Help, My House Is Too Hot and the AC Isn’t Doing Enough!


No problem! It’s dilemmas like this that are the reason we’re in business. We can handle whatever AC repair in Little Rock, AR you need to have your household made cool once more. Our technicians will get to the root of the problem with your AC.

Before you call us for help, let’s take a closer look at why your home’s central air conditioning system is falling down on the job. If the AC is running and you feel cool air from the vents, but the house still feels stuffy and uncomfortable, there are several potential causes. Some you may even be able to correct yourself.

Check the air filter first

One of the most common sources of an air conditioner that isn’t working right is a clogged air filter. This filter is responsible for preventing debris in the return air ducts from getting inside the HVAC cabinet. After one to three months, the filter will become congested, and this restricts airflow. Without enough airflow, an AC cannot cool the same amount of air, leading to a drop in performance as well as other troubles. Check the air filter and put in a new one if it’s clogged. This might solve the problem. 

The thermostat may be misreading temperatures

Here’s another common issue for air conditioning systems: thermostats that are doing it wrong. A thermostat can become miscalibrated the same way a clock might start losing minutes, causing the thermostat to read the wrong temperatures in the house. If the thermostat registers the house is cooler than it is, it will shut down the AC before reaching your desired temperature. This is basic repair for our technicians: we can recalibrate the thermostat, or in some cases put in a new one if that’s a better long-term solution. 

The AC is short-cycling

Short-cycling is when an air conditioner isn’t completing a full cooling cycle but instead shutting off after less than 15 minutes, then turning back on again, then shutting down soon after, etc. Listen to how long your AC is running: if it’s too brief, the system is short-cycling and that accounts for why the house isn’t getting cool enough. Short-cycling is terrible on its own for the AC and there are multiple reasons for it. Our technicians can diagnose the source and have it repaired. 

The AC is over the hill

One of the signs of an air conditioning system that’s too old to do its job is when its cooling capacity starts to decline. The average service life of an AC is from 10 to 15 years, and if your system is in (or over) this range, it might be time to consider a replacement if it can’t keep up with normal comfort demands,

The AC is undersized

On the other hand, if your air conditioning system is brand-new but can’t manage the heat, it might have been poorly sized when installed. This is unfortunately common if amateurs did the installation. When an air conditioner is undersized, it won’t be able to meet standard cooling demands and will run and run as it tries to attain an unattainable temperature. You’ll need to have the system replaced—and have professionals do it.
