10 Signs Your Air Conditioner Needs Repair or Replacement

NCS coolingAir conditioning problems often arise at the most inconvenient times, particularly on excessively hot days when outdated or faulty AC systems are pushed beyond their limits. Ensuring a fully operational air conditioner is crucial for the comfort and well-being of your family, and this can be easily achieved through regular AC maintenance service. By promptly identifying minor issues, you can prevent expensive AC repairs or replacements. Familiarize yourself with the ten warning signs that indicate your AC unit requires attention:

1. Air Conditioning System is Blowing Warm Air

Nobody purchases an AC unit just for looks. Its main purpose is to keep your family comfortable during the hot and muggy summer months. If your air conditioner fails to blow out refreshingly cold air and instead blows out warm air, contact an HVAC technician for assistance.

2. AC Thermostat is Not Working

The thermostat is the command center of your air conditioning system. It communicates with the AC, ensuring it generates the right amount of cold air. If your air conditioning unit runs for short periods before shutting off or won’t turn on at all, this may indicate a problem with the thermostat. It’s best to have a trained HVAC specialist examine it due to the complexity of the electrical components involved.

3. Little Air Blows Out of Vents

Weak air flow can be a common issue. While you may feel cool air when you turn your air conditioner on, it may come out very weakly, making it impossible to circulate effectively in the room. This could be a sign of a failing compressor or a problem with the ducts. To determine the root cause, it is recommended to contact an HVAC technician for a tune-up. They have the necessary knowledge and experience to identify and address any potential bigger problems in the future.

4. Loud Noise Inside of the AC Unit

If you hear grinding, squealing, or scraping while the AC is on, it may indicate a problem with a belt moving out of place inside the unit. To avoid costly damage to other parts, it is advisable to contact an HVAC expert as soon as possible.

5. Strange Odors When AC Turned On

An air conditioner should not emit unpleasant odors. If it does, it indicates a problem. A strong smell may signify a burned-out wire inside the unit, while a musty smell may indicate the presence of mold in the unit or ductwork. It is crucial to have a professional diagnose this issue promptly, as it can impact the health of you and your family.

6. Insufficient Humidity Removal By the AC

Reducing the humidity inside your house is one of the essential functions of an air conditioner. Even in low humidity climates, the air retains a certain level of moisture. If you notice increased humidity while the air conditioner is running, it may be an indication that the unit requires repair.

7. Increasing Frequency of AC Problems

If your unit has required AC repair service three or four times within a few months, it might be time to consider purchasing a new one instead of investing in further repairs.

8. Coolant or Water Leaks Around Air Conditioning Unit

Any moisture leakage in or around your AC system is a cause for concern. It could be a sign of a refrigerant leak, which is hazardous due to Freon’s toxicity. In such cases, it is crucial to contact a professional immediately. In less severe instances, the moisture may be caused by a broken or blocked condensation disposal tube, resulting in water leakage. This issue can manifest in various ways, such as water leaking out of the HVAC system or ice formation on the copper refrigerant lines outside the condenser. In either case, it is recommended to reach out to an HVAC specialist.

9. Rising or High Electric Bill

If your energy bill starts to increase without any additional usage, it could be a sign that your AC system is not functioning efficiently. Possible causes for this issue include a broken thermostat switch, leaks in your HVAC system’s ductwork, or the age of your air conditioning unit. Regardless of the cause, it’s important to have your unit repaired.

10. AC Lifespan Is Over

If your air conditioning unit is at least ten years old, it’s time to start considering a new unit. Air conditioners typically do not last more than a decade. Recognizing these signs can help you address potential problems and possibly avoid the need for a complete HVAC unit replacement. Contacting a professional HVAC technician is recommended if you experience any of these signs. Handling repairs yourself can lead to additional costs if not done correctly.
