System specifications

Where the GLZS5BA3610 system fits

A 3-ton system moves 36,000 BTU/h of cooling. As a rough rule of thumb in a moderate climate, that covers roughly 1,500 to 1,800 square feet of reasonably insulated living space — but square footage is only a starting point. Ceiling height, insulation, window area, sun exposure and duct condition all move the number, so run a proper load calculation (or use our free HVAC system sizing tool and the Goodman sizing and configuration guide) before you commit to the GLZS5BA3610. Oversized equipment short-cycles and leaves the house humid; undersized equipment runs all day on the hottest afternoons.

The GR9S921004CN furnace is a 100,000 BTU/h input, 92% AFUE unit, which works out to roughly 92,000 BTU/h of delivered heat. That pairs naturally with a 3-ton cooling load in most of the country; homes in the coldest climates or with long, leaky duct runs sometimes step up one furnace size, which is another thing a load calculation will tell you. For stages, venting and AFUE trade-offs, see the Goodman gas furnace guide.

Because this is a dual-fuel layout, the GLZS5BA3610 heat pump carries the heating load in mild weather at heat-pump efficiency, and the gas furnace takes over when outdoor temperatures drop below the balance point. A dual-fuel-capable thermostat (or a fossil-fuel kit) manages that handoff automatically — it is the most cost-effective way to heat in climates with cold snaps but mild shoulder seasons. Our dual-fuel guide walks through the cost math.

Efficiency: 15.2 SEER2 and 92% AFUE explained

SEER2 is the cooling-efficiency rating under the U.S. Department of Energy’s 2023 test procedure. It uses a higher external static pressure than the old SEER test, so SEER2 numbers read a little lower than the SEER figures on older equipment — 15.2 SEER2 is roughly equivalent to 16.0 SEER under the old method. Higher SEER2 means less electricity per unit of cooling delivered over a season — our guide to SEER2, EER2 and HSPF2 covers how much efficiency is worth paying for.

The pairing above is listed under certificate #215382705 in the AHRI Directory of Certified Product Performance, which is the independent record utilities and inspectors check for rebates and code compliance.

AFUE (Annual Fuel Utilization Efficiency) is the heating-side number: 92% AFUE means about 92 cents of every fuel dollar becomes heat in the house over a season. A condensing furnace like this one pulls extra heat out of the exhaust, so it vents through PVC pipe and needs a condensate drain — plan for both in the install.

Installation notes for the GLZS5BA3610 system

• Refrigerant: R-32. This is a low-GWP A2L refrigerant, not a drop-in for R-410A — line sets, tools and service practices must be R-32 rated, and the work belongs to a licensed HVAC contractor. R-32 vs R-454B explains why the industry moved to these refrigerants.
• Outdoor unit: GLZS5BA3610, single-stage, standard 208/230 V single-phase residential service. Set it on a level pad with clearance on all sides for airflow and service.
• Furnace: GR9S921004CN, Upflow/Horizontal configuration. Confirm gas type, venting and combustion-air requirements for your location.
• Coil: CHPTA3630B3, Horizontal. Match cabinet width and airflow direction to the furnace or air handler it sits on.
• Thermostat: use a dual-fuel-capable thermostat so the heat pump and furnace hand off correctly.
• Not included unless listed above: line set, thermostat, equipment pad, disconnect and any electric heat kit. Call (877) 843-4822 and we will spec them with you.

Warranty and registration

Goodman residential equipment carries a 10-Year Parts Limited Warranty when the equipment is registered online within 60 days of installation; unregistered units revert to the shorter base term, so register every component of the GLZS5BA3610 system as soon as it is installed. Heat-exchanger and compressor coverage vary by model — the exact terms are on the warranty certificate packed with each unit; our HVAC warranty guide explains what voids coverage.

GLZS5BA3610 system FAQ

Is the GLZS5BA3610 a heat pump or an air conditioner?

The GLZS5BA3610 is a heat pump — it cools in summer and reverses to heat in winter, with the gas furnace covering the coldest days in this dual-fuel package. The Goodman heat pump guide covers the model lineup and SEER2 tiers.

What size home does a 3-ton system cover?

Roughly 1,500 to 1,800 square feet as a rule of thumb, but a load calculation is the only reliable answer. Our sizing tool takes about two minutes.

Does this system include a thermostat and line set?

No. Only the components listed under “What’s included” ship with this system. Line set, thermostat, pad and disconnect are sold separately.

Is the GLZS5BA3610 system AHRI certified?

Yes — this exact combination is listed under AHRI certificate #215382705, which is what most utility rebate programs ask for.

Can the GR9S921004CN furnace be installed horizontally?

The GR9S921004CN is an Upflow/Horizontal furnace, so yes — it can be set upright or on its side in an attic or crawlspace, following the installation manual for orientation-specific parts.
