MRCOOL Signature 96% AFUE, 70K BTU, 4 Ton, Downflow Gas Furnace - 17.5" Cabinet (MGD96SE070B4XA)

Not only is the MRCOOL® Signature Series Single-Stage 96% AFUE 70K BTU able to provide effective heating for your home in an easy to install downflow configuration, it is also quiet running and energy efficient.

With a 96% AFUE, this unit will help you save on utility bills. This is thanks in part to the multi-speed high efficiency blower motor. You can also experience enhanced cooling SEER ratings when applied with properly matched cooling equipment. You can expect longterm operation thanks to the durable build and finish and an aluminized steel primary heat exchanger with crimped non-welded construction. The aluminized steel inshot burners and durable silicon nitride ignitor help ensure smooth ignition.

You can expect quick whole-home heating with the single stage gas valve. Installation is easy with the unit’s compact 33 inch design with standardized widths for easy coil fit. It can be easily vented with PVC pipe and offers left or right utility connections. It is design certified for direct and non-direct vent applications, and you have the opportunity to transition to liquid propane with an optional LP kit. Maintenance is easy for your HVAC technician courtesy of the easily removable slide out blower design. This furnace is proudly backed by a lifetime heat exchanger warranty and 10 year parts warranty.

What BTU rating should I choose for my air handler?

  • This depends on the coverage area/room size you are trying to heat/cool
  • An Air Handler's BTU is how powerful the fan is. A higher BTU rating will be able to heat/cool a larger area
Air Handler BTU Coverage Area/Room Size (Sq Ft.)*
Up to 375 Sq. ft
12K BTU Up to 500 Sq. ft
18K BTU Up to 750 Sq. ft
24k BTU Up to 1000 Sq. ft
36k BTU  Up to 1500 Sq. ft

*Ceiling height, insulation, and local climate may impact the coverage area. For example, an uninsulated room will require more power than a well insulated room.

Installed and working great

Installed with ceiling cassettes... Quiet and keeping us cool so far !

Thomas R. (Bradford, US)

I had purchase a 2 zone/ 2 head unit.

Installed to manufacture specs and instructions.

One machine lasted 30 days before an internal fan motor- bearing broke and caused product failure.

A week after that, the interior -second head unit failed. Completely iced up internally.

I put a complaint in as soon as each issue presented itself.

I have yet to receive compensation, a replacement part or acknowledgement of the second unit failing.

I do not recommend Mr. Cool products to anyone. They are cheaply made and the customer support is extremely poor.

Not worth DIY savings (pre charged units)

4 ton condensing unit

Very good delivery service installed and works like a Should

walter w. (Port Neches, US)
Old r22 unit, same capacity, worked better in temperature extremes

Product came packaged well, undamaged. Installation was difficult, followed instructions for suction line above coil on bilevel installation with coil above condenser. 108 inside house on startup, 103 ambient. First start, high pressure 500, low pressure 170, supply air temp 66 degrees. Very worried at first, but after house cooed down, everything within parameters. Researched 410a refrigerant, found out it looses efficiency exponentially during temperature extremes. My old r22 unit would supply 54 degree supply air in comparable operating conditions. EPA, government, a/c manufactures all lying to American public
