The Goodman GMVC80 Series furnace is a two-stage, variable-speed natural gas furnace designed for reliable and energy-efficient heating. It features a premium heat exchanger to deliver consistent comfort and energy savings. This unit is R32 NEW REFRIGERANT compliant.
Key features include:
- Energy Efficiency: Operates at 80% AFUE, ensuring 80% of consumed gas directly heats your home.
- Flexible Installation: Supports both upflow and horizontal configurations, suitable for various home layouts including attics and basements.
- Durable Construction: Designed with durable metal flue venting for long-lasting performance.
- Variable Speed Blower: Provides enhanced comfort and quiet operation.
Setup and Installation
Proper installation is crucial for the safe and efficient operation of your furnace. Installation must be performed by a qualified HVAC technician in compliance with all local and state codes, as well as national standards.
Orientation Options
This furnace is designed for flexible installation in either upflow (vertical) or horizontal configurations.

Upflow (Vertical) Installation: In an upflow system, the heat exchanger is positioned at the top of the unit. Cool air is drawn in from the side or bottom, heated, and then released as warm air from the top. This configuration is commonly used in basement installations due to natural convection.

Horizontal Installation: When installing horizontally, typically in attics or crawl spaces, ensure unobstructed airflow from one side to the other. This configuration is versatile and adaptable to airflow in either right or left directions, promoting even heating and preventing cold spots.
LP Conversion Kit (Optional)
This furnace is designed for natural gas. If propane is required, an optional LP conversion kit (LPM-06) is available. Conversion must be performed by a qualified technician.

Operating Instructions
Your Goodman furnace is controlled by a thermostat. For optimal performance and comfort, ensure your thermostat is properly installed and programmed.
Basic Operation
- Power On: Ensure the electrical power switch to the furnace is in the 'ON' position.
- Gas Supply: Verify that the gas supply valve to the furnace is open.
- Thermostat Setting: Set your thermostat to the desired temperature and 'HEAT' mode. For two-stage operation, the thermostat will automatically cycle between stages based on heating demand.
- Fan Operation: The fan can be set to 'AUTO' (runs only when heating) or 'ON' (runs continuously). 'AUTO' is generally recommended for energy efficiency.
If the furnace fails to ignite or operate, refer to the Troubleshooting section or contact a qualified technician.
Maintenance
Regular maintenance is essential to ensure the longevity, efficiency, and safe operation of your furnace. Always disconnect power to the furnace before performing any maintenance.
Filter Replacement
- Inspect the air filter monthly.
- Replace or clean the filter every 1-3 months, or more frequently if you have pets or allergies. A dirty filter restricts airflow, reducing efficiency and potentially damaging the unit.
Annual Professional Inspection
It is highly recommended to have your furnace inspected and serviced annually by a qualified HVAC technician. This inspection typically includes:
- Checking and cleaning the burner assembly.
- Inspecting the heat exchanger for cracks or damage.
- Verifying proper gas pressure and ignition.
- Lubricating moving parts as needed.
- Testing safety controls and electrical connections.
- Checking flue venting for obstructions or leaks.
Troubleshooting
Before calling for service, review these common issues and solutions:
- No Heat:
- Check if the thermostat is set to 'HEAT' and the desired temperature is above the room temperature.
- Ensure the furnace power switch is 'ON'.
- Verify the gas supply valve is open.
- Check your home's circuit breaker for a tripped breaker.
- Insufficient Heat:
- Replace a dirty air filter.
- Ensure all supply and return air vents are open and unobstructed.
- Furnace Cycles On and Off Frequently (Short Cycling):
- Check for a dirty air filter.
- Ensure proper thermostat placement away from heat sources or drafts.
- Unusual Noises:
- Squealing could indicate a worn blower motor belt.
- Rattling might be loose panels or ductwork.
For persistent issues or any concerns regarding gas or electrical components, contact a qualified HVAC technician immediately.
