How AI Search Is Recommending Refrigerator: Monthly Trends

Executive Summary

Whirlpool remains the category leader in September 2026, but its hold is no longer comfortable. Valid recommendation coverage fell from 59.8% in July to 50.1% in September, a 9.7-point decline the benchmark treats as significant. The lead over second-place Bosch narrowed to 0.8 points (50.1% vs. 49.3%), down from a 3.0-point gap in July. Whirlpool's own top-three rate fell 9.0 points from 26.1% to 17.1% across the same span. This is not a quiet month; the category saw six brands post significant baseline-to-current declines.

The broadest finding is a category-wide compression in recommendation coverage. Six tracked brands posted significant declines from July to September: Whirlpool (down 9.7 points to 50.1%), LG (down 9.1 points to 41.0%), Frigidaire (down 8.4 points to 23.4%), Bosch (down 7.5 points to 49.3%), Maytag (down 7.5 points to 23.4%), and KitchenAid (down 11.4 points to 34.9%). No brand posted a significant rise across the three-month series. The August anomalies that saw Sub-Zero and Frigidaire drop to zero coverage resolved in September, with both brands back at measurable levels.

The largest single-month mover was Frigidaire, which rebounded from 0.0% coverage in August to 23.4% in September, a 23.4-point gain that is significant. Sub-Zero similarly returned from 0.0% in August to 32.0% in September, a significant 32.0-point gain. These recoveries indicate the August zeros were month-specific rather than a lasting removal from the recommendation set. The benchmark recorded 475 qualified observations in September, down from 525 in July and 511 in August.

Each monthly run begins with 800 prompt-surface observations (588 unique questions in July; 625 in August; 609 in September) across the benchmark's defined AI/search surface universe. Of those, 800 mentioned a tracked brand or competitor in all three months; 609 were relevant and 191 were irrelevant in July, versus 572 relevant and 228 irrelevant in August, and 567 relevant and 233 irrelevant in September. The public metrics use the 525 qualified observations in July and the 475 qualified observations in September that survive both qualification stages.

Key Findings

Benchmark Context

The report separates the raw collection universe from the qualified analysis set. Brand-level recommendation percentages are calculated within the qualified benchmark set.

These qualified counts are the denominator behind every brand-level percentage that follows. August's funnel (572 relevant, 228 irrelevant, 511 qualified) sits between the two table months.

Benchmark-Level Metrics

The following category-level metrics summarize the overall answer mix before breaking results out by brand.

September's valid recommendation shortlist share fell to 50.9%, the lowest of the three-month series, down from 60.8% in July and 56.6% in August. AI systems produced fewer valid recommendation shortlists in September even as the qualified observation count also declined. The benchmark cannot establish why that ratio moved; it can only describe the shift in the output distribution.

AI Recommendation Trend

The category's coverage leader held in September, but the top tier narrowed as declines spread across six brands.

The category-level change in September came from the combination of several significant downward movements spread across the field, with no brand posting a significant rise. The order at the top held: Whirlpool, Bosch, GE Appliances, LG, and KitchenAid occupy the same relative positions they held in July, though every one of them carries lower coverage. Samsung moved up two positions, passing both Frigidaire and Maytag, and Frigidaire and Maytag now share the same 23.4% coverage figure.

What Changed This Month

Whirlpool

Whirlpool remains the category leader in September, but its position weakened materially. Valid recommendation coverage moved from 59.8% in July to 50.1% in September, a 9.7-point decline the benchmark treats as significant. The sharper story is in the prior month: coverage fell from 56.0% in August to 50.1% in September, a 5.9-point move that sits within normal variation but continues a two-month downward streak.

The quality of Whirlpool's recommendations also slipped. Top-three rate fell 9.0 points from 26.1% in July to 17.1% in September. Rank-one rate moved from 13.0% to 10.9%. Raw mention presence moved from 99.1% in July to 98.5% in September, essentially unchanged, meaning Whirlpool is still named in nearly every relevant response.

The distinction to notice: Whirlpool's presence remains near-universal, but its conversion into top placement has weakened. The brand is still the default mention, less often the default recommendation. Highest-priority diagnostic: which prompt types are driving the top-three decline, and whether specific surfaces are shifting Whirlpool from a leading to a supporting recommendation.

Bosch

Bosch holds second place in September, 0.8 points behind Whirlpool, the narrowest gap of the three-month series. Coverage fell from 56.8% in July to 49.3% in September, a 7.5-point decline the benchmark treats as significant. The prior month saw coverage fall from 53.6% in August to 49.3% in September, a 4.3-point move within normal variation.

