Before you decide whether you should have your air ducts cleaned, you need to know a little about how they work and why they accumulate dirt. Visit her website and see what uniqairz air duct can do for you
Most homes are heated with a furnace and a duct system that distributes warm air to the various rooms. This system consists of both return air ducts, which send cold air into the furnace, and supply air ducts, which distribute warm air throughout the house.
Air Duct Cleaning
You can easily tell the difference between return air and supply air ducts by going into the basement and examining the sheet metal ducts that usually hang from the floor joists on the ceiling.
The return duct is usually a large rectangle attached to the bottom of the furnace, while the supply duct comes out the top of the furnace. The supply duct usually consists of a large “main duct” on the ceiling and smaller metal ducts branching off into each heated space. They are often covered by a metal grille on the floor or wall.
Because the ventilation ducts are open to the air in the room, dust, hair, pet dander and other contaminants can easily collect there. This is especially true of the return air ducts that direct air into the furnace.
But does this mean you should have your ducts cleaned?
A good duct cleaning will help remove dust, dirt and hair as well as toys, pens or jewelry that may have fallen into the ducts. Some believe that air duct cleaning improves indoor air quality, as ducts should be sparkling clean after a thorough cleaning, while others say it has little impact on air quality.
Research from the Canadian Mortgage and Housing Corporation has found that replacing the filter on your furnace can help keep the air in your ducts clean and keep the components of your heating, ventilation and air conditioning (HVAC) system from accumulating new dirt. However, it won’t prevent dust from accumulating in your home.
Another reason to consider duct cleaning is if you suspect water has entered the ducts, either through a leak or condensation. This can cause mold to form in the ducts, which can be harmful. You’ll need to fix the leak or condensation problem and then have your ducts thoroughly disinfected – or even replaced, depending on how severe your mold problem has become.
New homeowners or people who have recently renovated should also have their air ducts cleaned if they suspect that the contractors who worked on their home didn’t clean up well. Sometimes construction workers allow small particles of fiberglass, drywall and sawdust to build up in the air ducts.
Air Ducts Cleaned
You should also consider having your air ducts cleaned if you suspect that the airflow to your furnace is being affected by a blockage. Before you spend a lot of money replacing your furnace, you should first have the air ducts inspected and cleaned along with your furnace and air conditioner.
You can clean the ducts yourself, especially the return duct, which is quite large and often collects more dust than the supply ducts. To clean the return duct, first remove the grille on the outside of the duct and then vacuum up the debris with a vacuum cleaner.
However, if you feel that debris in your ducts is affecting air quality, causing mold growth, or blocking airflow to your furnace, you should hire a reputable duct cleaning service. Make sure the service provider is a member of a trade association or works with a reputable heating, ventilation and air conditioning (HVAC) company before hiring them.
