What Causes Your AC to Break Down?

Temperatures might soar during the summer. You turn on your air conditioner to get away from the heat, only to realize that it isn’t working properly. You may wonder what is causing the issue and what you can do about it. Here are three key reasons why your air conditioner may not be working properly and why you may need the assistance of a firm like John Henry’s Plumbing, Heating, and Air, which can provide AC repair in Lincoln, NE.

Temperature Regulators

One of the most common reasons customers call for AC repair is a problem with the thermostat. If the thermostat is set to “Auto” rather than “On,” the air conditioner will not turn on. Turn the switch to the “On” position to cool your home.

Check that the thermostat is set to the correct temperature. Seventy-eight degrees Fahrenheit is the ideal temperature. If it is set too low, your air conditioner will run continuously and may not cool your home enough. If it is set too high, the air conditioner will cycle off too frequently and will be unable to adequately cool your home.


To cool the air, your air conditioner uses refrigerant. If there is a leak in the system, the refrigerant will escape, and the air conditioner will not work properly. Evidence of a refrigerant leak, such as an oily deposit on the tubing, may be seen in rare cases.

If you suspect a refrigerant leak, it is best to have it repaired by a qualified specialist. Please do not attempt to repair it because it is dangerous and could endanger your health.

Condenser Issues

The condenser is the part of the air conditioner that aids in the cooling of the refrigerant. If your AC condenser is dirty or clogged, it will not work correctly, and your air conditioner will struggle to cool your home.

Unplug or shut off the power to the unit and use a hose to remove any dirt and debris from the condenser. If the coils are damaged, they must be replaced. Again, you’re best off leaving this to an experienced professional with AC repair experience.

Less Common Issues

Your air conditioner may also stop working owing to less common problems such as:

  • Fan concerns
  • Evaporator coil issues
  • Problems with the fuse or breaker

Evaporator coils help to remove moisture from the air. The air conditioner will not function properly if they are frozen. Because fans are in charge of circulating air across the coils, they can also cause your air conditioner to cease working.

Finally, faulty breakers or fuses might cause AC problems. When a breaker is tripped or a fuse breaks, power is removed to the unit, rendering it inoperable.

What Should I Do If My Air Conditioner Has Stopped Working?

If your air conditioner stops working, there are a few steps you can take to resolve the issue. Check the thermostat first to ensure that the default settings are not preventing your air conditioner from cooling. Clean the condenser coils and remove any accumulated debris.

If you’re not sure what’s causing your air conditioner to stop working, the best thing you can do is call a professional. Call John Henry’s Plumbing, Heating, and Air today for more air conditioning assistance or to schedule an air conditioning repair in Lincoln, Crete, or Waverly, NE.
