How do you determine the tonnage of Goodman AC units?This number is located on a plate attached to the back of the unit, near the power supply and coolant lines. 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. For example, a unit with 18,000 BTUs has a tonnage of 1.5. As of 2014, the Goodman Manufacturing Company website provides product specifications, including model numbers, for all current air conditioning units and some older models. Does Goodman Heating manufacture air conditioners? Goodman produces both heating and air conditioning systems. As of 2015, Goodman has six different series of central air conditioning systems. How reliable is a Goodman AC unit? Recently-built Goodman air conditioning units are considered highly reliable, according to heating and air conditioning review website WebHVAC.

Coleman air conditioning units are available for purchase from American RV Company, AdventureRV.net and PPL Motor Homes, as of 2015. All three retailers se...

Let me show you how YOU the Realtor can determine that on your own.  Remember that these dates are NOT installation dates, but they are the manufacture date and typically these dates are close to each other. First let us understand “Tonnage” is: Tonnage  The unit of measure used in air conditioning to describe the cooling capacity of a system. One ton of cooling is based on the amount of heat needed to melt one ton (2000 lbs.) of ice in a 24 hour period.

One ton of cooling is equal to 12,000 Btu/hr. This size of an Air Conditioning Unit is based up many factors, such as composition of the building, which way it faces, the number of windows, the amount of insulation..... Basic Principals of Air Conditioning: The basic principals of the Air Conditioning System used for Florida.An AC system is used as a dual purpose.central air conditioning units efficiencyOne is to allow warm air to be pulled into the system, filter this air and then flow across the cold coils and blow cold air into the building.heat pump air conditioning package unitsThe other purpose is to pull the humidity out of the air.ac unit doesn't turn offThis is VERY important.So with this information – BIGGER IS NOT BETTER!

A house with to large an AC system will always be damp and contain that “bone chilling” cold.If in doubt call a Professional and licensed Heating, and Air Conditioning (HVAC) contractor. How to determine the age and size of the AC unit: The age or manufacture date of an AC compressor is usually coded under the serial number portion of the data plate that is present on the side of the compressor (Outside AC portion of the AC system) The red boxed area is the Serial Number for this type of unit.The “L” indicates the month of the manufacture.“L” being the 12thletter of the alphabet and the ‘01” being the last 2 numbers of the year, thus meaning this is a December 2001 manufacture date. This is the area where the data or information from above was obtained.The exterior portion of the AC system called the compressor. Congratulations on learning how to determine the age of an Air Conditioning Compressor.The air handler’s age is determined much the same way.

The air handler is located within the interior of the residence most of the time it is in a closet, garage or attic area.This applies to the MAJORITY of AC units in SW Florida.Other types are present, but this will allow you to determine the age of many of the AC systems. How to determine the size (called tonnage) of an Air Conditioning system: First of all the size of an AC unit is called a ton or tonnage.A recap of tonnage is Tonnage  The unit of measure used in air conditioning to describe the cooling capacity of a system. The number to remember is 12,000 BTU’s or more simply 12.If 12,000 BTU’s is equal to 1 (one) ton of AC then 18,000 is equal to 1.5 tons and 24,000 is equal to 2 tons and so on. 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.18 to equal 1.5 tons and 60 to equal 5 tons of cooling.

Look at the model number below and you determine the AC compressor size. The 36 in the model number in the first picture above it means that the AC compressor is equal to 3 tons of cooling. Once again, size is very important and detrimental to the proper operational status of an Air Conditioning System.More blog posts about heating and air conditioning: •The coils on my heat pump are covered with ice on cold mornings.

This means that a 12 SEER unit will cool your home using half the energy of a 6 SEER, and a new 13 SEER system is about 30% more efficient than a 10 SEER from the early 1990s. Two mandates by the U.S. Department of Energy have pushed minimum SEER ratings upward. Air conditioning units manufactured in1992 and later were required to have a minimum 10 SEER, and the minimum was reset again to 13 SEER in 2006. Today manufacturers offer a 15 SEER for about 20% more than a 13 SEER base model, and up to 20 and above is also available. While the chart above outlines average SEER ratings for each era of air conditioning production, if you want to know the exact SEER of your air conditioning system, go to our blog “How can I find out the SEER of my air conditioner?” While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector.
