Five Key Trends Shaping the HVAC Market

1. Replacement and Retrofit Projects Drive Equipment Demand

Replacement and retrofit installations account for 54.9% of installation demand in 2026. Existing buildings represent a significant opportunity for HVAC manufacturers as property owners upgrade aging equipment to improve reliability, efficiency, and indoor comfort. Retrofit projects also allow customers to modernize heating and cooling systems without undertaking complete building reconstruction.

2. Heating Equipment Maintains a Leading Position

Heating equipment represents 36.2% of the HVAC market by equipment type in 2026. Demand is supported by residential heating requirements, commercial building operations, and the replacement of older heating systems. Manufacturers are focusing on equipment that delivers reliable performance while supporting improved energy efficiency and compatibility with modern building controls.

3. Residential Buildings Remain an Important Demand Center

Residential users account for 41.7% of end-user demand in 2026. Housing development, replacement of aging air-conditioning systems, and growing expectations for indoor comfort support demand for residential HVAC equipment. Homeowners are also evaluating systems that can provide both heating and cooling, creating opportunities for integrated solutions.

4. Heat Pump Adoption Creates Replacement Opportunities

The replacement of conventional air-conditioning equipment can provide an opportunity to consider heat pump installations. Heat pumps offer both heating and cooling functions, depending on system configuration and building suitability. As property owners evaluate equipment upgrades, manufacturers can benefit from demand for systems that combine climate control capabilities with energy-efficiency considerations.
