Matching and electric heat
Pair this air handler with a Rheem outdoor unit listed for it in the AHRI directory to get certified efficiency. It ships with a factory-installed electric heater.
Installation
The air handler needs its own electrical circuit sized for the blower and any electric heat, a condensate drain with a trap, and a properly sized return and filter. R-454B systems require installation by a licensed HVAC technician following Rheem's A2L procedures.
