Why should you consider cleaning Air Ducts?
Posted on 3:53 am by IRCS
The HVAC (heating, ventilation, and air conditioning) is the technology to maintain indoor environmental comfort. The air ducts are an essential part of the HVAC system, the constant flow of air causes the air ducts to collect dust along its interior surface.
Here are major advantages of regular duct cleaning:
Improved Air Quality:
On an average around 40 pounds of dust is accumulated in air ducts in a normal household per year. A homes normal occupation generates many visible and invisible contaminants that include dust, dander and chemicals. The recirculation process of the ventilation system causes buildup of contaminants in the ducts. This doesn’t mean air duct cleaning must be done daily, but they can hold up a considerable amount of dust in which contaminants may propagate. People who have respiratory health conditions or allergies may find their condition being aggravated due to poorly maintained air ducts.
The first sign of any symptoms of aggravation of respiratory health or conditions that are caused by dust, be sure to inspect the air ducks.
Based on figures provided by the U.S. Department of Energy, around 25-40 % of the energy used in HVAC system is wasted due to dust build up in air ducts. The system has to push harder in order to deliver output when its obstructed and this may cause damage to the system in the long term.
Symptoms to look out for:
- If there are any signs of dust, cobwebs or any noticeable debris blowing out of supply registers
- Mold on the interior surface of ducts
- Insect larva in the duct is a sure sign of impurity in air ducts.
Advantages of Air Duct Cleaning:
- Removes accumulated dust preventing it from circulation in the HVAC system
- Improves the HVAC systems efficiency to up to 40% and saves energy bills in the process
