06-24-2024. Jake Kring. I arrived for a previous customer no cool call. I spoke with the homeowner and found that the show running but not keeping up on the hotter days. I inspected the system and found it to be dirty and also needs a new filter. I found the condenser fan blade to be throwing air sideways instead of up and this was causing the system to have a high head pressure. I cleaned the condenser coil and the head pressure dropped and the system starts cool much more efficiently. I explained that the system ends to be cleaned and kept clean for it to be able to reject heat correctly. I explained the purpose of the blade and its pitch and how it rejects the heat off of the condenser coil. At this time it’s after 5PM and the manufacturer is closed I will have to call for pricing and availability tomorrow.
