Leading HVAC manufacturers (Trane, Carrier, and Lennox) announced earnings within days of each other that were similar showing that HVAC demand remains exceptionally strong, commercial markets are robust, data centers are becoming a major growth engine, and the North American replacement cycle remains healthy.

All three companies delivered solid top-line growth and profitability, demonstrating that HVAC end markets remain resilient despite broader economic uncertainty.

The strongest demand across the industry came from non-residential construction and retrofit activity, particularly large commercial buildings, institutional projects, and infrastructure investments. Although commercial markets garnered most of the attention, residential replacement demand also remained healthy.

Rather than seeing slowing demand, the companies discussed record backlogs and strong booking trends. The industry appears to be in the early-to-middle stages of a multi-year growth cycle.

Let’s take a look at all 3 in more detail….

Trane

Trane’s Record Backlog and Bookings Surge Fuel Raised Guidance as Commercial HVAC Boom Trumps Residential Softness

Trane Technologies announced earnings for 3Q 2026 on October 29. Trane delivered another standout quarter, providing strong evidence that the industry is in the midst of a multi-year demand cycle. Trane’s third-quarter 2026 results featured accelerating commercial HVAC growth, strong residential activity, surging bookings, and a record backlog that now stretches well into 2027 and beyond.

Trane reported revenue of $6.76 billion, up 18%, as organic revenue grew 16%. Meanwhile, organic bookings growth of 20%. Trane had a backlog of $12.5 billion, up 73% with an enterprise book-to-bill ratio of 107%.

Notably, orders exceeded revenue across every business segment, a strong indicator that demand remains outpacing production. CEO David Regnery emphasized that Trane’s focus on energy efficiency, sustainability, smart building controls, and advanced HVAC systems continues to align with powerful secular growth trends.

Trane’s Growth Led by Americas

Trane’s Americas segment delivered the strongest results and remains the primary contributor to Trane’s performance as Americas revenue rose 21% to approximately $5.65 billion, with 19% organic growth. Drivers included commercial HVAC, Applied Solutions, strong service revenue, and improved residential HVAC. Americas operating margins expanded 50 basis points to approximately 22.3%, reflecting favorable volume leverage and productivity gains.

Commercial HVAC Was the Driver

Commercial HVAC remains Trane’s largest and most important growth driver. Global Applied bookings increased more than 40%, while Americas Commercial HVAC backlog increased approximately 80% year over year.  Commercial HVAC revenue in the Americas grew in the low-20% range, driven by applied systems, data centers, institutional projects, healthcare facilities, energy-efficiency upgrades and building automation investments.

Most notably, Applied Solutions revenue increased more than 60%, one of the strongest growth rates reported anywhere in industrial HVAC this earnings season.

Services a Growing Part of The Business

One of the less-discussed but increasingly important aspects of the Trane story is services. Management noted that services now account for roughly one-third of total revenue and have delivered a low-teens compound annual growth rate since 2020. Americas service revenue increased approximately 10% during the quarter.

This matters because service revenue generates higher margins and improves earnings stability, creates recurring revenue streams and most importantly, deepens customer relationships. As buildings become smarter and more connected, Trane’s controls, monitoring, and optimization services should become increasingly valuable.

Residential Turning the Corner

Like Carrier, Trane reported stronger residential trends than many investors anticipated. Residential bookings and organic revenue both increased approximately 20% during the quarter. Management specifically noted that residential performance exceeded internal expectations. Unlike 2024 and parts of 2025, when channel inventory adjustments weighed on results, normalized inventories and healthy replacement demand appear to be supporting growth once again.

While Carrier has become the most visible HVAC beneficiary of hyperscale data-center spending, Trane is seeing many of the same trends. Management highlighted a more than 40% growth in global Applied bookings, strong data-center demand resulting in commercial HVAC backlog growth of roughly 80% and record companywide backlog of $12.5 billion.

Importantly, more than $8 billion of backlog is already scheduled for 2027 and beyond, providing unusually strong revenue visibility.

Trane’s Guidance and Concerns

Similar to last quarter, Trane raised revenue guidance following the strong quarter. Management now expects approximately 11% organic revenue growth for 2026 and roughly 13.5% reported revenue growth. For the fourth quarter, Trane expects mid-teens organic revenue growth.

Similar concerns were raised as in other earnings calls this quarter concerning whether commercial growth and data-center demand are sustainable. Management’s response was that demand remains broad-based across multiple sectors and backlog growth supports confidence that demand is not simply a short-term surge.

There were concerns over margin pressures as the company reduced full-year organic leverage expectations to the low-20% range versus an earlier goal of 25% or higher due to component constraints, inflation, timing of pricing realization and supply-chain inefficiencies.

Finally, investors also questioned whether residential demand could weaken if interest rates remain elevated, to which management acknowledged the risk but pointed to healthy replacement demand and normalized channel inventories as positive indicators heading into 2027.