Bosch's rank-one rate rose 4.6 points from 9.1% in July to 13.7% in September, the largest movement in rank-one rate among tracked brands this period. Top-three rate moved from 35.4% to 31.6%. Raw mention presence rose from 91.4% to 93.3%.

The distinction to notice: Bosch is winning the first-choice slot more often even as its overall coverage narrows. The brand is being recommended more decisively when it appears. Highest-priority diagnostic: which evidence sources or attributes are driving the rank-one gain, and whether that strength concentrates on particular surfaces.

LG

LG's coverage fell from 50.1% in July to 41.0% in September, a 9.1-point decline the benchmark treats as significant. The prior month moved from 46.6% in August to 41.0% in September, a 5.6-point decline within normal variation, continuing a two-month downward streak.

Rank-one rate fell 4.6 points from 10.3% in July to 5.7% in September. Top-three rate moved from 22.3% to 18.3%. Raw mention presence actually rose from 96.8% to 97.5%, meaning LG is present in nearly every response but is being recommended less often and less prominently.

The distinction to notice: LG's presence is strong and stable, but its position within recommendation shortlists has eroded. The brand is visible without being preferred. Highest-priority diagnostic: which competitor is capturing the rank-one slot LG lost, and whether the decline concentrates in specific comparison prompts.

KitchenAid

KitchenAid posted the largest baseline-to-current decline in the category, falling from 46.3% in July to 34.9% in September, an 11.4-point drop the benchmark treats as significant. The prior month moved from 39.3% in August to 34.9% in September, a 4.4-point decline within normal variation, continuing a two-month downward streak.

KitchenAid's valid recommendation count fell from 243 in July to 166 in September, a drop of 77. Raw mention presence held at 84.8%, down only 0.7 points from 85.5% in July. Top-three rate moved from 10.1% to 8.6%, and rank-one rate from 2.5% to 1.7%.

The distinction to notice: KitchenAid remains a frequently named brand but is being recommended less often overall. Its rank-one rate of 1.7% places it near the bottom of the mid-tier, meaning it is rarely the first choice. Highest-priority diagnostic: which prompt categories are driving the sustained coverage decline, and whether competitors are gaining ground in the same feature-comparison prompts.

Frigidaire

Frigidaire's September result is a significant recovery from an anomalous August. Coverage stood at 31.8% in July, fell to 0.0% in August, and returned to 23.4% in September. The single-month gain of 23.4 points is significant. The valid recommendation count fell from 167 in July to zero in August, then recovered to 111 in September.

The August company list included both "Frigidaire" and a separate flagged entry that recorded zero observations. The clean Frigidaire name returned to measurable coverage in September, indicating the August zero was month-specific rather than a lasting removal. Raw mention presence at 71.0% in September is above its 68.4% July level.

The distinction to notice: Frigidaire is back in the recommendation set but below its July coverage level. Its rank-one rate of 0.2% remains the lowest among brands with meaningful coverage. Highest-priority diagnostic: whether the recovery is spread across surfaces or concentrated in specific prompt types, and whether the brand can convert presence into top placement.

Maytag

Maytag's coverage fell from 30.9% in July to 23.4% in September, a 7.5-point decline the benchmark treats as significant. The prior month moved from 24.9% in August to 23.4% in September, a 1.5-point decline within normal variation. The valid recommendation count fell from 162 in July to 111 in September.

Raw mention presence moved from 60.6% to 58.3%. Top-three rate fell from 7.2% to 4.6%, and rank-one rate from 2.7% to 2.1%. Maytag's coverage now ties Frigidaire at 23.4%, placing both below Samsung.

The distinction to notice: Maytag's decline is steady rather than sudden, spread across presence and placement signals. The brand remains a known name but is slipping toward the lower tier of the recommendation set. Highest-priority diagnostic: which prompt categories are driving the continued erosion, and whether specific feature comparisons are shifting toward competitors.

Sub-Zero

Sub-Zero's September result confirms the August zero was an anomaly. Coverage stood at 36.2% in July, fell to 0.0% in August, and returned to 32.0% in September. The single-month gain of 32.0 points is significant. The valid recommendation count fell from 190 in July to zero in August, then recovered to 152 in September.

The August company list included both "Sub-Zero" and a separate flagged entry that recorded zero observations. The clean Sub-Zero name returned to measurable coverage in September. Raw mention presence at 69.9% in September is above its 65.7% July level. Rank-one rate held steady at 8.6% across July and September.

The distinction to notice: Sub-Zero recovered most of its July coverage in September. Its rank-one rate of 8.6% is the third-highest in the category, behind Bosch and Whirlpool. Highest-priority diagnostic: whether the recovery is consistent across surfaces, and whether the August zero reflected a brand-matching artifact or a genuine one-month absence.

