25,761 raw U.S. mini-split AC price observations across 12 ZIP markets and 29 days.
Mini-Split AC Prices Raw Dataset (2026)
Analyze 25,761 unaggregated product-level listed retail prices for complete mini-split air-conditioning systems across 12 U.S. ZIP markets from July 13 through August 10, 2026. The single analysis-ready CSV preserves titles, dates, geography, package quantities, listed prices, and a source-neutral comparable-price field.
What “raw” means here: unaggregated product-level observations after scope and safety filtering. The file includes derived normalization fields; it is not untouched acquisition data.
Dataset at a glance
A result worth investigating
Listed-price P90 was 2.5× the P10. Across one-unit observations, listed prices ranged from a P10 of $386.99 to a P90 of $949.99, a 2.5× spread. This is a title-level retail distribution, not a claim of product, clinical, installation, or performance equivalence.
What one row represents
One row is one quality-filtered product-title, ZIP-market, date, package-quantity, and listed-price observation. These are listed retail prices—not sales, orders, revenue, demand, inventory, market share, or consumer behavior. Multiple distinct offers can share a title, ZIP, and date; exact duplicate public rows have been removed.
Comparable-price method
The fixed comparison target is 1 complete system. This is one-unit listed-price comparability. It is not installed cost, efficiency, capacity, or performance equivalence. The original package price and quantity remain in every row, so users can audit or replace the provided comparison.
Columns
Project ideas
- Explore listed-price dispersion across system titles
- Track matched mini-split titles through time
- Study cross-market listed-price parity
- Build an HVAC retail dashboard
- Run EDA in Python, R, SQL, Excel, Tableau, or Power BI
- Benchmark missing-value handling without discarding listed-price observations
Quick start with Pandas
import pandas as pd
df = pd.read_csv(
"costinflation-mini-split-ac-retail-prices-raw-2026-07-13-to-2026-08-10.csv",
dtype={"geography_id": "string"},
)
comparable = df.dropna(subset=["normalized_price_amount"]).copy()
print(comparable["normalized_price_amount"].describe())Quality and limitations
- All 348 expected date × ZIP-market combinations are present.
- Exact duplicate public rows: 0. The preparation pass removed 0 byte-identical input repeats.
- Scope review excluded 1 definite out-of-scope or unsafe titles representing 8 input rows.
- Product titles are descriptive text, not stable public product identifiers.
- ZIP labels describe selected markets, not citywide estimates; the panel is not nationally representative.
- Availability and title wording can change unmatched aggregates through assortment change.
- Shipping, tax, redeemed promotions, purchases, and product performance are outside the dataset.