Insights Into the US HVAC Market

Trane’s quarter provides several important signals for HVAC distributors. Commercial HVAC growth significantly outpaced most industrial and construction markets. Large, applied projects, particularly those connected to data centers and energy efficiency, continue to drive distributor demand. Distributors and contractors with service, controls, and recurring-maintenance capabilities are likely to outperform product-only competitors. Data centers are rapidly becoming one of the most important HVAC markets in North America. The strong residential quarter suggests the replacement market remains resilient, a positive signal for distributors that rely heavily on residential contractors.

Carrier

Carrier announced 3Q 2026 earnings on October 29. They delivered one of the strongest quarters in the industrial and building-products sector, posting double-digit sales growth, surging commercial HVAC orders, accelerating data-center demand, and record backlog.

Carrier reported revenue of $6.26 billion, up 12% with organic sales growth of 15%. Adjusted operating profit growth was 33% and adjusted operating margin expanded 260 basis points to 17.4%. Orders grew approximately 35% and Carrier had a record backlog exceeding $8.5 billion.

The biggest story was the performance of Climate Solutions Americas (CSA), which encompasses much of Carrier’s North American HVAC business. CSA sales increased 24% to $3.35 billion, with organic growth of 25%. Orders rose approximately 60%, an extraordinary result for a company of Carrier’s size. Segment operating profit increased 40% to approximately $745 million, while operating margin expanded to 22.2%, up 250 basis points y-o-y.

Residential HVAC was much stronger than expected as residential sales exceeded 30% featuring improved replacement demand and the absence of prior-year channel destocking headwinds. The stronger market conditions than anticipated earlier in the year allowed Carrier to raise its outlook for the North American residential HVAC market to approximately 7.5 million to 8.0 million units, versus prior expectations of fewer than 7 million units.

Commercial HVAC was arguably even stronger as orders increased more than 60% globally, while commercial sales in the Americas increased more than 25%. Key demand drivers included data centers, semiconductor facilities, healthcare projects, institutional construction, commercial retrofit activity, and energy-efficiency upgrades. Carrier’s commercial HVAC platform continues to benefit from its leading position in high-capacity chillers and advanced cooling systems.

The most eye-catching numbers came from Carrier’s data center business. During Q3 data-center orders increased 300%. year-to-date data-center orders exceeded $3 billion, data-center sales exceeded $550 million and full-year 2026 data-center revenue remains on track to reach $2 billion. Carrier also disclosed a new agreement with a hyperscale customer worth more than $3 billion, including significant minimum-volume commitments.

Perhaps most importantly, management highlighted that long-term agreement minimums are not included in reported backlog, suggesting future demand visibility is even stronger than the already-record $8.5 billion backlog indicates.

Tariffs and Inflation Continue to Weigh on Carrier

Despite strong execution, management devoted considerable attention to inflation and tariff pressures. Carrier disclosed a $550 million to $600 million annual input-cost headwind, cost pressure from tariffs, and ongoing commodity and freight inflation.

Management implemented multiple pricing increases during 2026 and indicated additional pricing actions were planned to address anticipated 2027 inflationary pressures.

While favorable pricing and volume more than offset these pressures during Q3, investors remain concerned that additional tariff actions could pressure margins going forward.

Carrier’s Guidance and Concerns

Management raised its outlook and now expects nearly $24 billion in 2026 revenue with approximately 10% organic sales growth. Management also expects double-digit organic sales growth and continued backlog expansion.

During the Q&A, questions similar to other 3Q earnings calls were raised, primarily around the sustainability of data center demand. Management reiterated that data center growth is in the early stages and cited multi-billion-dollar long-term agreements, significant minimum volume commitments, growing backlog, new chiller product introductions and continued strong hyperscale demand.

Analysts questioned whether margins could continue expanding despite hundreds of millions of dollars in input-cost pressure. Management specifically cited over $600 million of productivity savings this year, which will help offset inflationary headwinds.

Regarding residential demand, investors asked whether residential growth over 30% a rebound from prior-year destocking was just, to which management acknowledged that easier comparisons helped, but argued that replacement demand and market fundamentals have strengthened materially.

What it means for US HVAC Distributors

Carrier’s results carry several important implications, mainly that commercial HVAC is accelerating and is  no longer being driven solely by traditional office construction. Healthy data center, semiconductors, healthcare, institutional and other sectors create a larger and more durable demand opportunity for distributors.

Carrier’s stronger residential outlook suggests channel inventories have normalized, and replacement demand remains healthy heading into 2027. That is particularly positive for HVAC distributors dependent on residential replacement activity.

Tariffs and inflation are affecting manufacturers and distributors alike and Carrier’s ability to implement pricing increases indicates that distributors may continue to benefit from price realization despite higher costs.

Finally, the most important takeaway is that HVAC demand is increasingly tied to AI infrastructure. Data centers are becoming one of the highest-growth end markets for HVAC manufacturers and distributors, creating opportunities well beyond traditional residential and commercial construction.

