A humming sound from the air conditioner unit with no air seeming to come from the unit is a good indication that the fan has seized or is no longer working. Replacing the fan is relatively simple if you have a basic understanding of how the unit works, but if you are unsure contact a technician.

If you need emergency service for your air conditioning unit, beware. This can be costly. If you can live without it for just a day or so, you can schedule an appointment and get a lower price on the air conditioning repair that you need for your unit.

Each year before you begin to use your air conditioner, it is important to call a professional out to do the repairs that are needed on the unit. This may include simply cleaning and checking to make sure it works. But, it prevents potential problems later.
