Reasons Your AC Is Not Blowing Cool Air
When you turn the air conditioning on, you expect it to cool your house. When your air conditioning is having issues cooling your home, there are a number of things that may be going on. Sometimes, the issue can be something simple that you can easily remedy yourself. However, other times the issue will be something that you need to have a repair technician to take care of for you. Here is information on some of the things that may be causing your air conditioner to stop putting out cool air:
The thermostat is set wrong
The first thing you want to check when you notice the air coming out of the vents isn't as cool as it should be is whether the thermostat is set correctly. If it is set to 'on', then you want to switch it over to 'auto' instead. When it's set to 'on', that means the fan is going and the fan won't cool the air.
The filter is dirty
When the air filter for the air conditioner is dirty, it won't allow the system to pull through as much air as it needs to. When there isn't as much air flowing through the system to cool, there won't be as much cool air coming out. This can cause noticeable drops in the cool air you feel coming from the vents. Change the air filter and don't use the AC again until you do get a new one put in place if this is found to be the issue.
The unit is frozen
Your air conditioner can freeze, and when it freezes, it won't continue to cool the house. It can freeze for different reasons. A dirty air filter can cause the unit to freeze. Another thing that can cause it to freeze is not having enough refrigerant in it. This could happen because of a refrigerant leak. The fan not working properly would be another possible cause for freezing that a technician will need to fix. A drainage problem can also be the culprit. If you feel the unit is frozen, turn it off. If the air filter is dirty, change it and wait a few hours before turning the unit on again. If the air filter isn't the problem, then keep the unit off until an air conditioning repair person comes to have a look at the AC.
