Some air conditioner issues you can troubleshoot at home, while others need expert attention. If your unit is malfunctioning and you're not sure if you need an AC repair, call an expert for some guidance. The following signs also indicate the AC needs professional repair. 

The AC Makes Unusual Noises

It's normal for an air conditioner to make some noise, but when it's loud or unusual, it can indicate a problem. A loud screeching noise usually means a malfunctioning fan motor. Rattling, humming, or buzzing noises suggest loose or malfunctioning components. An AC service technician can diagnose the noise and fix it safely.

A Spike in Energy Bills

If you notice your energy bills are getting higher and you're not using additional appliances, your air conditioner may be getting old. The system could also have a broken thermostat switch or leaky ductwork, which are all issues best left to AC professionals. 

The Unit Blows Hot Air

A common reason for warm air is dirty condenser coils. These coils release heat from the refrigerant to facilitate cooling, so the system starts working inefficiently when the coils are blocked. Condenser coils are part of the refrigerant system, so a technician will have the knowledge and experience to clean and maintain them. 

Odd Smells

You and your household breathe in the air coming out of your air conditioner. A musty smell can indicate mold or mildew growth, while a burning smell could be a burned-out wire. Either way, any smell is not good and should be checked out by an AC technician.

Little to No Air From Vents

The compressor is the powerhouse of your AC unit, and when it malfunctions, it can affect the airflow. Other reasons for poor airflow include a dirt-clogged fan, low refrigerant levels, or an issue in your air ducts. Since there could be multiple causes, it's better to get the right diagnosis from a professional.

The Unit Is Leaking

Factory defects, mechanical vibrations, and daily wear and tear can lead to refrigerant leaks. Water near or coming from the unit may be due to a leaking tube that disposes of condensation. Get assistance from a skilled technician to fix any leaking issue.
