Goodman alzs5ba1810 Split Heat Pump 1.5 Ton 15.2 SEER2

Product Description

The GOODMAN alzs5ba1810 is a 1.5-ton single-stage outdoor split heat pump rated at 15.2 SEER2 and 7.8 HSPF2, using R-32 refrigerant. It delivers 18,000 BTU/h nominal heating capacity and 17,800 BTU/h rated heating output. The unit operates on 208/230 volts single-phase power at 60 Hz and uses a scroll compressor with top-discharge airflow. It is designed for installation by licensed HVAC technicians in residential and light commercial applications where DOE regional compliance for all climate zones is required. ENERGY STAR certified and ISO certified, it meets current federal efficiency standards and suits new construction or replacement system projects.

The alzs5ba1810 is suited for residential and multi-family installations requiring a non-communicating, single-stage outdoor heat pump. Its wide operating range spans -20 degrees F to 70 degrees F for heating and 55 degrees F to 125 degrees F for cooling, making it viable in climates with significant seasonal temperature swings. The top-discharge cabinet design accommodates standard pad or rooftop placement. Standard line set lengths support runs up to 200 feet horizontal and 79 feet vertical, with a factory refrigerant pre-charge covering the first 15 feet of line set.

Key Features

• 15.2 SEER2 and 7.8 HSPF2 efficiency ratings meet DOE compliance for all U.S. regions
• R-32 refrigerant with factory charge of 88 oz and additional charge rate of 0.55 lb per foot beyond pre-charged length
• Single-stage scroll compressor with single-speed motor for straightforward controls integration
• Heating operation down to -20 degrees F ambient for cold-climate performance
• ENERGY STAR certified and ISO certified
• Sound pressure level of 70 dBA at high cooling operation

Compatibility

Designed as a non-communicating outdoor split heat pump for pairing with compatible indoor air handler or coil units. Component product references noted in product data include 0161R00128, ABK-20, CSR-U-1, FSK01A, OT18-60A, and TXV-FX-KX-2T. Verify indoor unit compatibility and refrigerant circuit sizing against the full system submittal before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician holding EPA Section 608 certification for R-32 refrigerant handling, as R-32 is an A2L mildly flammable refrigerant subject to specific safe-handling requirements. Disconnect and lock out all electrical power before making any electrical or refrigerant connections. Liquid line connection is 3/8 inch OD and suction line connection is 3/4 inch OD; confirm line set sizing and length against manufacturer guidelines before brazing. Refer to the equipment installation manual and all applicable local mechanical and electrical codes before commissioning.
