PRO TIP: What can you do to help air filtration?

Check your air filter each and every month. Dirty air filters are the leading cause of A/C malfunctions and are easily prevented. Clear away grass, weeds, leaves and other debris from the outdoor condensing unit. Clean indoor vents, making sure furniture or draperies do not block them so the air can circulate freely and keep ductwork clean.


If your ducts have not been cleaned by a professional service, they are probably wasting energy. In an average six-room residence, up to 40 lbs. of dust is generated annually through normal living. Your heating and cooling system takes air in and pushes it out. Over time, contaminants gather in the ductwork and contribute to health problems. Dirt and contaminants within the system cause it to work harder and reduce the operational lifespan. According to the US Department of Energy, air conditioners use about 5 percent of all the electricity produced in the U.S., costing homeowners more than $11 billion a year in energy costs. When an HVAC system is free of dirt and pollutants, less energy is used, leading to improved cost-effectiveness.
