The client, an engineering firm with 120 employees in South Tulsa, reported a 35% increase in absenteeism during fall and spring. The recurring complaint: "allergies" and "respiratory issues."
Initial assessment
During our free on-site walkthrough, we identified three critical issues:
- Carpets with high allergen load: No deep extraction in 3 years. Vacuuming alone wasn't removing embedded particles.
- Clogged HVAC diffusers: Dust buildup on vents was recirculating contaminants every time the system ran.
- High humidity in breakroom: Poor ventilation created conditions for mold growth.
The previous service only performed surface cleaning. Carpet dust load measured 3.2g/m² — commercial standard is below 0.5g/m². Employees were literally breathing construction-era dust.
Solution implemented
- Deep carpet cleaning: Hot water extraction with anti-allergen pre-spray. All 15,000 sq ft treated over a weekend.
- HVAC vent and diffuser cleaning: Removed years of accumulated dust from all supply and return registers.
- Humidity control: Repaired breakroom exhaust fan and implemented daily moisture wipe-down protocol.
- Monthly preventive maintenance: Ongoing carpet spotting, vent inspections, and high-touch disinfection.

Why this matters
Indoor air quality directly impacts productivity. The EPA estimates that poor IAQ can reduce employee performance by 6-9%. In this case, the ROI of deep cleaning was recovered in under 4 months through reduced absenteeism alone.
