Air Conditioning problems tend to develop over time, and there can be many reasons why your system isn’t functioning the way it should. Many times, the problem you are having will fit into one of the five categories below. Being able to identify them will help you determine whether you can repair it yourself, or you’ll need to call an HVAC expert:

1. Wiring problems: corroded connections due to moisture and lack of maintenance, non-certified wiring, and shoddy electrical work can prevent your system from getting the power it needs to run. It can also trip your circuit breaker. Unless you are a trained professional, you should never attempt electrical air conditioning problems yourself — call an expert immediately.
2. Low refrigerant: Refrigerant is the chemical that is responsible for cooling the air in your system. Low levels of refrigerant are a sign of a leak or some other problem in your refrigerant system. If you frequently need a recharge, chances are the problem is a leak, and you should contact your HVAC professional and have it identified and fixed.
3. Outside fan not working: The outdoor fan is responsible for transferring heat from your home to the outside. If the fan does not work correctly, heat transfer will not occur, and your compressor may overheat and trip the unit’s safety overload. This is a severe condition that could damage the compressor. If this is happening, shut off your system immediately and call a professional.
4. Outside unit not working: This can be due to poor wiring, lack of power, or a faulty thermostat. Check your thermostat’s settings and batteries, and if that doesn’t solve the air conditioning problems, call an HVAC contractor.
5. Frozen coil: This can be due to clogged filters restricting airflow. Be aware that there are many other causes for a frozen unit. Changing your filters regularly is an essential part of air conditioning maintenance and should be done periodically. Changing your filters can prevent many problems. If you change your filters and are still experiencing problems, it could be low refrigerant or something more complex. Please turn off your system and call an HVAC contractor.

The best way to prevent these and many other problems is to schedule periodic maintenance with a trained HVAC contractor. These professionals know how to spot potential issues and fix them before they become a significant problem. Finally, if you don’t have a maintenance contract, you should consider one.
