Tips For Troubleshooting Your Central Air's Uneven Cooling

Posted on

When the summer heat reaches its peak, you might find that you have one room in your home that's constantly warmer than all the rest despite your air conditioning system. If this is the case for you, you don't have to settle for uneven and insufficient cooling. In fact, there could be many reasons why your air conditioning isn't getting enough cool air to that one part of the house. A little bit of basic troubleshooting can help you narrow down the potential cause of the problem. Here's a look at some of the things you should check before you call your air conditioning technician.


Check the vents in the room in question to be sure that they aren't blocked or obstructed by a rug, curtain or furniture. Your air vents need a clear path to the room for the most effective cooling. Also, make sure the vents are open, because closing the lever on the vent prevents any air passage.

Air Circulation

If the room in question is always a bit stale and lacking in general air circulation, you'll want to think about installing a ceiling fan. While the ceiling fan may not physically cool the room, the improved air circulation may help the cooler air conditioning distribute through the room more efficiently.

Other Vents

One of the things that many homeowners don't realize is that central air conditioning is designed to be at its best with full air volume throughout the house. This means leaving all of the vents open in each room and the doors open to allow air to circulate throughout the house. Ensure that all of the vents and doorways are open to help the cooler air reach the more obscure places and keep things cool.

Air Ducts

Your air duct system is another key area where problems can lurk. If the air ducts are dirty or clogged with debris, it can hinder air flow and lead to warm spots in the house. The best way to eliminate this as a possibility is to call an air conditioning contractor to inspect and clean your entire air duct system.

While you're at it, have them inspect the ducts for air leaks. If your air ducts are leaking anywhere in the house, that's a significant cause for concern because you're likely losing a lot of the cooling benefit of the air from your air conditioner. If the leak is in the section of duct work right before the warm room, that could be why you're having trouble. There are many ways to deal with leaky air ducts, from professional duct sealing to taping the leaky areas.

Home Insulation

Your home insulation is another key area where cold air can be lost. Your home should be insulated sufficiently to prevent cold air loss from any room. If your insulation in the attic is poor or you never fully insulated it, that's a good reason for uneven cooling in the house.

Room Position

In many cases, homeowners find that the warmest room in the house is also the one on the upper floor that's south-facing. If the warmest room in your house is on a south-facing wall, close the blinds or pull the shades during the day to keep the sun out. This will help keep the room significantly cooler.

As you can see, there are many things that can contribute to having uneven cooling or warm rooms in your house. With the tips presented here and the troubleshooting support of your air conditioning and maintenance technicians, you'll be able to identify the source of your efficiency problems and get the system back on track.
