Heating, Ventilation, and Air Conditioning Systems Cleaning and Sanitizing
The
impact on Public Health and the Economic Costs of dirty and
contaminated Air Conditioning systems is critically important to the
following building professionals:
FACILITY MANAGERS
PHYSICAL PLANT DIRECTORS
MAINTENANCE MANAGERS
ENGINEERING MANAGERS
BUILDING MANAGERS
COMMERCIAL AND INSTITUTIONAL BUILDINGS
HOSPITALS
HOTELS
SCHOOLS

Proper
cleaning and sanitizing of HVAC systems removes allergens like mold and
dust and vastly improves the quality of the air and the environment of
occupants.
The cleaning of a building's Air Conditioning System
(Heating, Ventilating, & Air Conditioning - HVAC) refers to cleaning
various components of a building's forced air HVAC system. The
components of the HVAC system include the following equipment:
Supply air ductwork
Return air ductwork
Grilles, Vents, and Air Diffusers
Heat Exchangers to include Cooling Coils and Heating Coils
Condensate Drain Pans and drain lines
Fan Blades and Fan Housing
Air Handler Unit (AHU), Cabinet Panels and Housing
Exposed Fiberglass Insulation
Variable Air Volume (VAV) cleaning and upgrades
Reheat coils
Vertical Air Shafts
EXCESS MOISTURE:
If
these components of a buildings HVAC system are not properly installed,
maintained and operated they may become contaminated with excess dust
particles, pollen and other debris. When excess moisture is present the
potential for microbiological growth (e.g. mold) is increased and spores
from such growth may be released into the occupied space. Some of these
contaminants may cause allergic reactions or other symptoms in exposed
persons.

DIFFERENTIAL AIR PRESSURE:
When
dirt, dust and debris collect on the hidden or inside components of a
building's HVAC system, air pressure relationships of the building
design change and alter the air flow characteristics of the occupied
space. Air that is supposed to have a positive pressure relative to the
space becomes negative creating a pathway for microorganisms, moisture
and other building contaminants. Cleaning the HVAC system and removing
the accumulated dirt and debris returns the HVAC system to its designed
specifications and allows the building to function properly.

ENERGY COST:
The
restriction of the movement of air across a cooling coil or heating
coil, because of excessive dirt and debris build up, results in a
significant energy cost to the building. The same can be said about
efficiency loss of a fan or blower that has dirt collected on fan
blades. Dirt accumulation prevents the fan blade from efficiently moving
air.
Inside an air conveyance system there are many unseen
impingement points where dirt and debris can accumulate. These
impingement points are turning vanes, dampers, splitters, reheat coils,
Variable Air Volume units and other devices installed to move and direct
air flow. Any obstruction to air flow through a forced air system will
result in a loss of efficiency resulting in higher energy costs.

CLEANING OF HVAC SYSTEMS:
The
best way to ensure the cleaning of an HVAC system is to allow the A/C
cleaning technician to see the surface that is being cleaned; you can't
clean what you can't see is our motto. AIRMAX only uses new, state of
the art cleaning technology - including video and photographic reporting
- that guarantees the performance of our work. Power brushing, air
drive brushes and contact vacuuming all combined with large HEPA
filtered vacuum collectors are used to clean all aspects of any ductwork
system.
