When you notice that your family has health issues especially whenever you are in the house then the culprit is almost always a dirty HVAC duct.
Dirty vents carry dirty air all through the house and this is the same air you and 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 HVAC tech confirmed my theory. He recommended that in addition to the zone control system already in my house, It would be great if I added an air purification system. The HVAC professional explained that the air quality systems functioned by sieving all the impurities and pollutants in the air within the house. All the pet dander, dust, and 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 air duct cleaning services at least every one to two years. Regular duct cleaning would promote clean air which would help with our health and also assist with the proper function of the air purifier unit. These units, however, did not come with a temperature control device as they did not need it. The homeowner solutions company advised that if I had fitted the unit during the initial HVAC installation, then it would have really helped keep down the allergy flare-ups. I would get a set of filters from the HVAC provider and replace them in order to keep the vents clean.
