Components Of HVAC System And Air Duct Cleaning

What you need to know starts with the two key components of HVAC and air duct cleaning in San Antonio:

  • Breaking contaminants loose
  • Collection of contaminants

Breaking Contaminants Loose

Properly cleaning HVAC systems requires removing the sources of contamination. Source removal begins with the use of one or more agitation devices designed to loosen contaminants from the surfaces within the heating and air conditioning system. Agitation devices include brushes, air whips and compressed air nozzles or “skipper balls.” Agitation can also be achieved through hand-brushing or contact vacuuming.

Collection Of Contaminants

During cleaning, the entire HVAC system is placed under continuous negative pressure (a vacuum) to prevent the spread of contaminants. Continuous negative pressure allows very fine particles to be removed from the system as they become airborne, ensuring that these particles are not released into the living space when the system is turned on after cleaning. This negative pressure also serves to extract the loosened contaminants, which are collected and removed from your home.

System Access

HVAC system cleaning is not a complex process, but each job is unique. Where possible, access to duct interiors should be made through existing openings such as supply diffusers, return grills, duct end caps and existing service openings. Cleaning technicians may need to cut access holes in the duct work in order to reach inside with various cleaning tools. Creation of these service openings, and their subsequent closure, requires craftsmanship and professional skills.


Equipment Requirements

There is a wide variety of equipment available to HVAC cleaning professionals. Both truck-mounted and portable vacuums can be used to stop the spread of contaminants and get the system cleaned to the NADCA Standard.

Antimicrobial Chemicals

Antimicrobial chemicals include sanitizers, disinfectants and deodorizers that can be applied to nonporous surfaces in HVAC systems to address microbial contamination and help control odors. Only chemicals registered with the United States Environmental Protection Agency (EPA) can be used. These products should only be considered after mechanical surface cleaning has been performed and if the need for such treatment has been deemed necessary. Our team can further discuss the equipment you need to know about for HVAC and air duct cleaning in San Antonio.

Coil Cleaning

Did you know that the coil is half the cost of the air handler? We want to share how to keep the coil clean. After all we do not want to replace your coils. It takes significant time to remove and replace. Most AC companies will try and sell you a whole AC system, making them more money. First, the coils may not be the only problem you have. The plenum is the box that helps supply the air into your home. If it gets moisture due to clogged coils, mold will start growing. If your coils are clogged, your unit starts to work harder and will build up condensation. Give us a call to handle the cleaning of your coils and learn more about what you need to know about HVAC and air duct cleaning in San Antonio.
