Answer
When a Comfortmaker system by International Comfort is serialised, the first two digits after a single letter represent the year the system was manufactured by the company. As a result, the serial number shown below shows that it was manufactured in 2007.
Age: The first two digits of the serial number represent the week, and the third and fourth digits show the year, and the last two digits indicate the month. During the 1960s and early 1970s, this was the final four digits of a phone number. The date of manufacturing information is situated closer to the centre of the serial number, which indicates that it was manufactured more recently.
Comfortmaker is a subsidiary of the carrier group of companies. The units are very similar in appearance. An aircraft carrier unit may include a few extraneous features, but that is basically all there is to it. The same compressors are used.
A Comfortmaker air conditioner or furnace’s serial number may be used to determine the age of the system. When a Comfortmaker system by International Comfort is serialised, the first two digits after a single letter represent the year the system was manufactured by the company. As a result, the serial number shown below shows that it was manufactured in 2007.
Look at the model number on the compressor (which can be found on the data plate printed on the actual side of the compressor), and it should be a number that is divisible by 12. For domestic air conditioning systems, the temperature should begin at 18 degrees and not exceed 60 degrees. 18 tonnes of cooling equals 1.5 tonnes, and 60 tonnes of cooling equals 5 tonnes.
Look for the model number. You should be able to discover an even two-digit number somewhere in this string of letters and digits. Residential apartments are available in sizes ranging from 18 to 60 square feet. To calculate the tonnage of your air conditioning unit, divide the figure by 12 (which equals 12,000 Btu/hr, or one tonne of cooling capability).
On the website, you may look up warranty information. To access the Warranty section of the website, go to the horizontal navigation bar at the top of the page. Enter the serial number of the piece of equipment you’d like to get more information on. To look up your warranty, click on the Lookup Warranty icon.
Go to the outer cabinet of the air conditioning system and unplug the system. You’ll notice a metal plaque connected to it that contains the technical specifications for the system. On the majority of models, the nameplate is permanently attached to the rear of the cabinet. The manufacturer’s date, which should be shown as a month and year, should be located at the top of the nameplate.
Location. The model number may be found on a rating plate sticker that is connected to the interior of the unit on the left side, towards the top, on the inside of the unit. In order to get access to the sticker, you must first remove and put aside the front door of your furnace.
Model Identification Numbers “Model number” is imprinted on the unit nameplate or rating plate to distinguish it from other units of the same model number. A furnace identification plate may be seen on the inside of a cabinet, near the entrance panel, on both gas and oil furnaces for domestic use. Alternatively, the plate may be seen on the exterior of certain other Lennox products.
The sequence of digits and letter that follow the term “Serial” on the identifying plate may be found by looking at it. The first five digits of the Serial Number should be written down. As an example, consider the serial number 5498L9988. The code “5498L” will provide you with the location, year, and month in which the Lennox air conditioning unit was manufactured.
What is the best way to determine the age of a Lennox heat pump or air conditioner based on the model number? The year of manufacturing for Lennox units is represented by the second and third digits of the serial number. 2010 was the year when this unit was built.
SEAER is an abbreviation for “Seasonal Energy Efficiency Ratio,” which is often referred to [incorrectly] as “Seasonal Energy Efficiency Rating” in the industry. The SEER rating of an air conditioner is the ratio of the cooling output of the air conditioner over a normal cooling season divided by the amount of energy it used in Watt-Hours.
Air conditioners and heat pumps from Lennox® are available in a variety of tonnages ranging from 1.5 to 5 tonnes in capacity. Lennox package units are available in a variety of tonnages ranging from 2 to 5 tonnes in capacity.
Open the refrigerator door and search for the serial number on the inside. It will be on a sticker, which will usually be found on the inside of the door frame. If it isn’t present, check the freezer’s inside for it. Make a note of the whole serial number.
Once you’ve located the serial number, pay attention to the first four digits of the number. The first two numbers might represent the week of the year in which the unit was made, with the third and fourth digits representing the year in which the unit was manufactured. For example, a serial number beginning with 0193 may indicate that the item was manufactured during the first week of 1993.
Remove the top-front service panel from your furnace and look to the left side of the inner cabinet or to the top of the blower deck, depending on whether your system is an 80 percent or 90 percent AFUE type.
