Why Doesn’t My AC Blow Cold Air?

Posted on: September 1, 2014

By now you probably know every trick to keeping your home cool during our hot Largo summers. But what do you do when your air conditioner stops blowing cold air? It doesn’t matter how many ceiling fans you have, when warm air is blowing through the vents, no one is comfortable. Know what AC service company you are going to call before your system goes down so you can have the problem fixed as quickly as possible.

No matter the size or kind, your Largo AC service company will tell you that all air conditioners will follow the same basic principles to cooling your home. Once it pulls in hot air from outside, it extracts the heat from it, and then releases the newly produced cool air through the vents to be circulated throughout your home. The two main mechanisms that achieve this wonderful feat are the evaporator and the condenser. Condensers should be cleaned each year, before the high heat of summertime starts; if not, it can affect the temperature of the air coming through your vents. This is just one of the components that can cause your air conditioning to stop blowing cool air; others include:

  • Compressor. Sitting at the center of your AC unit, this is responsible for creating the cold air that comes out of the vents by compressing the refrigerant and sending it to the condenser.
  • Refrigerant. Commonly known as Freon, this substance quickly cools air as it passes through the compressor. If all of your Largo air conditioner’s parts are working fine, but it is still blowing warm air, call an AC service company to recharge your refrigerant and check for a leak.
  • Filter. If your air filters are dirty, they won’t be letting as much air through, which can feel like your AC isn’t blowing cold air. A dirty filter can also strain the unit, and cause them to wear out quicker.
  • Fan. It is an easy mistake to make to switch the fan on but not the air conditioning. This can sound like the system is on, but will only circulate the warm air inside the house, rather than cooling it.

When your air conditioner isn’t blowing cold air, you need an AC service company that will respond quickly and get the issue remedied efficiently.
