Shopify HVAC & Climate Control Schema — BTU Capacity, SEER2 Efficiency, Refrigerant Type, ENERGY STAR & AHRI Certification Structured Data

Why HVAC Products Are Structurally Invisible to AI Agents

A "12,000 BTU mini-split with inverter compressor ENERGY STAR" is a $500–$3,000 SKU where the purchase decision turns entirely on a stack of technical specifications: BTU capacity relative to room size, SEER2 efficiency rating and what it costs in annual electricity, whether the compressor is a fixed-speed unit that cycles on and off or an inverter that modulates continuously, what refrigerant is inside and whether that refrigerant will be available and affordable for service in five years, and whether the published efficiency numbers are verified by an independent body (AHRI) or unverified manufacturer claims. A shopper asking an AI agent "best air conditioner for 500 sq ft under $600" is relying on the agent to filter and rank products by BTU range, efficiency, price, and certification — none of which are available in Shopify's default schema output.

The gap is compounded by the rapid standards shift in the HVAC category. Since January 1, 2023, new residential HVAC equipment must be rated in SEER2 (not the older SEER standard). Portable AC units must now disclose SACC (Seasonally Adjusted Cooling Capacity) rather than the legacy "as marketed BTU" figure that overstated capacity by 20–30%. Dehumidifier capacity ratings changed from 80°F/60% RH to 65°F/60% RH per updated AHAM standards. Every one of these changes means product pages that haven't been updated to reflect the current standard are either misleading or incomparable — and without structured data encoding the specific standard used, AI agents cannot determine which standard a given rating was measured under.

What Shopify emits by default

Shopify's Dawn theme and most Shopify themes output a Product JSON-LD block with name, description, sku, image, and an Offer block with price, priceCurrency, and availability. For a window air conditioner, this means an AI agent sees: a product name, a price, and whether it's in stock. BTU capacity, SEER2 rating, voltage, AHRI certification, refrigerant type — all absent. The structured data gap between a Shopify HVAC product page and what an AI agent needs to answer a sizing or efficiency query is almost total.

Mini-Split Schema — MRCOOL DIY-12-HP-115 12,000 BTU Ductless Mini-Split

Mini-splits and heat pumps require separate cooling and heating BTU figures, both SEER2 and HSPF2 ratings, compressor type (inverter is standard), refrigerant, voltage, and AHRI certification. The MRCOOL DIY-12-HP-115 is unusual in running on 115V — most mini-splits require 230V — which is a critical purchase decision that structured data must encode explicitly.

SEER2 vs SEER: The Most Important Efficiency Spec Change Since 2023

The DOE's 2023 regional efficiency standards replaced SEER with SEER2 for all new residential HVAC equipment. The change is more than a renaming — SEER2 uses M1 testing conditions with a more realistic external static pressure of 0.5 inches of water column (in H2O) compared to the 0.1 in H2O used for the old SEER rating. The practical result: a unit that would have tested at SEER 16 under the old methodology tests at approximately SEER2 15.2 under the new standard — roughly a 5% reduction in the numeric rating for the same physical equipment.

This matters for Shopify merchants in two ways. First, selling new HVAC products with SEER ratings instead of SEER2 ratings is non-compliant with DOE disclosure requirements for units manufactured after January 1, 2023. Second, comparing a new unit's SEER2 rating against an older unit's SEER rating on a product listing page without explicit labeling of which standard applies will mislead buyers — a 14 SEER2 new unit is approximately equivalent to a 14.7 SEER older unit.

SEER2 Regional Minimums (2023 DOE Standards)

For units still in inventory that predate January 1, 2023 and carry a SEER rating, use name: "SEER Rating (pre-2023 standard)" in the additionalProperty and include the note in the description field. Never publish a SEER value under the name "SEER2" — these are different measurements and the substitution is both technically incorrect and misleading.

HSPF2 and EER2: The Heat Pump and Window AC Equivalents

HSPF2 (Heating Seasonal Performance Factor 2) is the heating-mode analog to SEER2 for heat pumps — it measures heating efficiency across an entire heating season. Like SEER2, it replaced the older HSPF standard using the same M1 test methodology change. A heat pump with HSPF2 10.0 is meaningfully different from one with HSPF2 7.5 — encode this as a separate additionalProperty entry on every heat pump product.

