How can a facilities team or HVAC service company use computer vision to check rooftop and outdoor units between visits?

# How can a facilities team or HVAC service company use computer vision to check rooftop and outdoor units between visits?

Technicians or a drone take photos of each unit from set angles on every visit, and a model trained on the company own images compares them. It marks likely issues such as dirty or clogged coils and filters, bent fins, missing or loose panels, damaged insulation on lines, standing water, debris around the unit and rust, and tags each one with the unit ID and a photo. Comparing visits shows which units get dirty fastest, which helps plan cleaning and filter changes by need instead of by calendar, and gives the customer a clear photo record. A service lead reviews the flags and decides what to clean, repair or quote. The model does not replace hands-on checks, gauge readings or safety rules for rooftop work, and people make every repair and safety call.

## What this means in practice

- Start with one site or one customer with many units.
- Label photos from your own units for dirty coils, bent fins, loose panels and debris.
- Take photos from the same angles on every visit.
- Tag each photo with the unit ID.
- Have a service lead review flags before work orders go out.

## How Lid Vizion approaches it

We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.
