In 2026, besides new unit sales, the global HVAC retrofit market is experiencing rapid expansion. A large number of aging heating & cooling units in European and North‑American residential, garage and light‑commercial spaces need replacement. However, end‑users resist heavy‑duty reconstruction of walls, wiring and refrigerant pipelines due to high construction cost and long project cycle.

To address this pain point, inverter outdoor units compatible with third‑party indoor units are gaining great popularity among overseas buyers. The system works with most existing third‑party indoor units and 24V thermostats without modifying original wiring or refrigerant lines. Multiple control options including wired controller and Wi‑Fi smart control are available, covering house renovation, garage upgrade and commercial retrofit projects.

For overseas distributors and system integrators, these solutions greatly simplify on‑site installation, shorten construction cycles and cut material waste. End‑users can upgrade HVAC systems with economical investment instead of full‑set replacement.
