How Heating and Cooling Systems Work
Home central heating and air conditioning units work by blowing warm and cold air through large pipes, called ducts, into all the rooms of a house. While these systems are a great way to achieve a very comfortable and temperature-controlled house, one drawback is that these systems must be thoroughly and professionally cleaned every so often. Otherwise, every time a heating or cooling system is turned on, dirt, germs and allergens circulate through the ducts and into all the rooms of a home.
Air duct cleaning professionals are people trained to thoroughly remove dirt and debris from a home’s air ducts without releasing that dirt and debris into the home. Professionals start by inspecting the ducts to see how dirty they are. They then use a filtered vacuum to clean out the ducts, furnace, coils, and vent covers. In addition to sucking dirt out, professionals also blow compressed air into the ducts to help dislodge any dirt or debris that is attached to duct walls. Once finished, the air ducts, the furnace and all the attached parts should be free of dirt and allergens.
Why Air Duct Cleaning is Important
Dirty air ducts do not just contain dirt; they can also contain bacteria, fungi and mold that can be harmful to people’s health. In fact, according to the National Air Duct Cleaners Association, the air ducts in an average sized six-room home can accumulate 40 pounds of dirt, dust and allergens in a year. This air duct buildup can cause problems such as worsened allergies, poor indoor air quality and decreased air flow through the ducts.
How Often Air Ducts Should Be Cleaned
Air ducts should be cleaned every three to five years on average, but this number can vary widely based on a number of factors. Homes with smokers or pets may need to have the air ducts cleaned more frequently. Air ducts may also need to be cleaned after any major renovations have been completed, as construction can cause dust buildup. While many professional air duct cleaning companies offer free consultations, people can often simply look inside their vents and see how dirty and dusty they look.
Scheduling an Air Duct Cleaning
When it is time for a professional air duct cleaning, people can visit The National Air Duct Cleaners Association’s website to find qualified and certified air duct cleaners in their area. The website lists registered air duct cleaning companies and gives a wealth of information to educate people about the heating and cooling industry.
