Air Duct Cleaning MN

Minnesota Air Duct Cleaning Air Duct cleaning is an essential part of home maintenance just like mopping and vacuuming. Your duct system is the heart and circulatory of your house. If any of it is gunked up with dust or mold, the core system isn’t going to function properly. Because it’s out of sight, people don’t think about cleaning the system that delivers the air they breathe. Do You Need To Have Your Air Ducts Cleaned For Better Performance? Yes! Air duct cleaning services offers, cleaning the inside of air conditioning and heating ducts using a variety of methods. These include vacuuming, blowing, scrubbing, or treating with chemical compounds that are claimed to kill, seal, or prevent the growth of molds and other organisms. Often claims of better indoor air quality and respiratory health improvements are made by these services. In addition to normal accumulations of dust and dirt found in all homes through regular use, there are several other factors that can increase the need for air duct cleaning: Pets that shed high amounts of hair and dander Occupants with allergies or asthma Cigarette or cigar smoke Water contamination or damage to your home / HVAC system Home renovation or remodeling projects Overall home cleanliness Some occupants are more sensitive to these contaminants than others. Allergy and asthma sufferers, as well as young children and the elderly tend to be more susceptible to the types of poor indoor air quality that air duct cleaning can help to address. Inspect Your Air Ducts You can tell if your heating, ventilation and air conditioning (HVAC) system needs cleaning by one of two ways. First, with a screwdriver, remove a floor or wall register. Then, use a small mirror and flashlight or use a digital camera to take a picture inside the duct. If there is visible dust, dirt or debris, you should have your ducts cleaned. What You Need to Know About Duct Cleaning Air duct cleaning is a misnomer. In actuality, the entire HVAC system should be cleaned. Failure to clean all components of the system can result in re-contamination of the entire system, thus minimizing the benefits of cleaning. Just as you would not only clean half of your living room floor, you also would not want to clean only part of your heating, ventilation and air conditioning (HVAC) system. NADCA recommends cleaning the entire HVAC system, including the following components: Air ducts Coils Drain pan Registers Grills Air plenum Blower motor and assembly Heat exchanger Air Filter Air Cleaner Proper HVAC Cleaning Process There are two key components to HVAC cleaning: breaking contaminants loose, and collection of contaminants. Breaking Contaminants Loose Properly cleaning HVAC systems requires removing the sources of contamination. Source removal begins with use of one or more agitation devices designed to loosen contaminants from the surfaces within the heating and air-conditioning system. Examples of 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 (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.
