Best Payne Equipment for Alabama's Climate
Payne has continuously improved efficiency to meet evolving federal standards. In 2006, the minimum was raised to SEER 13. In 2015, southern states moved to SEER 14. In 2023, new SEER2 standards took effect: 14.3 SEER2 (South), 13.4 SEER2 (North). Modern Payne models range from 14 to 26+ SEER.
Regarding refrigerants: Payne units before 2010 likely use R-22 (phased out since 2020 -- expensive and harmful). Units from 2010-2023 use R-410A. Newest models use R-32 or R-454B to meet EPA regulations. Knowing your refrigerant is critical -- R-22 refills cost $100-200+ per pound.
Alabama HVAC Efficiency Requirements
Payne model numbers contain encoded information about the equipment type, efficiency rating, capacity (tonnage), and product series. The first 2-3 characters typically indicate the product line and equipment category. The middle section encodes the SEER or AFUE efficiency and BTU capacity, while the trailing characters identify the specific revision.
Understanding your model number helps you order the correct replacement parts, verify warranty coverage, and ensure any new components are compatible with your existing system. Our decoder extracts all of this information automatically from the model number string.

Enter your Payne serial number into our free decoder. Payne uses a Week-Year (WWYY) format. We parse it instantly and calculate the exact age, plus a condition status.
Is Payne a good HVAC brand?
Payne is one of the most established manufacturers, founded in 1914 with over 112 years of experience. They offer 10-year limited parts and consistently rank among top brands.
What does a Payne serial number look like?
Payne serial numbers follow a Week-Year (WWYY) format. Example: "4520E98765". Find it on the metal data plate on the unit.
How long is the Payne warranty?
Payne typically offers 10-year limited parts on residential equipment when properly registered.
What is the difference between a Payne model number and serial number?
The model number identifies the product type, efficiency, and capacity (same for all identical units). The serial number is unique to each unit and encodes the manufacturing date and location. You need both to fully identify your Payne HVAC equipment.
Where is the serial number on a Payne unit?
The serial number is on the metal data plate (also called nameplate or rating plate). On outdoor units, check the side panel near the refrigerant lines. On indoor units, look on the front panel, inside the cabinet door, or near the electrical access panel.
Can I determine the tonnage from a Payne model number?
Yes. Payne model numbers encode capacity (BTU/h) in specific positions. For example, in model "PA13NA036000", the capacity digits indicate the BTU rating. Divide by 12,000 to get tonnage. Our decoder does this automatically.
What refrigerant does my Payne unit use?
Units manufactured before 2010 likely use R-22 (now phased out and expensive). Units from 2010-2023 typically use R-410A. Newest models may use R-32 or R-454B. Your model number can reveal the refrigerant type.
