Most Common Causes of AC Blowing Warm Air
Have you ever faced a situation wherein your AC suddenly started blowing warm air? Most of us cannot deny that we have been in situations like these where the AC started acting weird out of nowhere. One would consider themselves lucky to fix an issue like this with a change in the thermostat settings. But what if the thermostat settings are just fine and the issue is something else. Well, in this post, we discuss just that. Let us walk you through some of the most common causes of an AC blowing warm air.
1. Low (or Leaking) Refrigerant
A relatively common cause of an air-conditioner blowing warm air is a low or leaky refrigerant. Refrigerant is a liquid that runs through your AC, and its main job is to enable cooling. The refrigerant’s job is to absorb environmental heat and provide cool air. A leaking refrigerant potentially lowers the system’s cooling power (depending on the size of the leak). Do NOT put in more refrigerant without repairing the leak; it might result in costly repairs in the near future. A good idea would be to leave the job to a technician.
2. Dirty Condenser Coil
A dirty condenser coil could be one of the many reasons your AC is blowing warm air. A condenser coil’s job is to release the heat outside. But in the process, it tends to get exposed to all sorts of outdoor elements (dust, foliage, trash, et al.). This, in turn, affects the coil’s functioning, thereby leading to your AC throwing warm air.
3. Clogged Air Filter
It may sound strange, but the fact is that your air conditioner relies on the warm air of your room for its cooling. The AC absorbs warm air from the room, cools it down with the refrigerant and cooling coils’ help, and then throws it (in the form of cooler air) back into the room. But during the process of absorbing air from your room, the air filter removes dust or any other contaminants from it. In this process, the air filter tends to get clogged, reducing the amount of warm air that an AC can absorb. As a result, the cooling gets hampered. To avoid this, you must clean your air filters on a regular basis.
4. Duct Issues
If your AC is blowing warm air, it could be a duct-related issue. The most common duct issue is closed or blocked vents that don’t allow ducts to throw back the cool air into the room. Another duct-related issue is the duct getting clogged due to lack of maintenance. If you have been neglecting your air conditioner’s maintenance, the chances are that your AC duct has accumulated dust and debris, which is preventing proper airflow. Similarly, any leaks, cracks, or holes in the ductwork can lead to loss of cool air from the system, thereby resulting in your AC throwing warm air.
