Whether your air conditioner has just broken down or it simply does not work the way you expect it to, it’s time to call in a technician ASAP. That is, unless you can solve the problem on your own. We do not recommend making any major repairs to your air conditioner. Without the proper training, you could injure yourself or make the problem with your air conditioner worse—and spend more than you need to correcting the problem.
However, we often show up to repair an air conditioner that really isn’t broken. The problem could have been fixed in a couple of simple steps, by double-checking the thermostat, or by a simple change in habits. So what can you do to try resolving a central air problem?
