RUUD central air blowing warm air
I have central air unit for the second floor. Few weeks ago fan on the outside unit stopped spinning and on the second floor it was blowing hot air.
I called tech and he came and changed capacitor chat after hour the same thing happened. Tech came over and said it was fan. he changed fan and when he measured pressure on hi side it was too high and low side was too low. He put bigger motor and it looked like pressure became within range 150/200.an
When unit stops I can hear whistle sound from compressor. Low side is not too cold while high side very hot.
He told me that it is probably blockage inside coil and the whole coil needs to be changed ~2k for 2T.
Can someone point me to the right direction? Thanks in advance for any help.
Probably dirty indoor and outdoor coils. Clean them.
