Some air conditioning issues will inevitably require the services of a professional contractor. However, there are also several common issues that can be corrected on your own using a few basic troubleshooting steps. This is often the case for individuals who find that their air conditioner is blowing out warm air. If you are currently experiencing this problem, taking a few minutes to complete the three troubleshooting steps below can potentially prevent you from needing professional assistance. 

Step #1: Check For Evidence Of Frozen Coils

While you may think that frozen coils would produce even colder air, the fact is that air is often unable to circulate around these frozen coils and can actually result in your AC unit blowing out warm air. In order to determine whether or not this could be the issue, you will want to look for condensation on or around your indoor unit. If you spot any of these signs of frozen coils you will want to turn off your AC system for several hours in order to allow time for the coils to thaw. Placing a space heater near the unit can also assist in the thawing process, however, you should not apply heat directly to the unit itself.

Step #2: Clean Or Replace Your Air Filter

A clogged air filter can also prevent air from properly cycling through your AC system and can result in warm air flowing through your air vents. In order to correct this issue, you will need to clean or replace your air filter. Completing this task every month or two can help you to avoid this particular issue in the future.

Step #3: Clean Your Outdoor Condenser

The final step to help restore cold air flow through your air conditioning system is to make sure your outdoor condenser is clean. The best way to complete this task is to begin by clearing away any overgrown grass, weeds, or other debris from around the unit. This should be done by hand in order to prevent any damage to the protective cage that surrounds your condenser. Once you have cleared away any large pieces of debris you should use a garden hose or a bucket of water to wash away any dust or dirt.

A Final Thought

While the need to reach out to a professional HVAC contractor will be quite obvious if these troubleshooting steps have not resolved your air conditioning problems, you may still wish to make this call even if your air conditioner is now working. While these troubleshooting steps may get your air conditioner back up and running, they may not address the underlying cause that created the problem in the first place. For instance, while defrosting frozen coils will get your AC unit back up and running, you are likely to experience this problem again in the future if you do not resolve the underlying issue that caused the coils to freeze in the first place. Consequently, it is always best to follow up with professional maintenance even if you are able to temporarily resolve the issue on your own. For more information, contact an AC contractor.
