Home Air Duct Cleaning

When you clean your HVAC system it will run more efficiently. A clean blower will naturally produce more air pressure which greatly reduces the time to heat and cool your home, thus reducing energy costs. An A/C coil with dirt-free fins will not impede air flow, thus there will be no pressure drop as the air passes through it. Finally, the mechanical systems run cooler and will have a lower failure rate.

Asthma and airborne allergies affect millions of people in many different ways from a simple stuffy nose and runny eyes to portable oxygen and sometimes even hospitalization. When you enter your home, you don’t think of it as being dirty, however, there are many “hidden” triggers. Pet dander and hair, pollen, dust, mold, and even rodent feces can all hide within your ductwork. Having your home professionally cleaned can remove these allergens and help alleviate the effects, the symptoms and ultimately improve your health.

If you have a fire within your home, or even in the surrounding area, the smoke and soot will wind up in your ductwork. It will be drawn into the system through the return vents and will be circulated throughout your duct system by the blower of your HVAC system. Even though the smoke clears, the residue is inside your ductwork and permeated the insulation as well as any dirt and dust that is inside the ductwork. This smell will remain in the system and circulate until the system is thoroughly cleaned and sanitized. Soot is also a known lung irritant and for people with allergies this can exacerbate their breathing issues.

The majority of households in the United States have pets. The majority of these pets have fur. Even so-called “no shed” animals naturally lose animal hair. This loose hair is drawn into your system along with any dust and dander along with the air from inside your home. Besides being an irritant to people with respiratory problems, pet hair is a major contributor to the clogging of A/C evaporator coils. The hair gets trapped in the fins of the coil and creates an impermeable “mat” that air has a hard time penetrating. This greatly reduces the output of air and reduces the efficiency of the system.

If you purchase a new home or have renovations done on your existing home, you should have the vents cleaned out. Many people buy a new home thinking it is sparkling clean. However, during the period of time the home is built there is a lot of wood, sheetrock, concrete and ceramic dust that is created. Renovations such as a bathroom remodel or home additions also cause construction dust, especially sheetrock dust. Drywall dust contains Crystalline Silica. Silica particles are listed as hazardous materials by OSHA and can cause lung irritation and other breathing problems. No matter how careful the contractor tries to be, a good portion of this dust winds up in your ductwork. Here it will remain, and will continually circulate through your system, unless it is thoroughly vacuumed out.

Many homeowners assume that if they change their furnace filter on a regular basis, they don’t need to have their vents professionally cleaned. The average filter will only catch 30-70% of the particles that pass over it. Even the most diligent homeowner uses the best filter, a lot of dust and debris is going to circulate in the system.

A malfunction in the furnace or boiler often calls for a thorough duct cleaning to fully remediate. Oil burners, furnaces and water heaters can have a “puff back” incidence in which a small explosion of unburned oil occurs in the combustion chamber. A clogged furnace chimney or a crack in a heat exchanger can also send soot through the home. All of these incidences can send soot throughout your home and result in a health hazard if not removed.

As discussed, there are numerous reasons to have your air ducts professionally cleaned. Do a little bit of research before you open the phone book or search the internet for a service provider. Make sure the company you hire is certified by NADCA, the National Air Duct Cleaners Association. You should also check with your state’s Better Business Bureau and ask if they have any complaints about the company you choose. Finally, if you are a member of Angie’s List, check their site and read reviews given by past customers. The contractors with consistently high ratings will receive their Super Service Award; check to see if the duct cleaner you choose has received this honor.
