AC Repair in Bolingbrook, IL: Signs You Shouldn’t Ignore

By Eco Temp HVAC February 15, 2024



During the scorching summer months, an air conditioning unit becomes your best ally in maintaining a comfortable indoor environment. Nonetheless, as with any appliance, your AC unit may experience issues that require prompt attention. When ignored, these signs can lead to more serious problems and discomfort. Here, we will highlight some of the most essential signs indicating the need for AC repair in Bolingbrook, IL.

1. Weak Airflow:

• The presence of a weak or inadequate airflow is one of the first signs that your air conditioning system requires attention.
• Air filters that are clogged or dirty can reduce the flow of air. When changing the filter fails to resolve the problem, it is time to seek professional assistance.
• Alternatively, poor airflow may indicate problems with the blower motor or ductwork, which a technician can diagnose and resolve immediately.

2. Unusual Noises:

• Make sure that you are attentive to any unusual sounds coming from your AC unit. Squeaking, banging, or grinding noises should raise your suspicions.
• Squealing sounds may indicate belt problems, while banging may indicate a loose or damaged part. Grinding noises may indicate bearing problems.
• You should not ignore these sounds as they can result in further damage and more expensive repairs.

3. Warm Air Coming from Vents:

• Whenever warm air is blowing out of your vents, it clearly indicates something is amiss.
• Refrigerant issues, a malfunctioning compressor, and thermostat problems are all potential causes. These problems must be addressed as soon as possible to avoid a complete system breakdown.

4. Frequent Cycling On and Off:

• A correctly functioning air conditioning system should cycle on and off to maintain a desired temperature. However, if you notice frequent or rapid cycling, this may indicate that there is a problem with the system.
• A professional inspection can identify the cause of this problem and provide an appropriate solution, such as a malfunctioning thermostat, dirty condenser coils, or low refrigerant levels.

5. Water Leaks or Moisture Around the Unit:

• Observing moisture around your air conditioner is abnormal and may indicate the presence of a refrigerant leak.
• The presence of leaking water can also indicate a blocked or disconnected drain tube, leading to potential water damage and mold growth. Addressing these issues as soon as possible minimizes further damage to your home and maintains the quality of the indoor environment.

6. Unpleasant Odors:

• An AC vent emitting foul or musty odors should be investigated.
• Mold or mildew growth may cause these odors within your system or ductwork. Ignoring this issue may not only cause poor indoor air quality, but it can also compromise your health. Professional cleaning and maintenance can eliminate the source of the problem.

7. High Humidity Levels Indoors:

• AC systems play an important role in regulating both temperature and humidity levels. If you notice an increase in humidity despite your AC system operating, then there may be a problem.
• A malfunctioning compressor or inadequate system size may be contributing to high indoor humidity. Addressing these issues promptly will ensure that your air conditioning system operates efficiently and maintains a comfortable atmosphere within your home.

8. Visible Ice on the AC Unit:

• If you observe ice accumulation on your AC unit, it’s a sign of trouble.
• A common cause of ice formation is inadequate refrigerant levels, restricted airflow, or issues with the evaporator coil. Do not allow the ice to persist, as it can cause extensive damage. Turn off the air conditioner and call a professional to prevent further damage.
