Came out today to give quote for duck cleaning. Upon visual inspection of system found the blower wheel to be dirty, the indoor coil has biological growth and buildup on it. There is currently biological growth in the system. Customer did not want to move forward with installing a UV light to kill and prevent any more growth in the system. Customer elected to move forward with the duct cleaning and dryer vent cleaning. At this time, customer would like to discuss options before moving forward with any other work.