Lennox

Lennox Industries – Commercial Strength Can’t Fully Offset Residential Slump

Lennox announced 3Q 2026 earnings on October 28.

While much of Wall Street remains focused on hyperscale data centers and commercial chiller demand at larger HVAC manufacturers, Lennox International delivered a reminder that the North American HVAC market remains strong across both commercial and residential channels. The company’s third-quarter 2026 results highlighted healthy replacement demand, strong commercial execution, expanding distribution capabilities, and solid pricing discipline despite continuing tariff and inflation pressures.

More importantly, Lennox’s results provide a valuable window into conditions facing U.S. HVAC distributors because of the company’s unique position across residential equipment, commercial HVAC systems, and its company-owned distribution network.

Lennox’s third-quarter performance benefited from strong North American HVAC demand, improved residential replacement activity, robust commercial project execution, price realization, and dealer and distributor network strength.

Like peers Carrier and Trane Technologies, Lennox benefited from a healthier residential market than many investors anticipated entering 2026. At the same time, commercial HVAC demand remained strong amid ongoing investments in institutional facilities, healthcare, education, industrial projects, and data-center-related construction.  The broader HVAC market environment improved materially throughout 2026 as channel inventories normalized, replacement demand recovered, and large-project activity accelerated.

Lennox achieved third quarter revenue of $1.6 billion, 10% growth.  However, segment profit was down 240 basis points, to 20.6%.  Operating margin also declined 320 basis points to 19.8%.  Competitive pricing pressure, tariffs, and inflation hurt profitability, particularly in Home Comfort Solutions (residential) segment.

Lennox operates through two primary business segments:

• Home Comfort Solutions (Residential), about 60% of revenue, had sales of $937 million, UP 3% y-o-y, with organic revenue down 1% and segment profit of $176 million, down 18% and segment margin of 18.7%, down 490 bps.

The quarter showed signs of stabilization after a difficult period for residential HVAC. Demand improved, as two-step distributor channel sales increased 13%, but direct-to-contractor sales declined 6%. Organic sales decline improved from-9% in Q2 to -1% in Q3.  Acquisitions contributed $39 million of revenue and about $6 million of profit but the biggest issue was margin pressure.  Management disclosed that tariffs and inflation created approximately $47 million of cost headwinds and Lennox lowered prices in selected markets to defend and regain share as the company faced much greater than anticipated competitive pricing pressures.

• Building Climate Solutions (Commercial), about 40% of revenue, had sales of $635 million, up 24% year over year, with segment profit $167 million, up 19% and segment margin of 26.2%, down 110 bps.

Management cited strength in commercial HVAC equipment/services, refrigeration, in national accounts, emergency replacement projects and that business development initiatives and capacity investments made over recent years as paying off.

The segment also benefited from acquisitions, which contributed approximately 9% of revenue growth and roughly $13 million of segment profit. Despite inflation and tariffs, Building Climate Solutions maintained a very strong 26.2% operating margin.

Lennox’ Guidance and Concerns

Following Q3, management reduced expectations for 2026 because of residential pricing pressure, tariffs, inflation, and weaker-than-expected margins.  Revenue expectations were lowered from 8% growth to 6% with Home Comfort Solutions segment growth revised downward from 1% to -4%, while guidance for Building Climate Solutions was raised from 20% to 23%.

The greatest analyst concerns was over residential market share loss.  Investors questioned why Home Comfort Solutions margins had deteriorated so sharply, whether Lennox was losing market share and whether aggressive price reductions were working.  Management acknowledged that it implemented targeted pricing actions to defend and regain market share in certain residential channels. Those pricing actions hurt margins in the near term but were viewed as necessary to stabilize competitive positioning.

Analysts repeatedly focused on cost pressure and wanted to understand why Lennox struggled more than some peers.  Management responded that cost increases arrived faster than pricing realization and competitive conditions limited pricing flexibility.  Lennox is implementing additional tariff-mitigation and productivity programs.

Analysts questioned why Building Climate Solutions was strong, while residential struggled.  Management explained that commercial markets remain healthier than residential markets due to commercial replacement demand, services, strong national accounts, and refrigeration projects.

Lennox, A Tale of Two Worlds

The story of Lennox’s Q3 2026 was really two businesses moving in opposite directions. Building Climate Solutions delivered outstanding growth, with revenue up 24% and strong commercial HVAC, refrigeration, and service activity. Meanwhile, Home Comfort Solutions showed improving residential demand, but aggressive competitive pricing and approximately $47 million of tariff and inflation headwinds compressed margins and reduced earnings.

Looking a Trane, Carrier and Lennox Together

Trane, Carrier, and Lennox all delivered a similar message in 3Q 2026: demand remains robust, commercial HVAC is outperforming, data centers are accelerating growth, and order backlogs provide unusually strong visibility into 2027. Taken together, their results suggest the HVAC industry remains one of the strongest end markets in the broader industrial sector, with secular growth drivers increasingly outweighing normal economic cyclicality.
