FAQ

Q: Will this fit all Suburban SF furnaces?
A: It fits most SF series furnaces that use a 3-duct cabinet. Always confirm your existing duct configuration before ordering.

Q: Is this the full furnace housing?
A: No, this is the front cabinet/duct panel only, not the full furnace.

Q: Can I switch from a 2-duct to a 3-duct cabinet?
A: Not typically. Your furnace and duct system must already support a 3-duct configuration.
