Does Your A/C Unit Need a New Motor?

Friday, October 3rd, 2014 at 7:33 pm

Your air conditioner is a complicated piece of equipment, but it is also one of the most important pieces of equipment in your home. When you live in places like Glendale and Phoenix where the temperatures routinely reach the triple digits in the summer, any disruption in service could create not just an extremely comfortable situation, but also one that is hazardous to your health.

One of the most common parts to need repair or replacement is the motor. While you don’t want to rebuild the motor or repair it yourself, you should be aware of the signs that there could be a problem so you know when to call an experienced air and heating contractor in Phoenix.

Some common things you might notice when there is a problem with your AC motor include:

  • Humming sounds or other unusual noises.
  • Your AC stops running after a few hours, or it runs only intermittently.
  • There is no cold air blowing out of the unit.

When your air conditioner stops putting out cold air that’s a sure sign that you need to have it looked at right away. However, you may think that issues like unusual noises or intermittent operation are “no big deal” or maybe even just something to be expected from an aging unit.

The earlier you address any of these issues, the more likely you are to be able to repair your cooling unit and add years to its life. If you let these issues linger, they could lead to even bigger problems for your air conditioner, which could require extensive repairs or even a total replacement.

If your air conditioner is humming or buzzing, it likely means that the motor is being powered but its blades are not working. Several things could be causing the problem, such as a bad capacitor, relay switch or motor shaft. Replacing a simple part is far less work (and money) than replacing the whole air conditioner motor.

If your air conditioner is working but cuts out periodically, it may be because the motor is overheating. There could be a problem with the relay or the motor itself. You’ll need to talk with an experienced technician to find out what is causing it for sure. Replacing a relay will cost far less than replacing or rebuilding the motor.

Finally, if your air conditioner is not putting out any cold air, it’s because the blower motor is not working. There could be a bad connection, or you could have a problem with the relay or the motor. Again, working with an experienced technician can help you get to the bottom of the problem to know for sure what is causing it.
