When buyers ask AI engines like ChatGPT, Claude, or Perplexity which window replacement company to use, Pella comes up most often, appearing in 50% of relevant AI responses across the engines tracked here. Renewal by Andersen and Window World round out the top three. These three brands dominate AI-generated recommendations well ahead of the remaining 12 companies in this ranking.
The sources AI engines pull from most heavily include google.com, youtube.com, reddit.com, modernize.com, and ecowatch.com. Modernize is a contractor aggregator and lead-generation platform, while ecowatch covers energy-efficient home upgrades. Reddit threads carry real homeowner experiences that AI engines treat as credible third-party validation. Brands that appear consistently across these sources, rather than just their own websites, tend to score higher in AI visibility.
When picking from this list, pay attention to which brands have strong third-party coverage beyond their own marketing. AI engines weight recent reviews, aggregator listings, and forum discussions heavily when forming recommendations. A brand ranked lower here may still be the right choice for your region or window type, but the top-ranked companies have demonstrated broader, more consistent validation across the sources AI engines trust most.
At a glance
What we observed in this categoryauto-generated
Pella leads the window replacement category with a visibility score of 50.0%, more than four times the category average of 12.5%. Renewal by Andersen follows at 37.5%, leaving a 12.5-point gap between first and second place. Below those two, Window World sits at 25.0% and every remaining tracked brand clusters at 12.5% or below. This concentration at the top means two brands capture the majority of AI-generated exposure across this category, while the remaining 13 brands share comparatively little.
A notable divergence exists between visibility and citation across the top brands. Window World holds the third-highest visibility score at 25.0% but carries a citation rate of 0.0%, meaning AI surfaces the brand in responses without linking back to its domain. Renewal by Andersen shows the opposite pattern, with a citation rate of 25.0% against a visibility rate of 37.5%, making it proportionally the most cited brand. Andersen Windows presents the starkest case, showing 0.0% visibility yet a 12.5% citation rate, indicating the AI references it without prominently featuring it.
Google AI Mode is the top engine for every brand in this dataset, confirming that the category's AI visibility landscape is almost entirely shaped by a single engine. The top cited sources anchoring AI responses include google.com, consumerreports.org, reddit.com, and ecowatch.com, alongside home-services-specific platforms such as modernize.com and houzz.com. The presence of youtube.com and reddit.com in the source list suggests AI is drawing on community and video content rather than brand-owned pages alone.

How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
Rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 30 days and refresh this page automatically. How AI search ranking works →
