Bosch unveils residential air-to-air heat pumps

osch Home Comfort Group, a unit of German industrial conglomerate Robert Bosch GmbH, has launched a new portfolio of residential air-source heat pumps for the North American market under its York brand.

The new YD series comprises several efficiency classes, with cooling performance ranging from 15.2 to 20 under the Seasonal Energy Efficiency Ratio 2 (SEER2) rating system and heating efficiency ranging from 8.5 to 10 under the Heating Seasonal Performance Factor 2 (HSPF2) rating system.

According to the manufacturer, the portfolio also includes cold-climate variants capable of maintaining heating performance at outdoor temperatures as low as −25 C.

All models feature fully modulating inverter compressors, allowing the systems to continuously adjust their heating and cooling output according to building demand. Bosch said the technology reduces compressor cycling and associated mechanical stress while improving temperature control and energy efficiency.

The manufacturer said the outdoor units incorporate low-noise fan blades, vibration-isolating mounts and acoustic optimization technology, enabling sound levels as low as 56 dB(A). The systems also feature stainless steel heat exchangers, powder-coated exterior surfaces and optimized fan designs.

The outdoor units measure between 63.3 cm and 84.3 cm in height, with widths and depths ranging from 71.1 cm to 74.0 cm, depending on the model. The manufacturer has not specified unit weights in the publicly accessible product listings.

The new range supports dual-fuel configurations, allowing the heat pumps to operate alongside conventional heating systems, including gas furnaces, depending on climatic conditions and installation requirements.

For system monitoring and control, Bosch has integrated wireless connectivity through its GoTemp Pro mobile application, which provides installers with access to product information, installation documentation and maintenance resources. The heat pumps also support communication with the York Smart Home Control SHC350 thermostat and the GoTemp Home application for residential users.

The heat pumps are designed to operate with the company’s new York JD series indoor air handlers. The factory-matched configurations are intended to simplify equipment selection, installation and commissioning while optimizing overall system performance.

Bosch said the new portfolio is intended to make variable-capacity technology available across a broader range of price and efficiency categories, rather than restricting fully modulating compressors to premium equipment.

All systems are backed by a 10-year limited warranty.

Bosch has not disclosed pricing information or detailed heating capacity and coefficient of performance (COP) data for the individual models in its launch announcement.
