    I want to commend Service-Tech technicians for working without a lot of noise, dust, or disruption while cleaning the air ducts. They covered our workstations and other furniture with care. They were definitively focused and thorough in their work.

    Poorly maintained HVAC systems harbor mold, fungi, bacteria, pollen, dust mites and other disease-carrying biological pollutants that are re-circulated through forced-air systems. Given the right conditions of moisture and temperature, these contaminants can flourish in air ducts and be carried out into the work space where humans are exposed.

    Contaminated air ducts contribute to poor indoor air quality (IAQ). The Environmental Protection Agency (EPA) ranks indoor air pollution (also known as sick building syndrome or SBS) among the top five environmental risks to public health. The solution to improving IAQ in your facility is employing the services of a professional air duct cleaning company – one with the experience, technology and equipment needed for proper air duct cleaning.

    Benefits of properly cleaned air ducts/HVAC system

    Complete cleaning of your HVAC system is an important aspect of keeping the system operating at peak efficiency. The National Air Duct Cleaners Association (NADCA) sets the industry standard for HVAC cleaning, and when done correctly, HVAC/air duct cleaning can have many benefits, including:

    • Cleaner, healthier indoor air
    • Lower operational and maintenance costs
    • Energy savings due to improved heating/cooling equipment efficiency
    • Greater work productivity due to fewer illnesses
    • Improved government inspection ratings
    • Cleaner offices, classrooms, facilities and other workplace environments
    • A more professional image with improved environment

    Manual Access Assures Thorough Air Duct Cleaning

    ducts assures thorough cleaning At Service-Tech Corporation, we specialize in guaranteed techniques in air duct cleaning with contact vacuuming and source removal in our air purification process, including the use of high-efficiency particulate air (HEPA) vacuums. While most residential and commercial air duct cleaning companies simply clean as far as they can reach into the ductwork, our certified technicians use manual entry to effectively reach and clean those hard-to-get-at areas within your ducts and HVAC system.

    Air handling equipment, including all fresh air intake and return ducts, heating and cooling coils, and fans are thoroughly washed to purge them of dirt and contaminants. Air diffusers and grilles are thoroughly washed, reset to previous positions, and put back into place.

     

    Access Doors: Where necessary, our technicians can install access doors to ductwork, making it easier to reach and clean all components.

    Sanitizing: For added protection against bacteria, virus, fungus and mold within the HVAC system, we can apply EnviroCON sanitizer to the interior surfaces of the ductwork and air handling equipment. * EPA-registered, EnviroCON is highly effective in preventing contaminants and leaves no toxic residue in the system. *Not available in Michigan

    HVAC Deep Cleaning: Our HVAC deep cleaning cervices work specifically to eliminate viral and bacterial germs that may be harboring in your facilities.

    Our HVAC Deep Cleaning involves:

    • All accessible internal components of the air handling unit are vacuumed-cleaned to remove visible surface contaminants.
    • Coils (heating and evaporator), blowers, blower housings and condensate drain pans are thoroughly cleaned by high pressure washing as needed.
    • All compartments of the air conditioning units are cleaned, including the outside air intake, return air plenum, filter plenum and supply plenum.

    Following the cleaning process, an EPA-registered disinfectant (qualified for use against COVID-19) is applied to the interior surfaces of the air handling unit (AHU) and AHU components. The disinfectant product is applied onto the interior surfaces using a suitable spray or fogging device. 


    Surface Coating:
     Where fiberglass-lined air ducts or duct board are deteriorated or contaminated, a protective coating can be applied to prevent fibers from breaking loose and entering the air flow. Additionally, this coating contains an antimicrobial agent that provides long-term protection against the re-growth of mold and bacteria.

    See how steam cleaning removes the dirt and debris from the cooling coils on this air AHU. After cleaning this AHU, the flow rate across the coils increased by 1200 cfm (cubic feet per minute). This improved its energy efficiency by 78% and reduced the customer’s energy cost by 48%!

    Condenser Coil Cleaning

    Condenser coils fouled with dust, dirt and grime cannot properly supply heat transfer and results in greater energy consumption.
    Cleaning the condenser coils associated with the air conditioner (AC) unit not only helps the unit cool more efficiently, but also reduces the power consumption. When cleaning condenser coils, our technicians vacuum the coils with a soft bristle brush, and utilize a low-volume, low-pressure wash system to thoroughly flush out the coils without damaging the fins. It's important to properly clean the coils in the spring before the heavy demand on the AC unit during the summer. 

    In addition to complete HVAC/air duct cleaning and inspection services, we restore HVAC systems with: 

    • Antimicrobial coatings
    • Surface coatings for deteriorated fiberglass
    • Coating for rusted metal surfaces
    • Drain pan coating
    • Insulation replacement

    As longtime NADCA members we adhere to the NADCA’s ACR (assessment, cleaning, restoration) Standard, the internationally recognized standard for HVAC cleaning and restoration. The ACR Standard establishes minimum performance requirements for:

    • Assessing new and existing HVAC systems
    • Evaluating and verifying the cleanliness of HVAC system components
    • Determining what is needed by way of cleaning and restoration
    • Restoring systems to specific levels of cleanliness

    The ACR Standard also focuses on how to prevent job-related hazards, such as exposure to workers and building occupants, and cross-contamination to the indoor environment.
