Lennox Sets Positive Demand and Backlog Expectations for Q1 2026

Lennox’s expectations for Q1 2026 demand and backlog signals (vs. industry destocking and replacement demand)

1) Demand/backlog signal: destocking has largely concluded; replacement demand is strengthening

Lennox described the industry channel as moving past destocking, stating that “Channel destocking has largely concluded” and that “replacement demand strengthens” as dealers regain confidence. ¹

In addition, for Home Comfort Solutions (HCS), management said distributors “began to restock ahead of the summer season,” which is consistent with channel inventory normalization rather than further destocking. ¹

2) Lennox’s internal replacement-demand indicators: record emergency replacement momentum and early-stage “stabilization”

For Building Climate Solutions (BCS), Lennox emphasized that emergency replacement momentum and disciplined execution drove a “record quarterly performance.” ¹ Management’s framing suggests the company sees replacement activity building momentum in the quarter. ¹

For the customer/conversion dynamic between repair vs. replacement, Lennox highlighted:

• “definitely not getting worse” and “some green shoots” in dealer and consumer confidence returning to more “economic decisions” favoring replacement. ²
• A specific note that contractors were previously constrained (e.g., canister/technical readiness) but are now more confident. ²

This matters for “backlog signals” because Lennox is effectively using confidence and conversion indicators (dealer willingness, consumer decision-making, contractor readiness) as leading signals for replacement-driven demand rather than relying on any explicit backlog number in the excerpts provided. ²

3) What management said about backlog direction in HCS: repair vs. replacement stabilizing + restock as a normal seasonal event

Lennox said repair vs. replacement stabilized and that this stabilization provides “greater visibility into underlying demand trends.” ³

They also addressed a question about whether restocking implies renewed destocking risk, stating:

• “No… We think the restock is pretty normal.” ⁴
• Management is “not concerned” about inventory levels and believes inventory is reaching “normal for the channel and for us.” ⁴

Separately, management explicitly described inventory drawdown as back toward normal seasonality:

• From Q4 to Q1, Lennox built $60 million of inventory this year vs $210 million last year—an approximately $150 million reduction—and characterized this as being “essentially back to a normal seasonal thing.” ⁵
• They also said they reduced production by about 30% in Q1, implying that any absorption effects should roll off later as inventory normalizes. ⁶

Together, these statements indicate Lennox’s “backlog/demand” read is not pointing to worsening channel demand or renewed destocking; instead it points to replacement-driven strength and channel normalization. ¹⁴³⁵⁶

4) Direct demand expectations for Q1 2026: stabilization in HCS and momentum in BCS

Management provided “buzzwords” for the quarter:

• “momentum in BCS and stabilization in HCS.” ⁷

This is the clearest condensed articulation of what they expected demand signals to look like across segments in Q1 2026, with BCS showing replacement momentum and HCS showing stabilization amid weak new construction but improving distributor restocking. ¹⁷

5) Replacement demand and inventory/restock behavior: no pre-buy behavior; inventory levels normal

Regarding potential channel behavior ahead of inflation/tariff events, Lennox said there was:

• “no indication of any prebuy ahead of price increase or inflation.” ⁴
• Inventory replenishment is expected to be “pretty normal” and aligned with the upcoming summer season. ⁴

They also referenced that they use the distinction between “re” (restock/relief) and “de” (destock), stating they believe “restock is good.” ⁴

6) How these demand/backlog expectations show up in Q1 operating reality (supporting evidence)

In Q1, Lennox reported operational demand signals consistent with replacement and normalized channels:

• Home Comfort Solutions: volume supported by improved performance in the 2-step channel and repair vs. replacement stabilizing. ³
• Building Climate Solutions: emergency replacement and national accounts driving volume growth (and contributing to “record quarterly performance”). ³¹
• Lennox also noted that inventory build focused on parts and specific SKUs to support customer fulfillment during peak season, and expected inventory to moderate in the second half. ⁸

While Q1 excerpts don’t include a traditional “backlog” figure, the company is communicating demand/backlog through (a) channel restocking confidence, (b) emergency replacement momentum, and (c) stabilization in replacement conversion dynamics. ¹⁴³²⁷

---

Bottom line (demand + backlog signals for Q1 2026)

• Industry destocking: Largely completed, with dealers regaining confidence and restocking ahead of summer. ¹
• Replacement demand: Management expects/observes strengthening replacement demand, highlighted by emergency replacement momentum and record BCS performance in Q1. ¹
• HCS replacement conversion: Lennox expects stabilization in repair vs. replacement, supported by improving dealer/consumer confidence (“green shoots”) and a view that restocking is normal, not a sign of renewed destocking. ⁷³²⁴
• Net “backlog-like” signal: Rather than indicating falling orders or rising destocking, Lennox’s framework points to inventory normalization plus replacement-driven demand improvement, with inventory behavior aligning with seasonality and fulfillment needs. ¹⁴⁵⁶⁸
