Is Your Home's AC System Not Blowing Cool Air?

It’s almost summer and the temperatures are crazy hot. This is when you need your air conditioning system the most to make sure you’re comfortable in these warm months. Too much heat can be hazardous for you and your family’s health.

But one of the problems that most of us face is that when you do need your AC to work, sometimes it just won’t. Instead of it blowing the cold air that you need, it blows warm air.

It is important to note that extreme heat can lead to illnesses like dehydration and heat stroke. You don’t want this to happen, given that if they are left untreated, these can lead to serious conditions or even death.  

There are a few reasons why your AC is blowing warm air. Below is a list that will help you determine the cause and solve this problem once and for all. A few of these you can attempt to fix on your own, but it would be best to consult with your local HVAC experts to make sure your system is always up and running.  


Your AC may not be the correct size.

Your AC setup needs to be sized properly. If you decided on this on your own, and it turns out the AC is not functioning as it should be, then it may be because the size is not the right fit. It does not necessarily mean that you need a bigger equipment to get a much cooler air. This is not how air conditioning systems work. If your system gets overworked, it generates less cold air. Make sure that a knowledgeable technician measures and checks your space to make sure you get the right size, and subsequently, a much better and efficient AC unit.  


Check your thermostat settings.

You need to know how to set your AC. Knowing the difference between the ON and AUTO settings will significantly impact how your system cools your space. Setting the thermostat to ON will make your fan run even when your AC is not yet cooling the air. Switching it to AUTO will allow it to only blow cool air.


It could be low on refrigerant.

When your system is low on refrigerant, there is nothing else you can do but call a professional. Your AC unit might have a leak. This is how the refrigerant escapes and this could be why it isn’t cooling as it should be. Make sure to get the leaks repaired. The refrigerant will make your system function efficiently again.


Check on your air filters.

Putting in a fresh new filter can make a huge difference on how your AC cools your space. There are so many reasons as to why your filters get clogged and dirty. You need to replace them based on need. If you have pets at home, your air filters will get worn out faster than they should. You should also take this into consideration. Dirty filters block the air.


Your condenser or evaporator could be dirty.

Check on your condenser especially if it is located outside your home. If this is clogged with dirt, twigs or any other debris, this will hinder the optimum performance of your AC unit. Make sure to have a technician check on this, too, just in case there are more pending problems.


If you have checked all of these, and your AC is still not blowing cool air, then call your local HVAC professional immediately. You need to make sure your indoor air is cool enough to keep you comfortable for the summer.
