HVAC systems are some of the most essential systems in our homes. And why is this? The answer is pretty simple—they ensure that your home is comfortable for living throughout the entire year. But, did you know that the more your HVAC system runs the more debris and dirt accumulate in the ductwork?

This shows that you need to regularly inspect and maintain your ductwork if you want to improve your indoor air quality, and also keep your HVAC system energy efficient. So, how do you determine that your ductwork needs maintenance? Have a qualified HVAC technician conduct an HVAC duct inspection to check for any signs of damage or debris accumulation. Always avoid DIY ductwork. 

Here’s a guide to air duct inspection

Step 1: inspect the vents and air registers

The first thing to do when inspecting your home’s ductwork is checking the air registers and vents. This is the easiest way of checking whether there are signs of dust or any other type of debris. If you notice this, it’s an indication that you need to clean your ductwork, as there might be debris stuck inside the ductwork. 

Step 2: inspect the air registers thoroughly

Once you inspect the vents, it’s time to inspect the air registers too. To inspect the air registers, take a screwdriver, open the vent grills, and check inside the ducts. If possible, get a flash camera, and take a few photos of the ducts, as this will give you a better look at your ducts. In case you notice some signs of dead insects or animal droppings, there’s a possibility that you have a pest infestation. The best thing to do at this moment is to seek the services of an exterminator.

Step 3: clean your ducts

Lastly, ensure that you contact an HVAC professional to clean and seal your ducts. If you notice that there’s a lot of debris in your ductwork, don’t do DIY cleaning—not unless you have the experience. Always let a professional do the job for you. With this, you won’t need your ductwork to be inspected or cleaned for the next five years. 

Once the cleaning is done, it’s always a good idea to ask the professional to seal your ducts— this helps in reducing the amount of conditioned air leaking out of the system.
