Clean Coils Improve Energy Efficiency

Clean Coils Improve Energy Efficiency (NAPSA)—Thecost of operating dirty air-conditioning equip- ment is greater than you might expect. Not only are energy costs increased, but life expectancy of the equipmentis also shortened. That’s because dust and debris reduce the ability of an HVACsys- tem to provide heating and cooling. Consider that systems with dirty coils use up to 37 percent more energy to cool the home. While cleaning the coils helps cooling systems run moreefficiently, the coils do not need to be removed—or “pulled’”—to be properly cleaned. Pictured above: a training session for HVACser- vice technicians. Maintenance and repair costs are also affected by dirty coils. Higher operating pressures and temperatures caused by dirty coils may cause the compressor’s lubricant to break down. In addition, acid formation can occur. Both lubricant breakdown andacid formation seriously compromise the compressor and ultimately lead to failure. Coils should be cleaned at regu- lar intervals for optimum effi- ciency.
