near the top of the nameplate you should see the manufacturer’s date as a month and year.
