Is your air conditioner running for a few minutes, turning off for a couple of minutes, and tuning on again? This is a common problem that people face with their air conditioners, especially in San Antonio.
The higher temperatures here can put a lot of pressure on your unit and create issues that lead to short cycling. A short cycling AC can be a very costly problem for you to deal with. If you keep running your AC despite the short cycling, it could end up with you receiving a much higher electricity bill, uncomfortable temperatures, and expensive repairs.
We will discuss some of the most common reasons why your AC keeps turning on and off. Recognizing the reasons will help you understand the importance of calling professionals in for repairs. As always, if you need any HVAC service in San Antonio, you can call us.
Reasons Your AC Keeps Turning On and Off
Here are some of the common reasons your AC keeps short cycling.
1. Bad thermostat placement
A common problem that causes your AC to begin short cycling is relatively easy for a professional to resolve. Your thermostat could be placed in the wrong place, and that can cause it to begin sending the wrong command to the HVAC system.
Ideally, you should place your thermostat in a central location, away from windows and air vents. If your thermostat is near an air vent, it can trick your unit into thinking that the home is cooler than it is. The result is that the thermostat will instruct your HVAC system to turn off.
Similarly, placing your thermostat near a window could make the thermostat detect hot temperatures even when the overall temperature is ideal. That can result in the thermostat turning on your HVAC more often than it needs to.
2. Clogged air filter
Another reason your AC could keep turning on and off is that the air filter could be dirty. A dirty airflow reduces or blocks the airflow to your air conditioner. Eventually, it can lead to the condenser coils freezing up and shutting down the AC far earlier than it should. The thermostat will turn on the AC again, and the cycle will keep happening, overworking your AC.
3. Refrigerant leaks
Refrigerant leaks are a very common reason for several AC problems. If your AC is low on refrigerant, it can cause the condenser coils to freeze up. That causes the air conditioner to turn off prematurely, and the thermostat turns it on again after a few minutes.
4. Dirty condenser coils
Dirty condenser coils can also cause short cycling in your AC. The coils are there in the external unit of your HVAC. These coils are responsible for dispersing the heat that the refrigerant bring from inside your home and allowing it to continue the cooling cycle. A dirty condenser coil can quickly overheat, causing your unit to struggle and short cycle.
