My Air Conditioner is Blowing But Not Cooling

My air conditioner is blowing but not cooling.

That’s a lot of hot air.

No, it’s true! It puts out air but it isn’t cold!

That means the fan is working but the refrigerant or condenser isn’t working.

That’s not cool.

The first possible cause is a refrigerant leak. Whether it is through a hose, a loose connection or a cracked condenser, loosing the refrigerant means the unit loses its cool.

Someone told me that it might have failed due to lack of maintenance, like not changing the oil. But no one told me to change out the coolant.

If the outside AC coils are caked by dirt, the heat the refrigerant conveys outside can’t escape. Then the air returns not much cooler than before.

What do I do? Buy air conditioner cleaner?

You can get air conditioner coil cleaner, or you could rinse it off with the water hose.

I heard it could be the air filters.

If the air filters in the AC are clogged, it’ll affect air flow.

I know that would overheat my car, if the air filter were blocked.

If the electrical system has problems, it may not cool well. For example, a broken thermostat would tell the AC things are at temp though you’re sweating away inside.

Or the temperature sensor in the house is broke.

Well, you know the sensor would have to be broke because you don’t have a block of ice on sensor.

Is that like the people who threatened to set up a hair dryer on the temperature sensor for Coke machines that would raise the price when the temperature goes up?

Same concept, but without the malice.

I heard it might be the drainage, but what drainage are they talking about?

If the condensate isn’t draining well, the AC won’t be able to cool well because there is too much condensation.

Is that like a swamp cooler not working well because it’s humid?

It is exactly that. And if the condensate can’t escape, it acts like insulation to the AC.
