Listed are the 10 most common Problems and Repairs when your Air Conditioner will not work. Caution with high voltage electricity and moving parts if you are not comfortable Please Call a Professional. AC Repair is not as difficult as it may seem. Build self confidence in your Air Conditioning Troubleshooting ability by watching a few Youtube Videos.
the 10 most common issues and Repairs for when your Air Conditioner will not work
- Check your Thermostat settings to ensure that Cool is selected and the desired temperature is actually lower than the room temperature.
- Check your Air Filter. Having a dirty or clogged air filter can reduce air flow causing your air conditioner not to work and possibly freeze.
- Your Capacitor is drained and needs changed. A multimeter with a capacitance function is needed to check capacitors. Klein Tools MM400 Digital Auto-Ranging Multimeter: Temperature, Capacitance, Frequency, Duty-Cycle, Diodes and Continuity, 600V
- Feel the Larger Copper Pipe on your AC Unit. The Copper Pipe (Suction Line) should be sweating and cold to the touch during a hot day. If it is not cold, your compressor could be off (bad capacitor/ hard start kit) or low on Refrigerant.
- Your Breaker is Tripped. Be Careful because this usually indicates a problem with the compressor or wiring.
- Unit has a Refrigerant Leak. Bacharach 3015-8004 H-10 Pro Refrigerant Leak Detectors
- Check your Evaporator Coil and Condenser Coil. If your Evaporator Coil is dirty it can cause your system to freeze. If your outdoor Condenser Coil is dirty it can cause your Air Conditioner to lose its efficiency and not cool properly. DIY Cleaners are available at most hardware stores and a shop vacuum also helps.
- If you notice that your air flow is reduced check for AC coil for any frost. If your Coil is frozen, turn the thermostat to Off and the Fan to On. This will speed up the thawing process but will also produce a lot of water so make sure your condensate drain/ pump is operating properly.
- Make sure the indoor fan is working. Turn the Fan On and check the airflow with your hand over a vent. If there is no airflow there is likely an issue with the motor or fan relays. If there is little airflow your Evaporator Coil is most likely Frozen and/or Blocked.
- Your Outside Fan Motor is not rotating. With the unit off, try to spin the blade with a screwdriver it should spin freely. If it does not spin freely it is mostly likely faulty. A Condenser fan motor that spins freely but will not start with the unit on usually indicates a bad capacitor or power interruption to the motor.
If your Air Conditioner is more than 14 years old and needs a major repair, you would probably benefit by purchasing a new unit. All Air Conditioners are required to have a minimum efficiency rating, a unit older than 14 years old is probably a 10-12 SEER Rated Unit.
A new higher efficiency unit (14-20 SEER) is an investment on future energy savings. Visit our Home Page for Special Pricing on new Air Conditioning Units.
