The page that matters for owners: what changed in regulation and pricing, what demand is doing this month, and how your numbers stack up.
Where we are: The A2L transition is fully in force. Since Jan 1, 2026, new residential and light-commercial systems must use low-GWP A2L refrigerants — R-454B or R-32. You can't drop A2L into a legacy R-410A system; the new units use redesigned electricals, spark-proof contactors, and integrated leak-detection sensors.
Headline: Equipment prices are up roughly 15–30% since mid-2025 — driven by tariffs on steel, aluminum, and imported components, the completed A2L transition, and stricter SEER2 minimums. Pre-tariff inventory is exhausted industry-wide, so every unit now carries the full tariff-adjusted cost.
| Manufacturer | Increase | Effective | Notes |
|---|---|---|---|
| Lennox | up to +10% | Feb 16, 2026 | Residential equipment & accessories |
| Carrier | ~+8% | 2026 | Across residential lineup |
| Trane / American Std. | up to +5% | Jan 1, 2026 | Many residential products |
A2L systems also carry a ~5–10% premium over legacy R-410A models (added sensors, spark-free motors, retooled lines).
What to watch: The 2023 SEER2 minimums remain the baseline, with stricter test methodology than the old SEER standard — even an entry-level 2026 system is more advanced than a mid-tier unit from 2020. Combined with the A2L mandate, the floor for what you can legally install keeps rising.
Standards and credits change — confirm specifics with the DOE, the AHRI directory, and your distributor before quoting.
Why it matters: Cooling degree-days are the cleanest leading indicator of call volume. A hotter-than-normal season means equipment runs harder and fails sooner — so staffing and stock should lead demand, not chase it.
| Signal — Summer 2026 | Outlook | Read for contractors |
|---|---|---|
| NOAA Jun–Aug temperature outlook | Above normal, all 50 states | Broad elevated cooling demand |
| Highest-confidence heat | Western U.S. & Plains | Watch for heat-dome spikes |
| ENSO pattern | El Niño strengthening | Supports the warm, dry signal |
