Why does my AC not work on auto?

Air Conditioning Not Working in Your Car? The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.

Should the AC fan be on auto?

Keeping your fan on AUTO is the most energy-efficient option. The fan only runs when the system is on and not continuously. There is better dehumidification in your home during the summer months. When your fan is set to AUTO, moisture from cold cooling coils can drip and be drained outside.

Why is my air handler fan not coming on?

First make sure there is power to the indoor unit and that a switch or breaker isn’t off. Try setting the thermostat fan switch to the “on” position. Feel for air coming out of the vents. If it is in the air conditioning mode, check for ice around the evaporator coil and on the refrigerant lines at the indoor unit.

Should fan be on auto or on in winter?

The most obvious benefit to keeping the furnace fan on the “on” setting is more even heating and cooling distribution. Heat has a tendency to rise in the home during the winter due to “stack effect,” and parts of the home that see greater sun exposure may also become warmer than the rest of the house.

Can AC work without fan?

If the fan is not running it will not be able to remove the heat. This is a big no no, and you could fail the compressor and other components. If you are in a huge pinch, you can use a large box fan blowing on top of the unit and down into it, or pulling the hot air out, this will buy you very little time.

What should I set my thermostat fan setting to on or auto?
