1. Rattling, Buzzing or Ticking

Switching on the thermostat should produce little more than a hum. Hearing a sharp rattling, a deep buzzing or even a constant ticking could simply mean there is a loose screw. It could also indicate a bigger problem, depending on the source of the sound.

Outside: The sounds could be a symptom of a bent fan blade.

Inside: Bangs and clangs inside the home could indicate a blown motor.

Calling an AC repair specialist to investigate the problem is the most efficient way to find a resolution.

2. Early Shut-Down

Do you hear the unit turn off before your home has reached the desired temperature? Many times, this occurs when a thermostat is placed either in direct sunlight or too close to a register. An air conditioning contractor can relocate the thermostat or troubleshoot another explanation for the malfunction.

3. The Sound of Silence

Turn on the unit: nothing. Turn it off and turn it on again: still nothing. Perhaps the worst sound your unit can make is no sound at all. The deafening sound of silence can be a huge blow as you stand sweating in front of the thermostat. Fortunately, this is usually due to a blown fuse or a faulty thermostat. If checking the circuit breaker and adjusting the temperature do not produce results, contact our repair company right away.
