When was the last time you had your air ducts cleaned? Every year, the average home collects up to 50 lbs of dirt, dust and allergens in its air ducts.And, every time you use your heat or air conditioning these pollutants are circulated throughout your home, aggravating respiratory conditions like asthma. This is why it’s important to invest in a professional air duct cleaning service. At Global Cleaning & Restoration, we use a powerful HEPA-filtered vacuum to clean air ducts and vents. This vacuum flushes all traces of dirt and dust out of your air ducts, removing them from your home.
