It is important not to put off AC repair in St Charles Missouri, if you want to keep your home at a comfortable temperature over the summer months. But how do you know when it is time to call in a technician? Sometimes, it is very obvious if there is a problem with your air conditioning system, but there are also times when the issue is very subtle. Knowing how to spot potential issues at an early stage means that the problem will not escalate and become more costly to fix.

To check if your air conditioner is functioning as expected, use the thermostat controls to switch the unit on. Listen very carefully and take note of any noises which are unfamiliar. In particular, you should listen for knocking sounds or squeaking noises, which can indicate a problem with the belt or the motor. Sometimes these elements just need lubrication rather than replacement, but it is best to call in a technician to get an expert opinion and to ensure that the job is carried out properly.

You should also check the effectiveness of your air conditioning by taking the temperature in each room. If the system is working efficiently, the rooms should be of a similar temperature. Allow the thermometer a few minutes to adjust, to get a more accurate reading. You also want to check that the thermostat on the air conditioning unit and the temperature readings you have taken in the rooms match up. If there is significant disagreement, have your AC unit serviced. There may be a minor issue developing, or the thermostat might be faulty.

The final check you should make is to look for water dripping around the unit, or any formation of ice crystals. This is a clear sign that the air conditioning unit is not cooling the air effectively and is in need of repair. This is a job which always needs professional attention. If there are cracks in the tubes, then they will need immediate replacement. Pools of water may also indicate a serious problem with the condensation pump, which should remove excess water to the drain.

If you are in any doubt that your air conditioning system is working correctly, you should call in a professional to take a look at it. In the long term, you will be saving money as problems are easier to resolve in the early stages.
