Construction and remodeling dust can find its way into air ducts. This dirt can contain harmful pollutants such as pet dander, mildew, and mold spores.
These health-harming substances can trigger allergies and respiratory problems in sensitive individuals. Having your air ducts cleaned regularly can keep your family healthy. Duct cleaning is a messy job, so it helps to prepare in advance. Find out more at duct cleaning Coquitlam.
Debris Removal
All kinds of pollutants collect in homes over time, including bacteria, pet dander, skin cells, mold and tobacco smoke. These contaminants are pulled into the HVAC system and recirculated throughout the house five to seven times a day. Over time, this recirculation can lead to a build-up of contaminants in the ductwork.
Duct cleaning involves using large portable or truck-mounted vacuum collection units to suck dust and debris from the duct system. A long brush is also inserted into the ducts and rubbed over the surface to free any stuck or caked on pieces of debris. This is followed by suctioning to remove the debris.
This is called source removal and is the best method for removing debris. It has not been proven to prevent health problems, but it can improve airflow and reduce energy costs. After ducts are cleaned they may be sanitized with chemicals to kill any bacteria and fungus that might be living in the system.
Odor Removal
If you smell a rancid odor that cannot be removed by airing out the house or replacing air filters, it could mean something is amiss inside your home’s duct system. Mold and mildew can thrive in cooling systems, which often collect water from leaky ducts or condensation. If left unchecked, these fungi can spread and create musty odors throughout the home and aggravate allergies, asthma, and other respiratory conditions.
Odors from pet dander or other animals that share your home can also build up in air ducts and disperse throughout the house. Smoke odors can also linger in air ducts even after a home is cleaned of the smoke and other debris caused by fire or flooding.
Rodents like mice sometimes crawl into residential air ducts in an attempt to stay warm and safe during winter. Unfortunately, many of these creatures are unable to escape and die in the ducts. If this is the source of a foul odor, a professional duct cleaning service can locate and remove the carcass as well as any droppings or nests.
Health Benefits
Dust, pet dander and other allergens collect in air ducts. When they get blown around, they circulate throughout the house and aggravate respiratory problems and allergies. Duct cleaning helps to eliminate these contaminants and irritants, supporting health and wellness and improving living comfort.
A thorough duct cleaning also removes musty odors, promoting a fresher indoor environment. It also reduces bacterial and mildew growth, which is harmful to health.
If you have family members with respiratory conditions, such as asthma or allergies, it’s best to have your home’s ductwork cleaned regularly. Dirty ducts can exacerbate their symptoms, causing them discomfort and contributing to other illnesses. Air duct cleaning is especially important after a fire or flood, as contaminated air can cause health issues. Clean ducts can improve indoor air quality, reduce energy bills and extend HVAC equipment lifespan. This is a great option for homeowners that want to avoid expensive repairs or replacements. The cost of professional duct cleaning is minimal when compared to the long-term benefits.
Cost
Duct cleaning can be costly, and it’s important to comparison shop before hiring a contractor. Generally, professionals charge by the square foot to clean both supply and return vents along with registers and the inside surfaces of air handlers.
Some service technicians also add on fees for the number of vents or the entire home. To keep prices low, homeowners should clear the area around their vents and registers before the service begins, and they should replace air filters regularly.
Mold and mildew removal can be particularly expensive, as the spores that cause these substances can grow in the ductwork and recirculate throughout the house. In addition, ducts that are contaminated with rodent waste may need to be sanitized for an additional cost.
In addition to these environmental indicators, a home owner can identify the need for duct cleaning by noting a musty smell coming from the vents. However, it is essential to speak with a physician before deciding whether or not cleaning ducts will improve a family member’s allergies or asthma symptoms.
