While most homeowners have their furnace and air conditioning systems checked, cleaned and maintained regularly, often the duct work that runs throughout the home is neglected. These air ducts can collect debris and dust, and do need to be cleaned from time to time. This can be done at the same time as the operating equipment is checked.
The air in your home circulates within the vent system. In colder climates, cool air is directed to the furnace through return vents. It is warmed by the furnace, and returned to the rooms through duct work. Over time, dust, debris and pet hair ad dander can build up in the system. The air quality and air flow can sometimes be improved by having the ducts cleaned.
This process can be especially important for homes that have been recently constructed or have had renovations done as there may be excessive saw dust within the vents. It should also be performed from time to time even if that is not the situation. Keeping the furnace filter clean and changing it regularly can also help to reduce the amount of debris within the ducts and therefore within the home.
Children and pets can sometimes introduce foreign items to the ducts. This can include toys, pens and pencils, and anything else that will fit. If there are a lot of items, or a large item within the vents, it can cause a blockage or allow dust to accumulate around it. This can seriously affect airflow.
When cleaning them, the company you choose will need to cut access panels in the ducts in order to attach vacuum hoses. This is dome near the furnace, usually starting with the intake areas. All of the vent grills will need to be covered to seal up the system and allow for maximum suction.
The most common kind of vacuum system is one mounted on a truck. These have the best suction. When the hose is in place and the vents are covered, the vacuum is started. Most times, the cleaning begins with blowing air into the system to loosen dust and debris. Then, the vacuum can effectively clear out the vents.
Small holes can be made in basement ducts. This allows for the use of tools that are inserted into the holes and help to agitate and direct the debris toward the vacuum system. Following this, the air conditioner coil and the furnace are cleaned, the access holes and other holes made are sealed, and the covers are removed from the grills.
Cleaning furnace and cooling system vents takes a couple of hours. It is a good idea, and while there is no concrete scientific proof that it improves air quality, it can be beneficial, in particular for people that have respiratory problems or allergies. It can also help to reduce the dust that is circulated within the house. If they have not been cleaned in some time, cleaning the air ducts can improve the operating efficiency of the furnace.
