Case Study: Large Facility
December 1, 2025
Client: A large facility with over 30 rooftop HVAC units and more than 180 filters to manage.
Challenge:
Quarterly filter changes are required across a complex rooftop system. The sheer number of units and the maintenance logistics create a heavy operational burden — verifying filter sizes, coordinating technicians, scheduling access, and ensuring minimal downtime.
The Solution by Precise Air Filter
Pre-visit Preparation
PAF’s technician first conducted a brief site visit, during which they looked at the rooftop layout, located every air-handler and filter slot, and confirmed filter measurements. This aligns with PAF’s stated service model: “free survey and quote” and “tailored schedule based on the specific application.”
Execution
- On the scheduled day, the technician arrived with 100% correct filter sizes, ready to replace all filters without delay.
- He produced an aerial view of the location plus a detailed description of each air-handler — demonstrating strong preparation, mapping and documentation.
- He completed the full job (180+ filters across 30+ units) in six hours, independently, without hand-holding or assistance.
Outcome & Value
- The client avoided repeated visits or corrections.
- The rapid execution reduced labor time on-site, minimized disruption and likely reduced storage/handling cost of mis-sized filters. This ties directly to PAF’s promise: “reduce energy, storage and labor cost for all our clients.”
- The professionalism of the technician delivered a high-level experience (as the review states: “extremely careful/vigilant…”).
Why It Works
- Precision & documentation: Having the correct sizes ahead of time and a mapped layout lowers risk of mistakes or downtime.
- Speed and minimal management overhead: The client didn’t need to oversee every step — the process was smooth and efficient.
- Service model alignment: Our specialization in commercial/industrial filter replacement (“commercial, industrial & institutional”) and full-service approach (filters + materials + labour) supports this kind of project.
- Credibility: The business boasts an A+ rating from the BBB.
Key Takeaways for Prospective Clients
- If you manage a large facility with many air-handlers/rooftop units, this case shows that a vendor who does the legwork (sizing, mapping, documentation) can save you hours and avoid errors.
- The model “filters + labour + materials” and “tailored schedule” means you don’t have to juggle multiple vendors or worry about filter inventory or replacements.
- Having someone come in, finish the job quickly, and leave you with a documented system means less follow-up and fewer surprises.
