Why heat pumps are still so hot in the US

US heat pump sales have doubled over the past 15 years and, in Q1 2026, have outpaced natural-gas furnaces by 32%, despite the key US heat-pump tax credit ending after 2025. Shipments were flat from December to January but have risen gradually into spring, and the article argues demand appears strong enough to not depend on the tax credit. Overall, the decarbonization transition for building heating is gaining momentum even as policy support sunsets.

Analysis

The important signal here is not that heat pumps are growing; it’s that the market is behaving less like a subsidy-dependent adoption story and more like a durable product-market-fit story. That should support premium multiples for residential HVAC names with heat-pump exposure because investors can stop capitalizing the business as a policy option and start underwrite it as an efficiency-led replacement cycle. The less obvious winner is the installer/distributor layer: if demand is resilient without credits, the bottleneck shifts from consumer incentives to field capacity, which is usually better for pricing and mix than for pure unit growth.

The first-order loser is the gas-heating ecosystem, but the second-order hit is to the political narrative around utility load growth. Electric utilities and grid-equipment vendors still benefit over 6-18 months if electrification persists, but the market may be overestimating how quickly this becomes visible in load factors; the near-term effect is more about incremental winter peak planning than headline kWh growth. For natural-gas utilities with cold-weather exposure, the real risk is not this quarter’s volumes but a slower erosion of residential heating attachments, which compresses long-duration growth assumptions.

Consensus may be missing that the apparent resilience could partly reflect replacement demand and weather-normalized seasonality rather than a fresh acceleration. If that’s right, the right read-through is not a straight-line bull case for the whole HVAC complex, but selective upside for companies with heat-pump share gains and margin discipline. The key falsifier over the next 1-3 months is a deceleration in shipment data once spring normalization is fully complete or weak guidance on orders/backlogs in the next earnings cycle; if that shows up, the post-credit optimism gets repriced quickly.

Key Decisions for Investors

• Long CSASF on any pullback tied to subsidy-expiry fears; take the trade as a 1-3 month continuation bet on demand resilience, with the thesis invalidated if next shipment/booking data rolls over sequentially.
• Preferred expression: long CARR / short LII for 3-6 months, since the market should pay up for the HVAC platform with the cleaner heat-pump mix and penalize the name more exposed to replacement-cycle volatility.
• Add a small basket long of heat-pump beneficiary industrials against gas-heating exposure: long CARR/TT, short a residential gas utility proxy where heating attachment risk is highest; use only if you can source a clean short with meaningful winter-load sensitivity.
• Watch item, not a recommendation: if CARR-style residential HVAC names rally >10% on the article alone without a guidance lift, fade into the move; this is more likely a valuation rerate than a near-term earnings inflection.
• Set an earnings alert for the next 1-2 quarters: if order growth holds while incentives stay absent, that is the confirmation point to add; if backlog or dealer commentary weakens, exit the trade quickly.
