6 Signs of an Air Conditioner Problem

6 Signs of an Air Conditioner Problem

Once again, spring has arrived and temperatures have started soaring through the Coachella Valley. Before the hottest days arrive, you'll want to make sure that your AC unit is in excellent condition and fully capable of keeping you reliably cool. At the first indication of AC trouble, you'll want to call in a reputable HVAC technician to conduct diagnostics. Here are six signs of AC failure.


When you notice AC-related leaks, it's important to be proactive about fixing them. This could mean that you've got a refrigerant leak, which poses a health hazard. With leaking fluid, another possible concern is a problem with your condensate drain line.

Doesn't Reliably Blow Cold Air

If your unit isn't blowing cold air, then you could be dealing with a thermostat issue. This could also be due to another problem, such as a dirty filter or failing condenser fan.

Weak Airflow

In some cases, poor airflow can be addressed by getting a professional ductwork cleaning. This will rid your air ducts of contaminants and make it easier for air to flow freely. However, this symptom could also mean there's a mechanical issue, such as a problem with the compressor.


If mold or mildew has built up in your AC unit or ductwork, then you may notice a musty stench. If you notice a burning odor, then there could be fried wire insulation. This poses a serious safety concern and means you should immediately shut down your system and call up an HVAC professional.

Spike in Energy Bill

As a malfunctioning AC unit struggles to keep the home cool, it may use more power in the process. Consequently, you could see an increase in your energy bill.

Strange Noises

A squealing sound suggests that there's a problem with the belt connecting the motor to the blower. Grinding sounds are also concerning and should be brought to an HVAC technician's attention.
