AC FAQ: System Blowing Warm Air?

man-with-fanWhen we’re in the midst of the summer season, there are certain things you want to do. Get outside, soak up the sun, go swimming, maybe check out a ball game or two. What you probably look forward to the most as your day draws to a close, however, is simply getting home and getting out of the heat! That’s what makes it so disheartening to enter your living space only to discover that your AC is blowing around warm air!

The good news is that this is not necessarily the result of a serious problem with your air conditioner. The bad news is that, well, it just might mean that you have a serious problem with your air conditioner. The key to handling the situation is to have a skilled professional make the diagnosis—usually. There is one specific solution in this post you can definitely handle yourself. So read on, and schedule your AC services in Clive with us.

The Worst First: Refrigerant Leaks

The refrigerant in your air conditioning system is quite literally the key to its ability to cool the air in your home. Your system has two coils—an indoor coil and an outdoor coil. The indoor coil is where refrigerant evaporates in your air conditioning system. This allows the system to draw heat out of the air in your home. Then, the system condenses the refrigerant in the outdoor coil. That allows heat to be released outdoors.

If your system is low on refrigerant, then it definitely could account for the warm air blowing from your system. If there isn’t enough refrigerant, then the system simply won’t be able to remove enough heat from the air in your home. It’s just that simple. We can find the leak, seal it, and replenish your system with a full refrigerant charge.

It May Be Another Type of Leak

The duct leak, specifically. If you use a central air conditioning system, then you use ductwork to distribute conditioned air throughout your home. And if you use ductwork to distribute conditioned air throughout your home, then you definitely don’t want that ductwork to be leaking!

If your ducts are not sealed up properly, then hot air can be pulled into them through the leaks. Once that happens, that hot air will warm up the air in the system, which will still be distributed throughout your home. As that warm air is distributed throughout the house, you’ll definitely start to wonder about the effectiveness of your home cooling system.

You May Have It Set Wrong

Let’s close with the best case scenario—you just set the thermostat wrong. We know, you think it sounds obvious. But trust us, it happens.

Your air conditioner has a fan-only mode. It is entirely possible that you set your air conditioner to fan-only and, as a result, it’s only running the fan! That won’t actively cool the air in your home, but you can resolve the problem with the flip of a switch.
