Evaporative Coil Cleaning Chino Hills, CA


     Homeowner at this residence started to notice poor airflow during one of the hottest months of the year. After searching the web, she contacted AQS Heating and Air Conditioning to help her find a solution. She expressed her concerned with the weak airflow in most of the rooms and had also noticed that the condenser fan motor was not working as intented. 

   Upon inspection our experienced technician found a dirty evaporative coil and frozen coils. Frozen coils caused blockage our air resulting in significantly weaker air flow. The equipmment was running harder than it should and causing undue strain to the system components. The solution included removing the evaporative coil to complete deep cleaning and condenser maintenance. These services were performed and system started working properly. 

      The homeowner was happy and stayed cool during the summer.  AQS Heating and Cooling is pleased to have helped her increase her system longevity, improve air flow and air quality.
