1) The AC Isn’t Cooling

If your air conditioner is running but not cooling, verify that the exterior unit is getting enough air circulation. Remove the lid if necessary to clean the condenser coils within.

You could also double-check your filter. It’s time to replace it if you can’t see light through it when you take it out. This may provide your air conditioner with the necessary cooling power.

If it hasn’t cooled by this point, give us a call and we’ll send out a Schaumburg air conditioning repair pro to fix it.

2) The AC Won’t Turn On

Start with the fundamentals if your air conditioner won’t turn on at all. Check that it is plugged in. Then, inspect your furnace room and ensure that your furnace fan is turned on. This switch is commonly mistaken for a light switch and is easily turned off by accident.

If this does not solve the problem, check your circuit breaker or fuse box. Check that the appropriate circuits or fuses are operational. Finally, double-check your thermostat to confirm that it is correctly adjusted. You might try lowering it by 5 to 10 degrees to see if that helps.

If your air conditioner still won’t switch on, it’s time to bring in a technician to troubleshoot the problem.

3) The AC Makes Odd Sounds

Try to figure out what type of sound you’re hearing:

  • A screaming noise will be made by the fan motor or the compressor
  • A buzzing sound is produced by faulty electrical components
  • Thumps, bangs, rattling, and other similar noises typically signal a problem with the blower or motor
  • Hissing often indicates a refrigerant leak

If you’re not confident in diagnosing and repairing the problem yourself, hire a professional to determine why your AC is making strange noises.
