As the temperature rises outside, it is becoming more challenging for homeowners to keep energy costs low while keeping cool inside. According to the HVAC Inspection, Maintenance and Restoration Association (also known as NADCA), there is a way to decrease energy usage and still beat the heat.
“Air conveyance systems are the largest sources of energy within a home, so it’s important to clean the units whenever needed, in order to avoid increased costs and energy usage,” says NADCA President Bill Benito. “When the units are not in use, they collect a lot of dirt and dust; when they are turned on during the summer months, all of that dust and dirt gets blown back into the home.”
NADCA recommends hiring a certified contractor to inspect air-handling units and test for efficiency. Proper duct cleaning and sealing of the air handling unit will help maximize system efficiency and performance during the hottest months of the year, when the air conditioners run the most often.
“Dirty or contaminated filters and poorly maintained air handling systems can reduce air flow and efficiency. Dirty coils can cause a unit to work harder to pump out cool air, which will ultimately lead to increased energy costs,” adds Benito.
A complete and proper cleaning, according to industry standards, will remove built up particulate and contaminants, resulting in improved indoor air quality. The standard defines complete cleaning to include the inside of air ducts from where air enters the return duct, through the air handler (blower, coil and heat exchange), to the exit, where the air is released to condition the home.
