Hey everyone!
I thought I'd post this on here real quick - my ac isn't blowing cold air and I know nothing about it to fix it but I thought someone may have some tips for me?

It's a very new unit it was installed right before we moved into the house, it's 3 years old.

I'd rather not call a pro until I absolutely have to as they are very expensive!

Thank you so much for your help in advance :)

    Check breaker at the breaker box make sure it didnt get tripped

    Turn it on and see if the outside unit is running

    Turn the switch to Fan and turn off the A/C for a few and let the fan run and after about 30min turn it back on and see if that makes a difference, make sure the coil isnt frozen

    If that checks out and still no cold air, I am out of ideas

    Thank you! I will do those things and let you know how things turn out.
    I also read somewhere it may just need cleaned?

    Is it a window unit or central HVAC?

    Either way, it is probably frozen. As stated above. Turn on fan only, no AC and let it run for a while (like 2 hours).

    You might want to open the front and take out and clean the filter. Most of the time they just rinse out. That's all I can think of.

    Could be frozen or need to be charged

    Here is a link to a page that describes exactly what to do for the problem you described with your central AC.

    There are step by step instructions on what to do, and if that doesn't resolve the problem, they say the unit might need to be recharged with refrigerant.

    Check it out:

    Good luck.

    Thanks again to everyone for their help! I went outside and decided that I should probably wait until my husband gets home, I'm a bit intimidated with it as I'm not much of a mechanic!

    I turned the ac to fan and ran it for awhile and it blew cold air when I switched it back to ac, thank goodness! Thanks again for all of your help!

    That means that the evaporator coil was frozen. That is an indication that you need to add freon to it (charge the unit.), or the filters need to be cleaned or changed.
