Springtime Air Conditioning Repair for a residential customer near Wolf Creek. Upon arrival found the system not cooling as well as it should. Checked inside unit and found everything operational, checked inside evaporator coil and found two big oil spots on bottom front left and right corners. Homeowner stated that they put refrigerant in it two weeks ago and reading pressures now system is a little low. Checked what kind of warranty system has and system is still under parts and labor warranty but only has 3 months left. Parts and labor are covered if repair is done by a York dealer. Only parts are covered if work is performed by a non-authorized dealer. Gave estimate for warranty repairs since were a Lennox dealer. Recommended homeowner getting a York dealer out to replace the evaporator coil.
