Clean Air Claims

In order for your forced-air furnace or HVAC to deliver warm and cool air into your rooms, that air has to go through a system of ducts. So that would mean that you’re breathing in any dust, cobwebs, pet hair, and dander that line those ducts.

Although that sounds harmful to your health, that is not actually the case according to a study done by the U.S Green Building Council.  There has never been data that suggests duct cleaning has a positive impact on indoor air quality and human health. However, that is only true when your ducts are airtight.

Leaky ducts can pull in dirty air and allergens from basements, crawlspaces, garages, and attics — and blow it all around your house.

So unless your ducts are leaky (easily fixed with foil-backed duct tape and insulation), or you have a special need, like a compromised immune system, nasty allergies, or you just did major construction, you probably don’t need to worry about air quality when it comes to the state of your air ducts. However, for those that do have special needs like those mentioned above, it is best to consult with a professional HVAC professional in your area, like HVAC Philly, who are located in the greater Philadelphia, Bucks and Montgomery County, PA area.

Special Circumstances

Of course, there are always exceptions to the rule. Both the EPA and the National Air Duct Cleaners Association recommend professional duct cleaning if you have mold growth, vermin, or excessive amounts of dirt and debris in your ducts.

How, exactly, do you know if you have vermin in your ducts? You can actually look yourself. Do a visual inspection by pulling off the register grill and looking around with a flashlight, or stick your arm in and take a photo with your phone.

If you see mold, or a dead mouse, or any type of evidence that there may have recently been a live vermin, like droppings, go ahead and call in a pro. Get those ducts cleaned!

Another situation that calls for cleaning, is right after lead paint remediation. You wouldn’t want to have that being dispersed into the house when you turned on the heat.

And finally, if you just feel better knowing that your air ducts are clean, or the thought of dirty ducts is upsetting to you, be your own special circumstance. It is an individual preference.

Be Wary of Scammers

If you have finally weighed your options and decided that you would like to proceed with having your air conditioning vents cleaned, you just need to be wary of scams. Stay away from companies willing to clean your ducts for $49 or another too good to be true figure. In most cases they’ll do a quick inspection and some vacuuming, tell you there’s mold growth and charge you thousands for clearing it out. It is common enough that the National Air Duct Cleaners Association has an anti-fraud task force.

Look out for duct cleaners claiming they will sanitize your system. By definition sanitizing or disinfecting requires extremely high kill rates and there is no way that a professional can guarantee 100 percent saturation.

Cleaning your ductwork alone is not going to make a difference. A real professional will know that, and should do annual maintenance on your entire system, including the air handler Otherwise it’s the same as dusting your ceiling fan after you’ve vacuumed.

So how much will it cost, and how long is it going to take? Typically, duct cleaning takes two to five hours, but it can go on for two days if you have a large house with lots of ducts. On average you should spend $300 to $700.
