As the summer heat intensifies in Philadelphia, a functioning air conditioning system is not just a luxury; it's a necessity. However, when your air conditioner malfunctions on a scorching Philly day, knowing the basics of air conditioning repair and when to call in professionals can make all the difference.

Common Air Conditioner Issues

  1. Faulty Wiring: Improper, haphazard, or old wiring can prevent the system from receiving the power it needs to function properly, or worse, pose a fire hazard.

  2. Low Refrigerant Levels: Refrigerant (the fluid essential for cooling the air) levels that are too low indicate a leak or a problem with the refrigerant system.

  3. Outside Fan Not Working: The fan on your outdoor unit transfers the indoor heat outside. If the fan isn’t working correctly, proper heat transfer cannot occur, leading to potential compressor damage and overheating.

  4. Frozen Coil: A frozen indoor coil suggests issues with airflow, such as obstructions caused by dirt or low coolant levels.

DIY Fixes vs. Professional Help

DIY Approaches:

  • Cleaning: Regularly cleaning your air conditioner’s filters and coils can prevent many problems.
  • Checking Thermostat: Sometimes, the issue is as simple as the batteries in your thermostat needing replacement or the thermostat not being set correctly.

Professional Help:

  • Electrical Issues: Any problem involving wiring should be handled by a professional to avoid the risk of shock or further damage.
  • Refrigerant Leaks: Dealing with chemicals like refrigerant requires special training and certification, which is best left to professionals.
  • Component Replacement: Replacing major components, such as fans or compressors, should be done by a technician who can ensure that the system functions efficiently afterward.

Choosing the Right Service

Preparing for a Technician's Visit

To make the most of a service call:

  • Describe the Problem: Be as detailed as possible about what is wrong with your AC system.
  • Clear the Area: Ensure that the technician has easy access to the air conditioner.
  • Maintenance Records: Having records of past maintenance available can help the technician diagnose problems faster.


Understanding the common issues with air conditioners and knowing when you can handle a problem yourself versus when to call a professional can save you time and money. As temperatures rise, keep your Philadelphia home cool and comfortable by maintaining your air conditioning system properly and knowing who to call when you need help.
