Carrier FC4BNF036 Air Handler (3 ton) sick
Hello all, No0b With a quick question. Appreciate any help you are willing to give! So, Beginning of hot season it would take quite a while but the unit would eventually cool the house down from 80 during the day to 73 at night. 90 - 95 degree outside temp. All of a sudden one night it stopped cooling so well. I noticed that the cooler it is out the better the unit feels. Some times it feels mildly cool and other times ambient. I took apart the air handler to do a cleaning but everything was spotless. There are no strange noises, the unit had worked ok, etc. I have a 1500 sqft house, 1 zone, 3 ton unit. I noticed that the coil was rusted on the sides. Unit is 8 years old. I don't have the money for a pro right now to replace large items. Any suggestions? FYI the outside unit is 1 year old and clean. Everything kicks on when it should as well.
