1. Air Conditioner Won’t Cool Your Home

The air conditioning system draws warm air from your home, cools the air, then blows it back into the house. If this system isn’t working properly, it won’t take long for you to lose your cool. This is one of the most AC problems in Cincinnati, and it can be caused by:

 

  • Low refrigerant
  • Frozen coils
  • Blocked return vents
  • Blocked air vents
  • Improper load balancing

Low refrigerant can be caused by improper initial charging, or by a leak in your air conditioner. Frozen coils and blocked ducts go hand in hand. Whether it’s a clogged filter, an obstructed return or closed vents, the warm, humid air can’t pass by the coils quickly enough. This causes ice to build up, obstructing airflow and overloading the system.

2. Faulty Electrical Systems

Other common points of air conditioner failure is the electrical system and its electronic components. Some failures can cause undesired operation, while others can completely disable the system. These include:

  • Malfunctioning thermostat
  • Failed sensors
  • Corroded contacts or connectors
  • Broken or shorted wires
  • Defective breakers

Defective thermostats or sensors can prevent proper operation and dirty electrical contacts can keep condensers and compressors from working. Improper or broken wiring can cause intermittent problems, and present a serious risk of injury. Undersized or defective breakers can trip, shutting the system down. You may feel air blowing from the vents without realizing that the external compressor is without power.

3. Noisy Air Conditioner

A noisy air conditioner can have a variety of causes. Many of which can be mitigated or avoided through routine maintenance.

  • Rattling or whistling vents
  • Squealing or whistling near the return
  • Thumping noises when the system starts and stops
  • Loud rattle or vibration when system starts and stops

Most vents have internal baffles that let you control the airflow. If those baffles are loose, they can move in the airstream, creating a rattling noise. If they’re closed too tightly, the air that is forced around them can create a whistling sound. Squealing or whistling from the return can be a sign of a failing blower motor. Thumps, rattles, and vibrations are generally caused by loose ducts and vents. As the system starts up, loose equipment can move around, making noises.
