Why Does My Air Conditioner Click?

Home heating and cooling systems make noise.  Even the top of the line “quiet comfort” units will hum, or buzz when they’re doing their job.  Your ductwork may accentuate these sounds, adding rattles and vibrations as your system engages and blows air through your vents.  These sounds are a normal part of your system’s operation and shouldn’t be cause for alarm.

On the other hand, if your system is making unusual noises, or sounds that are unfamiliar and you, the homeowner, don’t associate with normal operation of your cooling system, it may be time for a service call.  Some of the sounds emanating from your system, as it comes on, or as it cycles through the cooling process, could indicate a potential problem with your air conditioning.

Causes of AC Clicking

One of the more common, but troublesome, sounds your cooling system may make is a clicking sound.  Noticeable AC click sounds can be indicative of potential problems in several of your cooling system components.  In order to be certain, you will need to contact Air Plumbing & Heating for an AC inspection, however here are a few common causes why your AC clicks:

  • Clicking noises as your unit turns on or off can be caused by a loose fan, or a faulty relay switch.  Frequently, when a fan becomes loose, from average wear and tear, or lack of maintenance, it will hit against something in the condenser.  When this happens, typically as it starts up or slows down, and sometimes continually as it operates, your AC will make a clicking sound.  Check your unit and see if the sound is coming from the fan.  Otherwise, your relay may not be working properly.
  • If your system doesn’t turn on at all, other than a steady click, say every 20 seconds, this can indicate a faulty control board, fan motor, capacitor, or switch.  Contact Air Plumbing & Heating immediately, as any delay, or attempts to fix the problem yourself, could end up in the need for a whole new unit.
  • If your AC is running continually, with intermittent clicking, the likely cause is a malfunctioning thermostat.  Thermostats wear out over time, wires come loose, or short out, and can cause undue stress and strain as your “confused” air conditioner struggles to keep up.   Even though a thermostat can be an easy fix, a service call is worthwhile to assess any potential damage caused by non-stop running.
  • A clicking or ticking sound, accompanied by rattling and shuddering, can be caused by problems with your compressor.  In order to avoid the need for a completely new system, contact Air Plumbing & Heating and schedule an immediate service call.  Your compressor is one of the major components of your air conditioning system.  Any noise that comes from your outside, or inside, unit itself can indicate an impending breakdown of your cooling system and should be urgently addressed.

Should your AC click, or make unusual sounds while cooling your home, count on the experts at Air Plumbing & Heating.  Our technicians will come to your home, inspect your AC unit for problems, and, in most cases, service and repair then and there.  You and your family will be chilling in the comfort of your air conditioned home in no time at all.
