“Why is my air conditioner not blowing cold air?”

Here at Neerings Plumbing & Heating, that’s one of the most common questions we hear . If you recently tried switching on your AC for the first time this year and had the unpleasant surprise of no cool air, don’t be in a huge hurry to call for Salt Lake City AC repair. In many cases, fixing the problem may be easier than you think.

What to Do When Your Air Conditioner Isn’t Blowing Cold Air

Warm Air Coming from Supply Vents

If there isn’t any air at all coming from the supply vents, skip to the next section. If air is coming out of the supply vents, but it isn’t cold, there are a few things you can try:

Check the Thermostat Fan Setting

Air Conditioner Not Blowing Cold Air

Is your air conditioner blowing cold sometimes but warm at other times? If so, make sure your fan is set to “auto” – not “on.” If it’s set to “on,” the air conditioner will blow air even when it isn’t being cooled.

Replace Your Filter

A dirty air filter could be to blame for warm, weak air. When the filter is dirty, it can block air from reaching the air filter. Ideally, you should be replacing you filter a couple times each year, and if you haven’t changed yours recently, that could be your problem. Regular AC maintenance like filter replacements are essential to the function of your system.

Inspect the Outside Unit

Dirt and debris can build up around your AC’s outside unit, especially during the winter months when the AC is not in use. If yours is dirty or being smothered by a large shrub or tree, do some cleaning the give the unit some breathing room. If you notice that the outside fan isn’t working, you’ll need to call a professional.

No Air Coming from Supply Vents

Check Your Thermostat

Make sure the temperature is set at least 5 degrees lower than the current temperature of the room. Also, make sure the thermostat is set to “cool.” It seems simple, but there’s always a possibility that another family member may have turned the unit off or set it to “heat.”

Check Your Air Filter

A dirty air filter can completely block airflow. This can cause the inside unit to freeze up. If your filter is excessively dirty, replacing it could solve the problem.

Make Sure There is Electricity Going to Your AC

Check switches by the compressor in the outside unit, at the air handler in the inside AC unit and at circuit breakers in your electrical panel. If any switches are turned off, there could be a problem with the unit. For example, if your AC is overheating, it could cause the circuit breaker to cut power to the unit.

If you’ve exhausted all of these options and your AC still isn’t blowing cold air, a more serious problem could be to blame. The unit may be low on refrigerant, and this is a problem that needs to be left to the professionals.
