Most of Lennox International’s revenue comes from equipment and supplies for heating and cooling homes in the United States and Canada. It manufactures furnaces, air conditioners and heat pumps for replacing existing systems and equipping new homes. It sells Lennox-branded products directly to independent dealers that install them, including through company-owned Lennox Stores, and sells other brands through distributors. The direct-to-dealer network supplies a substantial share of revenue.
The smaller commercial business sells heating and cooling equipment through contractors and directly to national-account customers. Lennox National Account Services also earns fees for installation, repairs and preventive maintenance. Heatcraft Worldwide Refrigeration sells equipment used to keep food and other perishables cold and to cool industrial applications, through distributors and other commercial buyers. Equipment sales, rather than services, provide most commercial revenue.
Replacement purchases account for a substantial share of sales across both businesses; new construction supplies the balance. Demand depends on weather—hot summers support air-conditioning and refrigeration sales, while cold winters support heating sales—and on construction activity. The company must also adapt its products to applicable refrigerant, energy-efficiency and fossil-fuel heating rules.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
Lennox’s results hinge mainly on North American heating and cooling replacement demand, weather and pricing against rivals including Daikin and privately held Paloma Industries, neither of which appears here.
Carrier competes with Lennox for dealers, contractors and building customers buying residential and commercial heating and cooling equipment. Watch Carrier’s equipment sales separately from parts and service: its business also extends well beyond Lennox’s North American markets.
Trane Technologies competes with Lennox to sell North American households and commercial customers heating and cooling equipment and services. Its residential and commercial HVAC business is the useful comparison, rather than all Americas revenue, which also includes Latin America and transport refrigeration.
AAON competes with Lennox for commercial customers replacing or newly installing rooftop and other comfort-cooling systems, building equipment to customer specifications and selling through independent representatives. Its reported share gains in replacement and owner-controlled projects are worth watching: AAON sells on lifetime cost and performance rather than the lowest upfront price.
Watsco buys Lennox equipment to resell to contractors, but also competes with Lennox Stores to supply them with equipment, parts and installation supplies. Its sales to residential and commercial replacement contractors offer a read on the demand both businesses share from North American equipment replacement, cooling-season weather and new construction.
CSW Industrials competes with Lennox to sell overlapping heating and cooling equipment, installation accessories and service supplies to distributors and contractors. Watch its Contractor Solutions sales of coils, air handlers and installation and service products, where much of the business is seasonal and revenue tends to peak in spring and summer.
Johnson Controls competes with Lennox for commercial customers buying heating and cooling equipment, controls, replacement work and maintenance, but has divested its residential and light-commercial HVAC business. Its repeat maintenance and replacement sales to existing building customers are the relevant signal, not residential equipment demand.
Modine overlaps with Lennox in supplying commercial buildings with heating, cooling and refrigeration-related equipment, but also sells to vehicle manufacturers and specialized data-center markets. Its separate Commercial HVAC segment planned for fiscal 2027 is the closer comparison for Lennox than its vehicle or data-center business.
Lennox depends on Hudson Technologies as its exclusive supplier of certified reclaimed refrigerants for aftermarket support of residential heating and cooling systems. Hudson cleans used or contaminated refrigerant for resale; that supply supports Lennox’s compliance with California requirements for certified reclaimed refrigerant use.
Johnson Controls International plc earningsJCI
Johnson Controls’ report will show whether building owners are still paying to maintain and replace existing equipment, a demand stream relevant to Lennox’s commercial service and replacement business.
Focus on Johnson Controls’ maintenance and replacement business with existing building customers, not its results as a measure of residential equipment demand. Resilient activity would show building owners continuing to maintain installed equipment, a supportive demand backdrop for Lennox’s commercial service and replacement work; weakness would point to pressure on that spending, but would not establish how Lennox’s residential sales are doing.
Watsco, Inc. earningsWSO
Watsco’s sales will show how much equipment replacement contractors are buying through distribution, a channel serving the same market as Lennox.
Look at Watsco’s sales to residential and commercial replacement contractors. Stronger sales would show more equipment moving through distributors to contractors, suggesting firmer demand in a replacement market Lennox also serves; weaker sales would point to cooling demand in that channel. Weather, the cooling season and new construction also affect Watsco, so its sales are not a direct measure of Lennox’s volume.
Lennox International Inc. earningsThis company
Lennox’s report will show whether residential equipment sales can stabilize and whether Building Climate Solutions can sustain its sales and profit growth.
Read Home Comfort Solutions’ sales volume and price and mix alongside its segment profit margin. Rising volume with a steady margin would show dealers and replacement demand supporting the business; weak volume with the margin held up by price and mix would show continued reliance on pricing and product mix; a falling margin too would mean product, freight or other costs are eroding that support. Then compare Building Climate Solutions’ sales with its segment profit: growth in both would show its equipment and service business adding to results, while sales growth without profit growth would point to costs consuming the gain.
Hudson Technologies Inc earningsHDSN
Hudson Technologies’ report will show how its reclaimed-refrigerant business is faring; Lennox relies on it for certified reclaimed refrigerant in residential aftermarket support.
Watch how Hudson Technologies’ reclaimed-refrigerant business performs. Strength would be consistent with a healthier supplier channel; weakness would make the supply channel Lennox relies on for residential aftermarket support a greater concern. Hudson’s report alone cannot establish the quantity or continuity of supply to Lennox, so it is a signal about the supplier’s business, not confirmation of deliveries.
Trane Technologies plc earningsTT
Trane’s residential and commercial HVAC business will show whether North American customers are still buying equipment and services in markets where it competes with Lennox.
Focus on Trane’s residential and commercial HVAC business rather than treating all its Americas results as comparable with Lennox. Resilient activity would show customers in overlapping markets continuing to buy equipment and services, a supportive demand backdrop; weakness would point to softer customer spending. Either result speaks to market conditions, not a change in either company’s market share.
Aaon Inc earningsAAON
AAON’s report will show whether it keeps winning share in commercial replacement and owner-controlled projects, putting pressure on equipment markets it shares with Lennox.
Watch AAON’s share in commercial replacement and owner-controlled projects, particularly for rooftop and other comfort-cooling systems. Further gains would show customers choosing AAON more often in those projects, intensifying direct competition for Lennox’s commercial equipment; stalled or reversed gains would show that pressure is not increasing.
