AC Not Cooling in Lacrosse, WA
An AC not cooling in Lacrosse, WA is the most common call we take all summer. The system runs. Air moves. The house still sits at 79 degrees at 6 pm. That pattern has a short list of causes, and our crew works through it in order instead of guessing.
First we check the temperature split. A healthy central air system drops return air about 15 to 20 degrees across the evaporator coil. If the split is 8 degrees, the problem is on the refrigerant side or the airflow side, and we go looking. A clogged filter or a matted evaporator coil chokes airflow. A dirty outdoor condenser coil can't shed heat. A slow leak leaves the system undercharged, which shows up as low suction pressure on our gauges and often as ice on the suction line. Our page on refrigerant leak repair covers how we trace those.
Sometimes the unit is simply too small for the house, or ductwork in a hot attic is leaking cold air into the insulation. We'll tell you straight if that is the case.
Call (866) 703-1217 and our crew will measure what your AC not cooling problem really is before we quote a repair.
