Some like Trane encode the efficiency of the equipment in the model, others do not. Each manufacturer categorizes their equipment differently. The model is designated as a field on the label and is easy to identify. If not, it can be found on the label pretty easily. Normally they have a logo prominently placed. The make should be pretty easy to figure out. From these we can determine the age, size, and type of equipment. The ones we are most interested in are the model and serial numbers. On this label you’ll find lots of numbers and letters. On some older systems near the bottom right above the lines on newer systems closer to the top. On a split system the label is often found on the same side as the refrigerant lines enter the system. On a package system it is usually on the right side of the equipment, near where the gas and power connect to the system.

Do this on the outdoor unit, whether it’s a split system or package system. To identify the make, model, age, and size you will need to find the manufacturers label. Step 2: Identifying the Make, Model, Age, and Size The condensing unit will be located outside the house and has a more traditional look, similar to the picture below. Inside, usually in the attic, crawlspace, or closet is the component that contains the blower, furnace (if equipped) and evaporator coil. In this setup the outdoor unit has the shape that most people associate the air-conditioners. The split A/C and Furnace is the type of system most people are familiar with. The actual look will vary based on equipment but when you can see the metal box between the unit and the house like the picture below you’ve got a package unit. Because a package unit is all-in-one box the supply and return ducts connect right to the unit and the heated or conditioned air is delivered right into the house. This is called the rain shield and it protects the ductwork from rain, debris, and critters. If you have a package unit you will notice a large hood made of metal that looks like a box between the unit and your house. You can best identify the package unit by looking at the unit (outdoors). Step 1: Visual Identification of System Type Package UnitsĪ package unit is an “all-in-one” system that does everything in one large box.
