Last night I returned home from a month long vacation. Outside temperature was about 90, and the humidity was very high. I turned the a/c on and set the thermostat to 68 degrees. The a/c ran for at least four hours, and the place felt much cooler, but the temperature was still at least 74 degrees. I'm sure it felt cool because the humidity was lower, but the temperature didn't fall. The nice thing about this system is that it's quiet because the air speed is normally low, but this means the unit runs longer, especially for large changes to the thermostat setting. Does the unit need servicing, like maybe a refrigerant charge? It's a Rheem, newly installed in 2000. So far, never need any servicing. Thanks, Ray

Probably needs the condenser professionally cleaned. And check the freon level. And it most likely needed service after four or so years. 14 is way too long.

Does my air conditioner need service

the air temperature until after the humidity is reduced. So yes, it will take longer to actually lower the air temperature, but you will ***feel*** cooler as soon as the humidity is reduced.

Less dense than cold moist air? Sure, so what? The AC will still be conti nually lowering the air temperature.

My thermostat has a "vacation hold" feature, which allows you to set a different temperature for a selected number of days.
