That tool looks love an airsoft gun.
There are certain things a homeowner can tackle themselves plus others they cannot. I think I can do my own oil change on a car. I can’t however, do any major repairs with the brakes or engine, and with the Heating & Air Conditioning, I can change air filter, clean the fan blades plus even add more freon if needed. Anything greater than that, I am stuck calling the professional. I would really love to expand my skills. I think especially in ductwork I can do some of the work! Every couple of years a homeowner should pay for ductwork cleaning. I have watched a duct cleaning appointment. It is not all that impressive. The Heating & Air Conditioning supplier takes a large clean brush plus pushes it through the air vents. The Heating & Air Conditioning professional just seems to think where the brush should go plus twirls it around. It is not absolutely scientific or difficult looking. The only thing I would need is the actual scrubbing tool. I wonder if I can fashion my own or if there is a reason Heating & Air Conditioning suppliers all have the same brush. There must be an online store that sells Heating & Air Conditioning unit though, then getting the ductwork cleaning tool should be straight-forward, and ductwork sealing would be a little more difficult. That tool looks love an airsoft gun. The gun has sealant particles in the air that it blows out. I wonder how much that tool is plus how much it is to get it refilled. I love the proposal of being able to do duct sealing anytime I want to. I would save so much money.
