With temperatures finally on the rise, many homeowners are turning to their air conditioning system to get a little relief. Unfortunately, sometimes problems arise and you find that your central air conditioning system is simply not providing the cooling benefits you need. There can be many reasons why your air conditioner is not providing sufficient cool air, one of them being that your central air conditioner needs charged. Fortunately, you can save time and money by doing a little trouble shooting to determine if the problem can be resolved by having freon charged by a professional HVAC technician.
One of the first things you should do when you notice that your air conditioner is not cooling is to make sure you are actually running the air conditioner and that it doesn’t need to be reset. Turn your air conditioner on and set the thermostat to 80˚ F and let it run for approximately 30 minutes, then turn the thermostat down to 65˚ F and let your air conditioner run for another 15 minutes. This will help ensure your air conditioner is reset and can begin cooling your home if this was all that was necessary. If a reset was needed, you should quickly begin to notice a change in temperature. If not, it’s time to begin a little troubleshooting to determine the problem.
Start by making sure the fan for your outside unit is running. You should be able to take a look at the unit and see the fan going around, never stick your hands or anything else inside to see if it is moving. If the fan isn’t running, chances are the motor has burned out, in which case, you are going to need a professional HVAC technician to provide the necessary repairs.
If the fan is running, your next step is to check the thermostat. A professional HVAC technician can use an Ohm meter to determine if your thermostat is functioning properly; however, if you notice that your home is cooler than the outside temperature, you might have a broken thermostat. Again, checking thermostat and providing the necessary repair or replacement should be left to a trained professional.
Another important troubleshooting tip is to place your hand over one of the air vents. It is important to be sure that you are not doing this over a cold air return vent, but rather, over a vent that typically blows cool air into your home. With the air conditioner running, place your hand over the vent and check to see if the air is cool. If the air coming out feels warm or room temperature, you most likely need to have your unit charged. Contact a professional HVAC technician for charging your air conditioning unit. This is not something you should do on your own.
