We’ve been in this home for over 10 years, and we’ve never had our ductwork cleaned. Maybe that’s the reason why I can’t stop sneezing. The HVAC system was already installed when we bought the house, and it is now at least 12 years old. My wife complains all the time that the A/C is on too much, and that she’s always cold, so I have to admit, the air conditioner probably works just fine, if I could just get my wife to leave the thermostat alone. However, the sneezing is something that I am very tired of. I don’t sneeze a lot at work, so I do believe that I have an air quality issue. I spoke to a local HVAC service agent that came by my office the other day to check the heating and cooling equipment there, and he gave me his card. He mentioned that the air duct cleaning is the process of removing dust and other contaminants from the ductwork. Those nasty contaminants gather over a period of time, inside the ductwork and they can end up inside the home, floating around. Maybe that is why I sneeze a lot when I’m home. The air ducts, as he explained to me, is like the circulatory system of the home, and are the pathways for heated or cooled air to be able to travel throughout the house, which is exactly why air duct cleaning is so important, and since the ductwork has never been cleaned while I’ve lived here, I think it is time, so that I can stop sneezing so much.
