Troubleshooting a Central Air Conditioning System
When the weather warms up and it’s time to turn on your central air conditioning unit, you may run into problems that keep your air from turning on or working properly, especially after several months of inactivity. Common problems can often be solved through a few steps of troubleshooting, but if the problem proves to be more complex or serious, then you’ll want to call an HVAC professional.
Troubleshooting According to the Problem
If your air conditioner won’t turn on, start with the basics. First, make sure there is power to your AC unit. Have any fuses blown or the circuit breakers tripped? If so, replace the fuse and reset the breakers. If not, check your outdoor unit and the blower motor to make sure the switches are set to “on.” Next, check your thermostat. Make sure it is on and set to “cool” at an appropriate temperature, or try lowering the temperature by five degrees. If your air conditioner still won’t turn on, you might have a faulty motor or compressor. In that case, call an HVAC professional.
