Has your AC stopped blowing cold air? Sometimes your air conditioner gives out on you and blows warm air. There are a few different reasons this can happen. The first reason your air conditioner may blow warm air is a dirty filter. You are supposed to change your filter every 30 days or so. A clogged filter restricts air flow the AC needs to function and will cause many issues. Filters are cheap and it is very easy to change so make sure you stay on top of it. Do you have ice on the AC? Ice on the AC can be a result of low refrigerant. The AC literally freezes up and will blow warm air. When is the last time you had your AC cleaned and checked? Having a dirty AC can cause it to blow warm air so make sure you get your AC cleaned and checked each spring. One of the last common reasons that the AC could blow warm air is your thermostat. Is it wired correctly? Is it on fan instead of ON? Are the batteries fresh? These are all things you should check with the thermostat should the AC blow warm air.
