If your central air unit suddenly stops working, there are a few different reasons why this may be so. The good news is that you may be able to troubleshoot some of these issues yourself before you need to spend the money on a professional. However, some problems are more severe or are simply too complicated, and it’s best to call a professional rather than risk injury or damaging the system further.

If this second situation applies to you, our team of technicians at Ambient Edge is here for you. We have hours around the clock so that we can provide you with help when you need it the most. If you’d like to schedule a service call with us, then call us at (888) 240-8283, or send us a message via the contact form on our website.

The Thermostat

This may seem like a no-brainer, but if your central air isn’t working, double-check the thermostat. The thermostat tells the system what to do, and if it’s off, it can’t control anything. Thermostats can turn off if someone bumps into them, or if someone otherwise accidentally turns it off. Double-checking that the switch is in the “on” position, rather than the “off” position, can save you a lot of grief – and money on a service call.

If the switch is “on,” and your thermostat is programmable, then the issue may lie with its batteries. When replacing the batteries, make sure you follow the instructions in the manual. Putting the batteries in incorrectly can cause the thermostat to malfunction as well, and then you think the problem is not with your thermostat when it actually is.

A Tripped Circuit or Blown Fuse

Sometimes the reason the central air unit does not work lies with its power source. Check your circuit breaker box to ensure you do not have a tripped circuit, or your fuse box for a blown fuse. This is an easy enough fix, as all you need to do is flip the circuit back or replace the blown fuse. However, if this happens regularly, then you may have a more complicated electrical problem, which you should have a technician look at before it can escalate and potentially cause a fire.

The Condensate Pan Switch

The more humid it is, the more condensate your air conditioner will produce. All this water drains through the pipes, and the unit’s water detection switch prevents your home’s structure from experiencing water damage from the runoff. If your central air unit isn’t working, this may mean that the water detection switch activated due to excess moisture somewhere.

This is a situation that calls for an air conditioning professional. The technician can use a chemical treatment to unclog the pipe and can then provide you with suggestions on how to prevent similar clogs from forming in the future. You may also be interested in signing up for a preventative maintenance contract, which will allow us to inspect your system twice a year specifically to prevent problems like this from occurring.

The Air Filter

Some central air units come with a sensor that causes the system to shut down if the air filter gets too dirty. Some manufacturers design their systems this way to prevent their customers from breathing in dirty air that could be filtered throughout their homes. Be sure to check the filter and change it if necessary. You may discover your unit begins working again almost immediately after doing so.

Your Ducts

Perhaps the problem does not lie with whether your system is running but how effectively it is running. If your central air unit is on but the house does not feel any cooler, your problem may lie with your air ducts. If there are leaks or holes in your ducts, either from rodents or improper installation, then you’re paying for cold air to basically filter outside. You’re also causing your system to work harder, which can lead to its early demise – not to mention higher electric bills for you.

If it is inconvenient or difficult for you to check your air ducts for leaks, our experienced HVAC technicians can help.
