Air Conditioner Not Cooling? Here’s What to Check Before Calling for Repair
Are you experiencing issues with your air conditioner not cooling in Schertz, TX? You can sometimes encounter a situation where the thermostat shows one temperature, yet the room feels warmer and the summer heat continues to climb. This is an obvious sign that your AC is not cooling the house properly. While you may need to schedule professional repair services to overcome the problem, you may also be able to quickly diagnose and fix it yourself by performing a few simple checks. In this guide, we’ll look at the most common AC issues, what to look for, and how to know if it’s time to schedule repair services. If you have already checked the basics, call G1 Air for fast AC repair in Schertz.
Start With the Easy Checks
An air conditioner not blowing cold air could mean it’s time for thermostat repair or replacement. Check if your thermostat is set properly. Specifically, you want to make sure it’s set to Cool mode, that the fan is on auto, and that the temperature setting is at least a few degrees below the room temperature at which the AC should automatically turn on.
You should then shut your AC system off and check the air filter. A clogged filter blocks or restricts airflow, while failing ductwork may leak conditioned air, which can result in the AC running but not cooling or only producing minimal cool air. If it looks black, gray, or matted, air filter replacement may be all it takes to overcome the problem.
If your AC isn’t turning on when it should, you want to confirm that the system has power. That means checking the breakers, the disconnect switch at the condenser, and the float switch in the drain pan. The float switch will prevent the system from running if the drain pan gets too full to prevent water from leaking out. If the pan is full, it usually means that the condensate drain line is clogged. You can unclog the line yourself, but it often isn’t possible without professional AC services.
The last step is to look at the outdoor unit to make sure the coil isn’t clogged with debris or dust. A clogged coil can lead to significant performance issues or even prevent the system from cooling. If the coil looks clogged, shut off power to the system and then gently hose it down with low-pressure water to wash away the dust and debris.
Check for Airflow Issues Inside the Home
After performing the basic checks, make sure there are no issues that could contribute to weak, insufficient airflow. This includes checking that none of the supply registers are closed or blocked, that the return air grilles are clean and open, and that there isn’t any furniture, curtains, or other items covering the vents. The other thing to note is that excess interior heat from ovens, hot showers, and sunlight shining through windows can also make it nearly impossible for your AC to keep up at times.
Signs the Problem Needs a Professional
If you still can’t determine why your AC is not cooling your home, you may still be able to spot signs that indicate you need professional repair service. For instance, ice on the indoor coil or the refrigerant line means that the evaporator is frozen. In this case, shut the system off, let the coil thaw, and then make a repair call.
Another thing to watch for is any type of unusual noises like grinding, clicking, or loud buzzing. All of these sounds typically indicate a failed capacitor, a bad contactor relay switch, or a failed motor. If warm air is blowing while the outdoor unit is running, it usually means that the system is low on refrigerant, the compressor is beginning to fail.
A more serious concern is if you notice a burning smell or water around the indoor unit. In either situation, you should immediately turn the system off and call a professional to ensure no further damage occurs.
Short-Cycling
Short-cycling is when an AC system keeps shutting off before completing a full cycle. This often happens because of an electrical, sensor, or refrigerant-related issue. Short-cycling puts lots of additional stress and strain on the system, which can quickly lead to a major problem if you don’t act quickly.
