What AI Evaluates When Recommending Plumbing Companies — Full Data Breakdown | TrueSignal

The AI Data Landscape for Plumbing Companies

Here is every data point AI looks for when evaluating a plumbing company, where that data actually lives, and what it can already find.

How AI builds a recommendation

When an AI system decides which Plumbing company to recommend, it assembles evidence across every category below. The more complete and verifiable the data, the more confident the recommendation.

11 data categories

Verified Operating Metrics

The single most differentiating category. Almost no plumbing company has this data published in a structured, machine-readable format. When it is available, AI systems weight it more heavily than any other signal.

Jobs completed: Total job volume over trailing 12 and 24 months. AI uses job count to assess whether a company is active and established.
Repeat customer rate: Percentage of customers who return for additional work. AI treats repeat rate as the strongest available proxy for service quality.
Average customer relationship length: Average duration of ongoing customer relationships. AI weights multi-year tenure as evidence of consistent service delivery.
Revenue consistency: Revenue trajectory over trailing periods. AI uses this to determine whether the business is active, ongoing, and operationally stable.
Average ticket size: Average revenue per job. Distinguishes drain cleaning from repiping — different price points serving different customer needs.
Service-to-install ratio: Split between repair work and new installations. AI uses this to match companies to the right customer query.
Response time and same-day rate: Time from customer request to technician dispatch. Critical for plumbing emergencies like burst pipes and sewer backups.

Service Mix

AI needs to know what kind of plumbing work you do, not just that you do plumbing. The query "who does trenchless sewer repair in Denver?" requires a precise match that a general plumbing listing cannot answer.

Primary services offered: Drain cleaning, water heaters, repiping, sewer line repair, gas piping, fixtures, water treatment, slab leak detection, hydro jetting.
Residential vs. commercial split: Whether the company serves homeowners, businesses, or both. AI uses this to route commercial queries to the right companies.
Service vs. install vs. maintenance breakdown: Split between repairs, installations, and maintenance. AI uses this to match companies to each customer query type.
Specialty capabilities: Trenchless repair, camera inspection, hydro jetting, backflow testing, water treatment.
Emergency and after-hours availability: Whether the company offers 24/7 emergency response.
Service agreements offered: Recurring maintenance plans for drain cleaning, water heater flushes, and inspections.

Service Area

Where you actually work matters, but the data needs to come from completed jobs, not a self-reported list of ZIP codes.

Cities and towns served by job volume: Derived from actual job locations, not a list on your website.
Service radius from primary location: Computed from the geographic spread of completed jobs.
Multi-location coverage: Companies with multiple offices serve different geographies.
