One of the most frustrating things that can happen during summer is when your air conditioning unit suddenly malfunctions. It can be a real nightmare, especially if the temperature starts to creep upwards. Whether you're dealing with a clogged filter, a malfunctioning compressor, or issues with the thermostat, it's important to be able to recognize the most common residential air conditioning (AC) issues and understand how to fix them. This blog post will discuss the most common AC problems homeowners face, how to troubleshoot them, and when it's time to call a professional.
Low or Inadequate Airflow:
One of the most common AC problems is when your unit isn't producing enough cool air. There can be many causes of this issue, including clogged filters, dirty coils, and faulty motors. To troubleshoot this issue, you should inspect the air filter in your unit and clean or replace it if necessary. Additionally, check the AC's exterior unit and make sure there's no debris that could be blocking airflow. If the issue persists even after you've cleaned or replaced the filter and cleared the exterior unit, you may have a larger mechanical issue that requires a professional technician's expertise.
Another common AC issue is leaking refrigerant. You may notice this issue due to a hissing or whistling sound coming from your unit. Refrigerant leaks are problematic as they can cause a drop in your AC's performance and even environmental harm. To troubleshoot this issue, check for visible leaks and make sure your refrigerant is at the proper level. If you're unsure, it's best to call a professional.
Another cause of AC unit issues can be due to a faulty thermostat. If your unit isn't cycling on or off correctly, you may need to replace the thermostat. Before you do that, though, check if there are issues with the wiring. If you're comfortable working with electricity, you can troubleshoot and fix this issue. However, it's best to hire a professional if you're unsure.
Frozen Evaporator Coil:
A frozen evaporator coil is another issue that could cause your AC unit to malfunction. It's usually caused by dirty air filters or a lack of refrigerant. This issue can cause a significant drop in airflow and even water leakage. To troubleshoot this issue, turn your AC unit off and let the unit thaw naturally. Once you've done that, inspect your air filters and replace or clean them as required. If the problem persists, you may have a refrigerant leak, and you should call a professional.
