I had a bit of a sticky issue lately, and when I mean sticky, I easily absolutely mean it in every single sense of the word! To get right to the point, the air vents of my Heating, Ventilation as well as A/C component were not closing when I wanted them to, but so, since the air vents would not close, I decided to try a little do it yourself kind of thing, and bought some duct tape, you see, what would happen, is every time that I tried to close the air vents, they would stick and then slam right open again. When I got the duct tape and put it on the a single part of the air vents that seemed to be causing the issue, these things easily would stay shut. It would be a bit of a task though having to scrape off the duct tape to be able to open up the air vents once again when I wanted the air to come out in that particular room; After about 2 months of dealing with this, I finally decided to break down and just call my local Heating, Ventilation as well as A/C company to come out to try to service these air vent troubles I was having. The Heating, Ventilation as well as A/C specialist that they sent kind of laughed at myself and others with the duct tape all over the venue, then he was able to service the sticking air vents within a matter of minutes. He and the heating and a/c company he worked for were absolutely cool about the whole situation. They didn’t charge myself and others the full minutely rate, and pro rated the Heating, Ventilation as well as A/C call to charge myself and others for just a half an minute.
