Cooling Crisis: How to Troubleshoot Your AC Like a Pro

As the summer heat reaches its peak, the last thing you want is for your air conditioning (AC) system to fail. While it’s always best to call in a professional for major issues, there are some common AC problems that you can troubleshoot on your own.

In this blog post, we’ll cover five of the most common issues and provide you with tips on how to fix them like a pro. Remember, if you’re ever in doubt, don’t hesitate to contact the experts at Holstead’s Air Conditioning and Heating for assistance.

1. Dirty or Blocked Air Filter

One of the most common causes of AC problems is a dirty or blocked air filter. A clogged filter can restrict airflow, causing your system to work harder and less efficiently.

To fix this issue:

• Turn off your AC system and locate the air filter.
• Check the filter for dirt and debris. If it’s dirty, replace it with a new one.
• Make sure to replace your air filter every 1-3 months, depending on usage and the type of filter you have.

2. Frozen Evaporator Coil

A frozen evaporator coil can cause your AC system to blow warm air or stop working altogether. This issue is often caused by low refrigerant levels or poor airflow.

To troubleshoot a frozen evaporator coil:

• Turn off your AC system and let the coil thaw for a few hours.
• Inspect the coil for damage or leaks. If you suspect a refrigerant leak, contact a professional for repair.
• Ensure proper airflow by checking for and removing any obstructions around your AC unit.

3. Faulty Thermostat

A malfunctioning thermostat can cause your AC system to run constantly or not turn on at all.

To troubleshoot a faulty thermostat:

• Check the thermostat’s settings to ensure it’s set to “cool” and the temperature is set below the current room temperature.
• Replace the thermostat’s batteries if they’re low or dead.
• Consider upgrading to a programmable or smart thermostat for better energy efficiency and control.

4. Leaking Ducts

Leaking ducts can cause a significant loss of cool air, leading to higher energy bills and reduced comfort.

To troubleshoot leaking ducts:

• Inspect your ductwork for visible signs of damage or disconnections.
• Seal any leaks with duct tape or mastic sealant.
• Consider having your ducts professionally cleaned and sealed by a qualified HVAC technician.

5. AC Unit Not Turning On

If your AC unit isn’t turning on, there could be a few different causes.

To troubleshoot this issue:

• Check your circuit breaker to ensure it hasn’t tripped. If it has, reset it and try turning on your AC again.
• Ensure your thermostat is set correctly and has power.
• Inspect your AC unit’s wiring for any signs of damage or disconnections. If you find any issues, contact a professional for repair.
