How to Decode Your Heil Package Unit Serial Number

Every Heil HVAC unit has a unique serial number that encodes critical information about the unit. Heil uses a Year-Week (YYWW) format, where specific characters represent the manufacturing date, production facility, and unit sequence number.

For example, the serial number "E2234567890" can be decoded as follows: the first characters indicate the manufacturing date, while subsequent digits identify the production line and unit number. Our free decoder tool automatically parses this format and reveals the complete manufacturing history.

Maintenance Schedule for Heil Package Unit

Replace or clean air filters: Every 1-3 months. Clean condenser coils: Annually (spring). Check refrigerant levels: Annually. Inspect electrical connections: Annually. Clean evaporator drain line: Every 6 months. Test thermostat calibration: Annually. Inspect ductwork for leaks: Every 2-3 years.

Heil Package Unit Efficiency Over Time

Heil 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 Heil models range from 14 to 26+ SEER.

Regarding refrigerants: Heil 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.
