As temperatures soar, the last thing you want is to have your AC blowing out warm air. This is why homeowners tend to have the same AC repair question and concern: why is my vent air not cold? But did you know there are ways you can “troubleshoot” or resolve this on your own?
With that said, the first thing you should do is learn the common causes of warm air from vents before we go through what you can do. The most obvious one would be having a dirty AC system. Over time, dust and debris can accumulate in your filter, preventing proper airflow. At the same time, this may also increase your electricity bills because it will make your AC to work harder than it should. This can lead to reduced cooling capacity, which is why the air blowing from your vents is not cold anymore. Consequently, when it comes to AC systems, you may find a dirty air filter or dirty condenser unit. The good thing is that this is relatively easy to resolve on your own as you will either need to replace your air filter or clean the AC unit. You could do this yourself, or the much better option, to have the professionals clean it thoroughly.
One other common AC repair question that we encounter is about refrigerant levels. Refrigerant is the substance that cools the air in your AC unit, and if levels drop too low, your AC won’t be able to properly cool your home. This can be caused by leaks in your AC system or simply by natural wear and tear over time. For this particular issue, this is when we would highly recommend have an AC technician to fix this problem. A professional can diagnose the problem and add more refrigerant to your system if needed. It’s important to address low refrigerant levels as soon as possible to prevent further damage to your AC unit and ensure proper cooling.
Aside from that, another important thing to check is your thermostat. This is the control center for your AC unit, and if it’s not working properly, it can cause warm air to blow from your vents. To troubleshoot this issue, start by checking your thermostat’s batteries and settings. Make sure it’s set to “cool” and the temperature is set to your desired level. If this doesn’t work, then it’s time to call a technician as it may be due to loose wires.
What AC Repair Question to Ask Your Technician
Overall, the rule is that if you are not comfortable with working on something with your AC, that is a sign that you need to call the pros. This is especially the case when it has to do with electrical issues or malfunctioning compressors. It can be dangerous. Since you don’t really need to know all the technical aspects of fixing the AC, your AC repair question for your HVAC technician would be how much it would cost. As long as you have a trusted and reputable technician, there is really nothing more you should ask.
