Prairieville Air Conditioning Service: How to Tell if My Residential A/C is Broken

It won’t take long to notice when your a/c stops working, especially during a Louisiana summer. However, just because your unit is not blowing cool air, it doesn’t necessarily mean that it needs to be repaired . There are several small problems that can cause your air conditioner to shut down that can be easily diagnosed and inexpensive to fix. Here are some of these common problems and how to fix them.

Problems with the Thermostat That Affect Your A/C Function

The thermostat is the device that triggers the air conditioner and is responsible for the temperature control in your house. If you have a digital thermostat, check to see if the face is blank. If it is, this can be a sign that your thermostat is no longer receiving power. Use a voltmeter to test the wiring and look for a short.

In the event that the wiring is providing power, your nextstep is to look for any blown fuses or circuits. Go to the fuse box or circuitboard of your house and look for fuses that are blown (no longer connected) and switches that have been flipped off. If these appear to be in working order, check the fuses on your air conditioning unit. Some units have onboard fuses and switches that can also malfunction.

If these all appear to be working but the face of your thermostat is still blank, it may be time to replace the thermostat. Some devices have a warranty, so replacement may be free depending on the device and its age.

The Thermostat is Working but I am Still Not Getting Cold Air. What Should I look for?

There are a few other problems you may want to investigate before calling a technician. One of the first would be to check your a/c filter, especially if you know that it has been more than a month since you changed it. If the filter becomes clogged, air will not circulate properly, and your home will have a hard time cooling down.

From there, you should see if the blower on your air conditioner is receiving power. Go to your thermostat and turn the fan on. If it does not kick on, then your blower is not receiving power. Try checking fuses and circuits to see if this is the culprit. Remember: these fuses or circuits can be on the breaker box in your house or on the unit itself.

The last thing to do is to check the condensation drain. If this is clogged, then your unit will shut off to avoid flooding or backing up further. Clear the drain to allow proper flow.

If none of these seem to be the problem or if you feel that a second opinion is needed, call Glaze Heating and Air to give you a proper diagnosis of your unit’s problems. We have years of experience serving the people of South Louisiana in HVAC repair and replacement.
