I have a york gaspack (older) Model # D1GA036N08006A.
I appears the blower motor is set on the low output setting, as it only is slightly detectable at the regesters inside the house. (I have cleaned both coils and changed all return filters and still very little output on supply registers. Can the fan motor be set to medium or high output manually, by changing leads on the motor? Does the AC unit automatically monitor and make these changes? How can I increase the output to my supply side registers? Thanks for your help!!!
Call a pro to check it out!
The evap coil may not be as clean as you think.
What size is tyhe return and supply.
The motor should be a multi speed, but that may not be the problem, how long have yoou had this unit, did you recently but the house.
