Home is not cooling again. Found the refrigerant levels a little low. When adding refrigerant the liquid side rises. Suction side does not rise as it should after adding and waiting some time. I believe with all the testing and results received, we have a bad txv which is not metering correctly. Freezing coils. Placing a return for service to replace txv. We might also have to do a leak search depending on levels once we return and check again.
