How Cold is the Air from My Air Conditioning?

Having air conditioning in your home is a wonderful luxury during the hot summer months. Rather than having to move fans around your house and open up windows in search of a cooling breeze, as we used to have to do,  you can simply set your AC system at the right temperature and forget about it. But what temperature is the air that is produced by that system? And can you change it? This article will look at those interesting questions.

An Air Conditioning Primer

Despite being in millions of homes and businesses, there is a general misunderstanding about how air conditioning works and what the system is doing when it is running. No, an air conditioner does not “make” cold air. While it might sound like a minor difference, what an AC unit actually does is pull heat out of the air, causing it to feel cooler when it is returned to the living spaces in your home.


So, within an air conditioning system, there are two streams of air – the air going into the unit, and the air coming out. Those are called “return” air – the air going into the HVAC equipment – and “supply” air, or the cooled air being supplied to the building. When trying to figure out how cold the air will be when it comes out of your air conditioning system, you first need to know what temperature the air was at when it started.


A Consistent Change

If you set your air conditioner to 68*, you shouldn’t automatically expect the air coming out of the vents to be precisely 68*. In reality, it might be warmer, or it may be cooler. It all depends on what temperature the air was when the system started running. When an AC system is working correctly, the supply air will be roughly 15* – 20* cooler than the return air. That’s the range that the system is capable of achieving when things are running properly and there are no leaks or other issues.


Based on the setting of your thermostat, the system will continue to run until the interior temperature of the space comes down to your desired level. This could take just a few minutes, or it could take quite a long time if you started with a particularly high temperature inside (or if the system is not running efficiently).


Spotting the AC Problems

If the air conditioning in your home doesn’t seem to be working properly, you can bring in the team at Berico to figure out what is wrong. One of the ways the system can be tested is to evaluate the temperature of the return and supply air to make sure there is a suitable difference between the two. If not, something in the system is not working correctly, and a repair will need to be completed. Call for assistance today to get your air conditioner back into working order.
