10 AC Warning Signs to Keep Watch For
We at Absotemp Climate Control Inc. are often asked what the most common causes of AC repairs are. There are many reasons your AC is not operating as it should. Each requires a specific fix and the proper expertise. In this post, we will discuss the 10 most common signs your AC needs repairs, and why Absotemp Climate Control Inc. is the HVAC company to call if you’re in the Oakland County area.
1. Warm or Weak Airflow
If you notice that lukewarm air is coming from your vents or that the airflow feels incredibly weak, your system is struggling.
- Possible causes: A clogged air filter, a failing blower motor, or low refrigerant levels.
2. Strange Sounds
Your air conditioner should run relatively quietly. Any new or loud noises are a red flag.
- Grinding or Squealing: Often indicates a failing motor or worn-out belt/bearing.
- Banging or Clanking: Can mean loose internal parts, such as the compressor or fan blades.
3. Foul Odors
Unpleasant smells coming from your vents should not be ignored.
- Musty: Indicates mold or mildew growth inside your ductwork or unit.
- Burning: A strong burning smell suggests an electrical component or wire is overheating.
4. Frequent or Constant Cycling
While AC units turn on and off to maintain a specific temperature, constant on/off cycling (short cycling) or continuously running without ever shutting off indicates a deep-rooted issue.
- Possible causes: Faulty thermostat, refrigerant leaks, or a dying compressor.
5. High Humidity Levels
Your AC should regulate moisture. If your home suddenly feels sticky, muggy, or damp while the AC is running, the system’s dehumidification capability is likely compromised.
6. Water Leaks or Ice Buildup
Moisture, pooling water, or ice on the refrigerant lines around the unit are serious signs of trouble.
- Possible causes: A blocked condensate drain or a refrigerant leak, which can damage both the unit and your home.
7. Spikes in Energy Bills
If your cooling habits haven’t changed but your monthly utility bills have mysteriously jumped, your system is likely losing efficiency and working harder than it should.
8. Struggling to Keep up With Demand During Summer
This means your system isn’t operating at full capacity. There could be many reasons for this, so it’s best to schedule a system inspection. Depending upon the issue and age of the system, replacement may be necessary.
9. Unit Won’t Start
Causes for this include a bad capacitor, broken thermostat, or electrical problem. Sometimes, there are more serious causes, including a failed compressor or frozen evaporator coil. In rare cases, a clogged filter or low refrigerant level can be the culprit, especially since many units are now built with safety triggers and mechanisms.
10. Older Unit
Most air conditioners are made to last between 15 and 20 years. Older systems can be inefficient. Once your unit turns 10 years old, it should be fully checked by a professional. When it turns 15, you should be considering replacement options.
