A system running but not cooling almost always comes down to charge, airflow, or a failing component — we test all three.
A tech who explains superheat and subcooling readings instead of just saying 'it's low on freon'.
A system that's technically running but not actually cooling the house is one of the most misdiagnosed hvac complaints there is, which is exactly why ac repair calls in Denton, TX get treated with urgency, not a next-available-Tuesday slot.
