 Product Overview
Dave Lennox Signature® Collection G71MPP Variable-Capacity Gas Furnace
The quietest furnace you can buy1 - and one of the most efficient!
Features
Quiet Operation
- SilentComfort™ technology—delivers the ultimate in quiet, consistent heating—up to nine times quieter than competitive models1
- Variable speed blower motor—ramps up and down slowly so there's no sudden, noisy blast of air at start-up
- Fully insulated cabinet—patented noise-reducing construction further minimizes operating sound to an industry-leading low level
Home Comfort
- Precise Comfort™ technology—automatically adjusts fan speed, heat and airflow capacity in increments as small as 1% for the ultimate in temperature control
- AirFlex™ technology—offers custom settings which can be selected to meet each home's specific year-round comfort requirements
- Zoning-compatible design—works with Lennox' Harmony III™ zoning system to deliver the right amount of comfort for up to four zones
- Secondary heat exchanger—allows the furnace to achieve high efficiency levels by capturing additional heat
- Variable speed blower motor—provides a quiet, consistent flow of air for enhanced temperature and humidity control
- Variable-capacity operation—goes beyond typical low and high two-stage operation, varying output from 40% to 100%
Energy Efficiency
- Efficiency rating of 95% AFUE on all models, all positions—can save you hundreds of dollars each year, compared to standard furnaces
- Energy Star® qualified—meets or exceeds EPA guidelines for energy efficiency
- Variable speed inducers—automatically adjusts to match the system requirements, maintaining balanced combustion and efficiency
- Dual-fuel capability—can be combined with an electric heat pump to enhance comfort and fuel efficiency by alternating between electric and gas heat, optimizing energy use and minimizing heating costs
- This product qualifies for a tax credit under the American Recovery and Reinvestment Act.*
Reliable Performance
- Advanced engineering includes the most innovative features available
- Duralok Plus™ heat exchanger—made of patented ArmorTuf™ steel to ensure high reliability and efficiency
- SureLight® igniter—silicone nitride construction ensures long product life and reliable operation
- SureLight control board—direct-readout diagnostics allow simple, quick troubleshooting
- Limited Lifetime Warranty on heat exchanger
- 10-Year Limited Warranty on covered components
*Not all system combinations apply. Verify actual system efficiency at www.ahridirectory.org and consult your tax expert before claiming energy efficiency tax credits.

Footnotes
- The quietest furnace you can buy (G71MPP)
Based on sound pressure levels during steady-state, high-fire and low-fire operation of Lennox G71MPP-36B-070 and leading competitive units at mid-point temperature rise and minimum external static pressure when set up per Section 4.5.3 of ARI 260.
- The quietest furnace in its class (G60V)
Based on sound pressure levels during steady-state, high-fire operation of Lennox G60UHV-36A-070 and leading competitive units at mid-point temperature rise and minimum external static pressure when set up per Section 4.5.3 of ARI 260.
- The most quiet and efficient central air conditioner and heat pump you can buy (XC21)
A combination of sound ratings established per ARI's test standard: 270; and efficiency ratings established per ARI's test standard: ANSI/ARI 210/240-2005.
- The quietest central air conditioner or heat pump you can buy (XC15/XP15/XPG15)
Air conditioners/heat pumps have sound ratings established per ARI's test standard: ARI 270. Size for size, as a product family, these air conditioners/heat pumps have the lowest published sound ratings of any major U.S. brand of air conditioning/heat pump equipment.
- The quietest and most efficient air handler you can buy (CBX40UHV)
Based on sound pressure levels during operation of CBX40UHV-36 with factory installed MERV16 Precision Pleat™ media filter and leading competitive three-ton units at equivalent static pressure when set up per section 4.5.3 or ARI's test standard. ARI 260-2001; and efficiency (CFM/Watt) ratings established per ARI's test standard: ANSI/ARI 210/240-2005.
