Top 3 Reasons Why Air Conditioners Fail

  • Refrigerant leaks - Over time, the level of coolant in your A/C drops. The joints and seals in the coolant system are subject to vibration, temperature changes, and other environmental damage. If you have a leak, simply adding more coolant won’t solve the problem. If your A/C coolant levels are low, contact a trained technician to test the system and repair any leaks. Once your cooling system is leak-free, the technician will recharge the system with the precise level of coolant required. Remember, the manufacturer has designed your A/C to work with a specific level of coolant. If the system is overcharged or undercharged, it will not work at the peak-efficiency level, waste energy, and cost you money.
  • Poor maintenance - Air conditioners work by dispersing heat through the cooling coils. When the air filters become blocked or the cooling coils become dirty, the efficiency of the system takes a hit. The compressor and fans will have to work harder, and the overall system will run hotter, increasing wear and tear. These components become more likely to fail prematurely. Simply checking the coils for dust and dirt and replacing filters will have a significant impact on the performance and longevity of your HVAC system.
  • Electrical control failure - The mechanical systems of your air conditioner are subject to wear and tear. The compressor and fan controls can simply wear out, especially when the air conditioner turns off and on frequently (this is common when an air conditioner is too big for the space it is cooling). The corrosion of wires and terminals is also a problem in many air conditioners. The electrical connections and contacts should be checked regularly by a technician.


Now that you know what causes air conditioners to fail, you can see why simple and inexpensive maintenance and regular check-ups can keep your air conditioner working at its best and provide it with a long life. Call United Air Conditioning of Central Florida, Inc. today for more information.
