Such performance enhancements are driving market growth and steering the industry towards more adaptive, tech-centric HVAC solutions.
- For instance, IoT-enabled controls, cloud analytics, and AI-driven optimization are redefining how building owners operate HVAC assets. For instance, Johnson Controls’ OpenBlue platform, which integrates occupancy data, grid signals, and weather feeds, delivers additional 5–10% energy savings by continuously refining set-points in real time Johnson Controls. The commercial retrofit segment is benefiting most, as variable-refrigerant-flow systems retrofit easily into existing buildings without extensive ductwork alterations and cut zone-level energy waste by up to 40%.
- Edge analytics are also improving equipment life by optimizing compressor cycling, thereby delaying capital replacement and reinforcing the value proposition of premium, sensor-rich units. Growing familiarity among mechanical contractors, supported by manufacturer training academies, is widening the addressable base and helping to normalize remote-first service contracts.
- As residential and commercial construction surges and aging infrastructure requires retrofitting, the demand for modern HVAC installations intensifies. Energy efficiency is a primary consideration in the design of new buildings, and existing structures are often upgraded to meet increasingly stringent energy guidelines. Urban areas, in particular, are witnessing a pronounced shift towards energy-efficient systems, driven by building codes and market demands that align closely with sustainability objectives.
- For instance, in 2024, the United States saw a resurgence in air conditioner (A/C) shipments, reversing a two-year decline in 2022 and 2023. While total annual shipments typically ranged between 3.5 and 6 million units, exceptions stood out: 2005 recorded a peak of 6.47 million units, and 2021 followed closely with 6.28 million units, as reported by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI).
Commercial sector is expected to Drive the market
- Across the commercial landscape—encompassing office buildings, shopping centers, hotels, and hospitals—new constructions and retrofitting projects are on the rise. Today's commercial real estate is increasingly turning to cutting-edge HVAC solutions, ensuring compliance with the latest energy efficiency standards and building codes. As building owners aim to foster comfortable and healthy environments for their occupants while simultaneously reducing energy expenses, there's been a marked uptick in investments in advanced HVAC systems. With construction spending holding strong, the market is witnessing regular upgrades and system overhauls, driving consistent demand.
- For instance, Federal incentives embedded in the Inflation Reduction Act are front-loading demand for high-efficiency heat pumps, advanced air conditioners, and integrated control solutions. Commercial property owners can accelerate depreciation under the 179D provision, while households qualify for tax credits covering 30% of system costs, capped at USD 2,000 per year.
- Similarly, Heat-pump unit sales are therefore expanding at twice the pace of legacy gas furnaces, aided by state goals such as California’s plan to deploy 6 million heat pumps by 2030 California Energy Commission.
- U.S. shipments of air-source heat pumps in 2024 outpaced those of the previous year, as reported by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI). These shipments have seen a significant uptick, jumping from 1.7 million units in 2012 to 4.33 million units in 2022. A key driver behind this surge is anticipated to be the growth in commercial construction.
- The momentum is magnified by corporate sustainability commitments that demand deeper building decarbonization and by time-of-use tariffs that reward load shifting enabled by connected HVAC platforms. As a result, premium equipment lines that incorporate inverter compressors, adaptive controls, and remote diagnostics command up-front premiums of 15–25% yet still post attractive three- to five-year paybacks when factored against utility savings.
- Younger homebuyers place energy efficiency among their top three criteria, prompting builders to spec two-stage heat pumps and ECM motor air handlers as standard in mid-priced homes. Financing is aided by low-interest green-mortgage products that permit borrowers to roll high-efficiency equipment costs into long-term amortization, smoothing the upfront premium.
