Getting the ducts cleaned isn’t exactly at the top of most people’s priority list, even if they have had a recent reminder of the benefits. To know if you need them cleaned there are several considerations to take into account.
First, how well do you breathe in your home? If you can take a full, deep breath without getting a light “tickly” feeling in your throat it’s a good sign. Or more accurately, if you notice just how fresh air smells/feels when you walk outside then it’s time to address your indoor air concerns. Duct cleaning will make the indoor air easier to breathe, especially to those with sensitivities. While some point to the fact that there are no conclusive studies demonstrating the effectiveness of duct cleaning this has more to do with the nature of the businesses performing it, as opposed to proof that it doesn’t work. As small, local businesses there aren’t many duct cleaners inclined to sponsor a study.
Next, do you have pets? Animals shed skin at a rate roughly double that of humans, and they shed a lot of hair too. There are a lot of potential allergens coming of Fido, and it’s getting into your air supply. Animal dander is in fact one of the main allergens there is, so it’s important to keep it out of general circulation if possible. Besides, have you ever taken a sniff of your dog or cat after a week or so without a bath? No matter how much you love them (and their smell) are you sure you want your house to smell like that? Maybe you do. But any company you have doesn’t.
How about the occupancy level? People are kind of the same as pets – the more there are in the house the greater the effect will be. Skin cells are the number one constituent of household dust, and the more people there are in the house, the more skin in the ducts there will be. But also, people have the habit of dropping things down the ducts as well, be it garbage, grit from their shoes, or the odd wrapper or piece of food. It’s just straight math – the people (and pets) the more stuff in the ducts.
How dry is your basement? Many a new homeowner has called us because they tore up the carpet or drywall to find black mould setting up shop in their home. And while new walls and floors can be comfortably handled by even moderately skilled handymen special equipment and skill are need to cleanse the ducts. We recommend duct cleaning as a precautionary method regardless, as the dangers of inhaling the mould spores are well known and quite substantial.
There are other factors to consider as well – such as if there were recent renovations, if you just had your furnace replaced, if you smoke indoors, if your cold air return vents are on the floor versus the walls, and others.
What it comes down is living in a clean house. Most people want their living space to be clean, and for that to be the case the ducts need to be cleaned as well. Of course, how often will depend on many factors, but for a house to truly be clean it has to have clean ducts.
So the final reply to the question “Do I need to have my ducts cleaned?” is yes. How often you get it done is up to you.
