Product Description

MRCOOL® VersaPro® 3 Ton Heat Pump + 80K BTU Gas Furnace Dual Fuel System

Get the flexibility of electric heat-pump heating, central air conditioning, and natural gas heat in one complete central ducted HVAC system with this MRCOOL® VersaPro® dual fuel bundle.

This system combines a 3 ton / 36,000 BTU MRCOOL VersaPro inverter heat pump, an 80,000 BTU input 80% AFUE VersaPro gas furnace, and a 2.5–3 ton pre-charged R-454B cased A-coil.

The furnace and coil both feature a 17.5-inch cabinet width, creating a properly aligned indoor equipment combination while supporting up-flow, down-flow, and horizontal applications.

For additional installation flexibility, the pre-charged coil supports an applicable MRCOOL® No-Vac® Quick Connect® line set or a compatible standard HVAC line set using the manufacturer-approved connection method.

Complete Dual Fuel Heating & Cooling

A dual fuel HVAC system combines an electric heat pump with a gas furnace.

During cooling season, the 36,000 BTU heat pump operates as the home’s central air conditioner.

During heating season, the system can provide heat-pump heating and use the 80,000 BTU gas furnace as the alternate heating source, depending on thermostat settings, outdoor conditions, system configuration, and the selected changeover strategy.

This gives homeowners two heating technologies in one central ducted system rather than relying exclusively on electric resistance heat or a gas furnace.

Proper dual-fuel controls and changeover settings must be configured for the application.
