Case Study:
Coffee Regional Medical Center Cuts $48,505 in Electricity After Chemical-Free Coil Cleaning

Client: Coffee Regional Medical Center (CRMC)

Industry: Healthcare

Service Provided: Steam-only, chemical-free HVAC coil cleaning on hospital air-handling units (AHUs) by Green Air EnvironmentalTM, performed in early winter with minimal disruption to operations.

Key Outcomes

  • $48,505 lower electric spend (Jan–May YOY), verified against utility bills.
  • One chiller instead of two needed from April onward (historically, two were required starting in April).
  • Fast payback: savings exceeded the cleaning investment within months.
  • Zero hassle: professional crew, minimal disruption, and no cleanup required.

The Challenge

Fouled AHU coils were restricting airflow and heat transfer, increasing fan and chiller load. Historically, the plant needed two chillers by April to maintain comfort, driving up the hospital’s largest electric consumer.

The Solution

Green Air EnvironmentalTM conducted steam-only, non-toxic coil cleaning across the hospital’s AHUs in early winter 2015. The method re-opens coil fin passages and restores heat-transfer surfaces without chemicals, avoiding residue, hazardous waste, or patient-area risk. Work was completed with minimal disruption to building operations.

Measurement & Verification Approach

Utility-bill normalization

Facility compared electric bills to previous year bills (month-by-month) to confirm savings.

Plant-operation check

Documented that only one chiller was required through spring, versus the historical two-chiller operation starting in April.

Billing data source

Hospital electric cost records support the savings figure.

Results

GA Case study Results Coffee Regional Medical Center

  • Electric cost reduction: Summing Jan–May total electric costs ($253,102.75) and comparing to the previous year Jan–May ($204,597.25) yields $48,505.50 in savings.

  • Chiller runtime avoided: Remaining on one chiller past April lowered the hospital’s biggest electric load while maintaining occupant comfort.

  • Operational quality: Facilities praised Green Air’s professionalism, noting minimal disruption and no post-work cleanup.
