Why You Need To Clean Your Air Ducts Before Turning Your A/C On
Many people have no idea how the HVAC systems in their homes work. All they know is that the unit provides warmth in the winter and helps them stay cool in summer. They give little thought to the fact that this is achieved by pumping warm or cold air into the rooms of the home via ducting. It stands to reason that any dust or other contaminants within the ducting are going to be blown into rooms by that air. Having a professional air duct cleaning service clean the ducting before use prevents this from happening.
HVAC units are always fitted with filters to extract harmful contaminants from the air that is pumped through the ducting. Provided the filters are replaced or cleaned at recommended intervals, they do a very good job at keeping air clean. However, microscopic particles pass effortlessly through filters. These can accumulate in ducting when the system is not being used. Bacteria and mold can grow rapidly in damp, dark places. When the HVAC system is turned on again, the system could be blowing these into the home.
Because ducting is hidden behind the walls, it may be impossible to see any damage that may have occurred. The most common causes of damage are home renovation work and pest intrusion. A professional air duct cleaning service will get rid of any contaminants that have accumulated, and the service may also be able to identify damaged ducting.
Blockages in your ducting reduce the efficiency of your HVAC system. This costs you money because inefficient HVAC systems push energy bills up. By making sure your ducting is clean before you start using your system, you can cut out this unnecessary expense.
Keeping your ducting clean is not just about financial benefits. Dust and mold can cause serious respiratory problems for occupants, especially those who are vulnerable like asthma sufferers, infants and the elderly. Visible mold is easily dealt with, but hidden mold in your ducting system is a bigger problem and is best left to the professionals.
Signs that your ducting may have a problem
If your energy bill rises but your usage has remained the same, the HVAC system could be the culprit. Have your system, including the ducting, checked for problems. If one or more families are suffering from unexplained allergic reactions, with symptoms similar to hay fever, that could be another indication of ducting issues. Foul odors or excessive noise coming from the system could also indicate problems.
