10 Most Common AC Problems And How To Troubleshoot Them

Air conditioning is a crucial aspect of your home’s comfort, especially during the hot summer months. As a homeowner, you are likely aware that AC units can experience problems from time to time. Knowing how to perform AC troubleshooting saves you money and prevents costly breakdowns. 

All Around Mechanical is a trusted HVAC contractor in Ridgefield, WA. We provide top-notch AC repair and services to our customers. 

Below are the ten most common AC problems and how to troubleshooting them:

1. AC Not Turning On

Your AC unit may not be turning on due to a tripped circuit breaker, blown fuse, or a faulty thermostat. Check your circuit breaker and reset it if necessary. If the breaker keeps tripping, call our professional. Check the thermostat settings and replace the batteries if necessary.

2. Weak Airflow

Dirty air filters, blocked ducts, or a malfunctioning fan motor can cause weak airflow in your air conditioning system. Replace the air filter and check for any blockages in the ducts. If the fan motor is malfunctioning, call our professional for repair.

3. AC Not Cooling Enough

Dirty air filters, low refrigerant levels, or malfunctioning compressors can lead to your air conditioning unit being unable to cool enough. You can troubleshoot this issue by replacing the air filter and checking the refrigerant levels. If you live in the area, call a professional like All Around Mechanical for AC repair in Woodland, WA, for assistance. We can take a look at your broken compressor and provide the next best course of action.

4. Leaking Water

If your air conditioner is leaking water, it can be caused by a clogged condensate drain line, a faulty condensate pump, or a frozen evaporator coil. Check the condensate drain line for any clogs and replace the condensate pump if necessary. If the evaporator coil is frozen, turn off the unit and let it thaw before restarting.

5. Strange Sounds

If your AC unit makes strange sounds, such as buzzing, rattling, or squealing, it could be due to loose components, a malfunctioning fan motor, or a faulty compressor. Tighten any loose components and replace the fan motor or compressor if necessary.

6. Foul Odors

If your AC unit produces foul odors, a dirty air filter, mold growth, or a dead animal in the ductwork can be a cause. You should replace the air filter and clean the ductwork regularly to remove any mold growth. If there is a dead animal in the ductwork, call our professional for removal.

7. Frozen Evaporator Coil

If your AC unit has a frozen evaporator coil, it could be due to low refrigerant levels, a dirty air filter, or a malfunctioning blower motor. Check the refrigerant levels, replace the air filter, and replace the blower motor if necessary.

8. Short Cycling

If your AC unit is short-cycling, turning on and off frequently, it could be due to different reasons, such as a dirty air filter, low refrigerant levels, or a faulty thermostat. Replace the air filter, check the refrigerant levels, and replace the thermostat if necessary.

9. High Humidity Levels

If your AC unit is not controlling the humidity levels in your home, it could be due to a malfunctioning condenser or evaporator coil or a clogged condensate drain line. 

10. AC Unit Overheating

If your AC unit is overheating, it could be due to a dirty air filter, low refrigerant levels, or a faulty fan motor. Replace the air filter, check the refrigerant levels, and replace the fan motor if necessary. Overheating can also be caused by a dirty condenser coil, which can be cleaned by a professional.