GE Appliances

GE Appliances holds third place in September with 47.4% coverage, down from 53.1% in July. The 5.7-point decline sits within the range the benchmark treats as normal variation, and the prior month's 5.6-point decline was also within normal range. The brand has posted two consecutive months of decline without either move reaching the level the benchmark treats as significant.

Raw mention presence rose from 92.6% to 94.5%. Top-three rate moved from 24.6% to 21.3%, and rank-one rate from 5.1% to 4.4%. GE Appliances remains ahead of LG in the ranking despite both brands declining.

The distinction to notice: GE Appliances is declining more slowly than its immediate competitors, which is why it holds third place. The brand's presence is stable even as its placement softens. Highest-priority diagnostic: whether the downward trend continues into the next month, and which competitor benefits if GE Appliances' coverage keeps narrowing.

Samsung

Samsung's coverage moved from 28.6% in July to 26.7% in September, a 1.9-point decline within normal variation. The brand now sits in 7th place, having passed Frigidaire and Maytag in the ranking. Its top-three rate fell 3.6 points from 9.3% to 5.7%, despite the overall coverage figure holding relatively steady.

Raw mention presence rose from 87.8% to 88.0%, essentially flat. Rank-one rate moved from 2.3% to 1.3%. Samsung's net sentiment score moved from 0.22 to 0.33, though this measures benchmark framing rather than customer sentiment.

The distinction to notice: Samsung's coverage held near its July level while its top-three placement declined this period. Highest-priority diagnostic: which surfaces or prompts are producing the top-three decline, and whether specific competitor comparisons are driving the shift.

Kenmore

Kenmore's coverage fell from 2.3% in July to 0.8% in September, a 1.5-point decline that the benchmark treats as within normal variation given Kenmore's small sample size. The valid recommendation count fell from 12 in July to 4 in September. Raw mention presence moved from 7.6% to 5.9%.

Kenmore recorded zero top-three placements and zero rank-one placements in September. Its 4 valid recommendations place it at the far edge of the recommendation set. The net sentiment score moved from 0.13 to 0.04.

The distinction to notice: Kenmore remains nominally present in the recommendation set but holds no measurable placement strength. Its 0.8% coverage represents a very small count and should be read with caution. Highest-priority diagnostic: whether any prompt category produces consistent Kenmore recommendations, or whether its presence is incidental to mentions rather than intentional recommendation.

Buyer-Intent Interpretation

In July, August, and September, the qualified observations fell entirely within the Brand Recommendation cluster. The comparison and pricing clusters recorded zero observations in all three months, meaning the public benchmark set did not include prompts that asked AI systems to compare brands head-to-head or to assess pricing and value. The benchmark therefore cannot yet answer which brand wins in explicit comparison queries or which brand AI associates with better value. Those questions sit outside the current qualified set and would require a dedicated prompt design to surface.

Brand Opportunity Summary

The benchmark identifies where attention is warranted; a company-level analysis is needed to explain why.

Evidence Behind the Benchmark

The aggregate metrics are built from prompt-level observations (query, surface, recommendation outcome, rank, sentiment, and citations where exposed). Company-level analysis can go deeper into prompt, competitor, surface, and evidence patterns. Source presence is not automatically treated as proof of causation.

Report-Specific Interpretation Notes

• August anomaly resolved: Sub-Zero and Frigidaire both returned to measurable coverage in September after recording zero in August. The August company list included duplicate-looking entries with zero observations; the September list contains only the clean brand names, and both brands recovered most of their July coverage.
• Qualified denominator: All coverage percentages are calculated within the qualified benchmark set (525 observations in July, 475 in September), not the raw collection universe of 800 prompts.
• Small-count movement: Kenmore's coverage of 0.8% represents 4 valid recommendations; movements in this range should be interpreted with caution.
• Directional analysis: Month-over-month movement identifies changes worth investigating; it does not by itself establish the cause of those changes.

Next Step

The Public Benchmark Shows Where a Brand Is Winning or Losing. A Company-Level Audit Shows Why.

The aggregate percentages in this report leave the most important questions unanswered. Which high-intent prompts is a brand actually winning? When a brand loses a recommendation, which competitor takes the slot? What attributes do AI systems associate with each refrigerator option, and which external sources are shaping those answers? A brand-level percentage cannot answer any of these questions on its own.

A company-specific AI visibility audit maps those prompt, surface, competitor, ranking, sentiment, and evidence-source patterns into a prioritized visibility strategy. It turns the benchmark's signals into a concrete set of actions.
