01/16/2026 Dirty HVAC coils can significantly affect how efficiently your heating and cooling system operates. When evaporator or condenser coils collect dust, grease, and debris, heat exchange becomes less effective. As a result, the system has to work harder and longer to keep your home at a comfortable temperature.
HVAC efficiency studies have shown that buildup on coils can increase energy consumption by over 40%, and in heavier cases, energy use may rise by up to 60%. This added workload not only increases utility costs but also places unnecessary stress on system components.
Restricted coils also reduce airflow throughout the system. Research and field testing have demonstrated that cleaning internal HVAC components can restore approximately 10% to 46% of lost airflow, allowing conditioned air to move more freely through the ductwork. Poor airflow often leads to hot and cold spots, longer run times, and reduced indoor comfort.
As dirt insulates the coils, the compressor is forced to run longer and under higher pressure. In some cases, dirty coils have been linked to up to a 30% increase in compressor energy usage, accelerating wear on one of the most expensive parts of the HVAC system.
Routine professional coil cleaning helps maintain proper airflow, improves energy efficiency, and reduces strain on HVAC equipment. Keeping coils clean allows the system to perform as intended, supporting consistent comfort, lower operating costs, and a longer overall system lifespan.
