The previous owners had six pets in the household and they shed a lot of hair and pet dander.
My wife and I were looking at houses for 6 months before my pal and I found the place that was right for us, each one of us had a list of things that my pal and I wanted in the household and that included a fireplace, large bedroom, eat in living room, and more than one lavatory, then my wife and I looked at a lot of different houses. Some places were too small and others required too much upkeep. When my pal and I found the place that was right for us, my pal and I had a business come to the place to investigate each part of the household for concerns, and during the investigation, my wife and I found out that the air duct needed to be cleaned and sanitized. The previous owners had six pets in the household and they shed a lot of hair and pet dander. The duct toil in the household was riddled with hair, dander, dust, and debris. My wife has terrible seasonal dust irritations and I knew that the air duct was going to be a problem with all of those indoor pollutants inside, however before my pal and I moved to the property, my pal and I hired an Heating, Ventilation, and A/C business that specializes in air duct cleaning, sanitizing, and ceiling. The Heating, Ventilation, and A/C business cleaned and sanitized the air duct and when they were done they used a special glue polymer to seal up all of the little holes. We have a one year warranty on the service, however having the duct toil cleaned and sanitized was a great idea, because it very changed the indoor air quality and made the household smell very fresh and clean.
