DUBLIN — The United States HVAC equipment market is projected to grow from $28.53 billion in 2025 to $50.5 billion by 2034, according to a new report from ResearchAndMarkets.com. The market is expected to register a compound annual growth rate of 6.55% from 2026 through 2034.

The report identifies residential and commercial construction, aging system replacements, stricter energy-efficiency standards, changing climate conditions, and demand for connected building technologies as key factors supporting market growth.

Technology is also influencing equipment replacement and purchasing decisions. Manufacturers are introducing variable-speed compressors, cold-climate heat pumps, lower-GWP refrigerants, advanced controls, sensors, and Internet of Things-enabled systems.

Connected HVAC platforms can support remote monitoring, predictive maintenance, demand-response participation, and building management system integration. The report says these capabilities are becoming increasingly important for organizations pursuing energy, emissions, and environmental performance targets.

Energy efficiency is another major market driver. Higher electricity prices, time-of-use rates, updated building codes, and minimum seasonal efficiency requirements are encouraging customers to consider higher-efficiency equipment. Utility incentives, demand-response payments, and equipment rebates are also supporting adoption of variable-speed systems, heat pumps, and advanced commercial HVAC technologies.

Refrigerant regulations are influencing equipment development as well. The phasedown of hydrofluorocarbons is prompting manufacturers to adopt alternatives such as R-32 and R-454B across split systems, rooftop units, chillers, and other equipment categories.

State-level building performance standards, including policies in New York and California, are also encouraging electrification and investment in high-efficiency HVAC equipment.

The report identifies rising equipment, labor, installation, and maintenance costs as challenges for the industry. Advanced components, refrigerant transitions, supply-chain pressures, and shortages of qualified technicians can increase total project expenses.

Price-sensitive customers may delay system replacements or choose lower-cost alternatives, creating a need to balance equipment performance, regulatory compliance, and affordability.

Contractors and manufacturers also face varying federal, state, and local requirements covering refrigerants, energy efficiency, emissions, safety, testing, and certification. The report notes that compliance can require investments in engineering, technician training, and dual-product portfolios during technology transitions.

Distribution and service networks are another area of industry development. Manufacturers, distributors, and contractors are investing in inventory management, technical support, digital sales tools, and regional service capabilities.

The report cites the 2026 formation of a national HVAC distribution platform by Averon Group and Fenco Supply, with support from Trinity Hunt Partners. The investment is intended to expand Fenco Supply's presence in the Southeast while maintaining local expertise and customer relationships.

Recent industry developments highlighted in the report include LG's expanded HVAC, water heating, and controls portfolio presented at the 2026 AHR Expo in Las Vegas. The portfolio included heat pumps, electric and tankless water heaters, updated unitary systems, advanced chillers, and smart control technologies.

The report also cites Midea's February 2025 acquisition of ARBONIA Climate and formation of MBT Climate through integration with Clivet. In addition, Carrier Ventures invested in ZutaCore in February 2025 to support direct-to-chip liquid cooling technology for data centers.

California, Texas, New York, and Florida are among the regional markets highlighted in the report. Each market reflects different combinations of construction activity, climate conditions, building requirements, replacement demand, and adoption of efficiency and connected technologies.
