Description
The Goodman 2.5 Ton 14.5 SEER2 7.5 HSPF2 96.1% AFUE 80,000 BTU Hybrid Dual Fuel Heat Pump & Gas Furnace Split System Downflow R-32 with Dual Fuel Kit (GLZS4MA3010 / GDVT960804CN / CAPTA3626C3 / AFE18-60A) is a complete dual fuel heating and cooling system that pairs an electric heat pump with a gas furnace. This AHRI-matched system combines a 2.5-ton R-32 heat pump, 96.1% AFUE two-stage gas furnace, and cased evaporator coil so the heat pump handles cooling and mild-weather heating, while the furnace takes over when outdoor temperatures drop.
Designed for downflow installation, the system uses the furnace's variable-speed ECM blower motor to move air for both the heat pump and the gas burners. With a dual-fuel thermostat or outdoor temperature control, the system switches to gas heat below a set balance point, which keeps homes comfortable in cold snaps and lets you choose the more economical fuel for your local utility rates.

Compatibility & Installation Notes
The GLZS4MA3010 / GDVT960804CN / CAPTA3626C3 system is AHRI certified under reference number 216616932 and is designed for residential downflow applications. Compatibility with the property's ductwork, electrical service, gas supply, refrigerant lines, condensate drainage, and furnace venting must be confirmed before installation. The included Goodman AFE18-60A dual fuel kit turns the heat pump off whenever the furnace runs (except during defrost) and adds a 3-minute compressor anti-short-cycle delay. Use a heat pump thermostat with three heating stages for this two-stage furnace. An optional Goodman OT18-60A outdoor thermostat, or a dual fuel thermostat with an outdoor sensor, sets the switchover temperature.

Frequently Asked Questions
What is included in this Goodman HVAC system?
The package includes the GLZS4MA3010 heat pump, GDVT960804CN gas furnace, CAPTA3626C3 cased evaporator coil, and AFE18-60A dual fuel kit.
How does a dual fuel system work?
The heat pump cools in summer and heats in mild weather. When the outdoor temperature falls below the balance point set on the thermostat, the gas furnace takes over heating, so the system always runs on the more effective heat source.
What is the heating rating of the heat pump?
This matched system is rated at 7.5 HSPF2, with 28,200 BTU/h of heat pump heating at 47°F.
What is the cooling capacity of this system?
The system provides 2.5 tons with an AHRI-rated 28,600 BTU/h of cooling.
Is the furnace single-stage or two-stage?
The Goodman GDVT960804CN is a two-stage gas furnace.
What does 96.1% AFUE mean?
It means approximately 96.1% of the furnace's fuel is converted into usable heating energy.
Does this system use R-32 refrigerant?
Yes. The heat pump and evaporator coil are designed for R-32 refrigerant.
