In our days indoor air pollution is a growing concern and most homeowners have no idea that their duct-work can accumulate mounds of dirt, dust and debris.
We prefer to have a clean air inside of our home but if is not properly installed, maintained, and operated, air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, motors and fans may become contaminated with particles of dust, pollen or other debris.
The air duct is a perfect breeding ground for microbes, insects, rodents and plenty of other unpleasant things.
You have to know that galvanized ducting buried under concrete slabs can collect water, debris or worse.
You can feel a change in the air quality and the potential for microbiological growth (e.g., mold) is increased and spores from such growth may be released into the home’s living space.
There are some clues that your ducts are performing poorly like: high utility bills in the summer and winter, difficulty heating and cooling rooms, tangled or kinked flex duct in your system.
Generally duct-work is located in an attic, crawlspace, or garage but tens of thousands of people have thin galvanized thin metal ducting buried under the concrete slabs of their homes and the piping can corrode in very short order (now it is possible to seal and clean this air ducts exists).
Duct systems are used to distribute conditioned air throughout houses with forced-air heating and cooling systems. A typical house will lose nearly 20 – 40 percent of the air moving through its duct system due to leaks, punctures, and poor duct connections. Of course, an air duct system that is well designed, sealed, filtered and maintained can make your home more comfortable, energy efficient and healthier. What is the process?
The specialist will cover the registers, and with the help of gas vacuum system will uncover one register at a time and inserts specially designed high pressure air tools into the air duct run, to loosen the dirt and debris that is electro-statically charged and clinging to the walls of the air duct system. These tools loosen the dirt and lift the debris into the vacuum stream pushing the containment to that high powered vacuum and remove it from your home. The main trunk line and the full length of each air duct are cleaned in this way.
For the galvanized ducting buried under the concrete slabs the least disruptive, and often the most affordable, method to solve your problem is to have the interior of the existing buried ducts cleaned and sealed with non-toxic latex plastic. The first step these innovative companies take is to film a video of your buried ducts. That way they can show you the exact issues. The process requires that your furnace or air handler be temporarily removed so the workers have complete access to the main trunk lines and all the branch runs of the ducting system. After the ducts are cleaned, the ducts will be inspected with a live camera that navigates through the labyrinth of ducts beneath your slab. This allows the workers to see that the duct is being coated properly with the proprietary latex compound. This sprayer makes its way through each duct and seals as it moves. It will be applied in two coats. This spray compound is similar with latex paint.
The benefits of cleaned and sealed air duct system are:
a) Enhances overall indoor air quality
- – Dust
- – Dirt & Debris
- – Mildew
- – Pet Hair & Dander
- – Mold
- – Bacteria/Fungi
- – Pollen
- – Dust Mites
c) Reduces allergy and asthma symptoms
d) Improves air circulation
e) Increases efficiency of your heating and cooling system
f) Provides cleaner living/working environment
g) Save your money
