Air Conditioner Troubleshooting Guide

Like most homeowners, you rely on your AC unit to keep you cool during the summer. This is when you need your system to be operating in peak condition. Unfortunately, some air conditioners can experience hiccups. Your AC system may at times break down unexpectedly and leave you feeling stranded. It is advisable to let a professional technician handle any mechanical failures. However, there are certain simple steps you can take to troubleshoot your own equipment. These steps are easy to follow and could swiftly return your unit to top shape.

AC Will Not Turn On

One of the most common problems you are likely to experience is an unresponsive AC unit. In this case, your AC will not activate to begin the cooling process. Such a problem usually stems from underlying issues with the thermostat. Make sure that your thermostat is not faulty or broken. Additionally, you can try to change its setting to see if the situation improves. Ensure that the device is set to “cool” and not ”heat.” This may seem obvious, but it’s easy to overlook simple settings on a thermostat. Another issue to look at is the circuit board. Ascertain that the circuit breakers are working properly. If the circuit breakers are not in the “ON” position, your unit will not activate. Consider letting an expert technician handle your electrical components for safety reasons.

AC Not Cooling

If your unit turns on but does not cool, you should look at the thermostat. Usually, the issue emanates from an incorrectly set thermostat. Change its setting to make sure that the unit cools your surroundings. If you believe that the thermostat is working properly, look at air vents to make sure that they are not blocked. Clogged vents will make it difficult for your unit to spread cool air into your home. Here are a few other issues that clogged air vents can cause:

  • Polluted air
  • Noisy unit
  • Poor airflow
  • High electric bills
  • Lower energy efficiency

AC Blowing Hot Air

In the event that your AC system is blowing warm air, you should inspect the outdoor unit. If the condenser is blocked, it is likely that the air vents will emit warm air. It is also possible to pick out foul odors from the unit. Clean your condenser to avoid the buildup of dirt. Use a hose to gently remove any unwanted particles and debris. If the condenser is completely covered by a thick layer of dirt, consider contacting a professional for deep cleaning procedures. Moreover, do not forget to check the thermostat for any issues with the setting. In some scenarios, you may have accidentally left the thermostat in heating mode hence the hot air coming out from the air vents.

Strange Sounds

A noisy AC unit can indicate a myriad of problems. One of the most common issues is clogged ductwork. If the ducts of your unit are blocked, your equipment will struggle to bring cool air into your home. This may in turn lead to high utility bills. Another cause of the noise could be a faulty blower. This problem usually produces a loud screeching sound—as of metal rubbing against each other. Make sure to tighten all components inside the unit to make sure that there are no loose parts. You may want to have a professional handle this part. Moreover, the issue could have originated from a bad compressor. Furthermore, clear your unit’s air vents to ensure that they are not clogged. Any blockage may also produce unwanted noises.
