Johnson Controls-Hitachi Air Conditioning recently announced the launch of its new portfolio of innovative and environmentally sustainable residential ductless heat pumps utilizing the low-Global Warming Potential (GWP) refrigerant, R-32. The new airHome mini-splits, which feature several cold-climate models, reduce energy use and carbon emissions, and improve reliability, indoor air quality (IAQ), and ease of installation and maintenance.

Johnson Controls Quality

“Johnson Controls-Hitachi is committed to delivering innovative and sustainable HVAC technology that allows homeowners to reduce their environmental impact and improve comfort while providing ample benefits to contractors and distributors that make their job as easy as possible,” said Samuel Vivar, ductless systems product manager, Johnson Controls-Hitachi Air Conditioning. “The durable and reliable airHome mini-split heat pumps have unique features that maximize the life expectancy of the system and make installation and maintenance incredibly efficient.”

Johnson Controls

airHome heat pumps are designed to meet and exceed government regulations set by the American Innovation and Manufacturing (AIM) Act, and they qualify for CEE 25c tax credits and most other local and federal heat pump rebates. R-32 has a GWP rating of 675 – three times less than conventional refrigerants such as R-410A, providing substantial environmental sustainability benefits. The airHome launch continues the momentum of the company’s use of R-32 globally for more than a decade.

Comfort & Efficiency

The ENERGY STAR certified cold-climate airHome 600 and 800 systems are designed to maintain the same level of comfort as a fossil-fuel burning system in harsh winters without sacrificing efficiency or sustainability due to HeatForce technology. A reliable solution even in Northern climates, the systems have a highly efficient heating seasonal performance factor (HSPF2) of up to 11.5 and can operate at 100% capacity as low as -4 F depending on the model with no hard cut-off – meaning they will continue to provide home comfort despite extreme low temperatures.

The airHome line features several high-value features that benefit both the homeowner and contractor, including FrostWashTM, a proprietary self-cleaning technology built into most indoor and outdoor units that traps and freezes accumulated dust and dirt and flushes it away from the coil. This can improve IAQ and preserve airflow capacity while increasing reliability of the systems and reducing maintenance needs. Most airHome models also feature cutting-edge Adaptive Defrost Technology that uses intelligent sensors to continuously monitor and detect coil frosting in real-time. If any frost occurs, the system automatically engages the innovative technology to prevent performance drops, while base pan heaters ensure the defrosted water is completely drawn away from the unit. This maximizes heating performance and further improves efficiency. Another unique benefit of the airHome system is the tool-free access to the high-wall motor and condensate pump compartment which eliminates common pain points for contractors, simplifies installation and maximizes accessibility.

airHome 400

The launch also includes the airHome 400 model which is a more affordable option for less extreme climates and airHome Multi, which features an outdoor unit that can connect to 2-5 indoor units, with each capable of providing individual temperature control for more customized comfort. With a variety of price points, the series is designed to meet the unique needs of different households.
