When a Cooling System Won’t Cool

cooling-system-wont-coolWith temperatures already heating up, there’s no denying that summer is on its way. And when it hits here in earnest, you’ll be grateful for an air conditioner that functions effectively and efficiently. But what if yours isn’t doing its job?

Summer is without a doubt the worst time for your AC system to accumulate problems, of course. But unfortunately, it’s usually when issues are most likely to arise. And a drop in cooling output is one of the first signs that something is amiss with your air conditioner. Should you notice this, be sure to give us a call for professional Kaysville, UT air conditioning services, and in the meantime, read below for some reasons why this might be occurring.

Leaking Refrigerant

Most homeowners don’t realize just how vital refrigerant is to the functionality of their cooling system. Your AC system evaporates refrigerant to absorb thermal energy from the air in the ducts. The refrigerant gas then travels down the line to the condenser coil outside, where it’s condensed back into liquid, to vent the collected thermal energy outside of the home.

Refrigerant is something that does not normally deplete, so if you are losing any it means that the system has a leak. As the refrigerant level drops, so will your system’s cooling output. And eventually, your AC will shut down if the source of the leak isn’t found and repaired.


Short-cycling is a process that happens when your AC system turns itself on and off every few minutes. The most common reason this happens is because the air conditioner is too large for the home it’s installed in, but there are other reasons this might occur. For example, you could have a short between the thermostat and the air conditioner, causing the AC to receive the wrong signals.

Short-cycling can also occur due to a problem with the compressor, which is partly responsible for the operating rhythm of your cooling system. If short-cycling occurs for a prolonged period of time, then your cooling system will wear down much faster than it otherwise would, making problems happen more frequently.

Air Handler Problems

If your cooling system just isn’t circulating enough air, the problem is probably located in your air handler. This is the part of your air conditioner that’s responsible for circulating air through your home during operation. It is comprised of a large motor, with a fan attached to it. Moving that much air creates strain for the air handler, which can create issues.

The air handler includes bearings, which help it run more smoothly. But even those need to be replaced on occasion. If you notice a loud grinding sound accompanying the lowered cooling output of your air conditioner, then you probably need your air handler checked. If this AC component is malfunctioning, then it simply won’t be able to circulate air throughout your home properly, resulting in lower output.
