Is Your AC Really Working? Key Signs It Might Be Faulty

An AC can malfunction or stop working for various reasons, some of which may be specific to your cooling system and others common to most units. Common signs that your AC may need maintenance include blowing warm air, weak airflow from vents, loud noises, or a malfunctioning thermostat. 

If you notice water leaking around your unit, strange odors, or a fan that isn’t working properly, these are also clear indicators that something is wrong. Routine AC maintenance and servicing can easily fix most issues, which can go a long way in preventing unexpected and expensive repairs.

Signs Your AC Needs Maintenance

Here are some signs that there is something wrong with your AC.

1. AC Blowing Warm Air

An air conditioner comforts your family during the hot and humid summer. It should keep you comfortable during the hottest months. If it blows warm air instead of cool, refreshing air, it’s time to call an HVAC technician.

2. AC Thermostat is Not Working

Your air conditioner’s thermostat is the system’s brain, as it tells the AC how much cool air to produce and ensures it’s performing correctly. If your AC runs only briefly before shutting off or doesn’t start, the thermostat might not be working properly. Since this issue involves complex electronic components, it’s best to call a professional to diagnose and fix it.

3. Weak Airflow from Vents

If your AC produces cool air but weak airflow, your system may struggle to cool the room effectively. It often points to a malfunctioning compressor or a duct issue. Regardless of the cause, it indicates that your AC needs maintenance. Regular tune-ups help identify and resolve these issues early, ensuring your system runs smoothly and efficiently for the long term.

4. Loud Noise Inside of the AC Unit

If you hear grinding, squealing, or scraping noises while your AC is running, it could indicate that a belt has moved out of position inside the unit. These sounds are a warning sign that something is wrong and should be addressed promptly to avoid causing further damage to the system’s components.

5. The Fan is Not Working

An air conditioner also won’t cool if the fan isn’t running. Here are a few things you can try to troubleshoot this:

• See if something like flipped switches or bad wiring stops the unit from getting power.
• Try resetting the air conditioner by flipping the reset button.
• After you’ve switched off the unit and unplugged it (if applicable), try spinning the fan blades clockwise and remove any obstructions.
• If the unit’s filter is dirty, clean it or replace it if necessary.

If none of these work, there is probably a problem with the control panel, internal control board, or other internal components. A common culprit is the capacitor, a small cylindrical device that sends jolts to start the motor. If the system is humming but the fans aren’t spinning, the capacitor must be replaced.

6. AC Leaking Water

Water accumulating around your air conditioner can indicate something is wrong. A leaking AC is likely due to a clogged drain line or a frozen coil. When water backs up, it can damage your floors, walls, and even the unit if not addressed. You should fix the leak immediately to avoid causing more damage. Have it checked by a professional to keep your system functioning efficiently in the long run.

7. Unusual Sounds

A well-functioning machine won’t typically produce noises that suggest something’s not functioning properly. Metal-on-metal sound, for instance, would indicate that the system needs more lubrication. Not addressing this problem could result in serious damage. Loose belts or damaged parts might also produce strange noises. Once again, a professional inspection can help with this.

8. Bad Odor from AC 

If you experience a musty or unpleasant odor from your air conditioner, it may be a sign that mold or mildew is developing within the system. Excess moisture in the ducts or cooling coil is usually the reason for this problem. Not only can these odors make your home uncomfortable, but they can also affect the air quality. Cleaning and inspecting the unit can help prevent mold and ensure the air in your home stays fresh.

Conclusion

Suppose your air conditioner is showing any of the signs mentioned above. In that case, whether it’s producing warm air, generating unusual sounds, or dripping water, it’s obvious that your system requires some attention. Scheduled AC maintenance is the key to ensuring your unit operates efficiently and preventing expensive repairs in the future. Fixing these problems at an early stage ensures your house remains cool and comfortable throughout the summer season.
