Where the GLXS4BA4210 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 GLXS4BA4210. Oversized equipment short-cycles and leaves the house humid; undersized equipment runs all day on the hottest afternoons.

The GDVT801005CX furnace is a 100,000 BTU/h input, 80% AFUE unit, which works out to roughly 80,000 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.

Efficiency: 15.2 SEER2 and 80% 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.

Note that the GLXS4BA4210 on its own is rated 14.3 SEER2; matched with the CAPTA6030C3 and GDVT801005CX this specific combination is AHRI-rated at 15.2 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 #214859899 is on file in the AHRI Directory of Certified Product Performance.

AFUE (Annual Fuel Utilization Efficiency) is the heating-side number: 80% AFUE means about 80 cents of every fuel dollar becomes heat in the house over a season. An 80% furnace vents through a conventional metal flue and does not need a condensate drain, which keeps installation simpler and is often the practical choice where the existing chimney or B-vent is in good shape.

Installation notes for the GLXS4BA4210 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: GLXS4BA4210, 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: GDVT801005CX, Downflow configuration. Confirm gas type, venting and combustion-air requirements for your location.
• Coil: CAPTA6030C3, Upflow/Downflow. Match cabinet width and airflow direction to the furnace or air handler it sits on.
• Thermostat: any standard cooling/heating thermostat works.
• 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 GLXS4BA4210 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.
