Question about Heating & Cooling
Just so you know, The Return duct ( the large vent toward the middle of the home, and sometimes there is more than one
), is where all the dust travels to.
The filter at this point needs to be changed monthly based on it ability to grab particles from that air coming into it. A very tight weave filter will trap more dust but it will also choke off the air to the system too. Usually once a month replace the filter, some go a little longer. Dont get the electrostatic type, waste of money.
One main thing that hampers a HVAC system is not enough air flow. If all of your interior doors are closed air does not return to the inlet very well starveing the sytem for air. If the filter is clogged not enough air flow. This duct area is where it could be cleaned if it really needs it. They make long poles or a flexible shaft with a stiff bristle on the end that will sweep the dust but then you would need to vacume that dust. Tough to do yourself, expensive to have others do it and Again it really doesnt need to be cleaned. Good Luck

The complete duct system is actually a bunch of hoses behind those circular vents. Cleaning the vents is the easy part. Just unscrew them and wash them in the sink. The hoses back to the air source is a more difficult matter. It is also rather messy! It can be done with steam or compressed air but unless you are prepared for a difficult and messy job, I do not recommend you do it yourself. However, you could use a ladder and long handled bristle brush to, at least get some of the hose. Keep a vacuum cleaner handy, preferably a commercial type vac.
