One of the things you’ll see us talk about quite often here on our blog is how important it is to stay on top of air conditioning maintenance. This service helps reduce the frequency of large repairs by allowing us to fully inspect and adjust your system regularly. However, no matter how well you take care of your AC system and keep up on those tune-up appointments, there may still come a time that you need professional San Antonio, TX AC services—namely, repairs.

The last thing you want to do is be surprised when you turn on your cooling system for the first time during the year only to discover it’s not working. So, we suggest turning it on now, if you haven’t already turned it on this year, and taking it on a “test run” of sorts. Pick a cooler day or evening, and turn it on to both look and listen for any faults. Keep reading to learn more about some of the signs of an AC system in disrepair that you should watch out for.


This is the process that an AC goes through when its compressor turns on and off rapidly over a short period. This means that the cooling system isn’t completing its cooling cycle. One of the most common reasons this occurs is because it’s too large for the home it is installed in to begin with.

However, there are other reasons short-cycling can occur—a malfunctioning thermostat, leaky ducts, or stress on the compressor. All of these can lead to an early system breakdown and require professional services from experienced HVAC technicians.

Low Airflow

Walk through your home as your cooling system is running, and check each of the room vents. Is there sufficient airflow coming from them? If one or more vents seem sluggish, then something is probably wrong—either in the vents themselves or with the air conditioner’s air handler.

Hot Spots

It’s a good idea to test your air conditioner on a moderately warm day, as this will allow you to more accurately assess if you have hot spots in your home. These are pockets of warm air from your air conditioner not adequately cooling the home. Check to ensure your room vents are open, unobstructed, and have proper airflow. If the vents don’t seem to be the issue, then it is time to call in the pros.

Odd Noises

You shouldn’t hear unexpected sounds coming from the indoor air conditioner cabinet or the outdoor unit. Grinding, shrieking, and other mechanical sounds can mean that motors are wearing down and need repairs before they need replacements. Clanging and rattling noises could be loose parts, and a hissing noise indicates a dangerous loss of refrigerant through leaks. You as the homeowner are the most likely to detect unusual noises, as you are likely used to the everyday sounds of your cooling system. So if something seems off, don’t hesitate to contact our professionals.
