Air Duct & Dryer Vent Cleaning

Heating, ventilation, and air conditioning (HVAC) systems have been shown to act as a collection source for a variety of contaminants that have the potential to affect health, such as mold, fungi, bacteria, and very small particles of dust. The removal of such contaminants from the air duct system and home should be considered as one component in an overall plan to improve indoor air quality.

Research by the U.S. EPA has demonstrated that air duct cleaning may allow systems to run more efficiently by removing debris from sensitive mechanical components. Clean, efficient systems have a longer life span, are less likely to break down, and generally operate more effectively than dirty systems.

The amount of time it takes to clean a residential HVAC system depends on many variables such as the size of the home, the number of systems, the extent of the contamination and the number of HVAC cleaners performing the job. Ask at least two contractors to inspect your system and give you a time estimate for your particular system. This will give you a general idea of how long the job should take as well as an idea of how thoroughly the contractor plans to do the job.

Long and Son recommends regular Air Duct Cleaning for a residential home or business every 2-5 years, with air handler cleaning every year. These recommendations depend on the size of the HVAC system, age of the home and system, the amount of people and pets living in the space and whether occupants suffer from asthma or allergies. For older homes, homes with pets, or occupants with asthma or allergies, you should consider more frequent cleaning intervals.

No. Absolutely no dust will be left in the house after our technicians leave. Because of the powerful negative pressure generated during the service, the HEPA filter collects the dust rather than it being blown back into the house.

Not at all. Our NADCA-certified technicians use specialized tools and techniques to safely clean your ducts without harming your HVAC system.

The air duct cleaning process begins with setting up the job, bringing in the HEPA-filtered equipment and protecting the floors and furniture with drop cloths. The HVAC system will be accessed through registers and access holes, starting from the furthest point on the supply side, agitating the debris toward the main trunk line. Then the same goes on the return side, usually the dirtiest side of the system. Lastly, the air handler, blower and indoor coil are cleaned and new filters are installed before the HVAC system is powered back on.
