Many homeowners clean or change their home’s HVAC filter systems regularly, but of those that do, how many of them schedule a cleaning of their home’s air duct systems? A home’s heating and cooling system tend to accumulate fungi, mold, bacteria, and other contaminants, all of which reduce the home’s indoor air quality. A thorough air duct cleaning removes contaminants from a home’s heating and cooling system.
If a family member begins to experience unusual illnesses or medical problems such as sneezing, runny eyes, irritated mucous membranes, coughing, wheezing, or other respiratory symptoms or allergic-type reactions, it may be a sign of dirty air ducts. The first step is to schedule a consultation with an air duct cleaning professional at A-ableair.com.
Small amounts of dust in the HVAC system are expected and acceptable. However, those suffering from allergies are likely to be more susceptible to amounts that would not affect non-sufferers. If, after a visual inspection, a copious amount of mold or dust is found then scheduling Air Duct Cleaning Services is warranted.
The following are guidelines recommended by the Environmental Protection Agency:
- Mold growth is visible inside the ducts or other HVAC components.
- Evidence of rodents or other pests is found in the ductwork.
- Vents are severely clogged such that air flow is restricted.
Other reasons for cleaning air ducts include:
- Water has entered the system due to flooding, fire, or storm.
- Concerns of residents with allergies.
- Recent renovations. Air duct cleaning prevents the dust from being distributed throughout the air ducts.
Air Duct Cleaning Services clean the ducts using specialized vacuum systems which put the HVAC system under negative pressure. However, the vacuuming alone does not clean the duct work, but rather devices placed into the ductwork that loose the contaminants from the surface. A variety of brushes, air whips, and even skipper balls are used to scrub debris and agitate the inside surface of the air ducts. The loose particles are easily taken up by the vacuum.
The vacuum systems may be truck-mounted or portable units. In general, truck or trailer mounted vacuums are more robust and powerful. Whereas, portable units may be carried inside positioning the unit closer to the ducts. Both types meet the industry standard for cleaning ductwork. Any vacuum system that vents indoor must be equipped with a HEPA filter.
