Common Air Conditioning Repair Needs

Does your AC make a loud or strange noise during operation? Are your energy bills higher than they have ever been? Do you find that your home is only unevenly cooled during the summer months? It sounds like you may have a problem. It’s important to keep an eye on your cooling system during its service life so that you can address any issues that might arise. Like all mechanical systems, your air conditioner endures its fair share of wear and tear over the years and making sure that any issues are repaired immediately will keep your system in good working order. In today’s post, we’d like to look at some common repair needs that might befall your AC.

As a general rule of thumb, it’s better to be safe than sorry. Your AC is a major investment and it needs to be taken care of to last as long as it should.


  • Frozen evaporator coil. Your indoor evaporator coil is responsible for cooling your indoor air. As cold, liquid refrigerant moves through the coils, it absorbs the thermal energy from the air that passes through the indoor air handler, but this process only works if the coils are clean. If your coils are dirty or in any way damaged, then your coils could freeze up as the cooling lingers. If you have low refrigerant, then this could also lead to frozen evaporator coils.
  • Loud or strange noise. It’s important that you take any loud or strange noises coming from your AC seriously. If you notice the development of any unexpected sounds, then make sure you get in touch with your local HVAC professional. Various sounds can occur. For example, a banging noise is likely a loose or damaged component within your indoor or outdoor housing, while a hissing or whistling noise could be an air leak.
  • High energy bills. Take stock of any abrupt changes in your utility bill during the summer months. If it seems that something is not right and your bill is much higher than normal, then there could be an issue with your air conditioner.
