Complete Heat Pump Split System 2.5 Ton · 14.5 SEER2 Heats + Cools R-32 Refrigerant Single-Stage Scroll
A complete, factory-matched heat pump system — cools in summer, heats in winter. This kit pairs an R-32 outdoor heat pump with a Multi-Position ECM air handler. The heat pump's reversing valve flips the refrigerant cycle seasonally, so one outdoor unit handles year-round comfort with a single refrigerant system.

Key Features

What sets this system apart

Complete Factory-Matched System

Both components — outdoor heat pump and indoor air handler — are engineered and AHRI-certified to work together. You get the published 14.3 SEER2 efficiency rating, correct refrigerant line sizing, compatible controls, and a single-source solution covered by Goodman's warranty.

Heats AND Cools

A reversing valve flips the refrigerant cycle between heating and cooling modes — the same outdoor unit that cools your home in summer also heats it in winter. 30,000 BTU/h of cooling capacity; 30,000 BTU/h of heating capacity at standard rating conditions.

R-32 Refrigerant

Built around R-32 — the next-generation residential refrigerant with lower environmental impact than R-410A. R-32 systems require up to 30% less refrigerant charge and deliver improved thermodynamic performance, meeting current EPA and AIM Act requirements.

Single-Stage Scroll Compressor

The outdoor heat pump uses a proven single-stage scroll compressor — reliable, consistent performance in both heating and cooling modes with smooth operation and long service life.

Multi-Speed ECM Blower

The air handler uses a Multi-Speed ECM (electronically commutated motor) that adjusts airflow precisely to demand. ECM blowers use significantly less electricity than older PSC motors, particularly during long low-speed operation, and run more quietly.

Backup Heat Kit Ready

The air handler accommodates field-installable electric heat kits (sold separately). In cold climates, a backup heat kit provides supplemental heat when outdoor temperatures drop below the heat pump's efficient operating range — important for homes in heating-dominant regions.

This complete Goodman heat pump split system pairs a 2.5 ton energy-efficient GLZS4B R-32 condenser with an AMST multi-position 9-speed ECM air handler and a matched electric heat kit, delivering 30,000 BTU of cooling and heating capacity at 14.5 SEER2 as an AHRI-matched system. SmartShift® technology manages the defrost cycle for quieter winter operation. AHRI Certified and ETL Listed; UL 60335-2-40 compliant.

  • Pre-charged with R-32 refrigerant — factory-charged condenser for 15 feet of line set to reduce installation time.
  • AHRI-matched system rating — this condenser/air handler/heat kit combination is rated as a system at 14.5 SEER2.
  • SmartShift® defrost technology — manages the defrost cycle quietly, reducing the abrupt sounds typical of older heat pumps.
  • Compressor crankcase heater — factory-installed for reliable cold-temperature starts.
  • Suction-line accumulator — factory-installed to protect the compressor from liquid refrigerant slugging during defrost.
  • A2L refrigerant compliance — air handler designed and tested to UL 60335-2-40 requirements for R-32 refrigerant safety.
  • Direct-drive 9-speed ECM blower motor — variable airflow speeds for matched comfort and efficiency.
  • Multi-position air handler — upflow, downflow, or horizontal — adapts to closets, attics, or basements.
  • Internal factory-installed TXV — thermal expansion valve included on the air handler for cooling and heat pump applications.
  • Electric heat kit included — matched HKTSN heat kit for supplemental heating in cold weather.

Frequently Asked Questions

What comes in this kit?
Two components shipped together: (1) the outdoor heat pump GLZS4BA3010A and (2) the indoor air handler AMST30BU13. Line set (refrigerant tubing), thermostat, ductwork, condensate drain, and electrical wiring are NOT included and are supplied by your HVAC contractor. Electric heat kits for cold-weather backup are also sold separately.
How does a heat pump heat my home?
A heat pump uses refrigerant to move heat between outdoors and indoors. In summer it absorbs heat from inside and releases it outside (cooling). In winter, a reversing valve flips the cycle: the outdoor unit extracts heat from the outdoor air (even when it's cold outside) and moves it inside. When outdoor temperatures drop below the heat pump's efficient operating range, supplemental electric heat kits installed in the air handler provide additional heat.
Heat pump vs. gas furnace — which should I choose?
Choose a heat pump if you're in an all-electric home, a mild-to-moderate climate, or want the efficiency benefits of electric heating. Choose a gas furnace (with a separate AC condenser) if you have natural gas service and are in a cold climate where gas heat is typically more cost-effective during the coldest months. Heat pumps have improved dramatically in cold weather performance over the past decade, but local utility rates and climate still matter.
Do I need a backup heat kit?
In mild climates, a heat pump alone is often sufficient. In colder climates, a field-installable electric heat kit is recommended — it runs when outdoor temperatures drop below the heat pump's efficient operating range and kicks in during defrost cycles. Your HVAC contractor can size the kit based on your climate zone and heating load. The air handler in this kit is designed to accommodate these heat kits.
Why buy as a matched kit vs. separate components?
Matched systems are AHRI-certified to deliver their published SEER2 rating — mixing components from different manufacturers or model families often results in lower real-world efficiency and can complicate warranty claims. The factory match also ensures refrigerant line sizing, TXV calibration, and airflow are correct from day one.
What size home does this system serve?
A 2.5-ton system is generally appropriate for homes in the 1,200–1,600 sq. ft. range for cooling. Heating load is more climate-dependent — a professional Manual J load calculation by your HVAC contractor is the most accurate way to confirm the right system size for your specific home, especially for heat pump sizing in regions with significant heating demand.
What is R-32 refrigerant?
R-32 is the next-generation residential refrigerant replacing R-410A. It has lower environmental impact, requires up to 30% less charge per system, and offers improved energy efficiency. R-32 is being adopted industry-wide to meet EPA and AIM Act requirements phasing down legacy refrigerants. R-32 systems are not backward-compatible with R-410A equipment.
Can the air handler install in any orientation?
Yes — the AMST30BU13 is a Multi-Position air handler, supporting all four installation orientations: upflow, downflow, horizontal-left, and horizontal-right. Your HVAC contractor will select the orientation based on your home's ductwork layout.
How do I register the warranty?
Each component must be registered separately at Goodman's warranty registration page within 60 days of installation. You'll need the model number and serial number (from each data plate), installation date, and installing contractor information for both the heat pump and air handler. Without timely registration, warranty terms revert to a shorter base period.
