They just push the vacuum through the odd vents and suck up whatever is in the ducts.
The Spring season is actually my preferred in Springfield, Missouri… I adore the blooming flowers, trees, and shrubs; The weather is gorgeous so I can do some turf work and painting outdoors. The downside of Spring is the pollen though. I also live on a dirt road. The sun dries out the dirt and causes it to stir up dust. The pollen and dust irritate my flu symptoms. I have had a stuffy nose, headache and sinus pressure the whole season, then recently I noticed that I was struggling with my flu symptoms past the Spring season in my Springfield home… What is the deal with that? I then did some research and relayed that the air quality in my condo was no good. The dirt from the road, pollen from flowers, and dirt from my Heating and Air Conditioning got up into my HVAC duct. I had never called a Missouri Heating and Air Conditioning company for HVAC duct cleaning before, however so that is why everything was so dirty, however calling for HVAC duct cleaning is easy. In Springfield you have a wide range of dealers that do this. I choose one that doesn’t do a disinfect brush, but a vacuum. That way they don’t terrify the HVAC duct or my household. They just push the vacuum through the odd vents and suck up whatever is in the ducts. They then use a camera to make sure they got it all. It is gentler and more effective than the ancient brush method, and after my HVAC duct cleaning appointment, I felt so much better. The condo felt and smelled so much fresher. The Heating and Air Conditioning seemed to work better as well.
