Description
The Goodman 3.5 Ton 17 SEER2 8.6 HSPF2 97% AFUE 120,000 BTU Hybrid Dual Fuel Heat Pump & Gas Furnace Split System Upflow R-32 (GZV7SA4210 / GRVM971205DN / CHPEA4830D3) 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 3.5-ton R-32 heat pump, 97% AFUE modulating 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 upflow 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 GZV7SA4210 / GRVM971205DN / CHPEA4830D3 system is AHRI certified under reference number 215434324 and is designed for residential upflow applications. Compatibility with the property's ductwork, electrical service, gas supply, refrigerant lines, condensate drainage, and furnace venting must be confirmed before installation. The communicating GZV7SA4210 heat pump and GRVM971205DN furnace connect over the two communication wires, and the furnace control manages dual fuel switchover on its own, so a standard single-stage 24 VAC thermostat is all you need. No separate dual fuel kit is required.

Frequently Asked Questions
What is included in this Goodman HVAC system?
The package includes the GZV7SA4210 heat pump, GRVM971205DN gas furnace, and CHPEA4830D3 cased evaporator coil.
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 8.6 HSPF2, with 41,000 BTU/h of heat pump heating at 47°F.
What is the cooling capacity of this system?
The system provides 3.5 tons with an AHRI-rated 40,500 BTU/h of cooling.
Is the furnace single-stage or two-stage?
The Goodman GRVM971205DN is a modulating gas furnace.
What does 97% AFUE mean?
It means approximately 97% 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.
