Why Does My Air Conditioning in Charlotte Keep Getting Louder?

Posted by Chris Allen

Modern air conditioning units are designed to minimize their noise, and proper installation can further dampen the sound by placing the outdoor unit in an advantageous location. But sometimes, the noise persists, and if your air conditioning unit keeps getting louder, you may be looking at a problem in need of solving. In Charlotte, air conditioning issues require prompt attention, especially in the summer when the temperatures climb. A loud noise could be caused by one or more of the following.

  • Unusual noises could result from a number of different conditions. A bent or damaged fan unit may rub up against other components in the system, creating a loud rattling noise. Similar noises can be heard if sticks or twigs get caught in the vent and the fan scrapes up against them.
  • Air conditioning systems contain motors for the blower fans, the compressor and similar components. If the motors become stressed or damaged, they may make an increasingly loud noise as they overheat.
  • Buzzing or crackling sounds might take place in the event of an electrical malfunction; especially at the connections and compressor relay switches.
  • Loose hardware, unattached bolts or tools in the system can cause a rattling noise, as can improperly secured fans or motors. The rattling noise may get worse if the issue isn’t addressed.
  • Leaks in the refrigerant lines, doctor, or elsewhere may result in a whistling or hissing noise. Refrigerants my also make a bubbling noise in the event of a leak.

In addition, the ductwork used by most central air conditioning systems might amplify or enhance certain sounds coming from the AC unit, making it difficult to ascertain the source. No matter what it sounds like, however, it indicates a problem that should be addressed before you continue to use the air conditioner. Turn off the unit and contact a professional technician as soon as possible.
