The Zacks Building Products – Air Conditioner & Heating industry is projected to benefit significantly in 2026, driven by data center growth, increasing demand for energy-efficient cooling systems, and more stringent efficiency standards. Companies are focusing on advanced HVAC solutions, including electric heat pumps, smart controls, and connected systems. Notable industry players such as Comfort Systems USA, Carrier Global Corporation, and SPX Technologies are expanding through acquisitions and enhancing service models, despite facing challenges from housing market weaknesses and cost pressures due to tariffs and inflation.

Key market dynamics indicate that while residential HVAC demand is subdued due to ongoing weakness in single-family construction and cautious consumer spending, commercial demand is surging, particularly driven by AI and data center investments. In 2026, the industry’s earnings estimates have risen, with an overall projection of $5.11 per share, marking a year-over-year increase.

Currently, the industry ranks 32nd out of more than 250 Zacks industries, placing it in the top 13%. The sector has gained 16.7% over the past year, outperforming the broader Zacks Construction sector’s 6.5% increase, although trailing the S&P 500 Composite, which rose by 23.4% in the same timeframe.
