In this article, we’ll provide step-by-step instructions on how to troubleshoot a frozen AC unit so that you can get cool again in no time. We’ll also discuss the most common causes of an air conditioner freeze-up, as well as tips for preventing future issues.

So read on to learn more about what could be causing your air conditioning woes – and how you can fix them!

If your air conditioner is frozen, don’t wait! Contact a reliable HVAC company for professional air conditioner repairs and tuneups.

The Most Common Causes of an Air Conditioner Freeze-Up

When an air conditioner freezes up, the most common causes are:

Cause #1 — Low Refrigerant Levels

Refrigerant is the fluid that helps move heat from inside your home to outside. If there’s not enough refrigerant in circulation, then the evaporator coil can become too cold and form ice on it. To deal with this relatively common issue, you will need to contact an HVAC technician who can recharge or replace the refrigerant in your system.

Cause #2 — Clogged or Dirty Filters

The filter in your AC helps catch dirt and debris before they enter the system. Over time, these particles build up and create a blockage that restricts airflow over the evaporator coil. This causes the coil temperature to drop too low and form ice. To fix this issue, make sure to change out your filter regularly (every 1-3 months depending on use).

Cause #3 — Blocked Condensate Drain

Condensate drains carry excess moisture from around the evaporator coil away from your home. However, if these drains become clogged with dirt or debris, then water can back up into the coil and cause it to freeze over time. To fix this issue, make sure to inspect and clean out any blocked condensate drains regularly (about once every 3 months).

Tips for Preventing Future Issues

In addition to addressing any of the issues above when they arise, there are also some preventive measures you can take:

Tip #1 — Make Sure All of Your AC Registers Are Open

If any of them are closed off or blocked with furniture or drapery, then they may restrict airflow over the evaporator coil which could cause it to freeze up over time. So make sure that all of them remain open at all times!

Tip #2 — Inspect Ductwork for Leaks

Leaky ductwork allows conditioned air (and cold air) to escape before it reaches its intended destination – meaning that not enough cool air is making its way into your home. This could possibly cause issues with cooling efficiency – even leading to an eventual freeze-up if left unchecked for long enough periods of time. So have any leaking ducts repaired as soon as possible!

Tip #3 — Schedule Regular Maintenance Checks

Getting a professional HVAC technician out at least once per year is key when it comes to avoiding future issues with your AC unit including potential freezing problems down the line. They will be able to identify any potential problems before they become a larger issue – saving you from costly repairs or replacements later on.

All in all, it’s important to address any potential problems with your AC unit as soon as possible before they cause major damage. If you think your air conditioner has frozen up, then follow the instructions and tips above to troubleshoot and prevent future issues.

Who Should You Call if Your AC is Frozen?

When your AC unit has frozen up, it’s important to call a certified HVAC technician right away. A professional technician will be able to diagnose and repair the problem quickly, as well as help you prevent future issues from occurring. 

Professional technicians will have the specialized tools and experience necessary to identify any potential problems with your air conditioning system, such as leaking ductwork or low refrigerant levels and will be able to provide a reliable solution.

Homeowners should never attempt to fix an AC unit on their own – only qualified professionals should do so for safety and efficiency reasons.

How to Troubleshoot a Frozen Air Conditioner — Conclusion

Homeowners should always be sure to address any potential problems with their AC unit as soon as possible before they cause major damage. By following the step-by-step instructions and tips provided in this article, you can troubleshoot a frozen air conditioner and prevent future issues from arising.

Remember to check your refrigerant levels, inspect your filters regularly, clean out blocked condensate drains, make sure all of your registers are open, inspect the ductwork for leaks and schedule regular maintenance checks – these will help ensure that you stay cool all summer long!
