Do you need duct cleaning at all? If your house has ducts, the answer is yes. The ductwork of the average six-person home circulates 40 lbs. of dust through it per year—and plenty of that gets trapped along the duct walls, creating an even greater build-up over time. It only takes a year for a thin layer of dust to develop, and that’s enough to start causing a drop in HVAC system efficiency.
(This, by the way, is one of the reasons more homes today are built for ductless HVAC systems. No ducts, no need to clean them.)
We recommend our customers schedule duct cleaning in Glendale, AZ every three to five years. If you have never had your ducts cleaned, you’re probably overdue for this service. However, if you’d like some more solid indicators telling you it’s duct-cleaning time, we’ve put together a list of ways to tell.
The Brute Force Method: Photograph the Inside of the Ducts
We’ll start with the direct way to look for signs to schedule duct cleaning—get a look at the interior of the ducts. You can’t see inside most of the ductwork, obviously, but there is a way to get a good sense of what it looks like, which is to use a digital camera, such as the one on your phone.
Remove the register from one of the supply vents in your house, then reach down inside with your camera and snap a few images. If the images show something that looks like a clogged filter from a car, time for duct cleaning.
The Dusty House Method: Just How Much Are You Dusting?
Thickly congested ductwork will send out dust into your home each time the blower fan comes on. This means dust is circulated through the living spaces without escape, and you’ll see the results on surfaces around the house. If it seems like you dust and dust and nothing improves, the ducts may be to blame.
The Musty Air Method: Your Vents Smell Bad
When you turn on the AC or heater, do you notice a dusty or musty odor coming from the vents right as the blower fan starts up? This is the excess dust inside the ventilation system being blasted out, and it means there’s a lot more dust where that came from.
The High Cost of Comfort Method: HVAC Bills of TERRIFYING PROPORTIONS (IN 3-D!)
We’re not exaggerating too much here. Clogged ductwork is one of the biggest sources of drops in HVAC efficiency. The resistance placed against airflow from the blower affects both heating and cooling. When you see your bills for either the AC or heater climbing and you can’t tell why, we recommend you take a closer look at the ducts with the camera to see if duct cleaning will solve the problem.
We hope you now have a good idea whether you need to have professional duct cleaning done. We’re the people to call to handle the job effectively and quickly.
