System specifications

Where the GLZS4MA2410 system fits

A 2-ton system moves 24,000 BTU/h of cooling. As a rough rule of thumb in a moderate climate, that covers roughly 900 to 1,200 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 GLZS4MA2410. Oversized equipment short-cycles and leaves the house humid; undersized equipment runs all day on the hottest afternoons.

This is an all-electric layout: the GLZS4MA2410 heat pump provides both heating and cooling through the AWST24SU1305 air handler. For backup and defrost-cycle heat, the air handler accepts an optional electric heat kit sized to your climate — Air handlers explained covers heat kits and configurations.

Efficiency: 14.3 SEER2 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 — our guide to SEER2, EER2 and HSPF2 covers how much efficiency is worth paying for.

The pairing above is listed under certificate #215217633 in the AHRI Directory of Certified Product Performance, which is the independent record utilities and inspectors check for rebates and code compliance.

Installation notes for the GLZS4MA2410 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: GLZS4MA2410, 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.
• Air handler: AWST24SU1305. Size the breaker and any electric heat kit to the unit’s data plate.
• Thermostat: use a heat-pump-compatible thermostat (O/B reversing-valve terminal).
• 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 GLZS4MA2410 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.
