Who makes Honeywell thermostats?
Resideo Technologies does. In October 2018 Honeywell spun off its home comfort and security business as Resideo, a separate public company, which uses the Honeywell Home name under a long-term trademark license.
| Company | What it does in HVAC |
|---|---|
| Resideo (Honeywell Home brand) | Thermostats, zoning panels and dampers, dehumidifiers, ventilation controls, air cleaners and water leak products |
| Solstice Advanced Materials | Refrigerants, including the kind used in newer air conditioners. Spun off from Honeywell in October 2025. |
| Honeywell International | Industrial, aerospace and commercial building technology. No longer in the home thermostat business. |
Resideo said in 2025 that it plans to separate its ADI distribution business as well. The Honeywell Home license stays in place.
