Key Features

What sets the GLZS5BA3610A apart

Heats AND Cools

Unlike a standard air conditioner, a heat pump reverses its refrigerant cycle to both cool your home in summer and heat it in winter. One outdoor unit delivers year-round comfort with a single refrigerant system — no separate furnace required in mild-to-moderate climates.

R-32 Refrigerant

Built for R-32, the next-generation residential refrigerant with lower environmental impact than the outgoing R-410A standard. R-32 requires less charge per system and delivers improved thermodynamic performance, helping meet current EPA and AIM Act requirements.

Single-Stage Scroll Compressor

A proven single-stage scroll compressor provides reliable, consistent performance in both heating and cooling modes. Scroll technology is known for smooth operation, high efficiency, and long service life.

15.2 SEER2 Efficiency

Rated at 15.2 SEER2 under the current M1 testing standard. Pair with a matched indoor coil or air handler for AHRI-certified system performance in both heating and cooling modes.

Durable Outdoor Construction

Heavy-gauge galvanized steel cabinet with louvered coil guard protects internal components from impact and debris. Engineered for year-round outdoor operation through both heating and cooling seasons.

Backed by Goodman

Covered by Goodman's 10-Year Parts Limited Warranty and 10-Year Compressor Limited Warranty when registered within 60 days of installation.

This Goodman GLZS5B heat pump condenser delivers 3.0 ton of cooling and heating capacity (36,000 BTU) at 15.2 SEER2 efficiency, running on R-32 refrigerant. The high-efficiency scroll compressor and SmartShift® defrost technology provide quieter, more reliable operation in cold weather, and the unit is ENERGY STAR certified. AHRI Certified and ETL Listed.

  • High-efficiency scroll compressor — delivers improved seasonal efficiency over reciprocating designs.
  • SmartShift® defrost technology — manages the defrost cycle quietly, reducing the abrupt sounds typical of older heat pumps.
  • Pre-charged with R-32 refrigerant — factory-charged for 15 feet of line set to reduce installation time.
  • Copper tube / enhanced aluminum fin coil — 5mm-diameter design on 1.5–3.5 ton models for efficient heat transfer.
  • Factory-installed compressor crankcase heater — keeps oil viscosity correct in cold weather for reliable cold-temperature starts.
  • Factory-installed suction-line accumulator — protects the compressor from liquid refrigerant slugging during defrost.
  • ENERGY STAR certified — meets EPA efficiency criteria when properly matched with an indoor coil or air handler.
  • Sweat-connection service valves — easy-access gauge ports for installation and seasonal service.

Frequently Asked Questions

How does a heat pump work?
A heat pump uses refrigerant to move heat between the inside and outside of your home. In summer it works like an air conditioner — absorbing heat from inside and releasing it outdoors. In winter, a reversing valve flips the cycle: the heat pump extracts heat from the outdoor air (even when it's cold) and moves it inside. This makes a heat pump a year-round heating and cooling solution in a single outdoor unit.
What size home does a 3.0-ton heat pump serve?
A 3.0-ton heat pump is generally appropriate for homes in the 1,500–2,000 sq. ft. range for cooling, though heating loads and climate zone can affect sizing. A professional Manual J load calculation is the most accurate way to determine the right capacity for your specific home, especially in regions with significant heating demand.
What does SEER2 mean?
SEER2 (Seasonal Energy Efficiency Ratio 2) measures cooling efficiency under the updated M1 testing standard adopted in 2023. A higher SEER2 number means lower electricity costs to deliver the same cooling. The GLZS5BA3610A is rated at 15.2 SEER2. For heating efficiency, heat pumps are rated by HSPF2 — refer to the full specification sheet for HSPF2 data specific to your matched system.
Can a heat pump heat my home in cold weather?
Modern heat pumps can deliver useful heating capacity well below freezing, though heating output does decrease as outdoor temperatures drop. In colder climates, heat pumps are commonly paired with supplemental electric heat strips in the indoor air handler, which automatically engage when outdoor temperatures fall below the heat pump's balance point. Your HVAC contractor can determine whether supplemental heat is recommended for your climate zone.
Do I need backup heat strips?
Backup heat strips are usually installed in the indoor air handler as a safety net for very cold days and for emergency heat when the heat pump is being serviced. Whether you need them depends on your climate, home insulation, and heating load. Most installations in climates that see freezing temperatures include a matched air handler with electric heat kit accommodation.
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.
Can I pair this with my existing indoor coil or air handler?
The GLZS5BA3610A is an R-32 heat pump condenser and must be paired with an R-32-compatible indoor coil or air handler. It is not compatible with older R-410A or R-22 equipment. For best performance and to maintain the AHRI-rated SEER2 efficiency, pair it with a factory-matched Goodman indoor unit. Your HVAC contractor can confirm compatibility.
Do I need AHRI-certified matching?
The rated SEER2 efficiency applies when the condenser is paired with specific matched indoor components. Installing the GLZS5BA3610A with a non-matched coil can reduce actual efficiency below the rated value, affect warranty coverage, and in some cases may not meet local building code minimums. Always install as part of an AHRI-certified matched system.
How loud is 71.1 dB in practical terms?
71.1 dB is typical for a 3.0-ton residential heat pump condenser. For reference, normal conversation is around 60 dB, a dishwasher runs around 70 dB, and a gas lawn mower measures around 85 dB from 50 ft. Place the unit away from bedroom windows and patios when possible, and follow Goodman's installation clearance requirements for proper airflow and serviceability in both heating and cooling modes.
What maintenance does a heat pump need?
Keep the condenser coil clear of leaves, grass clippings, and debris. Maintain at least 24 inches of clearance on all sides for airflow. Have a licensed HVAC technician perform an annual tune-up (ideally before each cooling season) including coil cleaning, refrigerant charge verification, reversing valve check, and electrical inspection. In winter, keep snow and ice from accumulating on or around the outdoor unit.
How do I register for the 10-year warranty?
Register the unit online at Goodman's warranty registration page within 60 days of installation. You'll need the model number (GLZS5BA3610A), serial number (found on the data plate), installation date, and installing contractor information. Without registration, the warranty reverts to a shorter base term.
