Dust is everywhere—even in your house’s ductwork. But is it really necessary to clean out your air ducts? Let’s look at the pros and cons.
Cleaning air ducts tends to make loads of sense, at least in theory. Since dust progressively accumulates on virtually just about every surface, doesn’t it stand to purpose that it would develop up to an intolerable degree in the mainly untended HVAC ductwork that runs all through your home? Yes, air ducts get dusty. But even though air duct cleaning does not hurt, it does not often support either. You will find definitely occasions when it’s acceptable, but you will discover many times when it’s simply not vital.
1. In most properties, dust collects inside a safe variety. Your furnace or air conditioning filters trap a higher percentage of particles in the air, stopping them from entering the ductwork. Surely, that’s a cause to clean or replace your HVAC filters frequently, but it’s not a sturdy argument for taking any additional action.
two. Cleaning air ducts is not a do-it-yourself job. Even if you have been inclined to perform it, odds are very good that you simply wouldn’t personal the right tools, including unique rotary brushes along with a high-powered vacuum. You will need to hire specialists, and the price is not low. You may end up paying $500 for perform that didn’t need to be performed within the initially place.
three. Within the course of cleaning nonmetal ducts, there’s a threat of dislodging essential connections or tearing walls. If undetected, such damage could seriously effect the efficiency of the heating and cooling appliances and let particle-laden air in the basement, crawl space, or attic enter the method.
Cleaning Air Ducts – Inspection
The Environmental Protection Agency (EPA) states that no evidence exists to suggest that any health hazards stem from light dust accumulation in ducts. In reality, shuffling across a carpet exposes an individual to extra contaminants. That said, the EPA does advocate cleaning air ducts if there’s mold development visible or if proof points to an infestation by insects or rodents. Also, air duct cleaning may help to alleviate lingering odors triggered by cigarettes or other sources.
Ahead of you contact a duct-cleaning skilled for any consultation and estimate, it’s intelligent to accomplish a little investigating on your own. (That way, you do not have to take the contractor’s word for it.) Start out by getting a appear in the duct registers or grilles: Are they discolored and coated with a fine, dark dust? When you eliminate the cover, reach into the duct, and wipe its sides using a damp rag, does it come out filthy?
Go ahead and call the nearby service, if you find out that a seemingly excessive level of dust is present. Alternatively, attempt limiting dust accumulation inside your ductwork by using one particular or all the following methods:
• Set up filters more than every single of one’s hot air provide registers, following the manufacturer’s guidelines so as not to restrict airflow. Verify these filters following a couple of weeks to find out what they’ve picked up.
• With a general-purpose caulk, seal any gaps among the edge in the duct as well as the wall opening. Dust that seems to be coming by way of ductwork may possibly in actual fact be getting into by way of that slim sliver of a gap.
• Bring in an HVAC technician to perform an annual furnace cleaning. Within the course of function, he will clean the furnace heat exchanger. If he finds that it’s not incredibly dirty, in all likelihood the ducts aren’t either.
