Has Your Airflow Reduced Over Time?
Does it feel like the airflow from your air conditioning vents isn’t what it used to be? If the airflow has diminished, you are probably wasting energy and wearing out your system unnecessarily. When cooled or warmed air from your HVAC system isn’t making its way throughout your home or office efficiently, your system, the most expensive appliance in your home, is working harder than it should. Reduced airflow can cause your house to be too hot or too cold. There are several common causes of low airflow from air conditioning vents. The Duct Cleaning Pros help determine the best way to improve your HVAC system airflow.
Problem 1: The Air Filter
Problem 2: Dirty HVAC System
While proper filtration helps keep heating and air conditioning components clean, even the best filters can’t fully protect your HVAC equipment from getting clogged with mold, mildew, dust, dirt and debris. Scientific research has shown an average 37% decrease in HVAC system efficiency is common with less than 0.02 inches of buildup on the system’s coils.
Most homeowners don’t know that their air conditioning system has two sets of coils. The Condenser or “Outside Coils” are obvious. It’s hard to miss that metal box with the aluminum fins and big fan. But those coils work together with the evaporator or “Inside Coils” to cool your home in the summer. Unlike the condenser coils, the evaporator coils are typically located in the attic, a closet or even in the garage. You can easily wash buildup off the condenser coils with a garden hose, but that won’t work so well in your attic. That’s why the US EPA recommends regular, professional cleaning of the evaporator coils and other components of your HVAC System.
Dirty air handler components can negatively affect both heating and cooling efficiency and can contribute to airflow issues. In addition to regular cleaning Learn more about Air Filters HERE. (LINK to Air Filters Page)
Problem 3: Duct Leakage
A Few Words about Duct Tape
Are you a D.I.Y. repair person? Think twice before you use duct tape to repair your leaky duct? The name “Duct tape” is a misnomer. Though the product is incredibly strong and sticky. The adhesives degrade rapidly in extreme temperature changes. In 1998 the Department of Energy’s Lawrence Berkeley National Laboratory conducted tests of many kinds of duct tape under conditions simulating real heating and air-conditioning environments. Here’s what they said, “We tried as many different kinds of duct sealants as we could get our hands on. Of all the things we tested, only duct tape failed. It failed reliably and often quite catastrophically…”
