Help with AC. After running our AC for 5 months, we were finally able to turn it off at night last week an open the windows. Then it go hot again and we turned it back on. Now it comes on and blows blows cold air and stops, but we can still hear air coming through the vents. It’s not cold or hot, just room temp. Why does the air keep running after it’s reached the temp on the thermostat? It is a split unit and both are on. We even tried turning both thermostats to off, but the air still runs.
