Goodman GMES80 Ultra Low Nox Gas Furnace
The art of precision
Distinctive, Heavy-Duty Heat Exchanger Technology – Constructed from tubular aluminized-steel, the primary heat exchanger is designed for outstanding durability and heat transfer. The use of wrinkle bend technology maintains the wall strength of the tubular design and aids in the efficient transfer of heat.
Multi-Speed ECM Motor Supports Efficiency – A quiet energy efficient blower motor uses the lowest speed it can to help deliver precise temperature control in your home. Lower blower motor speeds require less energy consumption, which can help to lower utility bills, compared to single speed blower motors.
Goodman gas furnaces simply work the way they’re supposed to, making each one a thing of beauty.
Energy-Saving, Multi-Speed ECM Circulator Blower Motor – Provides efficient performance.
Self-Diagnostic Control Board – Silently and consistently monitors the gas furnace to ensure all furnace components are working properly and helps to achieve the energy-efficient performance too. Also, allows for quick troubleshooting when gas furnace needs maintenance.

Who installs the AC unit after I purchase it?
ACDirect does not yet provide installation services directly. However, most of our customers successfully arrange installation through local licensed HVAC contractors. These systems are designed for professional installation and typically include the components your installer will need.
Here’s how it works:
- Hire a licensed HVAC technician in your area
- Use platforms like Angi, Thumbtack, or a local HVAC directory to find reliable professionals
- Confirm your installer is experienced with the system type you’re purchasing
Note:
Please be aware if you choose to install HVAC equipment yourself and don’t possess proper HVAC licensing, you will void the manufacturer’s factory warranty. If you are capable of a factory-compliant installation yourself, you will need a licensed HVAC contractor to sign off on your work, fully confirming factory-compliant workmanship.
