Goodman Downflow Gas Furnaces

Shop Goodman downflow gas furnaces, also called counterflow furnaces, built for homes where the ductwork runs below the furnace. A downflow furnace pulls return air in from the top and pushes warm air out the bottom. That makes it the right choice for slab-on-grade homes, homes with crawlspace or under-floor ductwork, and closet installs on upper floors.

Goodman downflow furnaces come in a range of BTU sizes and efficiency levels, with single-stage, two-stage, and variable-speed options, so you can match your home's heating load and budget.

Why Choose a Goodman Downflow Furnace?
- Designed for down-discharge airflow and below-floor duct systems
- Multiple BTU sizes for homes of every size
- High-efficiency models that help lower heating bills
- Single-stage, two-stage, and variable-speed blower options
- Built with Goodman's reputation for dependable, affordable comfort
- Backed by Goodman's factory warranty when registered

Not Sure If You Need a Downflow Furnace?
Check where your supply duct connects. If warm air leaves from the bottom of your current furnace, you need a downflow model. If it leaves from the top, shop our upflow furnaces instead. Ordering the wrong configuration can mean costly duct changes, so confirm before you buy.
