Common Air Conditioning Problems

Even the most reliable and well-maintained air conditioning systems can face occasional problems. In these situations, it’s important to know who to call when you require repair services. Common air conditioning problems include:

  • Indoor leaks around your AC system - Typically, this means that you have a clogged condensate pipe.

  • Outdoor leaks around your condenser - Outdoor leaks that don’t quickly resolve on their own will require professional AC repair services.

  • AC refrigerant leaks - Refrigerant leaks can be the result of low refrigerant and/or damaged pipes. A professional can help you diagnose the exact problem.

  • Dirty air filters and ductwork - Without regular maintenance and filter changes, HVAC systems can become overburdened with debris and poor airflow.

  • Frozen evaporator coil - If this is a chronic problem, you will need to consult with a professional technician to diagnose and repair the source of the frozen evaporator coil.

  • Electric control and/or thermostat failure - You may need to check the electrical connections or replace your thermostat. A professional can help you figure out the problem and set you up with a maintenance plan for prevention.

  • The AC fan isn’t functioning properly - AC fan issues can be complicated, so it’s important to turn to a professional if you’ve noticed this issue.
