Common Central Air Troubles To Watch For

Especially for homeowners who are fairly new to dealing with central air conditioning, sometimes the most common problems can be the most baffling. You can take a lot of the mystery out of air conditioner performance issues when you familiarize yourself with some of the most common malfunctions and signs that your unit needs repair. In fact, with summer in full swing, the time has never been better to learn what you should be watching for. Here are some of the most common issues that you might encounter with your central air conditioner.

Thermostat Malfunction

The thermostat connected to your central air conditioning unit is what sends the signal to the unit to run when the temperature in the house is higher than the thermostat temperature that you've set or programmed. 

If it's over the programmed temperature in your home but your air conditioner isn't turning on, or it's below the programmed temperature and your air conditioner isn't turning off, those are both signs that there's a problem with the thermostat. It could be a calibration problem where the thermostat itself isn't reading the temperature properly, or it could be a communication problem where the air conditioner isn't receiving the signals from the thermostat.

In some cases, if the air conditioner isn't turning on at all, it could simply be that your thermostat needs new batteries. The digital, programmable thermostats typically rely on battery power, so check this first. Otherwise, reach out to an air conditioning repair technician to narrow down the problem.

Water Leaks And Drainage Issues

Air conditioner operation results in moisture being drawn out of the air that passes through the unit. That moisture is drained out of the air conditioner through the condensate drain line. However, sometimes that drain line gets clogged or blocked from the outside. When that happens, the moisture can't drain out of the air conditioner and you end up with a backup of water in the condensate tray and the air conditioning unit. Ultimately, that water ends up leaking out of other areas in the air conditioner, potentially causing water damage and damaging the air conditioning components.

If you notice that your air conditioner is leaking, you should reach out to an air conditioning repair technician right away. They can check and clear the condensate drain line, remove the water accumulation before it causes mold issues and other damage, and restore the proper operation of your air conditioner.

Airflow Problems

One of the biggest problems that your air conditioner can have is a problem with the flow of air through the unit. There are a number of things that can cause airflow problems, some easier to address than others. If you notice that your air conditioner doesn't seem to be putting out near as much air as it used to, there are a few possible culprits.

Check the unit's air filter first. A dirty filter will inhibit the flow of air into the condenser unit. This results in less air flowing out as well. Your air conditioner's filter should be changed or cleaned regularly to avoid this. If it's not the filter, it could be a problem with the circulation fans inside the condenser unit.

Fans cycle the indoor air over the evaporator coils and the condenser inside the air conditioner. This air cycle is essential for cooling. When one or both fans are either not functioning or functioning improperly, it reduces airflow. Ignored, this can result in burning up the condenser and needing a whole new air conditioning system.

If you have any reason to suspect that the fans inside your air conditioning unit aren't running like they should be, reach out to an air conditioning repair technician right away to address it.
