Residential Air Duct Cleaning
Your home's air quality is important, and a freshly cleaned system will run more efficiently than a dirty one, which will result in lower utility bills and a much cleaner, healthier home. Dust, dirt, pollen, animal dander and other airborne contaminants can be pulled into your HVAC system every time the furnace or air conditioner runs. The problem is that, over time, particulates such as these can build up inside your ductwork, making your system a potential breeding ground for bacteria, fungus, mildew and even molds. These contaminants are then re-circulated through your home, impacting the health and comfort of your family.
Those who suffer from allergies, asthma or other respiratory ailments — especially children and the elderly — may be vulnerable to the effects of indoor air pollution.
Consider having your ducts cleaned if you:
- Live in a newly constructed home
- Live in an existing house that has been remodeled or recently had construction (where there is often dust and debris)
- Purchased a home and don't know if the ducts have ever been cleaned
- Have lived in your home for more than 10 years and have never had the ducts cleaned
- Have ducts that are contaminated with mold, vermin, feces or insects
- Have ducts that are clogged with excessive amounts of dust and debris and/or particles that are actually visibly released into the home from your supply registers
Air Duct Cleaning by ServiceMaster
If you choose ServiceMaster Rapid Response to clean your HVAC system, we will do so in the following manner:
- First, we'll remove all vent covers (including the return) and thoroughly clean them and put them back in place. The most effective way to clean air ducts and ventilation systems is to employ Source Removal methods of cleaning. This requires ServiceMaster to place the HVAC system under negative pressure through the use of a special high powered vacuum utilizing High Efficiency Particulate Air Filters, which are capable of removing over 99.97% of airborne contaminants down to the size of .3 microns. To put this into perspective, the period at the end of this sentence is over 397 microns wide. This HEPA filtration system is able to remove smoke, dust, viruses, bacteria and fumes, all of which are invisible to the human eye. In order for the vacuum to create negative air pressure on the system, an access hole is cut into the return side of the HVAC.
- The vacuum is then connected using a connection collar, and the vacuum is turned on. While the vacuum draws air through the system, powerful agitating devices (combined with positive air pressure) are inserted into the ducts to dislodge any debris that might be stuck to interior surfaces. This method forces debris down the ducts to the vacuum, where the HEPA filter removes them from your home's ducts.
This push/pull cleaning technique is the most effective removal method currently available in the industry, and is the ONLY method approved by the National Air Duct Cleaning Association. After the entire ductwork has been cleaned, the ductwork can then be sanitized (if necessary), and the furnace can be air washed or otherwise cleaned as recommended.
