Why Is Periodic HVAC Cleaning Important?

If the HVAC system is not cleaned regularly, it can be the ideal home for:

  • Dust and detritus

  • All kinds of debris

  • Microbial growth such as bacteria, mould, allergens and germs

Irregular cleaning can also cause:

  • Fiberglass insulation damage

  • Coil corrosion

  • Additional system failures - Blower fan failure, drain blockages, belt issues and more

When the air ducts of your HVAC system are cleaned regularly, it can eliminate pollutants from indoor air to a large extent. Regular cleaning can also protect the system from further damage. Moreover, the system efficiency is greatly improved, reducing energy consumption and cost associated. We also offer cleaning attestation certificates after we complete the cleaning service, so that your organization can be recognized as one that has clean air quality.

Sick Building Syndrome (SBS)

In the field of environmental health and health at the work place, this is a syndrome that describes a combination of medical sicknesses or syndromes that cannot be explained and are associated to a building. People can have one or more of the following symptoms:

  • Headaches

  • Shortness of breath

  • Hyper-sensibility and allergies

  • Sinus congestion

  • Irritation and dryness of the eyes, nose, throat and skin

  • Fatigue

  • Coughing and sneezing

  • Dizziness

  • Nausea

Mostly, people experience these symptoms after spending several hours at work. They might feel better after leaving the building for a period of time. The symptoms might also be caused due to the flu or a cold - not necessarily due to poor air quality. However, if most of your employees have the same symptoms, your building could be suffering from SBS.

The types of buildings can suffer from SBS and induce nausea include:

  • Warehouses

  • Offices which may be high rise, low rise and ground floor

  • Retail stores and grocery stores

  • Medical buildings and hospitals

  • Schools such as elementary, secondary, public, private; daycares

  • Seniors homes, long term care facilities, retirement homes

  • Real estate buildings and holdings, high rises, rental properties

  • Townhouses, walk-ups, low rise, homes, condos, lofts

Reasons for Microbial Growth in the Air Duct

If there is moisture in your building ventilation, it often becomes a breeding ground for mould, fungus and Legionella bacteria. The moisture could be caused by either internal or external factors such as:

  • Roof leakage

  • Door gasket failure

  • Condensation pan or drain failure

  • Condensation from AC coils

  • Fresh air intake pulling in rain or snow, or more

Acoustic Insulation Damage

The insulation surrounding the HVAC system can be damaged due to the following reasons:

  • Over time, the insulation becomes dehydrated and lining integrity is compromised

  • A broken belt striking the insulation, which breaks the outer liner and exposes raw fibers to the elements

  • Mechanical repairs performed can disturb existing insulation

Please contact us for recommendations on procedures/corrective actions

Disadvantages of Insulation Damage

Insulation damage can lead to the following problems:

  • The airstream entering through the fan unit can contaminate the ventilation system

  • Acute skin or eye irritation

  • Development of respiratory tract issues

  • Exposure to mould and microbial contaminates

Coil Inspection and Cleaning

A dirty coil is not very efficient and cannot provide proper ventilation. Mould will form first on these coils. This small issue can grow to become a big problem in no time. We use biodegradable cleaners approved by the EPA. It will not corrode or dissolve the fins.
