Basic AC Repair

Summer is here, which means our AC units are going to be working overtime for the next few months. This also means our air conditioners need to be in tip-top shape to keep us cool during these warm, sunny days. If you suspect your AC unit doesn’t seem to be working properly, there may be a simple solution.

In an effort to save you time and money, let’s take a look at a few basic steps you should check for before calling in a professional.

Check to Make Sure Your Thermostat is on the Proper Setting.

Along with a thermostat, most AC units contain three main parts: The indoor unit or furnace, the coil connected to your furnace, and the outdoor unit or compressor.

First, check to see if your thermostat is on the “cool” setting.   While this may seem like a fairly obvious suggestion, making sure your unit is on the proper setting will help alleviate a lot of stress and confusion in the long run.  Also, remember to check your indoor unit’s filter, as a clogged filter can lead to your unit working well below par.  If your filter is clean, dry and dust-free, and the unit is on the correct setting, your next step is to check the room’s actual temperature.

Compare the Temperature on the Thermostat to the Temperature in the Room

Take a minute to make sure your room is significantly warmer than the temperature listed on your thermostat.  If, indeed, the degrees on your thermostat do not register to the actual temperature in your room, the problem may be with either your indoor or outdoor AC unit.

Examine Your Indoor AC Unit

Check both your indoor and outdoor AC units to see if the fans are running.

  • If both fans are running, then it’s possible you may be low on Freon, a coolant that regulates the air temperature.  Be sure to consult a professional if you believe your Freon levels are low.
  • If both fans are off, then there may be an internal problem which will also require professional assistance.
  • If only one fan is on, then problem may reside elsewhere.

Turn Your AC Unit Off and Check Around the Unit

Because one fan may be working and the other is not, there may be a problem with your circuits or the fan’s internal motor. If this is the case, you’ll need to call to get it serviced.

Turn your AC unit off before checking the wiring and other internal specifications.   If you find no problems with the wiring, check around your outdoor unit for signs of condensation and other buildup.  A common problem with AC units during summer months is that they are constantly running.  Frequent usage can lead to your unit “freezing up,” causing the lines that go along your outdoor unit to accumulate frost or ice.  If you see any signs of frost build up, or a puddle of water along your outdoor unit, shut your AC system off and wait for the ice to melt.  Once the ice has melted, turn your AC unit back on to make sure it is functioning properly.

Keeping your home nice and cool is a necessity during this time of the year, and if you’re anything like me, you like to have your home set to a nice cool temperature.   Before checking to see if you’re AC unit is in need of repair, check to make sure your unit is covered by your home warranty.

  1. Good and helpful post, I just feel reminiscent of our air conditioning. We had recently made ​​until much stress with our filters and clean but it was just too warm.

    Only after we had consulted experts, the room temperature was back to normal. But you’re right, it was pretty expensive for us. Again we will hopefully not happen.
