Why is my Air Conditioner not Working?
Don’t know why your air conditioner is blowing hot air, or not blowing at all? Want to get down to the problem? Then you’ve landed on the right page. We’ve gathered some of the most common reasons as to why your unit would not be blowing correctly. There are many reasons as to why your HVAC unit wouldn’t cool properly.
Let’s Talk About your Thermostat
Your thermostat is the brain of your unit telling it what to do. You’d be surprised at how many calls there have been and all that needs to be done is moving something on the thermostat. First, make sure that the system is on cool and not on heat. If your fan is set to “auto” it means that your fan will still blow even if the air conditioner is not cooling the air. This could make it blow that hot air that you’re feeling. Also. make sure that the temperature is not too high when set on auto. This can cause a time delay for your unit to catch up.
Maintenance Needs to be Done
Dirty filters can often be an underlying cause of airflow restrictions. Your unit needs those filters to let the air pass through and catch all of the debris from the outside world. Once your filter fills up, it’s time to switch to a new one. A super dirty filter can trap your air and not let anything pass if there is too much debris in the filter.
Another possibility could be a dirty coil. The coil removes heat from the air so it comes out cool once its passed through. As there is a lot of moisture passing through the coil, it can sometimes create pinhole leaks in the copper or metal tubing. It may be hard to detect so our expert technicians know just how to get the job done right. There are multiple ways to detect a leak in your coil such as electronic leak detection and soap bubble detection. Soap bubble leak detection is pretty straightforward. You get a bottle with water and some soap, and when a bubble appears that is where your leak is.
Your condenser could also be dirty. Even a small layer of dust can effect your air conditioning system. Even having leaves around your condenser and having blockages around it can restrict airflow. Your outside unit should have at least two feet of clearance around it. You can also get your water hose and give it a spray down to ensure that there’s no debris or foliage stuck in it.
Usually we prefer you not to use a hose attachment, but if you must, stay at least a foot away from the coil itself to avoid damage. Here is a photo of an example of this.
