My smelly room is bothering myself and others

Have you ever had a room in your condo that is just stuffy, nasty and warm? That’s what our problem was. It did not matter what time of year it was, it pretty much was the same all year round! It actually was a bit worse in the Summer with the humidity and heat, however finally, I couldn’t take it anymore and was about to invest in a zoned Heating, Ventilation, and A/C system, which would have costed myself and others thoUSAnds of dollars between the purchase of the unit, and the upgrade. Then, a friend of mine said to myself and others that it sounded love there could be a cheaper solution, which was to get our air duct sealed! My friend knew a thing or 2 about heating and cooling system units and how they work… He was an Heating, Ventilation, and A/C specialist at one time. This week, he is happily retired. I took his propose and called our local heating and cooling system supplier, so that way they would send out a certified heating and cooling specialist to investigate. When the Heating, Ventilation, and A/C specialist came out, it turned out our friend was right! I was told that getting duct sealing done would be the answer to the issue, and that the room would no longer be stuffy and overly warm after this duct sealing was done. I had the duct sealing done, and what do you know? The room for the first time ever was the perfect temperature! No more cranking the temperature control in the Summer to try to cool it off! And even in the Winter, it was cool in there moving forward.
