HVAC Contractor Monthly Briefing

United States  ·  Presented by Waves Air

The page that matters for owners: what changed in regulation and pricing, what demand is doing this month, and how your numbers stack up.

This month at a glance

The three things worth knowing

  • EPA final rule (effective July 27) lets pre-2025 R-410A units still be installed until existing stock runs out — breathing room for jobs already in the pipeline.
  • Equipment costs are up 15–30% since mid-2025. Lennox +10%, Carrier ~8%, and Trane +5% are in effect, and pre-tariff inventory is gone industry-wide.
  • Hotter-than-normal summer nationwide. NOAA's outlook has above-average temperatures likely across all 50 states — plan for elevated cooling demand.

1 · Refrigerant & Regulation Watch

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.

What changed this month

  • EPA final rule, effective July 27, 2026: R-410A units made or imported before Jan 1, 2025 may still be installed — not just serviced — until existing supplies are depleted. This eases pressure on installs already in the pipeline.
  • Servicing existing R-410A systems stays fully legal for the foreseeable future. Reassure hesitant customers: their current system isn't obsolete.
  • A2L-rated tools are required — manifold gauges, recovery machines, and leak detectors must be A2L-listed. The EPA has $150M in grants supporting A2L safety training and certification.

Owner action items

  • Confirm every tech is A2L-certified and carrying A2L-rated gauges and detectors before the next install.
  • Update your quotes to note refrigerant type and any leak-detection requirements — no surprises at inspection.

2 · Equipment & Parts — Price + Supply

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.

Announced manufacturer increases

ManufacturerIncreaseEffectiveNotes
Lennoxup to +10%Feb 16, 2026Residential equipment & accessories
Carrier~+8%2026Across residential lineup
Trane / American Std.up to +5%Jan 1, 2026Many residential products

A2L systems also carry a ~5–10% premium over legacy R-410A models (added sensors, spark-free motors, retooled lines).

Owner action items

  • Rebuild your good/better/best price book against current landed cost — don't quote off last quarter's numbers.
  • Pre-buy fast-moving SKUs where you have storage, and lock pricing with distributors where you can.

3 · Efficiency Standards & Compliance

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.

  • Confirm regional minimums: the Southeast and Southwest carry higher SEER2 floors for split systems than the North — match equipment to the install region.
  • Check current federal tax-credit eligibility (25C) when quoting high-efficiency upgrades; it's a live selling point for homeowners feeling the price increases.

Standards and credits change — confirm specifics with the DOE, the AHRI directory, and your distributor before quoting.

4 · National Demand & Weather Outlook

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.

NOAA Jun–Aug temperature outlookAbove normal, all 50 statesBroad elevated cooling demand

ENSO patternEl Niño strengtheningSupports the warm, dry signal

What it means for staffing & stock

  • Expect elevated no-cool calls and compressor/capacitor failures through the peak. Keep common capacitors, contactors, and 2–5 ton condensers stocked deep.
  • Book maintenance-plan tune-ups into shoulder windows now to protect emergency capacity when regional heat waves land.

5 · Business Benchmark Ranges

Typical ranges for residential HVAC service businesses, so you can see where you stand. These are industry ranges, not any single company's figures — use them as a gut-check against your own dashboard.
