How to Fix a Squeaking Air Conditioner

As the weather starts getting hot in Alexandria, VA, it’s an unwelcome surprise to turn down the thermostat and find that your AC is making a weird noise. AC squeaking can be a cause for concern, especially if you’ve taken all the right steps to clean and prepare the unit for the summer. Read on to learn about the causes of this problem and how you can fix it.

Usually, AC squeaking is the result of a harsh winter in Alexandria, VA. If you’re experiencing these strange noises coming from your unit in the spring, it’s likely that sensitive components have been exposed to snow, ice and cold winter weather. It’s best to have a professional HVAC technician take a look at your system to get an accurate assessment of the problem. Generally, a squeaky AC can be the result of the following problems with your unit:

  • Winter weather problems: Cold weather takes a toll on an outdoor air conditioning unit. There are several issues that can occur due to winter weather, including damage to coils from falling icicles, coil fin damage caused by precipitation and problems with internal components if ice has made its way inside the unit. If you suspect that your system has suffered harmful effects from winter weather, contact a local HVAC technician to come take a look.
  • Condenser fan bearings: If you have a newer air conditioning system, you likely have a direct-drive motor with no belts. These units draw air across condenser coils by using a fan. If you’re hearing the squeaking or squealing coming from your outside unit, the most likely solution to the problem is replacing the fan motor. This is a tough fix that always requires the expertise of a trained HVAC technician in order to avoid further damage to the unit’s compressor.
  • Belt system: If you have an older air conditioning unit, it’s most likely belt driven. It’s not uncommon for these belts to wear out over the years. While you can try to replace the belts yourself, it’s generally not recommended, since it’s easy to damage a unit with incorrect repairs. Rely on an expert technician to get the job done quickly without damaging sensitive components of the system.
  • Overworked system: One of the reasons your air conditioning unit might be squeaking is that it’s working too hard to cool your house. More specifically, it’s working too hard to lower your humidity levels indoors. You could upgrade to a more efficient air conditioning system or invest in a whole home dehumidifier to improve the efficiency of your air conditioner and keep you more comfortable indoors.

Your air conditioning system plays a leading role in maintaining comfort during an Alexandria, VA summer, and if your AC is making a weird noise, it’s best to rely on a professional technician to diagnose and fix the problem. Call A Action Home Services whenever you notice strange sounds coming from your air conditioning unit—it could make the difference between a simple repair now or a more complex and expensive one in the future.
