  • Duct Cleaning

    Most people don't see the need for duct cleaning. But then, most people don't see all the dirt, dust, pollen and other particles that have built up inside their heating and cooling ductwork. If they could, they'd be scheduling a visit from the professionals at Shannon Heating & Cooling. We can remove the contaminants from a home's duct system, so that the air circulating indoors is fresher and cleaner. The results are a cleaner home, and a comfort system that operates more efficiently. Why not schedule a duct cleaning for your home, and see the benefits for yourself?

  • What's in Your Duct Work?

    Do you or your family members suffer from allergies? Dirt, dust, bacteria, and other pollutants living inside your duct work may be to blame. These pollutants are known to trigger allergies, asthma, immune system deficiencies, and other chronic illnesses. Young children and the elderly are especially vulnerable to these contaminants.

    Having your duct work professionally cleaned could improve your family's health, eliminate odors, and cut back on housework like dusting.
