Does your AC make a strange noise during operation all of a sudden? Have you noticed that your energy bills have never been higher? Does your AC fail to respond to the thermostat adjustments? There are a number of things that can go wrong with such a large and complex system, and only a professionally trained technician can ensure that your cooling system is diagnose thoroughly and then fixed properly. Still, there are some common cooling problems worth mentioning, if only to help you identify that you have a problem in the first place. As soon as you notice something wrong, make sure you alert a professional. Catching the problem early on its development is the best way to avoid serious damage.
Keep an eye out for the following issues.
- Strange or loud noise. If your AC makes a sound that you’ve never heard before or it seems particularly loud all of a sudden, then there’s probably something wrong with it. Don’t hesitate to call on a professional to diagnose it. If it’s a grinding noise, your blower motor might have dried-out bearings; if it’s banging, then there could be a loose component somewhere within your air handler or ductwork.
- High energy bills. A spike in your energy bills can occur for a number of different reasons, but it’s always cause for concern. If you find that your energy bills are much higher than normal, then you likely have an efficiency issue such as an air or refrigerant leak. Low refrigerant can cause problems all over, and airflow issues do not go away on their own.
- AC fails to turn on. If you find that your AC fails to respond to your call for cooling, then it could be a problem with the capacitor, which is a small electric device responsible for jumpstarting your AC whenever you need to turn it on. You may also have a problem with your existing thermostat. Before you call, however, reset the circuit breaker and your thermostat to see if that takes care of the problem.
