The Zacks Building Products - Air Conditioner & Heating industry faces headwinds from housing market volatility, economic uncertainty, and shifting regulations, particularly in Europe and China. Higher interest rates and cautious consumer spending could slow renovation and construction activity, impacting demand. Trade policy risks, including potential tariffs on imports and raw materials, may add cost pressures and disrupt supply chains.

Nonetheless, industry players like Carrier Global Corporation CARR, Comfort Systems USA, Inc. FIX and The AZEK Company Inc. AZEK are poised to benefit from the U.S. administration’s pro-environmental initiatives, supporting demand for energy-efficient solutions. Investments in digitalization, distribution expansion, and strategic acquisitions continue to drive growth, while service-based revenues provide a stable income stream even during market fluctuations. Despite macroeconomic and regulatory challenges, the industry's long-term outlook remains supported by innovation, sustainability trends, and the essential nature of HVAC services across residential, commercial, and industrial markets.

Industry Description

The Zacks Building Products - Air Conditioner & Heating industry comprises designers, manufacturers, and marketers of a broad range of products for heating, ventilation, air conditioning, and refrigeration markets. The products include rooftop units, chillers, air-handling units, condensing units and coils. The industry players also supply thermostats, insulation materials, refrigerants, grills, registers, sheet metal, tools, concrete pads, tape and adhesives. Air conditioning and heating equipment are sold in residential replacement, commercial and industrial HVAC (heating, ventilation and air conditioning), as well as residential new construction markets.

5 Trends Shaping the Future of the Air Conditioner & Heating Industry

Housing Market Volatility & Macroeconomic Uncertainty: The broader housing and remodeling market remains uncertain. Higher interest rates, economic fluctuations, and shifts in consumer spending patterns can impact renovation and construction activity. If homeowners and builders pull back on discretionary projects due to economic concerns, the industry players could face slower growth.

The companies operating in multiple global markets are susceptible to economic and political fluctuations. The European market, particularly in Germany, is facing political and economic uncertainty, affecting demand for residential HVAC solutions. The upcoming elections in Germany and policy changes regarding energy efficiency subsidies could impact consumer confidence and purchasing decisions. Additionally, economic slowdowns in China and fluctuating demand in certain Asian markets present challenges for growth and stability. The residential HVAC segment, particularly in Europe and China, has been navigating through changing regulatory environments and economic headwinds. In Europe, shifts in government subsidies and policies on heat pumps have introduced uncertainty. In China, a struggling property sector and weak demand for light commercial HVAC are concerns.

Tariff and Trade Policy Risks: Many industry players are exposed to potential disruptions from changing trade policies, particularly in the United States and Mexico. With ongoing discussions about increased tariffs on imports from Mexico, any changes could impact production costs and pricing strategies with companies having significant manufacturing operations. Steel and aluminum tariffs also present cost risks. Managing supply chain efficiency while ensuring cost competitiveness in the face of potential tariff increases remains a critical challenge.

Rising Costs, Regulations: Although supply-chain issues have somewhat eased in recent times, the same, along with rising raw material costs, have been causes of concern, hurting the profit margins of industry participants. Operating expenses of companies are increasing due to the sharp rises in variable operating expenses, including company-wide, performance-based compensation, and excessive logistics and freight costs. Meanwhile, the industry is susceptible to stringent governmental regulations on energy efficiency and gas emissions. HVAC systems use refrigerants for cooling, which is harmful to humans and the environment. Also, stiff competition and the impacts of seasonality on the industry’s revenues are significant risks.

U.S. Administration’s Pro-Environmental Moves: Reducing greenhouse gas emissions for a cleaner environmental footprint has been a major focus of the U.S. administration. Many industry participants remain engaged in supporting industries and facilities by selling and maintaining clean and efficient energy systems to reach their environmental goals for carbon reduction while providing resiliency to grid outages. The companies are gaining from the fast-growing controlled-environment agriculture industry courtesy of their consistent supply of clean cooling solutions. Overall, the companies are well-positioned to gain from the renewable energy drive of the pro-environmental U.S. administration.

Technology Augmentation & Inorganic Moves: Persistent investments in technologies designed to revolutionize customer experience seem vital for the industry. Digitization of the companies’ marketplace via e-commerce and iOS/Android-enabled apps, supported by a comprehensive database of product information, continues to see strong momentum. Importantly, new investments in the expansion of distribution, research and development projects, and marketing programs are contributing significantly to the companies’ top lines. The players are also actively pursuing accretive acquisitions to broaden their product portfolios and expand their geographic footprints, as well as market share. Meanwhile, services associated with maintaining, monitoring and repairing the existing equipment are providing industry participants with stable revenue sources. The industry generates a major share of revenues from these services, which consumers generally cannot suspend, even when the construction market fluctuates.

Zacks Industry Rank Indicates Dull Prospects

The Zacks Building Products - Air Conditioner & Heating industry is a seven-stock group within the broader Zacks Construction sector. The industry currently carries a Zacks Industry Rank #156, which places it in the Bottom 37% of more than 250 Zacks industries.

The group’s Zacks Industry Rank, which is basically the average of the Zacks Rank of all the member stocks, indicates bleak near-term prospects. Our research shows that the top 50% of the Zacks-ranked industries outperform the bottom 50% by a factor of more than 2 to 1.

The industry’s positioning in the bottom 50% of the Zacks-ranked industries is a result of a lower earnings outlook for the constituent companies in aggregate. Looking at the aggregate earnings estimate revisions, it appears that analysts are gradually losing confidence in this group’s earnings growth potential. Since December 2024, the industry’s earnings estimates for 2025 have decreased to $5.47 per share (from $5.50).

Despite the industry’s blurred near-term view, we will present a few stocks that one may consider adding to their portfolio. Before that, it’s worth taking a look at the industry’s shareholder returns and current valuation.
