Goodman 3.5 Ton 14.3 SEER2 Heat Pump + 80k BTU 96% AFUE Gas Furnace System – GLZS5BA4210 / CHPTA4230C3 / GD9S960804CN

Description

The GLZS5BA4210 dual-fuel heat pump and gas furnace system is a complete Goodman 3.5-ton, 14.3 SEER2 heat pump package: the GLZS5BA4210 outdoor unit paired with the CHPTA4230C3 evaporator coil and the GD9S960804CN gas furnace, sold together as one AHRI-certified match so the efficiency on the label is the efficiency you actually get.

Complete Goodman 3.5-ton heat pump system with gas furnace, rated at 14.3 SEER2.

This complete system is an AHRI Certified match (Ref. #215382792) — the components are factory-rated to deliver the listed efficiency together.

Where the GLZS5BA4210 system fits

A 3.5-ton system moves 42,000 BTU/h of cooling. As a rough rule of thumb in a moderate climate, that covers roughly 1,800 to 2,100 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) before you commit to the GLZS5BA4210. Oversized equipment short-cycles and leaves the house humid; undersized equipment runs all day on the hottest afternoons.

The GD9S960804CN furnace is an 80,000 BTU/h input, 96% AFUE unit, which works out to roughly 76,800 BTU/h of delivered heat. That pairs naturally with a 3.5-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.

Because this is a dual-fuel layout, the GLZS5BA4210 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.

Efficiency: 14.3 SEER2 and 96% 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 — 14.3 SEER2 is roughly equivalent to 15.1 SEER under the old method. Higher SEER2 means less electricity per unit of cooling delivered over a season.

Note that the GLZS5BA4210 on its own is rated 15.2 SEER2; matched with the CHPTA4230C3 and GD9S960804CN this specific combination is AHRI-rated at 14.3 SEER2. That gap is exactly why buying the matched set matters — the indoor coil and blower are part of the efficiency, not an afterthought. Certificate #215382792 is on file in the AHRI Directory of Certified Product Performance.

AFUE (Annual Fuel Utilization Efficiency) is the heating-side number: 96% AFUE means about 96 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 GLZS5BA4210 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.
• Outdoor unit: GLZS5BA4210, 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: GD9S960804CN, Downflow configuration. Confirm gas type, venting and combustion-air requirements for your location.
• Coil: CHPTA4230C3, 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 GLZS5BA4210 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. Register at Goodman product registration.

GLZS5BA4210 system FAQ

Is the GLZS5BA4210 a heat pump or an air conditioner?

The GLZS5BA4210 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.

What size home does a 3.5-ton system cover?

Roughly 1,800 to 2,100 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 GLZS5BA4210 system AHRI certified?

Yes — this exact combination is listed under AHRI certificate #215382792, which is what most utility rebate programs ask for.

Can the GD9S960804CN furnace be installed horizontally?

The GD9S960804CN is a Downflow furnace, so it is designed for the orientation shown; check the installation manual before planning a horizontal set.
