Customer called us out today because his system was not keeping up with the set temperatures inside of the office. Upon investigation, Troy found that there are two systems in the office. There is a Bryant system which needs a pulling clean done on the coil to help optimize its performance And the other system is a train system 3 ton straight cool that needs to be replaced at this point. Upon investigation of the train unit, we found significant amounts of ice indicating a lack of airflow. Also discovered this filters they were using are very thin and weren’t doing a lot so there’s likely a lot of buildup on the coil for the train unit. That unit is a 2004 straight cool so doing a pulling clean is not advised at that age on the system and recommended a replacement for him to consider sent him a quote for the pulling clean on the Bryant and two estimates on options for replacing the train unit.
