Air conditioners are more advanced today and operate more quietly than outdated models. Newer units have sound-dampening technology and variable speed compressors designed to operate quietly and keep noise low. Some air conditioners make a specific sound when starting up or at the beginning of a cycle. If you notice abnormal noises coming from your air conditioner, however, know when it’s a big or small problem. Certain noises call for immediate action from a qualified HVAC technician.
Ignoring the different noises your air conditioner makes can be fatal to your unit, leading to complete breakdown in the future, which could be fatal to your bank account! Estes Services has qualified and experienced HVAC technicians to inspect and service your air conditioner. Our NATE-certified technicians will know what to do regardless of what type of noise you hear and ensure your unit returns to operating smoothly.
Buzzing Noises
A buzzing noise heard from the outside air conditioning unit can mean any number of problems, including debris in the unit, loose parts or the filter needs changing. If you hear buzzing noises, and it’s not an angry horde of bees, call Estes Services as soon as possible to investigate what is causing the noise. (Seriously, even if it is bees, call us. We’re happy to refer you to the appropriate solution, regardless of the problem). Leaving the symptom undiagnosed and untreated might cost you a fortune in the future to repair.
Banging Noises
Banging noises coming from your air conditioner indicate something might be loose or broken in your unit. It could be a piston pin, crankshaft or connecting rod banging around inside the compressor. Even an unbalanced compressor or a compressor asking to be replaced can produce banging noises.
Clicking Noises
Electrical parts can begin to click when an air conditioner starts up and shuts down. Constant clicking is not normal and may point to a defective control or failing thermostat. There are many electrical components in your air conditioner, which require preventative maintenance to catch problems early on.
Clanking Noises
Clanking noises indicate a component is out of balance or loose within the air conditioner somewhere. The compressor might be loose, or components within the sealed unit might have failed, requiring a replacement part. A qualified technician will know if the clanking is from a broken component or if the fan blades are unbalanced. These problems need to be addressed immediately to avoid bigger problems down the line.
Screaming Noises
High-pitched screaming noises are never a good sign. In an air conditioner, too, it’s a major warning sign. Turn the air conditioner off immediately and call Estes Services right away. The normal cause of such noise is a refrigerant leak, which can damage the unit and harm your family’s health. Screaming noises can also signal high internal pressure in your compressor, which can be extremely dangerous. If your unit turns on and then off, it means the sensor is still working, just don’t wait too long before seeking help for the screaming noises.
