AC Troubleshooting Tips

There is nothing worse than when your air conditioning unit stops working at the moment you need it to relieve you from rising temperatures. While a lot of air conditioning repairs require you to hire a HVAC professional, there are actually some repairs that you can do yourself in order to save money. Here are some common problems for your air conditioning unit and troubleshooting tips can help you diagnose and resolve those problems.

The A/C unit isn’t running

  • Before anything else, check to see that the unit is plugged in. If it is and the unit still won’t run, check for a blown fuse or tripped circuit breaker. Restore the power and see if it starts. In addition, a thermostat that isn’t properly set will prevent the unit from working. Lower the thermostat by five degrees and see if it starts. If it is not starting, then the problem may be a faulty motor or compressor. This will require you to hire a professional.

The A/C unit is turning on and off

  • A dirty evaporator, as well as a dirty or blocked condenser unit, will prevent your unit from staying on. Giving the entire unit a good cleaning and removing any obstructions can resolve this problem.

Cold air is coming out, but not enough to cool home

  • If the central air conditioning unit doesn’t seem to be cooling your home adequately, start by lowering the thermostat five degrees. If that doesn’t fix the problem, you may once again be dealing with a dirty evaporator. Carefully clean the evaporator and let it run for a few hours. If the problem continues, you may have to replace the unit.  It is best to consult a professional before making this decision. Keep in mind that extremely hot temperatures and the size of your home may affect the performance of your air conditioner.

The A/C unit is running, but not releasing cold air

  • If you don’t feel any cool air coming out of your unit, you should first check the thermostat to make sure that it is at the right temperature. Next, check to see if the condenser is dirty or blocked. Weeds, grass, and other debris can block the condenser. If you remove the blockage and you are still dealing with the problem, this can be the result of a faulty compressor, or low coolant/refrigerant. These are problems that you will need a professional to fix.

Proper routine maintenance and cleaning of your air conditioning unit are things you can do on your own, and hopefully these troubleshooting tips will help you deal with issues before spending money on a professional repairman. Make sure to begin your air conditioner troubleshooting at the thermostat by ensuring that the thermostat is on cool and that it is set lower than the actual room temperature. This is important to ensure that there really is a problem.
