What is included in commercial HVAC system cleaning?
It covers the entire airside of the system rather than the duct runs alone. That means air handling units and their internal components, evaporator and other coils, blower assemblies and fan sections, supply and return plenums, internally lined surfaces, the duct distribution network, and terminal devices such as diffusers and grilles. In most commercial buildings the air handlers and return side hold the majority of accumulated material, so a duct-only scope leaves the largest reservoirs untouched.
Why duct-only scopes underdeliver
A commercial air handler moves an enormous volume of air across wet coil surfaces. Over years, the AHU cabinet, coil depth, blower section and internally lined surfaces accumulate far more than the duct branches do. Cleaning branches while leaving the AHU fouled produces a system that looks addressed and performs the same.
Internally lined AHUs and duct board
Internal liner in commercial air handlers and duct board systems is common in Florida and it degrades. Where the liner has broken down, cleaning alone gives a short-lived result. Encapsulation or liner replacement is the durable answer, and we scope that honestly rather than cleaning something that will shed again in a season.
Coordination with your mechanical contractor
We clean; we are not your service contractor. Where we find failed components, drainage problems, control issues or capacity problems, we document them and hand them to whoever maintains your equipment. That division keeps everyone honest.

Common questions
How disruptive is this to building operations?
Less than most people expect, because it is planned that way. Work is zoned so only part of the system is offline at a time, and the noisiest and most intrusive stages are scheduled outside occupied hours.
How often should a commercial system be cleaned?
It depends on the building use, occupancy, filtration and the environment. A warehouse and a surgical suite are not on the same interval. An inspection establishes the right cycle for your facility rather than applying a generic number.
Do you clean grease exhaust hoods?
No. Kitchen grease exhaust is a separate specialty with its own standard and certification. We clean non-grease exhaust systems, restroom exhaust and general building ventilation.
