Bosch BOHA-36RTB-M18S Ids Edge Heat Pump 19 SEER2 3 Ton

Product Description

The BOSCH BOHA-36RTB-M18S is a 3-ton, 19 SEER2 inverter-driven ducted split heat pump operating on R-454B refrigerant. Part of the IDS Edge product line, it uses variable-speed inverter technology to deliver efficient heating and cooling across a wide range of outdoor conditions, including cold-climate applications. The compact outdoor unit is designed for residential installations and supports both single-zone and multi-zone configurations. Licensed HVAC technicians install and commission this system, which requires EPA Section 608 certification for refrigerant handling due to its R-454B charge.

The BOHA-36RTB-M18S fits residential retrofit and new construction projects where inverter-based ducted split systems are specified. In single-zone setups, it pairs with IDS Premium air handlers, cased coils, and furnaces from the existing Bosch IDS product family. For multi-zone applications, the inverter platform supports a range of compatible ducted and ductless indoor units, keeping system design and installation manageable. Its compact outdoor footprint makes it suitable for tight installation spaces common in residential retrofit work.

Key Features

• 19 SEER2 efficiency rating for compliance with current federal minimum efficiency standards
• Inverter-driven compressor provides variable-capacity operation for precise temperature control and reduced energy consumption
• R-454B refrigerant — a lower global warming potential alternative to R-410A, future-ready for regulatory transitions
• 3-ton nominal cooling capacity suits typical residential applications
• 59 dBA sound level for quieter outdoor operation
• Compact outdoor platform supports both single-zone and multi-zone configurations

Compatibility

For single-zone installations, the BOHA-36RTB-M18S pairs with existing IDS Premium air handlers, cased coils, and furnaces. For multi-zone applications, the inverter-based platform supports a range of compatible ducted and ductless indoor options within the IDS Edge system family. Verify indoor unit compatibility using Bosch equipment selection documentation before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician holding EPA Section 608 certification, as this system uses R-454B refrigerant, which is classified as mildly flammable (A2L). Disconnect and lock out all electrical power before servicing the outdoor unit or indoor air handler. Follow local mechanical and electrical codes, including applicable sections of the IECC and NEC, for refrigerant line sizing, electrical disconnect requirements, and equipment clearances. Do not substitute refrigerant types — this system is rated exclusively for R-454B.
