Hitachi at a glance
- Who owns it
- Bosch (Robert Bosch GmbH), through Bosch Home Comfort Group. Bosch agreed in July 2024 to buy Johnson Controls' residential and light commercial HVAC business plus 100% of the Johnson Controls-Hitachi Air Conditioning JV (including Hitachi's 40% stake) for US$8 billion, and completed the deal on July 31, 2025. Bosch uses the Hitachi name under a long-term licence. Some Hitachi-branded North American models (airCore700) are certified to ENERGY STAR by Qingdao Hisense Hitachi Air-conditioning Systems Co. (the Hisense-Hitachi JV).

Warranty
Hitachi didn't publish warranty terms for Canada on any page we could read on October 19, 2026. Get the warranty in writing with your quote.
Strengths and watch-outs
Strengths
- Backed by Bosch Home Comfort Group, which says the 2025 deal took it past 25,000 associates and 33 plants worldwide
- Current US airHome models use R-32 (ENERGY STAR listings with 2026 availability dates)
- ENERGY STAR lists airHome 600, 800 and Multi Pro combinations as cold-climate
Watch-outs
- Ownership changed in 2025: Bosch now runs the business and uses the Hitachi name under licence; confirm who honours the warranty and supplies parts
- 'Hitachi' units come from two platforms (airHome, certified under Johnson Controls; airCore700 and 'Hi UNI', certified by Qingdao Hisense Hitachi), so ask which one a quote covers
- No North American warranty terms could be verified
- R-410A Hitachi 'Hi UNI' models were still ENERGY STAR-listed for the US and Canada in June 2026; confirm the refrigerant
Which rebates Hitachi models fit
23 Hitachi outdoor models meet the cold-climate numbers NRCan publishes for its Eligible Products List (COP of at least 1.8 at −15°C at full output, 70% of rated capacity, a variable-speed compressor) on their ENERGY STAR ratings. That list decides Ontario's Home Renovation Savings rebate, Manitoba's, New Brunswick's, Yukon's and Newfoundland and Labrador's, and the federal National Heat Pump Rebate expected in early 2027. Check the exact pairing on NRCan's list ↗.
23 models meet ENERGY STAR Cold Climate, which earns Quebec's higher LogisVert rate. BC uses its own qualified list. Rebate rules by province:
