I had a drastic issue with finding small puddles of water in the hallways of my house recently. It seemed that it came from the air vents of my central heating and a/c component leaking! I did not believe what was causing this as my heat and a/c had been laboring good and there had been no signs of a chop down coming or lack of air flow. I just could not figure out what was going on or how to stop it. So i had no option however to call the local heating and a/c supplier to send out a certified heating and a/c specialist to take a look at things. I did this, and when the local heating and a/c specialist from the local Heating & Air Conditioning supplier took a look, he found that the answer to the issue was to have my HVAC duct sealed. What was happening was the rain from outside was somehow getting into the HVAC duct and flowing through my air vents a little bit. It was going to cost a few bucks to have my HVAC duct sealed. But it was something that needed to be done if I did not want my hallways flooded and potential mold forming, so I did. And right after the HVAC duct sealing task was done there was no more puddles of water and my air vents were acting normal again. Eventually I could have had some real troubles. So was a nice thing I decided to call the local heating and a/c supplier to have it all checked out!
