When you notice that your family has health concerns especially whenever you are in the apartment then the culprit is almost constantly a dirty Heating & Air Conditioning duct. Dirty vents carry dirty air all through the apartment & this is the same air you & your family breathe which can be detrimental to your health with time. I noticed that my children would get sick each time they were in the house. A call to the Heating & Air Conditioning tech confirmed my theory. He suggested that as well as the zone control method already in my house, It would be wonderful if I added an media air cleaner. The Heating & Air Conditioning professional explained that the air quality systems functioned by sieving all the impurities & pollutants in the air within the house. All the pet dander, dust, & dirt would be cleansed from the air thus significantly improving the air quality within the house. This would mean that the air we would be breathing would be clean thus promoting our health. However, to maintain the indoor quality of air, the experts explained that I would have to schedule ductwork cleaning services at least every 1 to more than one years… Regular duct cleaning would promote clean air which would help with our health & also assist with the respected function of the media media air cleaner unit. These units, but, did not come with a temperature control unit as they did not need it. The homeowner solutions supplier proposed that if I had fitted the machine while we were in the initial Heating & Air Conditioning installation, then it would have entirely helped keep down the dust sensitivity flare-ups. I would get a set of filters from the Heating & Air Conditioning provider & substitute them in order to keep the vents clean.