EER2 (Energy Efficiency Ratio 2) applies to window and room air conditioners and measures instantaneous efficiency — cooling output in BTU/hr divided by power input in watts at a single test condition. It is the primary efficiency metric for window ACs because they lack the variable-speed operation that makes seasonal metrics more meaningful. A window AC with EER2 12.0 uses 24% less electricity than one with EER2 9.7 at the same cooling output.

SACC vs BTU for Portable ACs — A Consumer Protection Issue

Before 2019, portable air conditioners were marketed using a "gross BTU" figure that measured cooling output without accounting for the heat the unit itself generates from its motor and the heat that leaks back into the room through the exhaust duct. A unit marketed as "14,000 BTU" might deliver only 9,000–10,000 BTU of net cooling to the room.

The DOE's 2019 portable AC rule mandated SACC (Seasonally Adjusted Cooling Capacity) as the required disclosure metric. SACC accounts for duct heat gain, moisture removal efficiency, and the unit's self-generated heat load. A "14,000 BTU" portable AC under the old method typically rates at approximately 9,000–10,000 SACC BTU under the new standard — a 25–30% reduction in the headline number.

For Shopify merchants: always encode the SACC value, not the old gross BTU, as the coolingCapacityBTU additionalProperty for portable ACs manufactured after 2019. If you have older stock with pre-SACC ratings, label it explicitly: name: "Cooling Capacity (pre-2019 DOE gross BTU — not SACC)". Failing to distinguish SACC from gross BTU in structured data causes AI agents to produce incorrect room-size coverage calculations and misleading comparisons between portable and window units.

}

Refrigerant Type Reference Table

Refrigerant type is increasingly a purchase decision factor for buyers with environmental screening criteria, corporate sustainability commitments, or long-term cost concerns about refrigerant availability and price as phase-outs proceed.

BTU to Coverage Area Sizing Table

The Energy Star sizing guideline is approximately 20 BTU per sq ft (or 1 BTU per 25 sq ft in the direction most sources express it). The table below shows standard and adjusted coverage estimates. Always include the methodology note in structured data — coverage varies substantially with local conditions.

Sizing adjustments: add 10% BTU for south-facing sunny rooms; subtract 10% for heavily shaded rooms; add 600 BTU per additional occupant above 2; add 4,000 BTU for kitchen installations; add 20% for high-humidity climates. These adjustments should appear in the description field of the coverageArea additionalProperty, not the value — the value should be the nominal standard-condition figure so AI agents can filter by it numerically.

AHRI Certification: Why It Is the Most Important HVAC Certification

Unlike UL listing (which certifies electrical safety) or ENERGY STAR (which certifies energy efficiency), AHRI certification verifies that the published performance numbers — BTU cooling capacity, BTU heating capacity, SEER2, and HSPF2 — were independently tested and match what the manufacturer claims. Without AHRI certification, any BTU or SEER2 figure is an unverified manufacturer claim that cannot be trusted for product comparison.

This matters for AI agents because product comparison and recommendation queries require that the underlying numeric specifications are reliable and comparable across products. An AI agent cannot confidently rank a 12,000 BTU SEER2 20 unit against a 12,000 BTU SEER2 22 unit if either rating is an unverified manufacturer claim — the comparison could be completely meaningless. AHRI certification makes the numbers trustworthy.

The AHRI directory at ahridirectory.org is publicly searchable by certificate number. Always include the specific certificate number in certificationIdentification — this is what makes the certification verifiable rather than just a text claim. The AHRI certificate number is typically on the product nameplate and in the installation manual.

Voltage Requirements: Preventing Installation Errors

Voltage type is one of the most consequential purchase specifications for HVAC products. Installing a 230V window AC into a 115V circuit destroys the unit and may cause electrical fire. Purchasing a central AC system without verifying a 240V dedicated circuit is available creates a return scenario and electrician costs. Voltage data that is absent or buried in a product description PDF rather than in structured data causes preventable purchase errors.

The voltage encoding pattern needs to include four pieces of information: nominal voltage (115V or 230V), frequency (60Hz in US/Canada, 50Hz in EU/AU), plug type (NEMA standard), and minimum circuit breaker size. All four belong in the description field of the voltageType additionalProperty — the value should be the human-parseable shorthand ("115V / 60Hz NEMA 5-15" or "230V / 60Hz NEMA 6-20") that AI agents can use for filtering.
