OUR STORY
35 Years of Protecting the Systems
That Matter Most
New Name. Same Team. Sharper Focus.
For more than 35 years, this team has protected the mechanical systems that healthcare and critical facilities depend on — first as Clark Services Group, now as CleanAir Systems Group. The name changed; nothing else did. Same ownership, same management, same technicians.
What hasn't changed is who counts on us. We're the trusted compliance partner to Penn Medicine, Jefferson Health, Temple, CHOP - Children's Hospital of Philadelphia, Virtua Health, Hackensack Meridian Health, Trinity Health, the NSA, the Philadelphia Flyers and 76ers, and Whole Foods — part of the 50+ healthcare and critical facilities we serve across the region. And what hasn't changed is how we earn it: a certified, fully documented process — NADCA, ACR, and IKECA standards, photo documentation and ASHRAE-calibrated reporting on every visit — that has put CleanAir on the INC 5000, the Philadelphia 100, and the Philadelphia Business Journal Fast 50, multiple years running.
The new name reflects what we've become: not a cleaning company, but a compliance partner for the air-side and exhaust systems that can't be allowed to fail. Clark Services Group built the trust. CleanAir Systems Group carries it forward.
WHO WE ARE
We Are Not a Cleaning Company.
That distinction matters. Cleaning contractors show up, spray surfaces, and leave. We manage the hygiene and compliance of mechanical systems that directly affect patient safety, regulatory standing, and energy performance.
Our clients are hospitals, surgery centers, food service operators, and institutional facilities that cannot afford to fail an inspection, compromise air quality, or let deferred maintenance become a liability. They call us because we show up on time, document everything, and treat every system like it matters — because it does.
Every service we provide is built around three principles: compliance, documentation, and reliability.
OUR COMMITMENT
What Makes Us Different
W2 Employees Only
-
No subcontractors. Every technician is a direct employee — background-checked, uniformed, and trained to our standards. When we send a team to your facility, you know exactly who's showing up.
Photo Documentation on Every Visit
-
Every service generates a photo report. Audit-ready. Stored. Available when you need it — whether that's for Joint Commission, your insurer, or your own records.
Compliance-First Scheduling
-
We track your service intervals and schedule proactively. You don't miss a window. Our team knows your regulatory requirements and builds programs around them.
Flexible Hours — Built Around You
-
Days, nights, weekends. We work around your operation — not the other way around. Most of our hospital work happens overnight so units are back online before morning rounds.
One Vendor, Complete Coverage
-
Kitchen exhaust, grease traps, appliances, air handlers, vents and registers — handled by one team with one documentation standard. You manage one relationship instead of five.
