Fairfax, VA Air Conditioing Guide: What to Do if Your Air Conditioning Makes Strange Sounds

Do you hear a subtle hissing sound coming from your outdoor unit? Or perhaps a banging noise from your indoor air handler? If you’re unsure what do if your AC is making a strange sound, then you need only get in touch with your local Fairfax, VA air conditioning technician. AC’s are complicated machines, full of various electrical and mechanical systems and a wide variety of components. There are numerous things that can go wrong with your air conditioner, no matter what type or brand it is. In this post, we’d like to share with some explanation about what these sounds can indicate. While you should expect a certain amount of sound from your AC during operation, unusual or loud sounds that suddenly arise should be taken as an indication that something’s not right. Call OASIS Heating, Air Conditioning & Refrigeration, Inc. today for comprehensive air conditioning repair services.

  • Hissing: If you notice a hissing sound around your ductwork, then there’s probably an air leak in your ductwork somewhere. This will probably have to be professionally sealed in order to restore your lost energy efficiency and cooling performance. But if you hear hissing around your coils or compressor, then it could mean you have a refrigerant leak. This can cause serious problems with the operation of your AC, including compressor overheating.
  • Banging: If it sounds like there is a banging sound coming from your AC, there might be a loose part knocking around inside the system. Alternatively, there could be a damaged fan blade that is banging against another part of the system. This is probably causing significant damage to the interior of your AC unit, so you should get it fixed as soon as possible.
  • Grinding: This is a disturbing mechanical sound that may indicate a serious issue. Turn off your AC and call for professional repair. The bearings in your blower motor may have dried out, and further operation may cause serious damage.

We hope this gives you some idea about what sounds can mean for the operation of your air conditioner. Call OASIS Heating, Air Conditioning & Refrigeration, Inc. today for air conditioning repair services in Fairfax, VA.
