Why is My Air Conditioner Not Blowing Cold Air?

When the temperature reaches 100 degrees on a summer day in Columbus, Ohio, you really need your air conditioner. When the heat and humidity are oppressive is not the time to be asking, why is my air conditioner not blowing cold air?  If this should happen to you, here are a few useful tips.

What to Do if Your Air Conditioner Is Not Blowing Cold Air

Many times when this happens you can easily fix the problem yourself. When you cannot fix the issue with a few simple measures it is time to call a professional air conditioning service.

Check the Temperature Settings

If you have an HVAC system with controls for both heating and cooling it might be the case that your settings were adjusted for a central Ohio winter and simply need to be reset. Check the AC temperature settings and adjust them if needed. The ideal temperature setting for air conditioning is 78 degrees Fahrenheit as it is the most energy-efficient setting and will give you relief on a hot summer day in Columbus, Ohio. Some folks prefer lower settings but be aware that setting to 72 degrees or lower will increase your cooling costs by 50% or more. If you have a programmable thermostat, you may need to set it for both heating and cooling.

Check Your Filters

In order to cool your home, the air conditioning system blows air across its evaporator coils. If you have dirty air filters the air flow is blocked, the coils get too cold and frost or even ice will form which will slow the air flow more. A clue might be that the air flow seems to be reduced but just check the filters. Clean the filters in the spring and then as often as every two weeks, depending on how fast dust and grime accumulate.

Check the Outside Unit of Your AC System for Debris Buildup

If your air conditioner is not blowing cold air the problem might be debris blocking air access to your outside unit. You may have done an excellent job raking leaves in the fall or spring but you may not have removed leaves and other debris blocking the air conditioner unit. Turn off the unit or turn off the circuit breaker to the unit before you start. Then use a shop vacuum to remove debris around the unit. Check the metal fins to make sure that they have not been bent or damaged. Other steps include removing the fan and washing out the fins from inside out with a garden hose. But, how we are getting into good reasons to call a pro!

How to Prevent Air Conditioner Problems on a Hot Central Ohio Day

While the steps we mentioned may be enough to start cooling your home again, your best bet is to routinely have you unit serviced every spring. By doing this you will make sure that your AC is in top condition, ducts are cleaned, filters are cleaner or replaced, coolant levels are OK, and there are no other problems that will cause you to have no AC on a hot summer day in Columbus, Ohio.
