Spring Air Conditioning Repair for a Residential service call near Klamath. Found the system that covers 1st&2nd floor was not cooling. Checked inside unit and found filter dirty. Replaced customer supplied filter. Checked outdoor unit and found my pressures running at 9psi over 250psi indicating a restriction somewhere. Checked filter dryer and it was good. Opened up coil and found txv starting to ice up. Txv is stuck closed looks like it got to hot upon install. Sent estimate for repairs. Customer happy on departure.
